What is ROIC and why is it one of the most valued quality metrics?

ROIC (Return On Invested Capital) answers one of the most important questions you can ask about a business: how much profit does it generate for every euro of capital it puts to work? It is one of the most valued indicators for assessing a company’s quality.

How it is calculated

ROIC divides net operating profit after tax (NOPAT) by invested capital, which is the sum of debt and equity employed in the business. The result is expressed as a percentage. A 15% ROIC means the company generates 15 cents of operating profit for every euro of invested capital.

Why it matters so much

A company only creates value when its ROIC consistently exceeds its cost of capital (what it costs to finance itself). If a company earns a 20% ROIC and its cost of capital is 8%, every reinvested euro multiplies shareholder value. If the opposite is true, growing destroys value.

A high, stable ROIC over many years is also often a sign of a durable competitive advantage: a strong brand, low costs, network effects or barriers to entry. It is hard to keep earning high returns if competitors can easily copy you.

What to look at when interpreting it

• Level: above 10-15% is usually good; above 20%, excellent.
• Consistency: a stable ROIC over several years is worth more than an isolated peak.
• Trend: is it improving or deteriorating? Direction matters as much as level.
• Sector: capital-intensive businesses (heavy industry, telecom) tend to have lower ROIC than software or services.
