Working Capital Calculator: Measure Short-Term Financial Health
Working capital answers a simple but critical question: does a business have enough short-term assets to cover its short-term obligations? This calculator breaks down current assets and current liabilities into their common components, then computes working capital alongside the current ratio and quick ratio for a fuller liquidity picture.
Current Ratio = Current Assets ÷ Current Liabilities. Quick Ratio = (Current Assets − Inventory) ÷ Current Liabilities.
Working Capital vs. Current Ratio
Working capital is a dollar amount — it tells you the absolute cushion a business has. The current ratio is that same relationship expressed as a proportion, which makes it easier to compare liquidity across businesses of very different sizes. A $50,000 working capital cushion means something very different for a small shop than for a large manufacturer.
Why the Quick Ratio Is Stricter
Inventory is a current asset, but it isn't cash — it has to be sold first, and that can take weeks or months depending on the business. The quick ratio removes inventory from the current assets calculation, showing what's available to cover liabilities using only cash, receivables, and other near-cash assets.
Reading the Ratio Thresholds
A current ratio under 1.0 means current liabilities exceed current assets — a red flag for short-term liquidity. Between 1.0 and 1.5 is workable but tight, with little cushion for unexpected expenses. Above 1.5 (and up to roughly 3.0) generally signals healthy liquidity without excess idle assets.

Frequently Asked Questions
What is working capital?
Working capital is Current Assets minus Current Liabilities — the money a business has available to cover its short-term obligations and day-to-day operations.
What counts as a 'current' asset or liability?
Current means expected to be converted to cash or paid off within 12 months. Current assets include cash, receivables, and inventory; current liabilities include accounts payable and short-term debt.
What's a healthy current ratio?
A current ratio (current assets ÷ current liabilities) of 1.5 to 3 is generally considered healthy. Below 1.0 means liabilities exceed assets, a liquidity warning sign. Above 3 can sometimes indicate assets aren't being used efficiently.
Why does the quick ratio exclude inventory?
Inventory can take time to sell and convert to cash, so the quick ratio (also called the 'acid-test' ratio) strips it out to show a stricter view of immediate liquidity — assets that can be converted to cash quickly.
Can working capital be negative?
Yes. Negative working capital means current liabilities exceed current assets, which can signal a cash flow problem — though some fast-inventory-turnover businesses (like grocery retailers) can operate with negative working capital by design.
Is this the same as free cash flow?
No. Working capital is a balance-sheet snapshot of short-term liquidity at a point in time. Free cash flow measures actual cash generated over a period, after capital expenditures.
