Payback Period

 What Is the Payback Period?

The Payback Period is the amount of time required for an investment to recover its initial cost from its cash inflows. In other words:

How long does it take to get my money back?

Payback Period= Initial Investment / Annual Cash Inflow​

Interpretation:

• A shorter payback period means faster recovery of capital

• A longer payback period indicates higher liquidity risk

---

Discounted Payback Period

What Is the Discounted Payback Period?

The Discounted Payback Period improves on the traditional payback method by considering the time value of money.

Instead of using raw cash flows, it uses discounted cash flows (present values) to determine how long it takes for the investment to recover its initial cost.

How It Works

1. Choose an appropriate discount rate

2. Discount each future cash flow to its present value

3. Add the discounted cash flows cumulatively

4. Identify the time when the cumulative total equals the initial investment

is better than Payback period

• Accounts for inflation, risk, and opportunity cost

As a result, the discounted payback period provides a more realistic measure of capital recovery than the simple payback period.

---

Pitfalls of the Payback Period

Despite its popularity, the payback period has several important weaknesses:

1. Ignores the Time Value of Money

The traditional payback period treats all cash flows equally, regardless of when they occur. This can significantly distort investment decisions, especially in high-inflation environments.

2. Ignores Cash Flows After Payback

Any cash flows received after the payback period are completely ignored. As a result, highly profitable long-term projects may be rejected.

3. No Measure of Profitability

The payback period focuses only on capital recovery, not on value creation or profitability.

4. Arbitrary Cutoff Point

Managers often select a maximum acceptable payback period arbitrarily, which may lead to suboptimal decisions.

---

💬Payback vs. Discounted Payback vs. NPV

Criterion	Payback Period	Discounted Payback	NPV
Time value of money	No	Yes	Yes
Considers all cash flows	No	No	Yes
Measures profitability	No	No	Yes
Ease of use	Very easy	Moderate	More complex

---

Final,

The payback period and discounted payback period are best used as risk and liquidity indicators, not as final decision tools.

For financial decision-making:

1. Use payback measures to assess how quickly capital is recovered

2. Use NPV to determine whether an investment truly creates value

When used together, these methods provide a more complete picture of an investment’s risk and return.

Cash Flow Valuation and Present Value

 In finance, investors and businesses usually receive more than one cash flow over time. To evaluate such investments, we rely on the concept of present value (PV).

The present value of cash flows is equal to the sum of the present values of each individual cash flow. This approach reflects the fundamental idea that money has a time value — receiving money today is more valuable than receiving the same amount in the future.

---

What Is Cash Flow Valuation?

Cash flow valuation is the process of determining the value today of cash flows that will be received in the future. This is done by discounting future cash flows using an appropriate discount rate that reflects risk, inflation, and the opportunity cost of capital.

---

 Investor Indifference

Consider an investor who can choose between two alternatives:

• Receiving $1,432.93 today, or

• Receiving the following future cash flows:

  • $200 in one year

  • $400 in two years

  • $600 in three years

  • $800 in four years

If the discount rate is chosen correctly, these two options have the same present value. In this case, the investor is said to be indifferent between receiving $1,432.93 today and receiving the future cash flows listed above.

This example illustrates how future cash flows can be translated into an equivalent value today.

---

Net Present Value (NPV)

Net Present Value (NPV) is defined as the present value of expected future cash inflows minus the investment’s costs (cash outflows).

In simple words, NPV measures how much value an investment adds (or destroys) today.

Interpreting NPV:

• NPV > 0: The investment increases shareholder wealth

• NPV = 0: The investor is indifferent; the investment earns exactly the required return

• NPV < 0: The investment reduces shareholder wealth

For example, if an investment has an NPV of $13.14, it means the project increases the present value of the firm’s wealth by $13.14.

---

Investment Decision Rule

• Positive-NPV investments should be accepted because they increase wealth

• Negative-NPV investments should be rejected because they reduce wealth

Important note:

NPV ≥ 0 is a necessary but not sufficient condition for making an investment decision. Other factors such as risk, liquidity, strategic alignment, and market conditions should also be considered.

