What it means
Two companies can earn the same profit margin on sales but need very different amounts of capital to do it. A supermarket makes a thin margin on each sale but turns its assets over many times a year; a power company makes a high margin but needs enormous plant to generate each dollar of revenue.
Asset turnover captures that second dimension. Combined with profit margin, it explains return on assets: a business can earn a good return by making a lot on each sale or by making a little on many sales from a small asset base.
The ratio is most useful for tracking a business over time and against direct competitors. A falling ratio means assets are growing faster than sales: the company may be over-investing, carrying too much inventory, letting receivables balloon or holding idle plant.
A rising ratio means the business is getting more from what it has, though it can also mean the company is starving itself of investment and running old equipment, which shows up later as falling sales or rising costs. Interpretation depends heavily on industry and business model.
A company that leases its premises will show a higher asset turnover than an identical one that owns them, because the owned buildings sit on the balance sheet. A company that has recently made a large acquisition will show a lower ratio because goodwill and acquired assets appear before the acquired revenue does.
Very old, heavily depreciated asset bases inflate the ratio. Comparisons should therefore be made with care and alongside the fixed asset turnover and working capital ratios that break the picture down.
Analysts use the ratio in the DuPont framework, which decomposes return on equity into profit margin, asset turnover and financial leverage. It shows whether a company's return comes from pricing power, operational efficiency or borrowing, three very different strengths.
In practice
Real-world examples.
Example
A discount grocery chain with $50 billion of sales and $12 billion of assets has an asset turnover of about 4.2, reflecting rented stores, fast-moving stock and cash sales.
Example
A water utility with $2 billion of sales and $10 billion of pipes, reservoirs and treatment plants has a turnover of 0.2, which is normal for its industry.
Example
A software company's asset turnover falls from 1.5 to 0.9 after a large acquisition adds goodwill to the balance sheet, and recovers over the following years as the acquired revenue grows.
Think of it
“Asset turnover is like measuring how many times a restaurant fills its tables each night-more turns mean more revenue from the same space.
Formula
Calculation
Asset Turnover Ratio = Revenue / Average Total Assets
Average Total Assets = (Total Assets at start of year + Total Assets at end of year) / 2
Return on Assets = Net Profit Margin x Asset Turnover
Worked example. A furniture retailer reports:
- Revenue for the year: $9,000,000
- Total assets at the start of the year: $3,800,000
- Total assets at the end of the year: $4,200,000
- Net profit: $360,000
Average total assets = ($3,800,000 + $4,200,000) / 2 = $4,000,000
Asset turnover = $9,000,000 / $4,000,000 = 2.25
Net profit margin = $360,000 / $9,000,000 = 4.0%
Return on assets = 4.0% x 2.25 = 9.0% (check: $360,000 / $4,000,000 = 9.0%)
Comparison. A furniture manufacturer with revenue of $9,000,000, average assets of $7,500,000 and net profit of $630,000 has asset turnover of 1.2 and a margin of 7.0%, giving the same 8.4% return on assets by a different route: the manufacturer earns more per sale but needs far more capital to make each sale.Case study
Seen in the real world.
A distributor of industrial fasteners had seen its asset turnover slide from 2.8 to 1.9 over four years while revenue grew 20%. The board assumed the business was healthy because sales and profit were rising. The finance director broke the ratio down and found that inventory had doubled as the company added product lines, and receivables had grown from 45 to 68 days as sales staff offered longer terms to win business.
Fixed assets had barely changed. Every extra dollar of sales was requiring 50 cents of extra working capital, all of it borrowed. The company rationalised its range, cutting 4,000 slow-moving items, and tied sales commissions to cash collected rather than invoices raised.
Over two years inventory fell by a third and receivables returned to 48 days; asset turnover recovered to 2.6 and the company repaid $3 million of borrowings without sales falling. Return on assets rose from 6% to 10% with no change in the profit margin.
Watch out
Common mistakes.
- Comparing asset turnover across industries. The ratio is driven by business model; compare like with like.
- Using year-end assets instead of the average, which distorts the ratio for growing or shrinking businesses.
- Reading a rising ratio as unambiguously good. It can mean underinvestment as easily as efficiency.
Questions
People also ask.
What is a good asset turnover ratio?
It depends on the industry. Retailers often exceed 2.0; capital-intensive industries are often below 0.5. The trend matters more than the level.
How is asset turnover different from inventory turnover?
Inventory turnover measures how quickly stock is sold. Asset turnover measures revenue against all assets, including fixed assets and receivables.
Why does asset turnover matter for return on equity?
In the DuPont formula, return on equity equals profit margin times asset turnover times leverage. Improving turnover raises returns without needing higher margins or more debt.
