Cash Conversion Cycle Calculator

June 30, 2026 • By the Investor Sam Editorial Team • Reviewed by Berly Sam Varghese, Editor
The cash conversion cycle measures how long your money is locked up in the business before it comes back as cash. It combines the days your inventory sits, the days customers take to pay you, and the days you take to pay suppliers. A shorter cycle means cash returns faster and you need less working capital to grow. This calculator computes the cycle and the underlying operating cycle so you can spot where cash is trapped.

Example: Days inventory outstanding: 50 days · Days sales outstanding (receivables): 40 days · Days payable outstanding: 30 days

Cash conversion cycle (days)60
Operating cycle (days)90

Worked example

If inventory sits 50 days and customers pay in 40 days, your operating cycle is 90 days. But you take 30 days to pay suppliers, which effectively finances part of that. The cash conversion cycle is 50 + 40 minus 30 = 60 days, meaning your cash is tied up for two months per turn. Shortening any of the three levers frees cash you would otherwise have to borrow or raise.

Frequently asked questions

What does a negative cash conversion cycle mean?

It means you collect from customers before you pay suppliers, so your suppliers effectively fund your operations. Some large retailers and subscription businesses run negative cycles, a powerful position that fuels growth with little working capital.

How do I shorten my cycle?

Turn inventory faster, collect receivables sooner with better terms or deposits, and negotiate longer payment terms with suppliers. Improving any of the three lowers the cycle and frees up cash.

Why include days payable?

Because the time you take to pay suppliers is free financing that offsets the cash tied up in inventory and receivables. Subtracting it gives the true number of days your own cash is committed.

Where do I get these day figures?

Days inventory is inventory divided by daily cost of goods sold; days receivable is receivables divided by daily sales; days payable is payables divided by daily cost of goods sold. Your accounting software can report all three.
