Accounts receivable turnover ratio = net credit sales ÷ average accounts receivable. Average AR is beginning AR plus ending AR, divided by two. Days sales outstanding (DSO) = 365 ÷ the ratio.
For example, $90,000 of net credit sales against an average AR of $12,500 gives a ratio of 7.2, so you collect your receivables 7.2 times a year, or about every 51 days. A higher ratio is better. Most businesses are healthy between 5 and 10. Enter your figures below and pick your industry for a verdict against that industry’s typical range.
All figures for the same period (usually a year). Net credit sales excludes cash sales, returns, and allowances.
net credit sales / average ARThe turnover ratio is the clearest single measure of how efficiently you convert credit sales into cash. The calculator above gives you the number; the rest of this page explains what it means and how to move it.
How to use the calculator
You need three figures, all for the same period: net credit sales, your accounts receivable at the start of the period, and your AR at the end. Pull net credit sales from your income statement (exclude cash sales, returns, and allowances) and the two AR balances from your opening and closing balance sheets. Pick your industry so the verdict compares you to the right benchmark.
Average AR smooths out month-to-month swings. Turnover ratio is how many times a year you collect your average balance. DSO restates that as average days to get paid, which is usually the most actionable number.
Accounts receivable turnover ratio examples
Three sample businesses, each with one year of figures. The ratio is net credit sales divided by average AR, and DSO is 365 divided by the ratio.
| Business | Net credit sales | Beginning AR | Ending AR | Average AR | Ratio | DSO |
|---|---|---|---|---|---|---|
| Small service firm | $90,000 | $11,000 | $14,000 | $12,500 | 7.2x | 51 days |
| Software company | $1,200,000 | $95,000 | $105,000 | $100,000 | 12.0x | 30 days |
| Building contractor | $600,000 | $140,000 | $160,000 | $150,000 | 4.0x | 91 days |
The software company collects its average balance every month. The contractor waits about three months for each dollar of credit sales, so the same revenue ties up far more cash.
How do you calculate accounts receivable turnover?
Divide net credit sales by average accounts receivable for the same period. Average AR is beginning AR plus ending AR, divided by two. If net credit sales were $90,000 and average AR was $12,500, the ratio is 90,000 ÷ 12,500 = 7.2 times. Take net credit sales from your income statement, excluding cash sales, returns and allowances, and both AR balances from your balance sheets.
What is the accounts receivable turnover formula?
The accounts receivable turnover formula is net credit sales divided by average accounts receivable. The result tells you how many times in a period you collect your average AR balance. Use the same period for every input, usually a year. For a quarter, use quarterly net credit sales and replace 365 with 91 when you convert the ratio to days.
AR turnover ratio = Net credit sales ÷ Average accounts receivable
Average AR = (Beginning AR + Ending AR) ÷ 2, and DSO = 365 ÷ ratio

How do you calculate accounts receivable turnover in days?
Divide 365 by the accounts receivable turnover ratio. The result is the average number of days it takes to collect a credit sale, also called days sales outstanding (DSO) or receivables days. A ratio of 7.2 gives 365 ÷ 7.2 = 51 days. You can also go direct: average AR divided by net credit sales, times 365. Fewer days means faster collection.
How do you calculate average accounts receivable?
Add the accounts receivable balance at the start of the period to the balance at the end, then divide by two. Opening AR of $11,000 and closing AR of $14,000 give an average of $12,500. If your balance swings a lot during the year, average the 12 month-end balances instead for a truer figure. Our average accounts receivable calculator does this for you.
What is a good AR turnover ratio?
Generally 5 to 10 times per year is healthy, with higher being better. The right target depends on your industry: technology firms often run near 12, while construction and healthcare run lower because of longer payment cycles. The calculator above benchmarks your result against the industry you select.
Source: Corporate Finance Institute, AR turnover ratioWhat does an accounts receivable turnover ratio of 12 mean?
A ratio of 12 means you collect your average receivables 12 times a year, or about once every 30 days. That is strong for almost any industry and typical of well-run technology and subscription businesses. The only caution is if such a high ratio comes from credit terms so restrictive they are suppressing sales.
Is a high AR turnover ratio bad?
Usually not. A high ratio signals efficient collections, disciplined credit control, and reliable customers. It is only a concern if it reflects an overly strict credit policy that turns away good business or terms so short they dampen demand. For most companies, faster is better.
Is lower AR turnover better?
No. A lower ratio means slower collections, more cash tied up in unpaid invoices, and higher bad-debt risk. If your ratio is falling, it usually points to looser terms, slower follow-up, or customers stretching payments. The goal is a higher, faster ratio.
How can I improve my AR turnover ratio?
Invoice immediately and accurately, set shorter and clearer payment terms, offer easy online payment, and follow up on a fixed cadence instead of waiting for invoices to age. Chase the oldest and largest balances first. Our free AR action plan template gives you a ready-made collections cadence to do exactly this.
What causes AR turnover to increase?
Turnover rises when you collect faster relative to sales: tighter credit terms, prompt and accurate invoicing, consistent follow-up, online payment options, and early-payment incentives all push it up. It can also rise simply because sales grew while receivables stayed flat. A falling average AR with steady sales is the cleanest driver.
What is the 10 rule for accounts receivable?
The cross-aging "10% rule": if more than 10% of a single customer's receivables are overdue, typically past 90 days, the entire account is reclassified as high-risk rather than just the overdue portion. Lenders use it to size a borrowing base, and credit teams use it as a trigger to tighten terms.
