Return on Invested Capital (ROIC)
Return on invested capital (ROIC) is after-tax operating profit divided by the total capital invested in the business, equity and debt combined. Because the denominator includes everything financing the operations, ROIC cannot be inflated by leverage, which makes it the cleanest single measure of business quality.
The math
A company generating 180 million dollars of after-tax operating profit on 1.5 billion of invested capital earns a 12 percent ROIC. The benchmark that gives it meaning is the cost of that capital, typically 8 to 10 percent: above it, each reinvested dollar creates value; below it, growth actively destroys value while looking like progress on the revenue chart.
Debt and equity both count in the denominator.
The trap
Admiring a high ROIC without asking whether it can absorb new money. A niche business earning 30 percent on a small capital base but unable to reinvest at anything close to that rate is a lovely bond, not a compounding machine.
The pair that matters is ROIC and reinvestment: high returns on capital multiplied by the ability to deploy more capital at those returns is the actual formula behind every legendary long-term compounder.
The move
Demand a decade, not a year: sustained ROIC above 15 percent through a full cycle is statistical evidence of a moat, since competition should have eroded it. Compare ROIC to ROE to detect leverage dressing up mediocrity.
And when management announces acquisitions, watch what happens to ROIC next: it is where empire building first shows up in the numbers.
