AR Turnover Ratio Explained

Accounts Receivable Turnover Ratio measures how many times a company collects its average accounts receivable balance during a specific period. It is calculated by dividing net credit sales by average accounts receivable.

A higher ratio means faster collection. If your AR turnover ratio is 12, you collect your average receivables 12 times per year — roughly every 30 days. A ratio of 6 means you're collecting every 60 days, which signals slower payments and higher cash flow risk.

AR turnover ratio is the inverse of DSO and is particularly useful for comparing collection efficiency across companies of different sizes. While DSO is measured in days (intuitive for operations teams), AR turnover ratio is a pure efficiency metric favored by CFOs, lenders, and investors for financial analysis.

Key Points

What You Need to Know About AR Turnover Ratio

Higher is better. A high ratio means you're collecting receivables quickly and efficiently. A low ratio means money is stuck in invoices.
It's the inverse of DSO. DSO = 365 / AR Turnover Ratio. A turnover of 12 = DSO of ~30 days. A turnover of 6 = DSO of ~61 days.
Use average AR, not ending AR. Average AR (beginning + ending / 2) smooths out seasonal fluctuations and gives a more accurate picture than a point-in-time snapshot.
Exclude cash sales. Only use credit sales in the numerator. Including cash sales inflates the ratio and makes collections look better than they are.
Trend over time matters most. A declining ratio — even if still "good" — signals that customers are paying slower and collections may need attention.

Formula

How to Calculate AR Turnover Ratio

AR Turnover Ratio Formula

AR Turnover = Net Credit Sales ÷ Average Accounts Receivable

Average AR = (Beginning AR + Ending AR) / 2. Use the same time period for both numerator and denominator — annual sales with annual average AR, or quarterly sales with quarterly average AR.

Example

AR Turnover Ratio in Practice: B2B Example

Scenario: Software Services Company, Annual

Net Credit Sales (annual): $6,000,000

Beginning AR: $450,000

Ending AR: $550,000

Average AR: ($450,000 + $550,000) / 2 = $500,000

AR Turnover Ratio: $6,000,000 / $500,000 = 12.0 — excellent

Equivalent DSO: 365 / 12 = 30.4 days

Next year: Revenue grows to $7.2M but ending AR balloons to $900K (average AR = $675K). New ratio: 10.7. DSO jumps to 34 days. Revenue grew 20% but collections slowed — a sign that the company is extending credit to riskier customers or follow-up has lapsed.

FAQ

AR Turnover Ratio FAQ

What is a good AR turnover ratio?

A good AR turnover ratio for B2B companies is typically 8-12, meaning the company collects its average receivables 8-12 times per year (roughly every 30-45 days). A ratio above 12 is excellent. Below 6 indicates slow collections and potential cash flow issues. The ideal ratio varies by industry and payment terms.

How do you calculate AR turnover ratio?

AR Turnover Ratio = Net Credit Sales / Average Accounts Receivable. Average AR is calculated as (Beginning AR + Ending AR) / 2. For example, if annual net credit sales are $6M and average AR is $500K, the ratio is 12 — meaning you collect your average AR 12 times per year.

What is the difference between AR turnover ratio and DSO?

They measure the same thing from different angles. AR Turnover Ratio tells you how many times per year you collect your average AR (higher is better). DSO tells you the average number of days to collect (lower is better). You can convert between them: DSO = 365 / AR Turnover Ratio. A ratio of 12 equals a DSO of about 30 days.
