Does a high return on capital really create value?

A high return on capital means nothing on its own: it must exceed what that capital costs the company, the blend of what shareholders demand and what lenders charge, to truly create value. A company earning 8% on invested capital while that capital costs it 10% destroys value, even though 8% sounds good in absolute terms. Here is how I apply this test.
The number that feels good, but can lie
Return on invested capital, what a company generates each year in cash for every dollar put into its business, is one of my favorite criteria. The higher it is, the harder the money reinvested in the business is working. The problem is that a high number in absolute terms says nothing on its own: 8% return on capital is excellent for some companies and frankly disappointing for others.
The real test: beating the cost of capital
A company does not fund its operations by magic. It uses shareholder money, which expects a certain return in exchange for the risk taken, and sometimes debt, on which it pays interest. The blend of the two has a cost, called the cost of capital. For a large stable company, that cost typically runs between 8 and 12% a year depending on sector and perceived risk. The test that really matters is not 'is the return on capital high?' but 'does the return on capital beat what that capital costs the company?'. If yes, every dollar reinvested creates value. If no, the company destroys value even while reinvesting in its own growth.
A concrete example with 5 companies I screened
Look at the gap between these returns on capital, all measured this week on real files from my filter: Palo Alto Networks at 17.1%, Yelp at 38.3%, Vertiv at 54.4%, Fortinet at 73.6%, Powell Industries at 91.7%. Even the lowest of these five, 17.1%, comfortably beats a typical cost of capital of 8 to 12%. All five companies create value on this criterion. But the gap between 17.1% and 91.7% tells a different story: the wider the margin above the cost of capital, the more every reinvested dollar counts.
| Company | Return on invested capital |
|---|---|
| Powell Industries (POWL) | 91.7% |
| Fortinet (FTNT) | 73.6% |
| Vertiv (VRT) | 54.4% |
| Yelp (YELP) | 38.3% |
| Palo Alto Networks (PANW) | 17.1% |
Where the test really matters: capital heavy sectors
The test gets far more interesting in sectors that need enormous amounts of capital to operate: electric utilities, pipelines, heavy infrastructure. These companies often show a return on capital close to their cost of capital, sometimes barely above it. A company like that can be perfectly well run, profitable, useful, and still create very little net value for its shareholders once the cost of capital is subtracted. It is not a bad business, it is a structurally capital intensive one where the margin for maneuver is narrower.
Why I never look at this criterion alone
A high return on capital combined with strong sales growth is the signal of a true compounding machine: the company keeps finding new opportunities to reinvest at a high return, and every dollar of retained earnings is worth several more tomorrow. Fortinet and Powell Industries, with returns of 73.6% and 91.7% combined with 18 to 26% a year sales growth, illustrate this dynamic well. Conversely, a high return on capital with no growth opportunity should push a company to return cash to shareholders, through buybacks or dividends, rather than reinvest for the sake of it.
How I use this test day to day
I do not compute a precise, custom cost of capital for every single company, that would be false precision given the fragile assumptions it requires. I use it instead as a common sense filter: a return on capital comfortably above the typical 8 to 12% range passes the test. Below it, or barely within it, I look much more closely at whether the company truly creates value by reinvesting, or would be better off returning cash to shareholders.

- A high return on capital means nothing on its own: it must beat the company's cost of capital to truly create value.
- The cost of capital for a large stable company typically runs between 8 and 12% a year depending on sector and perceived risk.
- Real example: Powell Industries (91.7%), Fortinet (73.6%) and Vertiv (54.4%) beat that range by a wide margin; even Palo Alto Networks, the lowest of the group at 17.1%, already comfortably clears it.
- Capital intensive sectors (utilities, heavy infrastructure) often show a return close to their cost of capital, mechanically limiting net value creation.
- A high return combined with strong growth signals a true compounding machine; without growth opportunities, cash is better returned to shareholders than reinvested at any cost.
FAQ
What is the cost of capital?
The blend of what shareholders expect as a return for the risk taken, and what the company's debt interest costs. For a large stable company, it typically runs between 8 and 12% a year.
Is a 15% return on capital always good?
It depends on the company's cost of capital. If that cost is 10%, 15% creates value. If the sector is very capital intensive and the real cost is closer to 14%, the margin of value creation becomes much thinner.
Why do capital intensive companies often create less value?
Because they need enormous amounts of capital to operate, plants, infrastructure, networks, which mechanically brings their return on capital closer to its cost, leaving a narrower margin of value creation than a lighter, less capital hungry business.
Should you avoid companies with a low return on capital?
Not automatically, but they deserve closer scrutiny to check whether they truly create value by reinvesting. This is not investment advice: do your own research.

Written by Lubin Danilo, founder of Lubin Investment. A self-taught individual investor, I find fundamental analysis fascinating, and it has delivered excellent results. For three years now, my performance has beaten the S&P 500. But analyzing every stock took too much time: sites with incomplete data, calculation methods and criteria never aligned with mine. And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me. It judges a company's quality and its price separately, using criteria drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran).
