Days Payable Outstanding Calculator

This days payable outstanding calculator can be used to calculate the average number of days a business is taking to pay its suppliers.

Accounts payable represent amounts owed by a business for goods purchased on account from suppliers. In order to monitor the level of accounts payable it is useful to calculate how many days cost of sales the accounts payable represents. This value is referred to as days payable outstanding (DPO), and shows the average number of days the business is taking to pay for goods purchased on account.

Days payable outstanding is calculated using the days payable outstanding formula, which divides accounts payable, taken from the balance sheet, by the average daily cost of sales, taken from the income statement.
