Cash Conversion Cycle Calculator
Days cash is locked in operations.
Calculate cash conversion cycle from days inventory, receivables, and payables to measure working capital efficiency. Free — no signup.
What this tool does
The cash conversion cycle calculator determines how many days working capital is tied up in a business's operations. It combines three metrics: the time inventory sits before sale, the time between sale and cash collection from customers, and the time before paying suppliers. The result shows the gap between when cash leaves your business and when it returns. A shorter cycle means cash flows back faster; a longer one means more capital is locked in day-to-day operations. This calculation assumes linear operations and standard payment terms. The output illustrates operational efficiency in timing, not profitability or absolute cash flow amounts. Businesses with seasonal patterns or irregular payment schedules may see results that don't reflect their actual working capital needs in all periods.
Quick answer: with the default values, the result is 60.0 days (Cash Conversion Cycle). Adjust the values below for your own figures.

The cash conversion cycle (CCC) measures how long cash is tied up in operations. Days Inventory Outstanding + Days Sales Outstanding - Days Payable Outstanding. The shorter the cycle, the faster cash moves through the business. Negative cycles (common in supermarkets and fast-food) mean suppliers are financing operations - a remarkable working capital advantage.
45 days inventory + 45 days receivables - 30 days payables = 60-day CCC. For every 1 of daily revenue, 60 days of cash sit locked in working capital. On 10M annual revenue (27k/day), that's 1.64M tied up. Cut inventory or receivables by 15 days and you free 411k cash.
The three components pull in different directions. Lower inventory turns risk stockouts; faster receivables collection risks pushing away customers who value credit terms; slower supplier payments risks losing early-pay discounts and damaging relationships. Optimising CCC is a balancing act, not a single-lever push.
Run it with sensible defaults
Using days inventory of 45, days receivable of 45, days payable of 30, the calculation works out to 60.0 days. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Days Inventory (DIO), Days Receivable (DSO), and Days Payable (DPO) — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
How the math works
CCC = days inventory + days receivables - days payables. Measured in days.
Reading a low result
A disappointing result is information, not a judgement. The input that dragged the figure down most is usually where a single change has the largest effect, since depth on the worst input tends to move the result more than spreading effort across every input at once.
What this doesn't capture
The result reflects only the inputs you provide and the assumptions built into the formula. It is a simplified model rather than a complete picture, and factors specific to your situation may matter just as much.
45 DIO + 45 DSO - 30 DPO = 60.0 days.
Inputs
| Days Inventory | 45.0 days |
|---|---|
| Days Receivable | 45.0 days |
| Days Payable | 30.0 days |
| Cycle Health | Normal |

Sources & Methodology
Methodology
The calculator computes the cash conversion cycle by adding days inventory outstanding (the average number of days inventory sits before sale) to days sales outstanding (the average number of days to collect payment from customers), then subtracting days payable outstanding (the average number of days the business takes to pay suppliers). The result represents the number of days cash is tied up in operating activities. The model assumes constant operational ratios across the measurement period and treats each component as a stable average. It does not account for seasonal variation, working capital management changes, transaction costs, or differences in payment terms by customer or supplier type. The metric serves as a snapshot of operational efficiency and cash flow timing.
