Days Sales Outstanding (DSO) & Collections Calculator for 2026
Calculate your Days Sales Outstanding from accounts receivable and credit sales, then compare it against your collections target.
How Days Sales Outstanding Is Calculated
DSO measures the average number of days it takes to collect payment after a credit sale, using your accounts receivable balance relative to credit sales over a period.
DSO should be calculated using credit sales only, not total sales, since cash sales are collected immediately and would artificially deflate the ratio. A DSO of 30–45 days is generally considered healthy for most B2B businesses, though benchmarks vary by industry.
How to Use the DSO & Collections Calculator
Enter Accounts Receivable
Your outstanding accounts receivable balance at the end of the period.
Enter Total Credit Sales
Total sales made on credit (not cash) during the same period.
Select the period
Choose annual, quarterly, or monthly to match the period your credit sales figure covers.
Set your Target DSO
Usually your standard invoice terms in days, e.g. 30 for Net 30 or 45 for Net 45.
Review your DSO
See your actual DSO, how it compares to your target, and whether your collections process needs attention.
Real-World Scenario Example
"A business has $50,000 in outstanding receivables against $300,000 in annual credit sales, with a Net 45 target."
Inputs
Result
DSO = 60.8 days — about 16 days slower than the 45-day target, signaling a collections process worth reviewing.
Important Disclaimer
This calculator provides an estimate based on the balances and period you enter. DSO benchmarks vary significantly by industry and business model, so compare your result against peers in your own sector rather than a single universal target.
