## 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](https://www.pyalm.com/free-tools/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](https://www.pyalm.com/free-tools/inventory-turnover-calculator).
- Negotiate sensible supplier payment terms.
