The calculation
DSO = accounts receivable ÷ net credit sales × days in the period. Use the same period and a consistent closing or average receivables convention when comparing results.
What it helps you investigate
DSO helps a finance team investigate collection timing. It is not the age of each unpaid invoice. Review the aging report, payment terms and sales mix alongside the result.
Common questions
How to Calculate Accounts Receivable Turnover?
Accounts receivable turnover equals net credit sales divided by average accounts receivable. Calculate average receivables by adding beginning and ending receivables, then dividing by 2. A turnover ratio of 12 means you collect receivables 12 times per year, indicating efficient collection processes.
How to Calculate Average Accounts Receivable?
Average accounts receivable equals (beginning receivables + ending receivables) ? 2 for annual calculations. For more precise monthly analysis, add all 12 month-end balances and divide by 12. This average provides a more accurate basis for calculating turnover ratios and assessing collection performance trends.
