ROCE in One Line
Return on capital employed, or ROCE, measures how much operating profit a business earns for every pound of long-term money tied up in it.
ROCE = operating profit ÷ capital employed × 100
If a company makes £84,000 of operating profit and has £250,000 of capital employed, its ROCE is 84,000 ÷ 250,000, which is 33.6%. Every £1 invested in the business, whether it came from the owners or from long-term lenders, produced about 34p of profit before interest and tax in the year.
That makes ROCE one of the few ratios that joins the profit and loss account to the balance sheet. A margin tells you how much of each sale you keep. ROCE tells you whether the profit is worth the money it took to earn it.
The Two Parts of the Formula
Operating profit
The top line of the formula is operating profit, also called profit before interest and tax, or EBIT. It is the profit from trading after all running costs, including depreciation, but before interest and corporation tax. We explain where it sits on the P&L in gross profit vs net profit.
You use profit before interest because the bottom line includes the funding of the business. Capital employed includes long-term loans, so the profit has to be the profit available to pay everyone who put that money in, lenders as well as shareholders. Using profit after interest is the single most common exam mistake with this ratio.
Capital employed
Capital employed is the long-term funding of the business. There are two ways to get it, and they give the same answer:
Capital employed = total assets − current liabilities
Capital employed = equity + non-current liabilities
They match because of the accounting equation. On a set of UK company accounts, the first version is the line called "total assets less current liabilities", which sits partway down the balance sheet. You can read it straight off.
The second version is how A-level textbooks usually put it: share capital plus reserves (mostly retained earnings) plus long-term borrowings.
A Worked Example
Hartley Print Ltd is a commercial printer in Watford with a 30 June year end. We used the same company in our guide to the gearing ratio, so if you have read that one the numbers will look familiar.
For the year to 30 June 2026:
| Item | Amount |
|---|---|
| Turnover | £620,000 |
| Operating profit | £84,000 |
| Interest paid | £11,000 |
| Equity (share capital £100 plus retained earnings) | £150,000 |
| Bank loan due after more than one year | £72,000 |
| Hire purchase due after more than one year | £28,000 |
| Capital employed | £250,000 |
The overdraft, the next twelve months of loan and HP repayments, the director's loan account, trade creditors, VAT and tax are all current liabilities, so they are not in capital employed.
ROCE = 84,000 ÷ 250,000 × 100 = 33.6%
Breaking it down
ROCE is the product of two other numbers, and splitting it this way is where it gets useful:
ROCE = operating margin × asset turnover
- Operating margin = 84,000 ÷ 620,000 = 13.5%
- Asset turnover = 620,000 ÷ 250,000 = 2.48 times
13.5% × 2.48 = 33.6%. Hartley keeps about 13.5p of every £1 of sales as operating profit, and each £1 of capital produces about £2.48 of sales a year.
That split tells you there are only two ways to improve ROCE. Make more profit on each sale, which is the story told by net profit margin and gross margin. Or get more sales out of the same capital, by using machines for more hours, collecting debtors faster or carrying less stock. A supermarket and a law firm can have the same ROCE by completely different routes.
Five Versions of the Formula
As with gearing, "ROCE" in the wild is a family of formulas. Here is what the common versions give for Hartley.
| Version | Calculation | Result |
|---|---|---|
| Post-tax (NOPAT) ROCE | (84,000 × 75%) ÷ 250,000 | 25.2% |
| Funding view, all borrowing and the director's loan included | 84,000 ÷ (150,000 + 140,000 + 45,000) | 25.1% |
| Standard year-end ROCE | 84,000 ÷ 250,000 | 33.6% |
| Average capital employed (opening £210,000) | 84,000 ÷ 230,000 | 36.5% |
| Excluding surplus cash of £25,000 | 84,000 ÷ 225,000 | 37.3% |
Which should you use?
- Studying for A-level Business or AAT: the standard year-end version, unless the question says otherwise.
- ACCA and CIMA: usually the standard version too, but read the question. If you are given opening and closing figures, the examiner may want an average.
- Analysts and investment sites: often the post-tax version, which some US sources call return on invested capital. Wall Street Prep, for example, divides NOPAT by average capital employed.
