DPO is the average number of days a company takes to pay its suppliers.
What it is
Days Payable Outstanding (DPO) measures how long, on average, a firm waits before paying invoices owed to its suppliers and vendors for goods bought on credit. It is calculated by dividing accounts payable by cost of goods sold (COGS) and multiplying by the number of days in the period (365 for a full year). A higher DPO means the company is holding onto its cash longer before settling supplier bills.
Why it matters
A higher DPO is effectively free, interest-free financing from suppliers: cash stays in the business longer, improving working capital and free cash flow. The common pitfall is reading "higher is always better" too literally. Stretching payment terms too far can anger suppliers, cost early-payment discounts, invite worse pricing, or signal liquidity stress to creditors. A sudden DPO spike can mean the company is conserving cash because it is short of it, not because it negotiated hard.
How it's calculated
Divide accounts payable (from the balance sheet) by cost of goods sold (from the income statement), then multiply by the number of days in the period, typically 365 for an annual figure or 90 for a quarter. Many analysts use average accounts payable, the average of beginning and ending balances, to smooth out period-end timing. The result is expressed in days.

Cross-border note. DPO is calculated identically for Canadian and U.S. issuers since both IFRS (used by most Canadian filers) and U.S. GAAP report accounts payable and COGS on the same statements. When comparing a TSX-listed company against a U.S. peer, confirm both report COGS the same way, as some firms bundle costs into operating expenses, which can distort the comparison.
FAQ
Is a high DPO always a good sign?
Not necessarily. A high DPO can reflect strong supplier negotiating power and smart cash management, but it can also mean the company is delaying payments because it lacks cash. Check whether the increase is gradual and stable or a sudden spike, and read it alongside the current ratio and free cash flow.
How does DPO fit into the cash conversion cycle?
DPO is the subtracted term: Cash Conversion Cycle = Days Inventory Outstanding + Days Sales Outstanding − DPO. Because suppliers are effectively financing part of the operating cycle, a higher DPO shortens the CCC, meaning the company ties up less of its own cash.
Check your understanding
Two retailers each have $50M in accounts payable, but Retailer A reports $200M in COGS while Retailer B reports $400M. Using DPO = (AP ÷ COGS) × 365, which statement is correct?
Retailer A's DPO is (50 ÷ 200) × 365 ≈ 91 days versus Retailer B's (50 ÷ 400) × 365 ≈ 46 days; with equal payables, the firm with lower COGS takes longer to pay relative to what it buys.
