The cash conversion cycle: how long your money is locked up
The cash conversion cycle (CCC) measures how many days your cash is tied up between paying for inventory or work and getting paid by customers. Shorter is better: every day of cycle is a day your cash is not yours.
- Three clocks
Days inventory + days receivables − days payables = cash conversion cycle.
- Shorter is better
Every day shaved releases cash you can use elsewhere.
- Dated visibility
On a calendar, the invoice-to-payment gap becomes visible per client.

The formula, step by step
| Component | Formula | Example |
|---|---|---|
| Days inventory outstanding | Inventory ÷ cost of sales × 365 | 30 days |
| Days sales outstanding | Receivables ÷ revenue × 365 | 45 days |
| Days payable outstanding | Payables ÷ cost of sales × 365 | 20 days |
| Cash conversion cycle | DIO + DSO − DPO | 55 days |
What the number means
- 55 days of your cash is tied up in the operating loop.
- Shorten receivables (faster collection) and the cycle shrinks.
- Lengthen payables (slower payment, without hurting terms) and it shrinks too.
- Inventory is the third lever: less dead stock, shorter cycle.
The service-business shortcut
Freelancers and service businesses have no inventory clock, so the cycle collapses to DSO minus DPO. That makes the invoice-to-payment gap the whole game.
For those businesses, the calendar is the tool: each invoice is a dated event, and the running projection shows the real collection gap per client.
Frequently asked questions
What is the cash conversion cycle?
Days inventory outstanding plus days sales outstanding minus days payable outstanding — the days your cash is tied up in the operating loop.
Why is a shorter cash conversion cycle better?
Less of your cash is locked up, so the business needs less borrowing and has more flexibility.
How do I reduce my cash conversion cycle?
Collect faster, pay suppliers on the best allowed terms without damaging them, and reduce slow-moving inventory.
What is a good cash conversion cycle?
For service businesses, near zero or negative is excellent. For retailers, shorter than your supplier terms is the practical target.
