What working capital is
Working capital = current assets − current liabilities. It's the short-term money available to run the business after covering near-term obligations. Positive working capital means you can pay your bills; negative is an early warning of a cash crunch. The free Working Capital Calculator gives you the number and the current ratio.
The current ratio
Current ratio = current assets ÷ current liabilities. A ratio between 1.5 and 2.0 is generally healthy. Below 1.0 means liabilities exceed assets in the short term — a liquidity risk. Far above 2.0 can mean cash is sitting idle rather than being put to work.
Why it matters more than profit sometimes
A profitable business can still fail if it runs out of cash. Working capital is the bridge between profit on paper and money in the bank. Slow-paying customers, overstocked inventory, and bunched-up supplier payments all eat into it.
Improving working capital
- Invoice promptly and chase receivables.
- Avoid overstocking — check your inventory turnover.
- Negotiate sensible supplier payment terms.
