Return on invested capital (ROIC)
After-tax operating profit divided by the debt and equity invested in operations: a measure of returns that is neutral to financing.
Return on invested capital (ROIC) measures how much after-tax operating profit a company generates on all the capital invested in its operations, from both lenders and shareholders. Because it counts debt and equity together, it is not inflated by leverage the way return on equity can be. Many investors regard it as the clearest test of whether a business creates value: if ROIC exceeds the cost of capital, growth adds value; if not, growth destroys it.
How it works
NOPAT, net operating profit after taxes, is the profit the business would earn if it had no debt. Practitioners differ on details, such as whether to subtract all cash or only "excess" cash, and whether to add back leases or capitalized R&D, so ROIC figures from different sources rarely match exactly.
How to read it
- The spread matters most. ROIC minus the cost of capital tells you whether reinvestment is worthwhile. A company earning 25% on capital that can keep reinvesting at that rate is far more valuable than one earning 9% against an 8% cost.
- Durability. A high ROIC sustained for a decade often signals a competitive advantage, such as a strong brand, network effects or low costs.
- Incremental returns. The return on new capital, the change in NOPAT divided by the change in invested capital, can differ sharply from the average.
Limits to keep in mind
Intangible investments such as R&D and brand-building are expensed, not capitalized, so they are missing from invested capital, which can overstate ROIC for technology and consumer companies. Acquisitions add goodwill, which tends to pull ROIC down even when the deal is sound.
