Days Payable Outstanding Calculation
The Days Payable Outstanding (DPO) metric evaluates how many days, on average, your company takes to pay your creditors. A higher DPO can mean your company delays payments to use funds for short-term investments and boost cash flow. Or, it can show that resource funds might not be used efficiently.
NetSuite calculates the monthly Days Payable Outstanding using the following formula:
| Days Payable Outstanding (DPO) | = | Average Days Open of Fully Paid Bills for the Month | 
Similar to the Days Sales Outstanding calculation, if Company B has two vendor bills settled for the month of May:
| Vendor Bills | Transaction Date | Date Closed | Number of Days Open | 
|---|---|---|---|
| Vendor Bill A | May 5, 2024 | May 31, 2024 | 26 | 
| Vendor Bill B | May 15, 2024 | May 31, 2024 | 16 | 
The DPO is calculated for May 2024 as:
| Days Payable Outstanding (DPO) | = | (26+16)/ 2 | 
| 
 | = | 42/ 2 | 
| 
 | = | 21 |
