Days Payable Outstanding Calculator
Days payable outstanding estimates the number of days a business takes, on average, to pay trade suppliers relative to cost of goods sold over the same period.
How to use this calculator
- Enter average accounts payable, cost of goods sold for the same period, and period length in days.
- Check the labels and units before applying the result to a real task.
- Change one input at a time when comparing scenarios.
Formula and method
DPO = average accounts payable ÷ cost of goods sold × days in period
- DPO = average accounts payable ÷ cost of goods sold × days in period
- Accounting classifications and supplier terms vary. A high DPO is not automatically desirable and can strain supplier relationships if it reflects late payment.
Worked examples
Worked example
Average accounts payable of 3,000 and period COGS of 100,000 across 365 days.
DPO = 3,000 ÷ 100,000 × 365 ≈ 10.95 days.
DPO = 3,000 ÷ 100,000 × 365 ≈ 10.95 days.

Frequently asked questions
What does DPO measure?
It approximates how many days of the period’s cost of goods sold are represented by average trade payables.
Is higher DPO always better?
No. Cash management must be balanced with contractual due dates, discounts, supply continuity and vendor relationships.
Should I use total operating expenses?
The standard form commonly uses cost of goods sold. Use an internally consistent accounting definition and compare periods on the same basis.
