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.
