Assumptions & method
- Accounts receivable days (DSO) = receivables ÷ credit sales × days in the period. It is also called days sales outstanding or the average collection period.
- Credit sales are used, not total sales. If you only have total sales, the result understates DSO to the extent that some sales were paid in cash.
- AR turnover = credit sales ÷ receivables. DSO = period days ÷ AR turnover.
- Receivables basis: average mode uses (beginning + ending) ÷ 2; ending mode uses the closing balance only, which is more sensitive to growth and period-end timing.
- Period days are selectable (365, 360, or shorter). Credit sales must cover the same period as the days chosen.
- The ratio is an average. It does not show how many customers pay late, nor does it adjust for bad debts, credit notes or seasonality.

What are accounts receivable days?
When you sell on credit, cash arrives later. Accounts receivable days (DSO) converts the balance owed by customers into the average number of days of credit sales it represents. A lower figure generally means cash is collected sooner; a higher figure means more cash is tied up waiting to be paid. Comparing DSO with your own payment terms is useful: if terms are 30 days and DSO is 45, some customers are paying late or a few large invoices are outstanding. Seasonal sales or a late-period sales spike can move the ending-balance version noticeably, which is why the table also shows the average basis.
