- Asset turnover divides sales by average total assets: how much in sales each dollar invested in the business generates.
- Costco turned its assets 3.75 times in fiscal 2025 ($275,235 million of sales on $73,465 million of average assets); Merck, 0.51 times in 2025.
- Multiply it by net margin and you get ROA; add leverage and you get ROE: it's one of the three pieces of the DuPont breakdown.
- Low turnover isn't bad in itself: Merck turns its assets seven times more slowly than Costco and had a higher ROA in 2025, because its margin is far higher.
- Compare turnover with rivals in the same sector, and watch that it doesn't fall several years in a row without margin rising.
Introduction
Costco sold $275,235 million worth of goods in fiscal 2025 on average assets of $73,465 million: every dollar of warehouses, merchandise and cash generated $3.75 of sales. Merck, the drugmaker, sold $65,011 million in 2025 on average assets of $126,986 million: $0.51 per dollar. Costco squeezes seven times more sales out of its assets. Does that make it the better business? By the end of this lesson you'll see that it doesn't, and why.
Explanation
The asset turnover ratio divides the year's sales by total assets. It measures how much business a company moves with what it owns: stores, factories, inventory, money owed by customers, cash, patents. A turnover of 2 means every dollar of assets generates $2 of sales a year.
Picture a produce stand and a jewelry store on the same block, each with $100,000 tied up in the shop and its stock. The produce stand restocks every few days and sells $400,000 a year, making a few cents a pound: a turnover of 4. The jewelry store keeps its display cases full for months and sells $80,000 a year, but makes a lot on each piece: a turnover of 0.8. Neither one is doing anything wrong. They're two business models, and turnover tells you which one you're looking at.
Total vs. fixed assets
Total asset turnover uses the whole balance sheet. Fixed asset turnover uses only property, plant and equipment (buildings, machinery, stores) and shows how capital-intensive a business is. Kaplio's table and this lesson use total asset turnover.
DuPont, the other way around
In the ROA lesson we split ROA into net margin times turnover. Here we read it from the other side: turnover is half the engine of profitability. Add leverage and you get to ROE:
ROE = net margin × asset turnover × (assets / shareholders' equity).
Two companies with the same ROE can get there by opposite routes: one with a fat margin and slow turnover, the other with a thin margin and fast turnover. Turnover tells you which route each one takes, and what risk comes with it: for the thin-margin company, a couple of points off its prices can wipe out the profit.
Formula
Asset turnover = Revenue / Average total assets
Average total assets = (Assets at the start of the fiscal year + Assets at year-end) / 2
Fixed asset turnover = Revenue / Net property, plant and equipment
ROA = Net margin × Asset turnover
ROE = Net margin × Asset turnover × (Assets / Shareholders' equity)
Example
The table below compares the asset turnover of four big US retailers: Walmart, Costco, Target and Kroger. Read it as dollars of sales a year for every dollar of assets. All four come in above 1, because they live on selling a lot at a thin margin; notice which one gets the most out of its stores. The table uses the trailing twelve months, so it may not match the fiscal-year calculations below to the decimal.
Step by step: Costco, fiscal 2025 (year ended August 31, 2025, Form 10-K annual report, millions of dollars)
1. Sales for fiscal 2025: 275,235.
2. Total assets: 69,831 at the start of the year and 77,099 at year-end. Average: 73,465.
3. Turnover = 275,235 / 73,465 = 3.75 times.
4. Net income of $8,099 million: a net margin of 2.94%.
5. ROA = 2.94% × 3.75 = 11.0%.
6. With average shareholders' equity of $26,393 million, every shareholder dollar supports $2.78 of assets: ROE = 11.0% × 2.78 = 30.7%.
Costco earns less than 3 cents on every dollar it sells. And yet it posts an ROE of 30%, because it moves merchandise at a speed few retailers can match.
Your turn. Merck had revenue of $65,011 million in 2025 and earned $18,254 million. Its total assets were $117,106 million at the end of 2024 and $136,866 million at the end of 2025. Work out its turnover on average assets and its ROA.
Before you look: do you think Merck, which turns its assets seven times more slowly than Costco, earns less per dollar of assets? Answer: average assets of $126,986 million, turnover of 0.51 times, a net margin of 28.1% and an ROA of 14.4% in 2025, above Costco's 11.0%. A drug patent doesn't turn over, but it leaves a lot of margin on every sale.

How to read it
How to read it
Turnover isn't good or bad in the abstract: it describes the business model. What is a bad sign is turnover below that of direct rivals, or turnover that falls several years in a row without margin rising to make up for it. Rough ranges for total asset turnover (these are not thresholds on Kaplio's stock page):
| Sector | Low | Typical | High |
|---|---|---|---|
| Retail and grocery | below 1.5 | 1.5-2.5 | above 2.5 |
| Industrials and machinery | below 0.6 | 0.6-1 | above 1 |
| Software and pharma | below 0.4 | 0.4-0.7 | above 0.7 |
| Utilities and telecom | below 0.2 | 0.2-0.4 | above 0.4 |
Microsoft, for example, turned its assets 0.48 times in fiscal 2026 ($331,839 million of revenue on $688,690 million of average assets), in line with a drugmaker: its data centers weigh heavily on the balance sheet.
Pitfalls and limitations
1. Old, fully depreciated assets. A company whose stores or factories are decades old carries them at almost nothing on the balance sheet. Its turnover looks high on paper, but it will have to invest to replace them.
2. A big acquisition. If a company buys another one near year-end, closing assets jump while the acquired company's sales barely count that year. Using average assets smooths this out; even so, check whether turnover is falling because of the business or because of the deal.
3. Leasing vs. owning. A chain that buys its stores carries more assets than one that leases them. Since 2019, long-term leases have been on the balance sheet as right-of-use assets, which narrows the gap between the two but doesn't close it.
4. Turning faster by selling cheaper. Cutting prices lifts sales and turnover, but it can sink the margin. Always look at both pieces together.
Case in point: Target, higher margin but lower returns
In fiscal 2025, which ended January 31, 2026, Target sold $104,780 million and earned $3,705 million: a net margin of 3.54%, above Walmart's 3.07% in its fiscal 2026, which ended on the same date. But Target turned its assets 1.79 times (on $58,630 million of average assets) and Walmart 2.61 times. The result: an ROA of 6.3% for Target against 8.0% for Walmart. Earning more on each sale doesn't help if the inventory and the stores are working less hard. That's why, in retail, turnover matters almost as much as margin.

Frequently asked questions
What does the asset turnover ratio tell you?
It tells you how much in sales a company generates for every dollar of assets. A turnover of 3 means $3 of sales a year for each dollar invested. It runs high in high-volume, low-margin models like Costco, at 3.75 times in fiscal 2025, and low in pharma or software, which make up for it with margin.
What is a good asset turnover ratio?
There's no single answer, because turnover describes the business model. As a rough guide, retailers and grocers above 2.5 are on the high side, industrial companies above 1, and software and pharma companies above 0.7. The warning signs are turnover below direct rivals, or turnover that falls for several years without margin improving.
What is the difference between fixed asset turnover and total asset turnover?
Total asset turnover divides sales by the whole balance sheet: cash, receivables, inventory and facilities. Fixed asset turnover uses only property, plant and equipment, such as stores, factories and machinery. The first measures the efficiency of the whole business; the second, how capital-intensive it is. Always compare the same version across companies.
