To calculate your accounts receivable turnover ratio, divide net credit sales by average accounts receivable. Average AR is your beginning balance plus ending balance, divided by two. The calculator above does it instantly and converts the result into days sales outstanding (DSO), the average number of days you take to get paid.
For example, $90,000 of net credit sales against an average AR of $12,500 gives a ratio of 7.2, meaning you collect your receivables 7.2 times a year, or roughly every 51 days. A higher ratio is better. Most businesses are healthy between 5 and 10, but the calculator scores your number against your specific industry so you know whether to celebrate or tighten collections. Enter your figures above, then read the sections below to interpret and improve your result.
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.
How do I calculate the AR turnover ratio?
Divide net credit sales by average accounts receivable for the same period. Average AR is (beginning AR + ending AR) divided by two. If net credit sales were $90,000 and average AR was $12,500, the ratio is 90,000 divided by 12,500, which is 7.2 times. The calculator above does this and the DSO conversion for you.
What is the formula for AR turnover?
AR turnover ratio = Net credit sales ÷ Average accounts receivable
Average AR = (Beginning AR + Ending AR) ÷ 2, and DSO = 365 ÷ ratio

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.
