Return on invested capital (ROIC)

ROIC shows how much profit a company earns on the money invested in it. Why it is the best single test of a moat, and how it compares with ROE.

What it measures

Return on invested capital is the after-tax operating profit a company earns for every dollar of capital put into the business, from both shareholders and lenders.

ROIC = net operating profit after tax (NOPAT) / (debt + equity - excess cash)

A company with 20% ROIC turns $100 of invested capital into $20 of yearly operating profit.

Why it matters

Growth only creates value when the money reinvested earns more than it costs. The cost of capital for most companies is around 8 to 10% a year.

  • ROIC well above the cost of capital: every dollar reinvested creates value. Growth is good.
  • ROIC near the cost of capital: growth adds size, not value.
  • ROIC below it: growth destroys value.

A high ROIC sustained for many years is one of the strongest signs of an economic moat. Without a moat, competitors would copy the business and push returns down.

ROIC versus ROE

Return on equity (net income / shareholders' equity) is easier to find but can be flattered by debt: a company that borrows heavily and buys back shares shrinks its equity and inflates ROE. ROIC counts debt as invested capital too, so it is harder to game. See Debt-to-equity ratio.

Readings

ROIC Reading
Above 20% Exceptional
15% to 20% Strong
8% to 15% Around the cost of capital
Below 8% Weak

Caveats

  • Large acquisitions add goodwill to invested capital and lower ROIC for years.
  • Asset-light businesses (software) naturally show high ROIC; compare within an industry.
  • Definitions vary between data providers.
