How This Calculator Works
Higher DPO keeps cash longer, but paying beyond terms damages supplier trust and credit ratings. Pay within terms, not before.

What Is Days Payable Outstanding (DPO)?
Days payable outstanding (DPO) – known in the UK as creditor days – is the average number of days your business takes to pay its suppliers. A higher number keeps cash in your account for longer, but pushed too far it can strain the supplier relationships you depend on.
The DPO Formula
DPO = (Accounts Payable / Cost of Goods Sold) × 365
For example, a business with £62,000 of trade creditors and £380,000 of annual cost of goods sold has a DPO of (62,000 / 380,000) × 365 = 60 days. On average, it takes 60 days to pay suppliers.
What Is a Good DPO?
Unlike most working-capital metrics, a higher DPO can help your cash flow – up to a point. The aim is to use the full terms your suppliers offer without paying late, which can cost you discounts, goodwill or priority of supply. Balance is everything.
How to Extend Your DPO
Negotiate longer standard terms, schedule payments to the due date rather than early, and centralise approvals so nothing is paid sooner than it needs to be. For more, see how to extend DPO without damaging supplier relationships.
DPO and the Cash Conversion Cycle
DPO is the one part of the cash conversion cycle (CCC = DIO + DSO − DPO) that you want higher: extending it shortens the overall cycle and frees up working capital.
Frequently Asked Questions
How do you calculate days payable outstanding?
Divide accounts payable by cost of goods sold, then multiply by 365. The calculator above does it instantly.
Is DPO the same as creditor days?
Yes. “Creditor days” is the UK term; “days payable outstanding” is the US and textbook name. Both use the same formula.
Can DPO be too high?
Yes. A very high DPO often means you are paying late, which can damage supplier relationships, forfeit early-payment discounts and put your supply at risk.
