Accounts receivable turnover ratio: formula & example
The accounts receivable turnover ratio measures how many times a year you collect your average receivables — a higher number means you turn invoices into cash faster. It's the mirror image of DSO: where DSO counts the days a payment takes, turnover counts the cycles, and the two move in opposite directions.
What is the accounts receivable turnover ratio?
The accounts receivable turnover ratio is an efficiency metric that shows how many times, on average, a business collects its outstanding receivables over a period — usually a year. A turnover of 6 means you collected the equivalent of your average receivables balance six times. Higher turnover signals faster collection and healthier cash flow.
For a small B2B service company, that number is a quick read on a question that matters every month: are invoices turning into cash quickly enough to fund the work you've already delivered? It rolls up the whole collection process — how fast you bill, how clear your terms are, and how reliably you follow up — into a single figure you can track over time.
The accounts receivable turnover formula
The formula is Net Credit Sales ÷ Average Accounts Receivable. Net credit sales are your sales made on credit over the period, less returns and allowances. Average accounts receivable is (beginning AR + ending AR) ÷ 2— using the average smooths out the swing between the start and end of the period, so a single busy or quiet month doesn't distort the result.
Use creditsales, not total revenue. Cash sales are collected the instant they happen, so they were never receivables and including them understates how long credit customers actually take to pay. If you can't cleanly separate the two, total sales is a usable approximation — just apply it consistently so your trend stays comparable from one period to the next.
A worked example
The arithmetic is easiest to see with real numbers. Suppose a consultancy has net credit sales of €1,200,000 over the year. It started the year with €180,000 in receivables and ended with €220,000. Here is each step:
- Average AR = (€180,000 + €220,000) ÷ 2 = €200,000.
- Turnover = €1,200,000 ÷ €200,000 = 6.0 times.
So this business collects its average receivables six times a year. On its own, “6” is abstract — which is why it helps to translate it back into days, the unit most people actually feel.
How accounts receivable turnover relates to DSO
Turnover and Days Sales Outstanding are two views of the same thing. Convert between them with DSO ≈ 365 ÷ turnover. The consultancy above, with a turnover of 6.0, has a DSO of 365 ÷ 6 ≈ 60.8 days— on average, just over two months pass between invoicing and getting paid.
Because they're inverses, a higher turnover always maps to a lower DSO. This table shows the relationship at a few common values:
| AR turnover ratio | Approx. DSO (days) | What it suggests |
|---|---|---|
| 4 | ~91 days | Collection is slow; cash is tied up for roughly a quarter |
| 6 | ~61 days | Around two months — common where Net 30 slips in practice |
| 8 | ~46 days | Reasonably tight for Net 30 terms |
| 12 | ~30 days | Fast: receivables turn over monthly |
Many people find days more intuitive than cycles, so it's worth working in whichever unit your team understands best. You can compute the days side directly with our free DSO calculator, and see how the result stacks up against a good DSO by industry.
What's a good accounts receivable turnover ratio?
A “good” accounts receivable turnover ratio is one that's high relative to your industry and your own payment terms, and stable or improving over time. There's no universal target: a business on Net 15 should turn over far faster than one on Net 60, so the same number can be excellent in one sector and poor in another.
Higher is generally better, because it means cash arrives sooner. But an unusually high ratio isn't always a win. If your terms are far tighter than your market's, you may be collecting quickly at the cost of sales — customers who'd happily buy on Net 30 go elsewhere when you insist on Net 7. The most useful comparison is almost always against yourself:
- Your own trend. Is turnover rising or falling quarter over quarter? Direction often matters more than the absolute figure.
- Your stated terms.If you bill Net 30 but the implied DSO is 60 days, the gap is the part driven by late payment — and the part you can actually act on.
- Your peers. Compare against businesses with similar terms and customers, not a one-size benchmark.
How to improve your accounts receivable turnover ratio
Improving turnover means collecting the same receivables in fewer days, which lifts the ratio. You don't do that by being aggressive — you do it by being fast and consistent. The biggest levers are the same ones that bring DSO down.
Invoice fast and bill accurately
The collection clock only starts when the invoice goes out. Every day you wait to bill is a day added before the customer has even seen the amount, and a disputed line item or missing PO number is one of the most common reasons an invoice quietly stalls. Send invoices the moment work is delivered, and get them right the first time.
Set clear terms and follow up consistently
State the due date in days, put it on the invoice and in the first email, then chase on a predictable cadence — a short reminder a few days before the due date prevents far more lateness than chasing after the fact. The key word is consistent: ad-hoc chasing whenever someone remembers is exactly what lets receivables age. Our guide on how to reduce DSO walks through the full playbook.
Use your aging report to focus
You can't improve every account at once, so work the balances that move the ratio most. An accounts receivable aging reportgroups what's owed by how overdue it is, showing exactly where your cash is stuck so you can prioritise the oldest and largest balances first.
The bottom line
The accounts receivable turnover ratio — net credit sales divided by average receivables — tells you how many times a year you convert invoices into cash, and it's the inverse of DSO (DSO ≈ 365 ÷ turnover). Higher generally means faster collection and healthier cash flow, but read it against your own terms, your trend, and your industry rather than a fixed target. To raise it, invoice fast, set clear terms, follow up consistently, and let your aging report tell you where to start — the same habits that keep DSO low keep turnover high.
Frequently asked questions
What is the accounts receivable turnover ratio?
It's an efficiency metric showing how many times a year a business collects its average receivables. A turnover of 6 means you collected the equivalent of your average AR balance six times. A higher ratio signals faster collection and healthier cash flow.
How do you calculate AR turnover?
Divide net credit sales by average accounts receivable. Average AR is (beginning AR + ending AR) ÷ 2. For example, net credit sales of €1,200,000 with average receivables of €200,000 gives a turnover of 1,200,000 ÷ 200,000 = 6.0 times.
What is a good AR turnover ratio?
There's no universal target — a good ratio is high relative to your industry and your own payment terms, and stable or improving over time. A business on Net 15 should turn over faster than one on Net 60, so compare against your own trend and your peers rather than a fixed number.
What's the difference between AR turnover and DSO?
They're two views of the same thing. AR turnover counts how many collection cycles you complete in a year, while DSO counts the average days a payment takes. They're inverses: DSO ≈ 365 ÷ turnover, so a turnover of 6 corresponds to a DSO of about 61 days.
Should I use total sales or credit sales?
Use net credit sales. Cash sales are collected instantly and were never receivables, so including them understates how long credit customers actually take to pay. If you can't separate the two cleanly, total sales is a usable approximation as long as you apply it consistently.