---

Unconventional Cash Flows

Not all investments follow a simple pattern of one initial outflow followed by inflows. Many real-world projects have unconventional cash flows, where:

• Cash outflows occur not only at inception

• Additional outflows may appear in future periods (e.g., maintenance costs, reinvestment, environmental cleanup)

An example of unconventional cash flows is:

One major advantage of NPV is that it can handle unconventional cash flow patterns correctly, unlike some other evaluation methods.

---

Present Value of Multiple Cash Flows

The general formula for calculating the present value of multiple future cash flows in Excel is:

This formula forms the foundation of most investment valuation techniques in corporate finance.

so,

Cash flow valuation and NPV are among the most important tools in financial decision-making. By converting future cash flows into today’s values, investors and managers can make rational, value-maximizing decisions that account for time, risk, and opportunity cost.

To amortize a loan

When you borrow money, whether for a home, a car, or a personal project, you typically repay it over time through by making equal, fixed payments. But have you ever wondered exactly how each payment is divided between interest and principal, or how your loan balance decreases year by year?

Amortization refers to the gradual repayment of a loan through a series of fixed payments.
Each payment you make includes two parts:

1. Interest – the cost of borrowing money

2. Principal – the actual amount that reduces your loan balance

Even though the amount paid remains constant, the ratio of principal to interest varies over time.

Assume:

• Loan amount: $100,000

• Term: 5 years

• Interest rate: 9%

• Payment frequency: annual

• Fixed payment each year: $25,709

In the first year, most of your payment goes toward interest. But as time goes on and your remaining balance decreases, you pay less interest and more principal. (You pay less interest each year, more of your fixed payment goes to toward paying down the loan).

The balance, after the last payment, is exactly $0.

Note: This sheet uses modern Excel formulas to make the schedule dynamic. That means the schedule automatically updates itself whenever the loan amount, interest rate, or duration is changed.

The understanding of loan amortization:

• It helps us to understand how much interest you’re really paying.

• It allows us to compare loans and decide whether refinancing is worth it.

• It shows how much equity (ownership) we're building if the loan is tied to an asset, like a house.

Compounding Periods

Compounding refers to earning interest on both the money you originally invest and on the interest that money earns over time. 

Time Value of Money Calculations

We can solve for any one of the following four potential unknowns: future value, present value, the discount rate, or the number of periods. The following lists formulas that can be used in Excel to solve for each input in the time value of money equation.

To Find                               Enter This Formula

Future value                  = FV (rate,nper,pmt,pv)
Present value                = PV (rate,nper,pmt,fv)
Discount rate                = RATE (nper,pmt,pv,fv)
Number of periods    = NPER (rate,pmt,pv,fv)

For example:

If we invest $25,000 at 12 percent, how long until we have $50,000?

The Power of Compound Interest

 Benjamin Franklin once said, “Money makes money, and the money that money makes, makes more money.”

It’s not just a clever line — it’s one of the most powerful truths about building wealth. This is the magic of compound interest.

When you invest, your money starts earning interest. Then that interest earns even more interest. Over time, this creates a beautiful chain reaction — your money grows on its own, faster and faster. 

Think of it like planting a seed.  At first, it’s small. But with time, patience, and consistency, it grows into a tree that bears fruit year after year. You don’t need to start with a lot — you just need to start early and stay consistent. The longer your money has to grow, the more powerful compound interest becomes.

Let your money work for you, not the other way around.

The Foundations of Financial Decisions

When it comes to making smart financial choices — whether you’re investing, saving, or evaluating a project, three key concepts always come into play: 

Future Value (FV), 

Present Value (PV), 

and Net Present Value (NPV)

Let’s break them down in simple terms

🔹 Future Value (FV)

Future Value tells you how much your money today will be worth in the future, assuming it earns interest or grows over time.

Formula:

$$FV=PV\times (1+r{)}^n$$

Where:

• PV = Present Value (today’s money)

• r = interest rate (per period)

• n = number of periods

💡 Example:
If you invest 10,000 $ at an annual rate of 10% for 3 years,

$$FV=10,000\times (1+0.10{)}^3=13,310$$

So, your money grows to 13,310 $ after 3 years.

