Working Capital Calculator
Calculate net working capital and current ratio from totals or a balance-sheet breakdown. Compare the balance with an optional target.

Working capital formula
Net working capital = current assets − current liabilities. It is a monetary balance at one reporting date. The supplementary current ratio, also called working capital ratio, is current assets ÷ current liabilities, expressed as a multiple rather than a currency amount.
In itemized mode, current assets = cash + net current receivables + inventory + other current assets. Current liabilities = accounts payable + current debt + other current liabilities. Include every current balance exactly once, using the classifications and carrying values in the same entity’s balance sheet.
Target difference = target working capital − calculated working capital. Shortfall to target = max(target difference, 0). Surplus above target = max(−target difference, 0). These are arithmetic comparisons, not a recommendation to borrow.
Verified examples
| Inputs | Net working capital | Current ratio and comparison |
|---|---|---|
| US$250,000 assets; US$150,000 liabilities; US$120,000 target | 250,000 − 150,000 = US$100,000 | 1.6667×; US$20,000 below target |
| €60,000 assets; €90,000 liabilities; target omitted | 60,000 − 90,000 = −€30,000 | 0.6667×; liabilities exceed assets |
| US$50,000 cash + 80,000 receivables + 100,000 inventory + 20,000 other assets; 70,000 payables + 50,000 debt + 30,000 other liabilities | 250,000 − 150,000 = US$100,000 | 1.6667×; same result as total mode |
| US$50,000 assets; zero liabilities | US$50,000 | Ratio undefined: division by zero, not 0× |
What belongs in current assets and liabilities?
Use the current classification from your balance sheet. Current assets commonly include cash, short-term investments, collectible receivables, inventory and prepaid expenses. Place investments or prepayments not listed separately in other current assets. Current liabilities commonly include payables, accruals, taxes payable and the current portion of debt. Place categories not listed separately in other current liabilities. Do not include property, equipment, long-term investments or non-current debt.
Use net receivables after relevant allowances and inventory after relevant write-downs, not an inflated gross estimate. Current classification depends on the operating cycle and applicable accounting framework; this tool does not classify an account for you.
How to interpret positive or negative working capital
A positive result means recorded current assets exceed recorded current liabilities. A negative result means the reverse. Neither is a standalone verdict about business health: collection timing, inventory quality, customer prepayments, supplier terms and the operating model matter. A high ratio can also reflect idle cash or slow-moving inventory. There is no universal ideal target.
The current ratio is undefined when current liabilities are zero, including when both totals are zero. Zero net working capital with equal positive balances produces a current ratio of 1×. Negative working capital is a valid result; negative asset or liability inputs are rejected by this simplified model.
Working capital is not cash runway or the cash cycle
Net working capital is a balance-sheet amount. The cash conversion cycle measures timing in days. Burn rate and runway use cash flows and available cash. Inventory and receivables are not immediately spendable cash, and moving cash into inventory does not automatically change total working capital.
Adding a short-term loan raises cash and current liabilities by the same amount, so it does not by itself improve net working capital. Likewise, paying a current liability from cash reduces both totals equally. A target shortfall therefore must not be interpreted as a loan amount that will automatically fix the balance.
Limits and assumptions
- All active current-balance inputs must be finite, nonnegative amounts. Blank required fields produce an error; enter 0 explicitly where appropriate. Nonzero inputs must have an absolute value of at least 0.000001 currency units; results are displayed to at most six decimal places.
- Each total, including an itemized sum, must be no more than 1 trillion currency units. Optional targets range from −1 trillion to +1 trillion. Comparisons can reach 2 trillion.
- Choose one currency and one reporting date. Currency selection changes formatting only; it does not apply exchange rates.
- This tool calculates conventional net working capital including cash and current debt. It does not calculate a transaction-specific operating or non-cash working capital adjustment.
- No cash-flow forecast, seasonal analysis, account reclassification, tax adjustment, credit decision or accounting opinion is provided.
Educational arithmetic only. Have material reporting, financing or transaction decisions reviewed by a qualified finance or accounting professional.
Frequently asked questions
Is gross working capital the same as net working capital?
No. Gross working capital refers to current assets. Net working capital subtracts current liabilities. This tool shows both current asset total and the net amount.
Why does changing currency not convert my figures?
The selector sets output symbols. Convert source statements consistently before entering them; mixed currencies cannot produce a meaningful net balance.
Should I enter totals and itemized amounts together?
No. Select one method. Hidden inputs are disabled and excluded from the calculation, preventing double counting. Switch methods to reconcile the same balances.
