What this calculator does

DPO measures how long a business takes to pay suppliers. Combined with DSO and DIO it gives the cash conversion cycle — how long cash is tied up in operations.

Formula and method

DPO = (average payables ÷ COGS) × days; Cash conversion cycle = DSO + DIO − DPO

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Average accounts payable: 40000 (any currency)
  • Cost of goods sold for the period: 292000 (any currency)
  • Days in period: 365
  • DSO (optional, for cash conversion cycle): 50
  • DIO (optional, for cash conversion cycle): 60

Results

  • Days payable outstanding: 50 days
  • Payables turnover: 7.3 ×
  • Cash conversion cycle (DSO + DIO − DPO): 60 days

How to read the results

A shorter or negative cash conversion cycle means operations need less financing.

Assumptions and limitations

  • Stretching payables too far can damage supplier relationships.

Financial results are estimates based on the inputs and assumptions shown. They are not financial advice; confirm figures with your lender, provider or a qualified adviser before making decisions.

Questions

Can the cash conversion cycle be negative?

Yes — when customers pay before suppliers must be paid, as in some retail models.