---

🔹 Present Value (PV)

Present Value tells you how much a future amount of money is worth today, considering the time value of money — the idea that a Toman today is worth more than a Toman tomorrow.

Formula:

$$PV=\frac{FV}{(1+r{)}^{\mathrm{n}}}$$

💡 Example:
If you expect to receive 13,310 $ in 3 years and the discount rate is 10%,

$$PV=\frac{13,310}{(1+0.10{)}^3}=10,000$$

So, the future 13,310 Toman is worth 10,000 $ today.

---

🔹 Net Present Value (NPV)

Net Present Value is used to evaluate investments or projects. It’s the difference between the present value of cash inflows and the present value of cash outflows.

Formula:

$$NPV=\sum \frac{R_t}{(1+r{)}^t}-I$$

Where:

• Rₜ = cash inflow at time t

• r = discount rate

• I = initial investment

💡 Example:
You invest 40,000 $ today and expect 15,000 $ annually for 3 years at a 10% discount rate:

$$NPV=\frac{15,000}{1.1}+\frac{15,000}{{1.1}^2}+\frac{15,000}{{1.1}^3}-40,000=3,735$$

 Since the NPV is positive (3,735), the investment is considered profitable.

If the NPV is negative, the financial consultant should not make to purchase or invest.

---

 Why It Matters

Understanding FV, PV, and NPV helps you:

• Make smarter investment decisions
  
• Compare projects or savings options
  
• Understand the real value of money over time💪

The Relationship Between Growth Rate and EFN

Imagine your business is like a car driving on the road of growth.

The faster you want to go (meaning a higher growth rate), the more fuel you need.
In business terms, that extra fuel is money — and usually, it comes from external financing.

That’s what we call EFN (External Financing Needed) — the amount of extra funding your company needs to support its growth.

• When your growth is slow, your company can grow using its own money (retained earnings, spontaneous liabilities, etc.).

• But when your growth is fast, internal funds usually aren’t enough — so you’ll need to bring in external funds.

---

How Growth Increases EFN

Let’s break it down step by step:

1. Sales increase → You need to produce or buy more goods.

2. To produce more → You need more assets (machines, materials, employees, inventory).

3. More assets → You need more money.

4. But internal funds are limited → So you turn to external financing.

That’s why a higher growth rate often means a higher EFN — because fast growth needs more resources than the company can generate internally.

Let’s say your company’s sales in 2025 are 100 billion $ and you plan to grow next year.

Sales Growth Rate	Approximate EFN	Explanation
5%	1 billion	Low growth → internal funds are enough
20%	5 billion	Moderate growth → some external financing needed
40%	12 billion	High growth → strong need for external financing

 As sales growth increases, EFN also rises.

---

 But Here’s the Caveat

This relationship isn’t perfectly linear. A smart company can manage its finances to reduce EFN even while growing quickly.
Here’s how:

1. Improve profitability → generate more internal funds.

2. Use assets more efficiently → produce more with less investment.

3. Negotiate longer payment terms with suppliers → more spontaneous liabilities.

4. Reduce dividend payout → keep more earnings inside the business.

5. Control growth → avoid expanding faster than your finances can handle.

 Summary

Growth Rate	EFN Level	What It Means
Low	Low EFN	Growth is supported by internal funds
Moderate	Medium EFN	Mix of internal and external financing
High	High EFN	Heavy reliance on external capital

In result:

Fast growth feels exciting — but without enough financial “fuel,” it can be risky.
A truly successful business doesn’t just grow quickly; it grows wisely, balancing expansion with smart EFN management.

Understanding Growth Rates: Internal vs. Sustainable

When a business grows, it’s exciting — but how fast can it grow before running out of money or taking on too much debt? To answer that, we use two key financial growth rates: the Internal Growth Rate (IGR) and the Sustainable Growth Rate (SGR).

Both tell us how fast a company can grow — but they look at growth from slightly different angles.

🌱 What Is a Growth Rate (in general)?

