DPO Optimization Calculator

Find the optimal balance between holding cash and maintaining strong vendor relationships by analyzing your Days Payable Outstanding.

Days Payable Outstanding (DPO) measures how long your organization takes to pay its suppliers. Too low and you lose cash flow advantages; too high and you risk vendor relationships and miss early payment discounts. Our calculator helps you find the sweet spot.

How It Works

Enter your accounts payable balance, cost of goods sold, and payment terms. We calculate your current DPO, compare it to industry benchmarks, and model the cash flow impact of adjusting your payment timing.

How We Calculate

DPO = (Accounts Payable ÷ COGS) × 365. Optimal DPO balances the cost of capital against early payment discount APR. Industry average DPO: 30-45 days.

Frequently Asked Questions

What is a good DPO?

A good DPO depends on your industry and cash flow needs. Generally, 30-45 days is average. Best-in-class companies optimize DPO by paying early when discounts exceed their cost of capital, and paying on time otherwise.

How does DPO affect cash flow?

A higher DPO means you hold cash longer, improving working capital. However, this must be balanced against vendor relationships, early payment discounts, and potential late payment penalties.

Can AP automation help optimize DPO?

Yes. AP automation ensures invoices are processed quickly so you have the option to pay early for discounts or schedule payment at the optimal time. Without automation, slow processing forces late payments regardless of strategy.

What is the DPO formula?

DPO = (Accounts Payable ÷ Cost of Goods Sold) × 365. This tells you the average number of days your company takes to pay suppliers. For example, $500,000 AP ÷ $6,000,000 COGS × 365 = 30.4 days.
