The Cash Conversion Cycle: How Fast a Business Turns Sales Into Cash
The cash conversion cycle measures how many days a company ties up cash between paying suppliers and collecting from customers. We explain the three parts and why shorter is stronger.
The days your money is stuck
A business buys inventory, waits to sell it, then waits again to get paid β meanwhile it has already paid its own suppliers. The cash conversion cycle (CCC) measures how many days the company money is tied up in this loop before it comes back as cash. Fewer days means the business funds itself; more days means it needs working capital (or debt) just to keep the lights on.
The three parts
CCC = DIO + DSO β DPO
- DIO β Days Inventory Outstanding: how long inventory sits before it sells (linked to inventory turnover). Shorter is better.
- DSO β Days Sales Outstanding: how long customers take to pay after a sale. Shorter is better.
- DPO β Days Payable Outstanding: how long the company takes to pay its own suppliers. Longer is better here β it means suppliers are financing your operations for free.
So CCC = time cash is locked in inventory and receivables, minus the time you delay paying. The lower the number, the faster your cash comes home.
Why shorter (even negative) is powerful
- Positive CCC: the company must fund the gap β tying up cash it could otherwise invest or return.
- Negative CCC: the holy grail. The company collects from customers before it pays suppliers β customers effectively fund its growth. Great retailers and subscription businesses often run negative CCC, which is a quiet sign of enormous bargaining power and a source of free cash flow.
How to use it
- Compare within an industry and watch the trend. A CCC creeping up can mean inventory is piling (weak demand) or customers are paying slower (credit stress) β an early warning before it shows in earnings.
- Read it alongside the cash flow statement: a profitable company with a ballooning CCC can still run short of cash.
Conclusion
The cash conversion cycle (DIO + DSO β DPO) measures how many days a company money is tied up between paying suppliers and collecting from customers. Shorter is stronger, and a negative cycle β collecting before paying β signals real bargaining power and self-funded growth. Track the trend within an industry as an early warning that profits on paper may not be turning into cash.
