How to calculate accounts payable days
Accounts payable days (also called Days Payable Outstanding) measures the average number of days a company takes to pay its suppliers — a working capital metric used to evaluate payment practices and cash flow management.
How the calculation works
AP days = (Average accounts payable ÷ Annual purchases) × 365.
Example
$180,000 average accounts payable against $2,190,000 in annual purchases: AP days = (180,000 ÷ 2,190,000) × 365 = 30 days.

Pro Tips for Accounts Payable Days
- A longer AP days figure can indicate favorable payment terms and better cash retention, but excessively long can strain supplier relationships.
- Compare AP days to your actual negotiated payment terms (e.g., Net 30, Net 60) to see if you're paying on time, early, or consistently late.
Common Accounts Payable Days Mistakes to Avoid
- Comparing AP days across companies of very different sizes or industries without context, since typical payment terms vary significantly by industry.
