The term “net credit sales” refers to the amount of revenue the company has generated over the specific period of time (usually a month, quarter, or year) and paid by credit. This includes all sales on credit, minus sales returns, and sales discounts.
The term “average accounts receivable” refers to the average between a company’s accounts receivable balance at the start of the relevant period and its accounts receivable balance at the end of the period, divided by two.
A typical example would be a store which sells furniture to major hotel chains. Over the course of a quarter, the store made €350,000 in gross sales. The accounts receivable at the start of the quarter were €40,000 and at the end of the quarter were €70,000. The accounts receivable turnover ratio for this quarter would be:
Accounts Receivable Turnover Ratio = €350,000 – €40,000 / (€40,000 + €70,000 / 2) = 5.6
The accounts receivable turnover ratio in this case is 5.6.
This figure can then be used to calculate the average number of days it takes customers to settle their credit invoices, by dividing the number of days in the specific period (here a quarter, 91 days) by the accounts receivable turnover ratio.
Accounts Receivable Turnover in Days = 91 / 5.6 = 16.25 days.
This figure indicates that, when the credit period is 91 days, customers on average settle their invoices within 16.25 days.
