Days Sales Outstanding (DSO) Calculator
Days Sales Outstanding (DSO) Calculator
DSO translates the accounts receivable turnover ratio into an intuitive "days" figure — instead of "how many times a year," it tells you "how many days on average." A lower DSO means faster collections and better cash flow; a rising DSO trend often signals loosening credit standards or collection problems.
Credit managers and CFOs track DSO monthly to spot collection issues early, often comparing it against the company's own stated payment terms (e.g. "net 30").
- Formula: DSO = (Accounts Receivable ÷ Net Credit Sales) × 365.
- Compare DSO to your payment terms: if your invoices say "net 30" but your DSO is 55 days, customers are paying nearly twice as slowly as agreed — a clear collections red flag.
- Trend matters more than a single snapshot: a DSO that's rising quarter over quarter, even if still "acceptable" in absolute terms, deserves investigation before it becomes a bigger cash flow problem.
What's a "good" DSO?
It depends heavily on your industry and standard payment terms — a DSO close to your stated credit terms (e.g. ~30 days for "net 30" terms) is generally healthy; significantly higher suggests collection issues.
Should I use 365 or 360 days in the formula?
365 (calendar year) is the most common convention for DSO; some finance teams use 360 for simplicity in certain international contexts, but the difference is minor for this metric.