A growth rate simply shows how fast a company’s sales, assets, or earnings are increasing over time — usually year over year.

But there’s a catch:
Every bit of growth needs money — to buy inventory, hire people, or invest in equipment.
So, understanding how much growth a company can afford helps managers plan smarter and avoid financial stress.

That’s where Internal and Sustainable growth rates come in.

---

 1. Internal Growth Rate (IGR)

The Internal Growth Rate is the maximum rate of growth a company can achieve using only internal financing — meaning no external borrowing or new equity.

In other words:

It’s how fast a company can grow using only its retained earnings.

$$\text{Internal Growth Rate}=\frac{ROA\times b}{1- (RO\mathrm{A }\times b)}$$

Where:

• ROA (Return on Assets) = Net Income ÷ Total Assets
  → measures how efficiently the company uses its assets to make profit.

• b (Retention Ratio) = Retained Earnings ÷ Net Income
  → shows what portion of profits is kept in the company (not paid out as dividends).

 Example:

If a company’s ROA = 10% and it retains 60% of its earnings (b = 0.6):

$$IGR=\frac{0.10\times 0.6}{1-(0.10\times 0.6) }= 6.38\mathrm{\%}$$

👌 So the company can grow about 6.4% per year without borrowing or issuing new shares.

---

 2. Sustainable Growth Rate (SGR)

The Sustainable Growth Rate is the maximum growth rate a company can maintain without issuing new equity, while keeping its debt-to-equity ratio constant.

In simple words:

It’s how fast the company can grow using both internal funds and normal borrowing, but without taking on extra financial risk.

$$\text{Sustainable Growth Rate}=\frac{ROE\times b}{1- (RO\mathrm{E }\times b)}$$

Where:

• ROE (Return on Equity) = Net Income ÷ Total Equity
  → shows how efficiently the company uses shareholders’ money.

• b (Retention Ratio) = Retained Earnings ÷ Net Income

---

💦 Bonus:  Dupont Analysis for ROE

We can break ROE into smaller parts using the DuPont formula:

$$ROE=\text{Profit Margin }\times \text{Asset Turnover }\times \text{Financial Leverage}$$

This helps us see how profitability, efficiency, and leverage work together to drive growth.

---

 Example:

If ROE = 15% and the retention ratio b = 0.6:

$$SGR=\frac{0.15\times 0.6}{1-(0.15\times 0.6) }= 9.9\mathrm{\%}$$

👌 The company can grow around 9.9% per year sustainably — using internal funds and its normal level of borrowing.

---

🔗 The Relationship Between IGR and SGR

Concept	Internal Growth Rate (IGR)	Sustainable Growth Rate (SGR)
Financing source	Only internal funds (retained earnings)	Internal funds + normal debt
Debt policy	No borrowing	Constant debt-to-equity ratio
Growth potential	Lower	Higher
Risk level	Lower risk	Moderate risk
Flexibility	Very limited	More flexible

SO,

• IGR < SGR → because adding a reasonable amount of debt allows faster growth.

• If a company grows faster than SGR, it must raise new equity or increase its debt ratio — which could be risky.

• If it grows slower than IGR, it may be underusing its resources.

---

 Final 

Both IGR and SGR help you understand how fast your business can grow safely.
If you push growth beyond these limits, you’ll need external equity or more debt — and that can change your entire financial picture.

🌿 Smart growth isn’t just about going faster — it’s about growing sustainably within your financial capacity.

Understanding EFN (External Financing Needed) in Simple Terms

Have you ever wondered how companies know whether they need to borrow money or attract new investors to grow? That’s where EFN, or External Financing Needed, comes in.

 What is EFN?

EFN tells us how much extra money a company needs from outside sources to support its growth plans. When a company wants to increase sales or expand, it often needs more assets like equipment, inventory, or buildings. If the company’s internal funds (profits and automatic liabilities) aren’t enough, the remaining amount that must come from external sources is called EFN.

In short:

EFN = the extra money a company must raise to grow.

