DPO Calculator: Are You Paying Suppliers Too Early?

Most companies pay suppliers 5 to 15 days before the due date without deciding to. This calculator finds your Terms Gap and tells you whether to take or skip early payment discounts when they’re offered.

DPO Calculator

Find The Terms Gap: how many days early you're paying suppliers and what it costs you.

days
Your average agreed payment terms with suppliers (e.g. net-45).
e.g. 2% for 2/10 net-30. Leave blank if no discount.

Deep dive: Days Payable Outstanding - Are You Paying Too Fast?

How to Read Your Results

Positive Terms Gap?

You’re paying before you need to. For a EUR 10M COGS business, a 14-day Terms Gap is EUR 384K returned to suppliers ahead of schedule every year. That’s recoverable without renegotiating a single contract.

Negative Terms Gap?

You’re paying after contracted terms. Late payment damages supplier relationships, can trigger penalty clauses, and may close off early payment discount offers in future.

Discount verdict shown?

The calculator compares the annualized return of taking the discount against your cost of capital. A 2/10 net-30 offer annualizes to roughly 37% — that beats almost any cost of capital. A 0.5% discount for 10 days early annualizes to around 18%, which is more marginal.

Key Insight: Closing the Terms Gap requires no negotiation with customers, no inventory changes, and no new financing. It’s the only working capital improvement that lives entirely inside your AP process.
