📅 Average Collection Period Calculator
Calculate how many days on average it takes your business to collect accounts receivable from customers.
Days Sales Outstanding (DSO)
If you offer Net 30 terms but your ACP is 52 days, customers are paying late. ACP under 45 days is generally healthy. Compare to your payment terms: if ACP > terms, collections need attention.
What Average Collection Period Reveals About Your Business
Average Collection Period (ACP) = Accounts Receivable ÷ (Annual Credit Sales ÷ 365). Also known as Days Sales Outstanding (DSO), it tells you how long your cash is tied up in receivables. A business with 45-day ACP is effectively extending an interest-free loan to customers for 45 days. The faster you collect, the better your working capital position and the less you need to borrow to fund operations.
Industry Benchmarks for ACP
Manufacturing: 35–50 days. Retail/wholesale: 20–40 days. Professional services: 30–60 days. Construction: 45–70 days. Healthcare: 40–55 days. Software/SaaS: 30–45 days. Compare your ACP to your stated payment terms — if you offer Net 30 but your ACP is 55, you have a collections problem. Benchmark against peers, not universal standards.

Generally, ACP should not significantly exceed your stated credit terms. If you offer Net 30 payment terms, an ACP of 30–38 days is healthy (some customers pay early). Above 50 days on Net 30 terms indicates systemic late payment issues. Below your terms indicates early payment incentives are working.
Send invoices immediately upon delivery, offer early payment discounts (2/10 Net 30 — 2% discount if paid within 10 days), automate payment reminders at 30, 45, and 60 days past due, require deposits for large or new customers, and review credit limits for chronic late payers.
They are calculated identically and measure the same thing. DSO (Days Sales Outstanding) is the more common term in finance and accounting software; ACP is used more in academic and textbook contexts. Both equal Accounts Receivable ÷ Average Daily Sales.
