Accounts Receivable Turnover Calculator

Collection efficiency tells you how well a business turns credit sales into cash, and two figures capture it: accounts receivable turnover and Days Sales Outstanding (DSO). A high turnover paired with a low DSO points to disciplined collections. The calculator rates a DSO of 30 days or less as excellent, up to 45 days as good and up to 60 days as average; anything longer is marked as needing improvement, a sign that credit terms or follow-up procedures deserve a second look.

The turnover ratio comes from dividing Net Credit Sales by Average Accounts Receivable, which the calculator takes as the beginning and ending balances added together and halved. From there, DSO follows by dividing 365 days by that turnover ratio, so enter a full year of credit sales: one quarter's sales spread over 365 days would overstate DSO about fourfold. Together these two numbers translate the pace of your collections into figures you can track over time and stack against prior quarters.

Accuracy hinges on the inputs: use net credit sales, with cash sales and returns stripped out, rather than total revenue. Plugging in total revenue overstates turnover and makes collections look healthier than they are. Because benchmarks differ sharply from one industry to the next, the most useful comparison is against businesses similar to yours, not a generic standard.
