Plain definition
Working capital requirement is the amount of funding the operating cycle needs because cash is tied up in inventory, customer credit, and other operating current assets before supplier credit and operating accruals offset part of that need. It is often estimated using net operating working capital, but the term is forward-looking when management asks how much additional funding a plan will require.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
A distributor currently has net operating working capital. Management plans to increase stock for a new contract and give the customer 60-day terms. The forecast operating balance-sheet schedule shows receivables, inventory, and other operating assets less payables and accruals will reach . The plan therefore adds to the working capital requirement.
Before accepting the contract, the chief executive asks where the will come from and in which weeks it will be needed. The team schedules stock deposits and expected collections, then decides whether to use available cash, negotiate supplier credit, request a customer deposit, or arrange funding.
| Forecast net operating working capital | |
|---|---|
| Current net operating working capital | |
| Incremental working capital requirement |
Why it matters
A growth plan can fail even when its margin is attractive if it consumes cash before it collects it. Measuring the incremental requirement prevents management from approving revenue without also approving the cash and timing needed to deliver it.
Practical consequence
Build a forward operating schedule for material receivables, inventory, payables, and accruals rather than applying one percentage to sales. State the sales terms, stock lead time, purchase deposit, supplier credit, and expected collection date. Compare the forecast requirement with committed cash and facilities in a dated cash forecast. Rework the commercial terms or funding plan if the projected low point breaches the company’s cash floor.
