Working Capital Calculator
Measure the absolute cushion between a firm’s short-term assets and the obligations falling due in the next twelve months. Computes working capital alongside the current ratio and the working-capital ratio.

A modestly positive working-capital figure is the normal operating range for most mature businesses: assets due within twelve months at least cover the matching liabilities, with enough slack to absorb routine timing differences in receivables, payables, and inventory. Compare against sector peers (retailers and supermarkets often run negative because inventory turns very fast; industrials and pharma typically run a chunky positive) and watch the trend across periods.
How to use this calculator
Pull two totals from the most recent balance sheet: total current assets (cash and equivalents, short-term investments, trade receivables, inventory, prepaid expenses, and anything else classified as realisable within twelve months) and total current liabilities (accounts payable, accrued expenses, short-term borrowings, the current portion of long-term debt, deferred revenue due within twelve months). The calculator subtracts the second from the first to get working capital in currency, divides the first by the second to give the current ratio, and divides working capital by current assets to show the working-capital ratio. Defaults use Microsoft’s fiscal 2023 10-K ($184.257B current assets, $104.149B current liabilities) producing working capital of $80.108B.
How the calculation works
Working capital is the absolute-currency companion to the current ratio: where the ratio expresses the comparison as a multiple, working capital expresses it as the cash-equivalent cushion the firm holds between short-term assets and short-term obligations. A positive figure means current assets cover current liabilities outright; a negative figure means the firm relies on rolling supplier credit, fast inventory turnover, or fresh finance to bridge the gap. The metric is most useful when paired with the current ratio (multiple of cover), the quick ratio (which strips inventory out of the numerator), and the operating cash flow trend — because working capital uses balance-sheet values rather than projected cash flows and can flatter firms with slow-moving stock or stretched receivables.
Worked example
Microsoft’s fiscal 2023 (ending Jun 30, 2023) 10-K balance sheet reported total current assets of $184.257B (cash and equivalents $34.704B, short-term investments $76.558B, accounts receivable $48.688B, inventories $2.500B, other current assets $21.807B) and total current liabilities of $104.149B (accounts payable $18.095B, current portion of long-term debt $5.247B, accrued compensation $11.009B, short-term income taxes $4.152B, short-term unearned revenue $50.901B, other current liabilities $14.745B). Working capital = 184.257 − 104.149 = $80.108B. Current ratio = 184.257 / 104.149 = 1.769. Working-capital ratio = 80.108 / 184.257 = 43.5%. The chunky positive cushion is typical of mature high-margin software firms with large deferred-revenue balances and net-cash balance sheets.
Frequently asked questions
What counts as a "good" working capital figure?
There is no universal threshold — the right level is heavily sector-dependent and scale-dependent. Software, branded consumer goods, and pharma typically run substantial positive working capital because they carry meaningful inventory, receivables, and accrued R&D commitments. Industrials and chemicals cluster positive but smaller. Supermarkets, discount retailers, and quick-service restaurants frequently run negative working capital — sometimes deeply so — because inventory turns extremely fast and supplier credit is generous. Always compare against sector peers and against the firm’s own multi-year trend. A working-capital figure of zero is excellent for a grocer and worrying for a pharma firm.
How is working capital different from the current ratio?
They describe the same liquidity position from different angles. Working capital is current assets minus current liabilities — an absolute figure in currency units, so you can read the cushion directly against revenue, planned investment, or financing needs. The current ratio expresses the same comparison as a multiple of cover (current assets divided by current liabilities). Larger firms often quote working capital in absolute terms because it shows the cash-equivalent buffer; comparison across firms of different sizes is easier using the ratio. Use both — the calculator returns each from the same inputs.
Can working capital be too high?
Yes — very high working capital relative to revenue or assets (often visible as a working-capital ratio above ~50% in non-financial businesses, though the threshold varies by sector) can signal under-utilised capital rather than strength. Common drivers are excess cash that should be returned to shareholders, slow-moving or obsolescent inventory inflating the assets line, or stretched receivables suggesting collection problems. A working-capital balance that has climbed sharply over recent periods is worth investigating: read the cash, inventory, and receivables movements separately, and pair the figure with inventory turnover and days sales outstanding before concluding the trend is healthy.
What does negative working capital actually mean?
Negative working capital — current liabilities exceeding current assets, equivalent to a current ratio below 1.0 — means the firm’s short-term assets do not, on the balance-sheet date, cover the obligations due within twelve months. In capital-intensive or distressed businesses, that is a red flag. In high-turnover retail and food-service models, it is normal and often efficient: supermarkets collect cash from customers immediately while paying suppliers on 30–60 day terms, so the cash cycle naturally produces negative working capital without solvency strain. Read the figure against the business model before treating it as a warning. Apple’s FY2023 10-K reported negative working capital of −$1.742B despite a fortress balance sheet, because its supply-chain payable terms run longer than its receivables cycle.
How is working capital used in valuation and forecasting?
In discounted-cash-flow modelling, the year-on-year change in net working capital is subtracted from operating cash flow to arrive at free cash flow: growth firms typically need to fund a rising working-capital balance as receivables and inventory expand, which is a real cash outflow even though it does not pass through the income statement. Analysts often quote working capital as a percentage of revenue (net-working-capital margin) to forecast cash needs from revenue growth. The calculator’s working-capital ratio (working capital over current assets) is a related but different lens — it measures how much of the firm’s short-term asset base is unencumbered by short-term claims.
Where on the balance sheet do I find current assets and current liabilities?
Under both IFRS (IAS 1) and US GAAP (ASC 210), the balance sheet groups assets and liabilities into current and non-current classes. Current assets are listed first, with cash and equivalents at the top, then short-term investments, receivables, inventories, and other current assets — every line expected to be realised within twelve months or the operating cycle, whichever is longer. Current liabilities follow the same logic on the other side: payables, accrued expenses, short-term borrowings, the current portion of long-term debt, and deferred revenue due within twelve months. The totals for each section are normally shown explicitly; if not, sum the line items between the section header and the first non-current line.
