Working capital is one of the most fundamental concepts in business finance — yet it's frequently overlooked until a crisis hits. This guide explains what it is, why it matters, and what to do when you need more of it.
The Definition
Working Capital = Current Assets − Current Liabilities
Current assets include cash, accounts receivable, and inventory. Current liabilities include accounts payable, short-term loans, and accrued expenses. The result represents liquid resources available to run your business day to day.
Why It Matters
Even a profitable business can fail if it runs out of working capital. A cash flow crisis — where a business is profitable on paper but insolvent in practice — is one of the leading causes of small business failure. Cash tied up in inventory or receivables can't pay rent or payroll.
Warning Signs
- Frequently delaying supplier payments
- Turning down orders you can't finance
- Dipping into personal funds for business expenses
- Payroll coming dangerously close to being missed
- More than 60 days of outstanding receivables
How to Improve Working Capital
Shorten your collection cycle: Invoice immediately after delivery and follow up aggressively at 7, 14, and 30 days.
Negotiate better supplier terms: Net-45 or Net-60 terms with suppliers effectively give you an interest-free short-term facility.
Reduce excess inventory: Every dollar in unsold inventory is cash not available for operations.
Access a business line of credit: A revolving line provides a working capital buffer without committing to a long-term loan.
The Current Ratio
Current assets ÷ current liabilities. A ratio above 1.5 is healthy for most small businesses. Monitor it monthly and act before it drops below 1.2.
