What Working Capital Means
Working capital is the money a business has available to fund its day-to-day operations. It is the difference between what the business owns in the short term and what it owes in the short term.
Positive working capital means current assets cover current liabilities. Negative working capital means the business may struggle to pay suppliers and meet short-term obligations without extra funding.
Working Capital Formula
Working Capital = Current Assets − Current Liabilities
Current assets are cash and other assets expected to convert to cash within a year. Current liabilities are obligations due within the same period.
Net Working Capital
Net working capital is simply current assets minus current liabilities. It is usually the same figure as working capital and shows the absolute buffer available to run operations.
A rising net working capital figure can mean the business is building cash or inventory. A falling figure can signal tightening liquidity, even if sales are growing.
Working Capital Ratio
Working Capital Ratio = Current Assets ÷ Current Liabilities
The ratio puts the same numbers in relative terms. A ratio of 1.5 means the business has £1.50 of short-term assets for every £1.00 of short-term liabilities.
Ratios below 1.0 suggest potential liquidity pressure. Very high ratios may mean cash is sitting idle or inventory is growing too fast.
Worked Example
A business has £45,000 in current assets and £28,000 in current liabilities. Its working capital and ratio are calculated as follows.
Net Working Capital = £45,000 − £28,000 = £17,000
Working Capital Ratio = £45,000 ÷ £28,000 = 1.61
Use Cases
Liquidity Health Check
Use net working capital and the ratio to see whether the business can cover short-term bills without borrowing.
Supplier Negotiations
A strong ratio gives confidence to negotiate better payment terms, while a weak ratio may prompt earlier conversations.
Growth Planning
Fast growth can drain working capital through receivables and inventory. Track the ratio before scaling.
Lender & Investor Reporting
Banks and investors often ask for the current ratio. A stable or improving figure supports credit applications.
