The Days Payable Calculator is a simple yet powerful tool that allows you to measure your company’s average payment cycle. By inputting your accounts payable, cost of goods sold (COGS), and time period, you can instantly find out how many days, on average, your business takes to pay its bills.
This tool is especially valuable for:
- Business owners who want to monitor payment efficiency.
- Financial analysts evaluating supplier relationships.
- Investors assessing how a company manages its working capital.

- Enter Cost of Goods Sold (COGS)
- Provide the total cost of goods sold during the period being analyzed.
- Enter Time Period (in Days)
- Typically, businesses use 365 days for an annual calculation, but you can also use 90 days (quarterly) or 30 days (monthly).

Practical Example
Let’s calculate Days Payable Outstanding (DPO) for a sample company:
- Accounts Payable: $50,000
- COGS: $300,000
- Time Period: 365 days
Step 1: Enter 50,000 in Accounts Payable.
Step 2: Enter 300,000 in COGS.
Step 3: Enter 365 as the time period.
Step 4: Click Calculate.
👉 Result:
DPO = (50,000 ÷ 300,000) × 365
DPO = 0.1667 × 365
DPO ≈ 61 days
This means the business takes about 61 days on average to pay its suppliers.
