The asset turnover ratio is net sales divided by average total assets. It shows how much in sales a business produces for every dollar of assets it holds, so it tells you how hard your assets are working.
CFI calls it an efficiency ratio, and it's also known as the total asset turnover ratio. A company with a high asset turnover ratio operates more efficiently than competitors with a lower one, CFI says. It doesn't tell you anything about profit, only about how much selling your assets support.
The asset turnover formula
CFI writes it as net sales divided by total or average assets. Both parts have a specific meaning:
- Net sales is revenue after deducting sales returns, sales discounts and sales allowances.
- Average total assets is the average of total assets at the end of the current and the preceding financial year.
- CFI notes that an analyst may use either average assets or end-of-period assets.
CFI's guide to return on assets makes the case for the average: it gives a more accurate measure when asset levels change a lot during the period.
A worked asset turnover example
CFI's example is Company A, in US dollars as of October 2026. The net sales and average assets lines are derived from CFI's figures, and the ratio matches the one CFI prints.
| Item (CFI's Company A) | Value |
|---|---|
| Beginning total assets | $199,500 |
| Ending total assets | $199,203 |
| Sales | $325,300 |
| Sales returns | $15,000 |
| Net sales | 310,300 (derived: sales minus returns) |
| Average total assets | 199,351.5 (derived: the two asset figures added and halved) |
| Asset turnover | 1.5565 |
So for every dollar in total assets, CFI says Company A generated $1.5565 in sales. Check the maths yourself: 310,300 divided by 199,351.5 gives 1.5565.
How to calculate asset turnover
- Take sales and subtract returns, discounts and allowances to get net sales.
- Add the opening and closing total assets and divide by two.
- Divide net sales by average total assets.
- Compare the result only with companies in the same industry.
Your sales figure comes from the profit and loss statement and your assets from the balance sheet, so you need both reports for the same period. If those two still blur together, here's my guide to the P&L vs the balance sheet.
The catch: only compare within one industry
This ratio means nothing on its own, and it means less than nothing across industries. CFI compares four hypothetical companies: A and B in fast food, C and D in telecommunications. It says it would be incorrect to compare Company A with Company C, because they're in different industries. Comparing A with B is fair, and there Company B comes out more efficient, which CFI says may mean A has poor sales or fixed assets that aren't being used to full capacity.
The reason is built into how industries work. CFI says industries with low profit margins tend to generate a higher ratio, and capital-intensive industries tend to report a lower one. A business that needs heavy equipment will always look slow next to one that sells high volumes from a small base.
What drags asset turnover down
CFI says a higher ratio is favourable, because it shows more efficient use of assets. A lower ratio points to poorer efficiency, and CFI names three usual causes:
- Obsolete inventory or sluggish sales.
- Receivables that take too long to collect, or credit accounts that pile up.
- Property, plant and equipment that sits unproductive instead of working at full capacity.
Each one is a question you can ask about your own business. Is there stock nobody's buying? Are customers paying late? Is there kit you paid for that isn't earning?

Operating asset turnover: a variation
CFI also describes the operating asset turnover ratio, which only counts the assets essential to day-to-day operations. It's used when a company holds large assets that have nothing to do with how it earns. In CFI's example, an analyst strips out vacant land worth $230,000 and finds $2.22 of revenue for every dollar of operating assets.
Asset turnover vs return on assets
The two ratios share a bottom line but answer different questions. CFI's return on assets is net income divided by average total assets, so it measures profit per dollar of assets, while asset turnover measures sales per dollar of assets. If you want the profit side of the picture, start with your net profit margin.
My verdict on asset turnover
The ratio asks whether your assets are working or just sitting there. That's a useful question for any business that owns stock, equipment or property. Work it out once a year, compare it with your own previous years and with businesses in your sector, and if it's falling, look at the three usual suspects: slow stock, slow payers and idle kit. Don't compare yourself with a business in a completely different industry. CFI's whole point is that it won't tell you anything.
Frequently asked questions
What is the formula for the asset turnover ratio?
Net sales divided by average total assets. CFI defines net sales as revenue after returns, discounts and allowances, and average total assets as the average of this year's and last year's closing total assets.
What is a good asset turnover ratio?
CFI says a higher ratio is favourable, but there's no single good number. It depends on the industry, so compare only with companies in the same sector.
Why can't you compare asset turnover across industries?
CFI says industries vary in how capital-intensive they are. Low-margin industries tend to have higher ratios and capital-intensive industries lower ones.
Should I use average or ending total assets?
CFI says an analyst may use either. Average assets give a fairer view when your asset base changes during the year.
How is asset turnover different from return on assets?
Asset turnover measures sales per dollar of assets. Return on assets, in CFI's definition, measures net income per dollar of assets.