EFN = Assets / Sales × Change in sales - Liabilities / Sales × Change in sales - Profit margin × Projected Sales × (1 - Dividend payout ratio)

---

💥 Example

Let’s take a simple example to make it clear:

Item	Amount (billion $)
Sales (current year)	100
Total assets	80
Liabilities (spontaneous)	30
Net profit	10
Dividend payout ratio	40%

The company plans to increase sales by 25% next year.

Now, step by step:

• New sales (S1) = 100 × 1.25 = 125

• Change in sales (ΔS) = 25

Using the ratios:

• A/S = 80 / 100 = 0.8

• L/S = 30 / 100 = 0.3

• M = 10 / 100 = 0.1

Plug everything into the formula:

EFN = (0.8 × 25) - (0.3 × 25) - (0.1 × 125 × (1 - 0.4)) = 20 - 7.5 - 7.5 = 5

👌 EFN = 5 billion $

That means the company needs 5 billion $ in additional external financing to support its 25% growth goal.

---

💨Understanding better

Understanding EFN helps business owners and managers make smarter growth decisions. 

• If EFN is positive, you’ll need to find external financing. 
• If it’s negative, great — you have extra funds you can reinvest or use to pay off debt.
• If EFN of Zero, the company's internal funds will be sufficient to support its projected growth.

Understanding DuPont Analysis

If you've ever wondered how companies measure their financial profitability or why some companies seem to be more profitable than others, DuPont Analysis is a calculation that can break it down for you. Don't panic if finance is not your specialty—this blog post will explain DuPont Analysis in straightforward language so that you can get a sense of what makes a company profitable.

What is DuPont Analysis?

DuPont Analysis is a magnifying glass for a company's financial health. It takes a key number—Return on Equity (ROE), which represents how good a company is at generating money for shareholders with their own cash—and breaks it into three parts. By doing so, it explains to you why a company is (or isn't) profitable.

Think of a recipe:  ROE is the final meal, and DuPont Analysis tells you what ingredients were utilized to cook it.

The Three Ingredients of DuPont Analysis:

ROE = Profit Margin × Asset Turnover × Financial Leverage

 Profit Margin: How Much of Profit from Sales?

• What it measures: This measures how much profit a firm keeps out of every dollar of sales after subtracting all expenses.
• Formula: Net Income ÷ Sales
• Example: If a company makes $100 in sales and keeps $20 as profit, its profit margin is 20%. A higher margin means the company is good at controlling costs or charging premium prices.

Asset Turnover: How Efficiently Are Assets Used?

• What it measures: This shows how well a company uses its assets (like equipment, inventory, or property) to generate sales.
• Formula: Sales ÷ Total Assets
• Example: If a company has $1,000 in assets and generates $500 in sales, its asset turnover is 0.5. A higher number means the company is generating more sales from its assets.

Financial Leverage: How Much Debt Is Being Used?

• What it measures: This analyzes how much debt a company is using to finance its assets. More debt can boost ROE but adds risk, too.
• Formula: Total Assets ÷ Shareholders’ Equity
• Example: If a company has $1,000 in assets and $400 in equity, its leverage is 2.5. It's borrowing money to pay for some of its assets, and that can amplify returns (or losses)

Why Does DuPont Matter?

DuPont Analysis is like a financial detective. It helps you figure out where a company’s strengths or weaknesses lie. For example:

Low ROE? DuPont can tell you if it's because of unprofitable margins (maybe costs are too high), low asset turnover (maybe assets aren't being put to optimal use), or too much/the least leverage (maybe too much or too little debt).

Comparing companies: You can use DuPont to compare two companies in the same industry and see why one company is more profitable.
Strategic decisions: Managers use it to determine where to cut, such as cutting costs or making better use of assets

Limitations to Keep in Mind

DuPont is not perfect:

• It relies on accurate financial data. If the numbers for an organization are wrong, so is the analysis.
• It doesn’t consider non-financial factors, like market trends or management quality.
• Different industries have different standards, so comparing across sectors can be tricky

How to analysis financial statements and interpret financial ratio?

