What it is
Return on invested capital measures how much after-tax operating profit a company generates relative to the total capital, both debt and equity, that funds its operations. It uses NOPAT (net operating profit after tax) over invested capital, so it captures the productivity of the whole capital base regardless of financing mix. ROIC is widely regarded as one of the cleanest measures of how well a company turns capital into profit.
Why it matters
ROIC matters most when compared to a company's cost of capital (WACC): a business creates value only when ROIC exceeds the cost of the capital it uses, and destroys value when it does not. A durable, high ROIC is a strong sign of a competitive moat. The main pitfalls are that invested capital can be defined several ways and that goodwill from acquisitions can distort the figure, so consistency in calculation matters.
How it's calculated
Divide net operating profit after tax (NOPAT, roughly operating income times one minus the tax rate) by invested capital, which is total debt plus equity less excess cash.
How Quintarthai uses it
ROIC is part of the profitability ratios on a company's deep-analysis page and feeds Quinn's quality and moat assessment, where every figure carries a click-to-source provenance receipt.
Cross-border note. Definitions of invested capital depend on balance-sheet classifications that differ between IFRS and US GAAP (notably leases and intangibles), so cross-border ROIC comparisons are most reliable when the same calculation method is applied to both.
FAQ
What does it mean if ROIC is above the cost of capital?
It means the company earns more on its invested capital than that capital costs, so it is creating value for investors. When ROIC falls below the cost of capital, growth can actually destroy value.
How is ROIC different from ROE?
ROE measures return on shareholders' equity only and is affected by debt, while ROIC measures return on all invested capital (debt and equity) using after-tax operating profit, so it is less distorted by leverage.
Check your understanding
Under what condition does a company create value with the capital invested in its business?
A business creates value only when ROIC is greater than the cost of the capital it uses, and growth can actually destroy value when ROIC falls below the cost of capital.
