What is Days Payable Outstanding?

Days Payable Outstanding (DPO) measures the average number of days a company takes to pay its suppliers. A higher DPO means the business is using supplier credit as a cheap source of working capital. When DPO is elevated relative to industry peers, it can indicate either strong negotiating power (Amazon, Walmart) or stretched cash flow (warning sign in distressed firms).

Formula

DPO = (Accounts Payable / COGS) × 365

Why DPO Matters

Companies with high DPO effectively use their suppliers as an interest-free credit line. Walmart and Costco famously run DPO above 40 days, funding inventory turn with vendor terms. By contrast, smaller competitors with weaker negotiating power pay in 15-30 days and must finance the gap with bank debt.

For value investors, the trend matters more than the level. A steadily rising DPO often signals improving supplier leverage; a sudden spike combined with falling inventory turnover can foreshadow distress.

Frequently Asked Questions

What is Days Payable Outstanding?+

DPO is the average number of days a company waits before paying its trade creditors. It is calculated as (Accounts Payable / Cost of Goods Sold) × 365. A DPO of 60 means the company on average pays suppliers 60 days after receiving inventory or services.

Is a higher DPO better?+

In moderation, yes. A higher DPO means the company is financing more of its operations with interest-free supplier credit. However, if DPO spikes well above industry norms, suppliers may tighten terms or demand cash on delivery, which can create supply-chain risk. Look at the trend rather than the absolute level.

How does DPO fit into the Cash Conversion Cycle?+

DPO is the third component of the Cash Conversion Cycle: CCC = DSO + DIO - DPO. A longer DPO reduces the cash conversion cycle because the company holds onto cash for longer before paying suppliers. Capital-efficient businesses often have CCC < 0 by stretching DPO and compressing DSO.