When deciding where to invest your money, comparing companies can be tricky, especially if they differ in size or industry. Two powerful tools can help: common-size statements and financial ratios. These tools make it easier to understand a company’s financial health and compare it with others. In this post, I’ll break down these concepts using simple language, explain how they work.

What Are Common-Size Statements?

Common-size statements turn financial data into percentages, making it easier to compare companies of different sizes.
Why Use It? It helps you see how a company allocates its resources compared to competitors, regardless of their size.

• common size balance sheets by expressing each item as a percentage of total assets.
• common size income statements by expressing each item as a percentage of total sales.

Frameworks of Financial Reports

💦Assumption on Financial Reporting:

• Fair presentation
• Going concern
• Accrual Basic
• Materiality and aggregation
• No offsetting
• Frequency of reporting
• Consistency
• Comparative Information

💦Fundamental characteristics of useful information:

• Relevance (Information that can affect a decision and encompasses the notion of materiality)
• faithful Representation (complete, natural, free from error)

💦Enhancing characteristics of useful information:

• Comparability
• Verifiability
• Timeliness
• Understandability

Cash flow of the Firm

The cash flow statement explains the change in a company's cash and cash equivalents over a period by categorizing cash flows into three main activities:

1. Operating Cash Flow (CFO): Reflects cash generated from core business operations.
2. Investing Cash Flow (CFI): Reflects cash used for or generated from investments in long-term assets
3. Financing Cash Flow (CFF): Reflects cash transactions with shareholders and creditors.

So,

$$CFO=\text{Net Income}+\text{Non-Cash Items}-\Delta \text{Net Working CapitalNet Income: From the income statement.Non-Cash Items: Typically include depreciation and amortization, as these reduce net income but do not involve cash outflows.Net Working Capital (NWC): Change in current assets (excluding cash) minus current liabilities. An increase in NWC (more inventory or receivables) reduces cash, while a decrease in NWC increases cash.}$$

         CFI= −Cash Paid for Fixed Assets + Cash Received from Sale of Fixed Assets Investing 

• Cash Paid for Fixed Assets: Capital expenditures (purchasing equipment or property).
• Cash Received from Sale of Fixed Assets: Proceeds from selling assets like machinery or buildings.

         CFF=Cash from Issuing Debt/Equity−Cash Paid to Retire Debt/Stock−

                     Cash Dividends Paid−Stock Repurchased

• Includes issuing or repaying debt, issuing or repurchasing stock, and paying dividends.

The net change in cash is:

$$\Delta \text{Cash} = \text{Operating Cash Flow} + \text{Investing Cash Flow} + \text{Financing Cash Flow}$$

---

👉Why Cash Flow Analysis is Popular

We mentioned that cash flow analysis is popular because it’s difficult to manipulate. because:

• Cash-based: Unlike net income, which can be affected by accounting policies (e.g., revenue recognition, depreciation methods), cash flows reflect actual cash movements, making them harder to "spin."
• Transparency: Cash flows provide a clear picture of a company’s liquidity and ability to meet obligations, invest, or return capital to shareholders.
• Decision-making: Investors and creditors rely on cash flows to assess a company’s financial health and sustainability.

---

Free Cash Flow (FCF)

Free Cash Flow represents the cash a company can distribute to creditors and stockholders after funding operations and necessary investments.

$$FCF = \text{Net Income} + \text{Non-Cash Charges} + \text{Interest Expense} \times (1 - \text{Tax Rate}) - \text{Capital Expenditures} - \Delta \text{Working Capital}$$

                         FCF=Net Income+ Non-Cash Charges+ Interest Expense× (1−Tax Rate) −Capital Expenditures−ΔWorking Capital

• Non-Cash Charges: Typically, depreciation and amortization.
• Interest Expense × (1 - Tax Rate): Adjusts for the tax shield on interest, as interest is tax-deductible.
• Capital Expenditures (Capex): Cash spent on acquiring or maintaining fixed assets.
• Change in Working Capital: Increase in NWC reduces FCF, as it ties up cash.

Capital Expenditures (Capex):

$$\text{Capex}=\text{Ending Net Fixed Assets}-\text{Beginning Net Fixed Assets}+\text{Depreciation}$$

• This formula accounts for the change in net fixed assets (after depreciation) and adds back depreciation to capture the actual cash spent on new assets.