- Running your own business: use average capital employed if the balance sheet has changed a lot during the year, and pick one version and stay with it. The trend across three or four years is worth far more than any single figure.
The funding view is worth a mention because it is what a small business owner often means when they ask "what am I earning on the money in this business?". It counts the overdraft and the director's loan account as capital, because in most owner-managed companies both are permanent in practice.
What Is a Good ROCE?
Most UK textbooks and investment sites say that a ROCE above about 15% to 20% is good. We think that is a fair starting point with two conditions.
First, compare it with what the money costs. Hartley borrows at around 7.5%, which is about 5.5% after corporation tax relief. A business earning 33.6% on its capital is creating value. One earning 6% is barely covering the cost of its loans and would do better, on paper, repaying them. With Bank Rate held at 3.75% in September 2026, the minimum acceptable ROCE is higher than it was when rates were near zero. A ROCE that looked fine in 2021 may not clear the bar now.
Second, compare it with the right sector. The Office for National Statistics publishes a net rate of return for UK private non-financial companies. For 2024 it was 10.3% overall, 11.7% for manufacturing and 15.2% for services. Those figures are measured on a national accounts basis with assets at replacement cost, so they are not directly comparable with a ROCE from your own accounts. They do show the pattern. Asset-heavy industries earn lower returns on capital than service businesses that need little more than laptops and people.
A property company earning 6% on a portfolio of let houses and a recruitment agency earning 60% might both be well run. What matters is your ROCE against businesses like yours, and against your own last three years.
Why Small Company ROCE Often Flatters
This is the part the textbooks leave out, and it matters for almost every owner-managed company we look at.
1. The director is underpaid on paper
Hartley's director takes a salary of £12,570 and the rest as dividends. That is a normal tax-efficient approach, which we explain in directors' remuneration. But dividends are not a cost in the P&L, so operating profit includes the value of the director's full-time work.
If Hartley had to hire a general manager to do that job, it would cost around £58,000 a year once you add employer's national insurance at 15% and a workplace pension. That is roughly £44,000 more than the director costs the company today.
Take that out and operating profit falls to about £40,000. ROCE drops from 33.6% to 16%. Still respectable, but a very different story. When someone quotes a high ROCE for a small company, our first question is always who is doing the work for free.
This is exactly the adjustment a buyer makes when valuing a business, and it is why owners are sometimes surprised by offers. The buyer is paying for the return the business earns without its founder, not with them.
2. Old assets make returns look better
Capital employed uses book values. Hartley's folding and finishing line cost £95,000 in 2016 and is now carried at about £8,000. It is almost fully written down, so it adds very little to the annual depreciation charge. Replacing it today would cost around £130,000.
If you put the line in at replacement cost and charge a realistic depreciation charge of about £13,000 a year, capital employed rises to around £372,000, operating profit falls to about £71,000, and ROCE falls to about 19%.
Nothing about the business has changed. The ratio has just stopped rewarding it for sweating kit that will have to be replaced at some point. We see this pattern a lot in printing, manufacturing, construction and transport. A business with old fixed assets shows a lovely ROCE right up until it has to reinvest, and then the ratio falls sharply in the year of the purchase even though the business is in better shape. Capital allowances help with the tax on that purchase, but they do nothing for the accounting ratio.
3. The 2026 lease rules
For accounting periods beginning on or after 1 January 2026, the amended FRS 102 brings most leases onto the balance sheet. We cover the detail in finance lease vs operating lease.
Hartley's premises lease has five years left at £30,000 a year. Under the new rules, which apply to it from 1 July 2026, that becomes a right-of-use asset and a lease liability of about £123,000. Around £101,600 of the liability is due after more than one year, so it goes straight into capital employed.
Operating profit goes up slightly, because £30,000 of rent is replaced by about £24,600 of depreciation, with the interest part of the lease charge sitting below operating profit. So operating profit rises to about £89,400. But capital employed jumps to about £351,600.
ROCE falls from 33.6% to about 25.4%. Micro-entities using FRS 105 are not affected. Small companies using FRS 102 are, and any bonus scheme, earn-out or bank covenant that uses a return on capital measure should be looked at now.
