Starting values are an editable worked example.

How to use

Calculate average payment days from average accounts payable, cost base and period days.

  1. Enter Average accounts payable.
  2. Enter COGS or purchases base.
  3. Enter Days in period.
  4. Calculate, then review the metric definition and comparison limits.

How it is calculated

DPO = average accounts payable ÷ cost base × period days

Example

Average payables of 75,000 against a 600,000 cost base over 365 days give DPO of about 45.6 days.

Important notes

Credit purchases are preferable when available. Using COGS is a common approximation but may differ from actual purchasing flows.

Frequently asked questions

Should I use COGS or purchases?

Credit purchases are more precise when available. COGS is sometimes used as an approximation when purchase data is unavailable.

Should the inputs use the same period?

Yes. Use figures from the same reporting period and accounting definition so balances and flows remain comparable.

Is the result enough for a decision?

No. The metric summarizes a numerical relationship; compare it with company history, industry context, and accounting or operating policies.