Net working capital

Net working capital is the difference between a company’s current assets (like cash, accounts receivable, and inventory) and current liabilities (like bills or loans due within a year). If current assets are greater than current liabilities, net working capital is positive, meaning the company expects to have more cash coming in over the next 12 months than it needs to pay out. For example, if a company has $90,000 in current assets and $50,000 in current liabilities, its net working capital is $40,000, showing it has extra cash to cover short-term obligation. 

The change in net working capital reflects how much more (or less) is invested in these short-term assets compared to short-term debts. In a growing company, this change is usually positive, meaning the company is increasing its current assets (e.g., stocking more inventory or holding more cash) to support growth, like a store adding $10,000 more in inventory and $5,000 in cash while only increasing liabilities by $3,000, resulting in a positive change of $12,000 in net working capital.

Income statements to evaluate companies’ growth, profitability

 The Income Statement: measures performance over a specific period (a year)

Revenue − Expenses = Income

The operations report the firm’s revenues and expenses from principal operations. One number of particular importance is earnings before interest and taxes (EBIT), which summarizes earnings before taxes and financing costs. Among other things, the nonoperating of the income statement includes all financing costs, such as interest expense. Net income is frequently expressed per share of common stock that is, earnings per share.

Earnings per share = Net income / Total share outstanding

Dividend per share = Dividend / Total share outstanding

💦non-cash items: There are several noncash items that are expenses against revenues but do not affect cash flow. Depreciation reflects the accountant’s estimate of the cost of equipment

used up in the production process. Deferred taxes result from differences between accounting income and true taxable income.

Accounting costs usually fit into a classification that distinguishes product costs from period costs. Product costs are the total production costs incurred during a period—raw materials, direct labor, and manufacturing overhead—and are reported on the income statement as cost of goods sold. Both variable and fixed costs are included in product costs. Period costs are costs that are allocated to a time period; they are called selling, general, and administrative expenses.

The balance sheet

Financial analysis is the process of interpreting and evaluating a company’s performance and position in the context of its economic environment, for achieving this goal we have to describe articles of financial statements which helps us to understand better of the target company’s business model.

The Balance Sheet: The balance sheet discloses what an entity owns (assets), what an entity owes (liabilities), and the owners’ interest in the net assets of a company (equity) at a specific point in time. or what the firm owns and how it is financed.

Asset= Liabilities+ Equity

For Analyzing balance sheet first, we know about liquidity, debt versus equity, and value versus cost.

• Liquidity describes how easily and quickly assets can be turned into cash without losing value. Current assets, like cash, accounts receivable (money owed by customers), and inventory (raw materials, work-in-progress, and finished goods), are the most liquid, as they can typically be converted to cash within a year. Fixed assets, such as property, plant, equipment, and intangible assets like trademarks or patents, are less liquid and not usually used to cover short-term expenses like payroll. While having more liquid assets reduces the risk of financial difficulties by making it easier to meet short-term obligations, they often yield lower returns compared to fixed assets, meaning firms may miss out on more profitable investments by focusing too much on liquidity.

• Liabilities are amounts a company owes and must pay in cash within a set time, like a $10,000 bank loan with interest due in a year or a $5,000 bill for supplies due in 30 days. These debts often come with fixed payments, called debt service, and if the company doesn’t pay, creditors (like the bank) can take legal action. Stockholders’ equity is what’s left for the owners after paying all debts, like owning a $100,000 building with a $60,000 mortgage—equity is the $40,000 difference. If the company earns $10,000 in profit and keeps $6,000 instead of paying it as dividends, that $6,000 boosts stockholders’ equity (retained earnings are added). Creditors, like those owed for the loan, get paid before shareholders if the company runs into financial trouble.

• The accounting value of a firm’s assets is frequently referred to as the carrying value or the book value of the assets the book value of the assets. Market value is the price at which willing buyers and sellers would trade the assets. So, when we say the goal of the financial manager is to increase the value of the stock, we usually mean the market value of the stock, not the book value. The distinction between book and market values is important precisely because book values can be so different from market values.

