What it means
The ratio takes revenue for the year and divides it by capital employed, which is usually total assets less current liabilities, or equivalently equity plus long term debt. Because revenue covers a period and capital is measured at a point in time, careful analysts use the average of opening and closing capital.
What makes capital turnover useful is its role in the wider return equation. Return on capital employed is simply operating margin multiplied by capital turnover, so a business can improve returns either by charging more relative to costs or by working its assets harder.
That relationship explains a lot of business models. A discount grocer accepts thin margins and survives on very high turnover of its capital, while a luxury jeweller turns its capital over slowly and relies on a wide margin per sale.
Practical improvements usually come from the working capital side rather than from selling factories. Collecting receivables faster, holding less stock and negotiating longer supplier terms all reduce capital employed and lift turnover without touching revenue at all.
The main trap is that the ratio can be flattered by an ageing asset base. A company with heavily depreciated plant shows a small capital figure and an impressive turnover, right up to the point where everything needs replacing at once.
Leased assets are a second complication worth watching, because accounting rules now bring most leases onto the balance sheet as right of use assets. A business that once rented its premises and reported a flattering ratio may show a noticeably lower one today without anything real having changed.
In practice
Real-world examples.
Example
A national convenience chain runs on an operating margin of just 3% but turns its capital over eight times a year. The resulting 24% return on capital employed beats many businesses with far more comfortable margins.
Example
A specialist engineering firm improves its capital turnover from 1.8 to 2.2 by cutting average stock holding from ninety days to sixty. No extra sales were needed, since the gain came entirely from releasing cash tied up in the warehouse.
Example
A hotel group's capital turnover falls sharply in the year it opens two new properties, because the buildings sit on the balance sheet before they generate a full year of room revenue. Management reports the ratio excluding pre-opening assets so the underlying trend stays visible.
Think of it
“Capital turnover shows how hard your invested capital works to produce revenue.
Formula
Calculation
Capital turnover = revenue / capital employed, where capital employed = total assets - current liabilities
A packaging manufacturer reports revenue of $48,000,000 for the year. Its balance sheet shows total assets of $22,000,000 and current liabilities of $6,000,000, so capital employed is $22,000,000 - $6,000,000 = $16,000,000.
Capital turnover = $48,000,000 / $16,000,000 = 3.0 times. Each dollar tied up in the business produced three dollars of sales during the year.
Linking that to profitability, the company's operating margin is 8%, giving operating profit of $48,000,000 x 0.08 = $3,840,000. Return on capital employed is $3,840,000 / $16,000,000 = 24%, which is the same as multiplying the 8% margin by the turnover of 3.0.Case study
Seen in the real world.
The following is an illustrative and entirely fictional story. Grindale Components, an invented parts supplier, spent three years trying to lift profits by raising prices, and watched its operating margin improve from 6% to 7% while volumes slipped and returns barely moved.
A new operations director in this fictional example looked instead at capital turnover, which sat at a sluggish 1.6. By moving three slow selling product lines to a make to order basis and tightening collections from thirty eight days to twenty six, the invented company released roughly $4,000,000 of capital and lifted turnover to 2.1 on similar revenue.
The combined effect took return on capital employed from about 11% to nearly 15% without a single price rise. Grindale's illustrative experience is a reminder that the denominator of a return ratio is often the easier half to change.
Watch out
Common mistakes.
- Comparing capital turnover across different industries, since asset heavy sectors such as utilities will always look worse than asset light service businesses.
- Using year end capital rather than the average, which distorts the ratio badly in any year with a large acquisition or disposal.
- Chasing a higher ratio by starving the business of investment, which lifts turnover briefly and damages capacity later.
Questions
People also ask.
Is a higher capital turnover always better?
Generally yes within an industry, but an unusually high figure can signal underinvestment or assets so old they are close to failure.
How does capital turnover relate to asset turnover?
Asset turnover divides revenue by total assets, while capital turnover deducts current liabilities first, so it focuses on the longer term funding of the business.
Which lever should a business pull first, margin or turnover?
Turnover is often quicker, because reducing stock and collecting invoices faster can be done in months without needing customers to accept higher prices.
