Quick answer
Cash conversion cycle (CCC) = days inventory outstanding + days sales outstanding − days payable outstanding. 60 + 45 − 30 gives 75 days.
Enter DIO, DSO and DPO. The calculator returns the number of days cash is tied up in operations.

IEEE-754 double precision; shown to the decimals indicated.
A shorter cycle frees cash sooner.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Days inventory outstanding = 60; Days sales outstanding = 45; Days payable outstanding = 30.
| Result | Value |
|---|---|
| Cash conversion cycle | 75 days |
Example 2
Inputs: Days inventory outstanding = 20; Days sales outstanding = 35; Days payable outstanding = 50.
| Result | Value |
|---|---|
| Cash conversion cycle | 5 days |
The first line is the headline result (cash conversion cycle). IEEE-754 double precision; shown to the decimals indicated.
What the 75 days means
The business spends 60 days selling inventory, waits 45 days to collect, but pays suppliers after 30 days, so cash is out of pocket for 75 days. Shortening the cycle frees working capital.
Negative cycles
The result can be negative, as at retailers that sell goods and collect cash before paying suppliers. A negative cycle is a financing advantage, but it depends on suppliers' terms. Compare against peers, as typical values differ widely by industry.
How the result changes with days inventory outstanding
Holding every other input at the first worked example, this table changes only days inventory outstanding. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Days inventory outstanding | Cash conversion cycle |
|---|---|
| 30 | 45 days |
| 60 | 75 days |
| 120 | 135 days |
| 240 | 255 days |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Days inventory outstanding: entering "-1" shows "Days inventory outstanding must be at least 0." beside that field and no result.
- Days sales outstanding: left empty shows "Enter days sales outstanding." beside that field and no result.

Background: business metrics
Business ratios depend on exactly which costs and revenues you include, so read each page's definition. Two common checks: break-even units = fixed costs ÷ (price − variable cost per unit), so $50,000 of fixed costs with a $10 price and $5 variable cost breaks even at 10,000 units; and net profit margin = net profit ÷ revenue, so $20,000 profit on $100,000 revenue is 20%.
Return on investment ignores time: 20% over five years is far less impressive than 20% in one, so compare returns over the same period.
Assumptions and limitations
- Can be negative
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for days inventory outstanding and days sales outstanding to confirm this.
