What is ROIC, and why it matters more than growth
Growth is only good if the business earns more on the money it invests than that money costs. ROIC is how you check.
Two companies each grow revenue 12% a year for a decade. One makes its owners wealthy. The other quietly destroys capital the entire time. The difference is not on the income statement — it is in what each business had to spend to achieve that growth.
Return on invested capital is the single number that separates them.
The calculation
ROIC divides operating profit after tax by the capital the business has tied up in operations — roughly debt plus equity, less cash that is not needed to run the company.
Why it beats growth as a first filter
Growth tells you the business is getting bigger. ROIC tells you whether getting bigger is worth doing. A company earning below its cost of capital and reinvesting heavily is converting shareholder money into a larger, less profitable version of itself.
This is why the 8 Pillars set the ROIC threshold at 9%. It is not a precise cost of capital for any specific business — it is a floor that filters out companies where growth is unlikely to compound in the owner's favour.
What good looks like
Where ROIC misleads
- Asset-light businesses can post enormous ROIC simply because the denominator is small. High is not automatically better — check whether the business can absorb more capital at that rate.
- Acquisitive companies carry large goodwill balances, which inflates invested capital and understates the return on the operating business.
- Companies mid-investment show depressed ROIC while a factory or a data centre is being built and before it earns anything.
- A single year is noise. Average five, which is why the pillar does.
None of these make ROIC less useful. They make it a starting question rather than a verdict — which is true of every pillar.
Common questions
What is the difference between ROIC and ROE?
Return on equity measures profit against shareholders' capital alone, so it can be flattered by borrowing. ROIC includes debt in the denominator, which makes it a cleaner read on how well the underlying business converts capital into profit regardless of how it is financed.
Is a high ROIC always good?
Not on its own. A very high ROIC on a small capital base is less valuable than a good ROIC on a base the company can keep growing. What matters is the return AND how much capital can be deployed at it.
