About this calculator
Days payable outstanding is DPO = (accounts payable / COGS) × number of days in the period — it converts an outstanding supplier balance into an average number of days the company takes to actually pay its bills.
A higher DPO means a company is holding onto cash longer and effectively using suppliers as a source of short-term, interest-free financing — good for cash flow up to a point, but too high a number can signal strained supplier relationships or genuine payment trouble. Finance teams and analysts track it alongside days sales outstanding and days inventory outstanding as part of the full cash conversion cycle.
