What is the accounts receivable turnover ratio?

It measures how many times a company collects its average accounts receivable balance during a period. Formula: Net Credit Sales ÷ Average Accounts Receivable. A higher ratio indicates faster collection.

What is days sales outstanding (DSO)?

DSO is the average number of days it takes to collect payment after a credit sale. Formula: Period Days ÷ AR Turnover Ratio. Lower DSO means faster cash collection.

It depends on your payment terms. A common guideline: DSO should be no more than 1.5× your standard payment period. If you invoice Net 30, a DSO under 45 days is generally healthy.

Should I use beginning, ending, or average AR?

Average AR — (beginning + ending) / 2 — smooths seasonal fluctuations and gives a more accurate ratio. Using only ending AR can overstate or understate the result.

What is the difference between net sales and net credit sales?

Net credit sales exclude cash sales. Using total net sales inflates the denominator and understates DSO if your business mixes cash and credit transactions. Use net credit sales for accuracy.

How does AR turnover relate to the cash conversion cycle?

DSO is the AR component of the cash conversion cycle (CCC = DSO + DIO − DPO). Reducing DSO tightens the CCC and frees up working capital.

Summary

The Receivables Turnover Calculator computes the accounts receivable turnover ratio and days sales outstanding (DSO) from net credit sales, average accounts receivable, and period length. It applies AR Turnover = Net Credit Sales / Average AR and DSO = Period Days / AR Turnover to gauge collection speed. The calculation assumes credit sales exclude cash transactions and that the receivable balance accurately represents collection patterns across the specified time frame.
