The working capital formula is current assets − current liabilities. It measures short-term liquidity by comparing assets expected to convert to cash with obligations due in the same short-term window, generally one year or less.
A positive result means current assets exceed current liabilities. The amount needed varies with the business’s industry, size, risk profile, cash-collection timing and, where relevant, inventory turnover.
Working capital formula
Working capital = Total current assets − Total current liabilities
Find both totals on the balance sheet. “Current” generally refers to assets convertible to cash within 12 months and obligations due within 12 months.
Representative current assets
- Cash and cash equivalents: cash and liquid cash-like holdings.
- Accounts receivable: customer amounts not yet paid.
- Inventory: materials, work in progress or finished goods held for sale.
- Marketable securities or short-term investments: investments that can be readily liquidated.
- Prepaid expenses: amounts paid in advance.
Representative current liabilities
- Accounts payable: amounts owed to suppliers.
- Short-term debt: loans and other borrowings due within the short-term period.
- Accrued expenses or liabilities: expenses incurred but not yet paid, including wages or taxes.
- Other short-term obligations: including unearned revenue when classified as current.
Worked example
Balance-sheet inputs
- Total current assets: $300,000
- Total current liabilities: $200,000
Calculation
$300,000 − $200,000 = $100,000 of working capital
Current assets exceed current liabilities by $100,000, so the result is positive. That does not mean the company has $100,000 in cash. Working capital includes items such as receivables, inventory and prepaid expenses alongside cash.
How to read the result
- Positive working capital: Current assets exceed current liabilities. This suggests the company has more short-term resources than short-term obligations.
- Zero working capital: Current assets equal current liabilities. There is no arithmetic cushion in this measure for unexpected costs or changes in cash-flow timing.
- Negative working capital: Current liabilities exceed current assets. It may signal liquidity pressure.
Negative working capital is not automatically a problem. Businesses that collect customer cash rapidly and turn inventory quickly can operate with lower or negative working capital. Longer-cycle, capital-intensive businesses face a different cash requirement. The sign is a starting point for analysis, not a universal pass-fail test.
Keep related formulas separate
Working-capital ratio = current assets ÷ current liabilities. This is a coverage ratio rather than a dollar amount. In the example above, $300,000 ÷ $200,000 = 1.5, or $1.50 of current assets for each $1.00 of current liabilities.
“Net working capital,” or NWC, requires a convention check. Many sources use it interchangeably with the standard current-assets-minus-current-liabilities calculation. Another convention excludes cash from current assets and debt from current liabilities. Label the inputs before comparing companies or periods.
A repeatable workflow
- Pull total current assets and total current liabilities from the balance sheet.
- Subtract current liabilities from current assets.
- Record the dollar result.
- Identify the main drivers, including cash, receivables, inventory, payables, debt and accrued expenses.
- Read the result alongside collection, inventory and supplier-payment timing, and use a consistent NWC convention for trend or peer analysis.
Working capital is a balance-sheet snapshot. Its interpretation depends on the makeup of the reported assets and liabilities and the company’s operating cycle.
Frequently asked questions
What is the difference between working capital and the working-capital ratio?
Working capital is a dollar amount: current assets minus current liabilities. The working-capital ratio is current assets divided by current liabilities, showing current assets reported for each dollar of current liabilities.
Is negative working capital always bad?
No. Negative working capital means current liabilities exceed current assets and may signal liquidity pressure. Businesses that collect customer cash quickly and turn inventory rapidly can operate with low or negative working capital, so the operating cycle matters.
What is net working capital?
Net working capital is often used interchangeably with standard working capital, meaning current assets minus current liabilities. Another convention excludes cash from current assets and debt from current liabilities. State the convention before comparing NWC figures.
How do you calculate the change in working capital?
Calculate working capital for each period using the same definition, then subtract prior-period working capital from current-period working capital.
