How it is calculated
Working capital need = annual cost of goods sold ÷ 365 × cash conversion cycle. The first part is the cost of one day of operations, the second is how many days cash is tied up in the operating cycle; together they give the amount the business needs to keep in circulation (its own cash or a credit line) so the buy → sell → get paid cycle doesn't stall.
This calculation is the forward-looking, cash version of the same cycle that the Cash Conversion Cycle calculator measures in days and the Net Working Capital calculator measures as of a reporting date. The goal here is to estimate the cash need ahead of time — for example, when planning sales growth.
The need grows in proportion to business scale at the same cycle length: doubling cost of goods sold (i.e., doubling volume) at an unchanged CCC also doubles the working capital need. That's a major reason fast-growing companies routinely run short of cash even while profitable — growth absorbs capital into the operating cycle faster than profit accumulates.
