Return on Invested Capital (ROIC)

Return on invested capital measures the after-tax operating profit a company earns on every dollar tied up in the business: NOPAT (net operating profit after tax) divided by invested capital, meaning the sum of debt and equity actually deployed in operations. Unlike return on equity, it cannot be juiced with leverage — borrowing more grows both profit and the capital base it is measured against.

The number only means something next to the company's cost of capital. A business earning 18% ROIC against a 9% WACC creates a dollar of value with every dollar it reinvests; one earning 6% against the same 9% destroys value even while reporting growing profits. This spread is why quality investors treat sustained high ROIC as the signature of a moat — competition is supposed to grind returns down toward the cost of capital, and a company that holds 20%+ for a decade is winning a fight most companies lose.

The trap is in the denominator. Invested capital can be computed with or without goodwill, and the choice changes the story: excluding goodwill shows how good the underlying business is, including it shows whether management's acquisitions earned their price. A roll-up can post a brilliant ex-goodwill ROIC while destroying value on every deal.