Introduction to Financial Modeling

 Welcome to the thrilling universe of financial modeling! If you ever asked yourself how companies forecast their future, make million-dollar choices, or calculate whether a new project is worth the effort, you're on the right page. Financial modeling is a process of creating a crystal ball for dollars—without it being glass, of course. It is made from spreadsheets, mathematics, and a dash of imagination. Don't worry if you're unfamiliar with this; we'll make it easy to understand, entertaining, and loaded with examples to make you addicted!

Financial planning is another important way to use of financial statements. Most financial planning models use pro forma financial statements, where pro forma means “as a matter of form.” 

In short, a financial model is a spreadsheet-based simulation of a company’s financial performance. you use numbers in a spreadsheet. It’s a tool that helps you predict how much money a business will make, spend, or need based on assumptions about things like sales, costs, or market trends.

Now, why it’s awesome:

• Plan in Advance: Project profits, cash flow, or expenses to prevent surprises.

• Make Decisions: Do you open a new store? A model guides you.
• Impress Others: Show your skills off to employers, investors, or even friends at a finance-themed trivia evening!
• Get to Know Businesses: Models explain what drives a business—imagine an X-ray for profits.

Financial models come in all shapes and sizes, but all of them start with these things:

• Assumptions: Your estimate of what the future will bring.
• Financial Statements: These are like report cards for your business:
• Income Statement: Shows revenue, expenses, and profit
• Balance Sheet: Lists what you have (assets) and what you owe (liabilities)
• Cash Flow Statement: Tracks actual cash inflows and outflows (because profit doesn't always translate into cash in hand!).
• Calculations: Mathematics to forecast results, such as total up expenses or discount future cash flows to present value (more on that in future posts!).
• Outputs: Outputs, such as "You will make $500 profit in a month!" or "This project is a money-loser—Exit!"

The goal of Financial Managements

A definition of the goal is important because it leads to an objective basis for making and evaluating financial decisions. The main goal of financial Managment is to make money and add value for the owners. We can say some possible goals like:

• Survives

• Avoid financial distress and bankruptcy

• Beat the competition

• Maximize sales and market share

• Minimize costs

• Maximize profits

• Maintain steady earnings growth

In fact, we have defined as a study of the relationship between business decision, cash flow and value of the stock in the business. Therefore, a more general way of goal is Maximize the value of the owners’ equity.

Why I'm Starting This Blog: My Motivation and Goals

You might ask, why start a blog in the niche of financial modeling? It is quite personal and practical for me. One of the best ways to expand on my knowledge, I believe, is to give it away. Over the years, I've realized that learning on the job and academic training provide one with a great foundation, but real growth occurs when you take ideas and translate them to actual business scenarios—and then ponder on them. Through blogging, I am committed to improving my working capabilities myself. Each post will force me to explore topics like [e.g., Valuation models, Scenario Analysis, Monte Carlo simulations, or industry case studies], research trends, and experiment with ideas against real data. It's a way to bridge the gap between theory and reality, something I've continuously strived for in my working life. As well as I would like this to be an open forum where I can share my opinions and analysis without restraint. Expect posts on [e.g., "breaking down recent market events with custom models, offering templates for common financial problems, or debating the pros and cons of new software like AI modeling"]. My aspiration is to make complex topics easy to grasp, perhaps with downloadable backup material or step-by-steps, so the reader can apply them on the spot. Ultimately, starting this blog is all about building a community. Are you a new entrant looking to get into the field? A mid-career technical artist, establishing yourself? Even an old pro with different views? I invite you to join in. Comment away, suggest topics, or write your own stories—let's learn together. What's Next? In upcoming posts, I'll be covering [e.g., "a beginner's guide to building your first financial model or analyzing how inflation influences valuation models in 2025"]. If you have something in mind, let me know you'd prefer me to cover, leave a note below. Thanks for reading my first ever post! I'm thrilled to be doing this and look forward to hearing from you. Follow along, subscribe, and let's model our way to better financial understanding
