Working capital

The money tied up between paying for operations and collecting from customers.

Accounting working capital is current assets less current liabilities. Operating analysis often narrows the focus to inventories and receivables less operating payables. The cash conversion cycle describes how long cash is tied up between paying suppliers and collecting customer receipts.

Cash conversion cycle = inventory days + receivable days − payable days

Why it matters

A profitable business can consume cash as it grows. It may need to buy stock and pay wages before the related invoice is collected. Conversely, customer prepayments and supplier credit can fund part of an operating cycle.

A worked illustration

Illustrative: goods sit for 40 days, customers pay 30 days after sale, and suppliers are paid after 25 days. The cycle is 45 days. Reducing inventory by 10 days releases cash only if service levels and purchasing economics remain acceptable.

Where the idea can mislead

Negative operating working capital can reflect a strong payment model or overdue bills. Current ratios do not replace a dated cash forecast. Financial institutions require different liquidity analysis.
