Your Cash Conversion Cycle
How This Calculator Works
The Cash Conversion Cycle measures the total time (in days) it takes to turn investments in stock and resources into cash from sales:
DIO = (Inventory / COGS) x 365 — How long stock sits before it is sold.
DSO = (Receivables / Revenue) x 365 — How long customers take to pay.
DPO = (Payables / COGS) x 365 — How long you take to pay suppliers.
A lower CCC is better. A negative CCC means you collect before you pay.

What Is the Cash Conversion Cycle?
The cash conversion cycle (CCC) is the number of days it takes your business to turn money spent on stock and suppliers back into cash from customers. It is the single best measure of how long your working capital is tied up in day-to-day operations – the shorter the cycle, the less cash you need to fund the business.
The Cash Conversion Cycle Formula
CCC = DIO + DSO − DPO
It combines three metrics:
- Days inventory outstanding (DIO) – how long stock sits before it sells.
- Days sales outstanding (DSO), or debtor days – how long customers take to pay you.
- Days payable outstanding (DPO), or creditor days – how long you take to pay suppliers.
A Worked Example
A business with a DIO of 60 days, a DSO of 45 days and a DPO of 30 days has a cash conversion cycle of 60 + 45 − 30 = 75 days. Cash is tied up for about 75 days between paying suppliers and collecting from customers – cash the business must fund from somewhere in the meantime.
What Is a Good Cash Conversion Cycle?
Lower is better, and the right figure varies by sector. Some businesses even run a negative cycle – collecting from customers before they have to pay suppliers – which effectively funds growth for free. For benchmarks, see what is a good cash conversion cycle.
How to Shorten Your Cash Conversion Cycle
- Reduce DIO – hold less stock and sell through it faster.
- Reduce DSO – collect from customers faster.
- Extend DPO – take the supplier terms available to you without damaging relationships.
Frequently Asked Questions
How do you calculate the cash conversion cycle?
Add days inventory outstanding (DIO) to days sales outstanding (DSO), then subtract days payable outstanding (DPO). The calculator above does it once you enter the three figures.
Can the cash conversion cycle be negative?
Yes. A negative CCC means you collect from customers before you pay suppliers – common in subscription and some retail models, and a powerful way to fund growth without external finance.
Why does the cash conversion cycle matter?
It tells you how much working capital your operations tie up. A shorter cycle frees cash; a lengthening one is an early warning that stock, debtors or supplier terms are moving against you.
