Cash Conversion Cycle Calculator
Calculate DIO, DSO, DPO, net cash conversion cycle, estimated operating cash tied in a positive cycle, and approximate cycle turns per year. The working-capital timeline draws inventory, collection, supplier-credit offset, and the remaining funding gap.

How to use Cash Conversion Cycle Calculator
- Use average balance-sheet amounts from several dates over the same trailing period.
- Match revenue, COGS, inventory, receivables, and payables to consistent entities and accounting definitions.
- Investigate DIO, DSO, and DPO separately before changing purchasing, credit, collections, or payment policy.
Calculator guide
Understanding Cash Conversion Cycle Calculator
The cash conversion cycle combines inventory days and receivable days, then subtracts payable days. It measures the modeled time operating cash remains committed between paying suppliers and collecting customers.
Calculation method
How the calculation works
Convert average inventory, receivables, and payables into operating days and combine DIO plus DSO minus DPO. Convert average inventory and payables to days using annual cost of goods sold, convert receivables using annual net revenue, then calculate DIO plus DSO minus DPO.
Driver review
Improve the cycle without damaging the business
Working-capital speed must be balanced with service, margin, and relationships.
Worked situations
Practical examples
- $310,000 average inventory against $1.5 million COGS produces about 75.43 DIO.
- $260,000 receivables against $2.4 million revenue produces about 39.54 DSO.
- $180,000 payables create about 43.8 DPO, leaving a cycle near 71.17 days.
Better inputs
Useful tips
- Use monthly averages for seasonal businesses.
- Segment slow inventory and overdue receivables instead of relying only on blended days.
- Avoid extending supplier payments in ways that sacrifice discounts, supply continuity, or trust.
Before relying on the result
Limitations and common mistakes
- The model uses simple annualized ratios and average balances.
- Seasonality, payment distributions, deposits, deferred revenue, taxes, financing, overdue aging, supply terms, and cash-flow timing are simplified or excluded.
- Estimated cash tied uses COGS per day and is not a full working-capital forecast.
Reference
Key terms
- DIO
- Average inventory expressed as days of annual COGS.
- DSO
- Average receivables expressed as days of annual net revenue.
- DPO
- Average payables expressed as days of annual COGS.
- Cash conversion cycle
- DIO plus DSO minus DPO.
Important note
Calculated from the entered values using the displayed accounting method. Reconcile material decisions with source records and applicable accounting policy.
Frequently asked questions
Can the cycle be negative?
Yes when supplier-credit days exceed inventory plus receivable days.
Is a lower cycle always better?
Not if achieved through stockouts, lost discounts, damaged suppliers, or poor customer terms.
Why are revenue and COGS different denominators?
Receivables arise from sales, while inventory and operating payables are generally tied to cost.
Is cash tied the same as working capital?
No. It is a simplified COGS-per-day estimate for a positive modeled cycle.