4. Cash on the balance sheet
Hartley holds £25,000 in the bank. Many profitable owner-managed companies hold far more, sometimes several years of profit, because the owner does not want to pay the extra personal tax on extracting it. All of that cash sits in capital employed and drags ROCE down, even though it has nothing to do with how well the printing business is run. If you want to see the return on the trading business, take surplus cash out of the calculation, as in the last line of the table above.
ROCE vs ROE vs ROI
These three get mixed up all the time.
| Ratio | Formula | What it answers |
|---|---|---|
| ROCE | Operating profit ÷ capital employed | How well does the business use all its long-term funding? |
| ROE | Profit after tax ÷ equity | What are the shareholders earning on their own money? |
| ROI | Gain from an investment ÷ cost of that investment | Was this particular project, machine or campaign worth it? |
For Hartley, profit before tax is £84,000 less £11,000 of interest, which is £73,000. Corporation tax with marginal relief comes to about £15,600, leaving profit after tax of about £57,400. ROE is 57,400 ÷ 150,000, which is 38.3%.
ROE is higher than ROCE because Hartley borrows. The lenders are paid a fixed 7.5% while the capital earns 33.6%, and the difference goes to the shareholder. That is financial gearing working in the owner's favour. It also means a business can push ROE up just by borrowing more, without getting any better at what it does. ROCE is harder to game that way, which is why we prefer it for judging how well a business is actually run.
ROI is a project measure rather than a whole-business measure. You would use ROI to decide whether to buy a new press. You would use ROCE to check, a year later, whether the business as a whole is earning more on its capital because of it.
ROCE vs Other Ratios
ROCE is a profitability ratio. It works best alongside:
- the current ratio and working capital, which tell you whether the business can pay its bills in the short term
- the gearing ratio, which tells you how much of the capital employed came from lenders
- EBITDA, which strips out depreciation and is often used instead of operating profit in valuations and bank covenants
A business can have a high ROCE and still run out of cash. Profit is not cash, and a fast-growing company that ties everything up in debtors and stock can show 40% ROCE on the way to a cash flow crisis.
How ROCE Gets Gamed
Because ROCE is often used in bonus schemes and management targets, it can be pushed up without anything improving. The usual tricks:
- Putting off capital spending. The fastest way to lift ROCE is to stop investing. It works for a year or two and then the kit breaks.
- Timing the year end. Paying suppliers early or clearing the overdraft on the last day of the year changes capital employed. Using average capital employed makes this much harder.
- Selling assets and leasing them back. Before 2026 this took assets off the balance sheet and flattered ROCE. Under the new FRS 102 lease rules most of that benefit disappears, because the lease comes back on as a liability.
- Cutting maintenance. Lower costs, higher profit, same capital. Fine until the breakdown.
If you are setting targets for a management team, we would base them on average capital employed and look at ROCE alongside capital spending, so nobody is rewarded for letting the business run down.
Common Mistakes
- Using profit after interest or after tax on the top line with pre-tax capital employed on the bottom. Match them. Pre-tax profit before interest goes with capital employed that includes debt.
- Including current liabilities such as the overdraft in capital employed in an exam when the question expects the standard formula.
- Forgetting the long-term part of loans and HP. Non-current liabilities belong in capital employed.
- Comparing ROCE figures worked out differently. Check the version before you compare against a benchmark or a competitor.
- Reading one year on its own. A single ROCE figure is a snapshot. The direction over three to five years tells you much more.
How IAK Can Help
We work with limited companies, small businesses and construction companies across North London and Hertfordshire. ROCE usually comes up when an owner is deciding whether to buy a major asset, preparing a business for sale, or trying to work out whether the business is really earning more than the money would earn somewhere else.
Working out the ratio takes seconds. The useful part is deciding what belongs in capital employed, adjusting for the owner's pay and old assets, and seeing what the 2026 lease rules will do to next year's figures. That is where an accountant who knows the business adds something.
If you want ROCE and the other key ratios tracked every month, that is what management reporting is for. For year-end figures that a buyer or lender will read, see our accounting service, or get in touch to talk it through.
