Companies create value for shareholders only when they earn returns on invested capital that exceed the cost of that capital. This single insight — ROIC vs. WACC — underpins all of McKinsey's valuation framework and explains why two companies with identical earnings growth can have dramatically different stock market outcomes. Mastering the ROIC framework is the gateway from financial accounting to professional investment analysis.
Return on invested capital (ROIC) measures how many cents of after-tax operating profit a business generates per dollar of capital deployed — debt and equity combined. It evaluates the business independent of how it is financed, making it the cleanest measure of operating performance:
ROIC
ROIC = NOPAT ÷ Invested Capital
NOPAT = Net Operating Profit After Tax = EBIT × (1 − tax rate). Invested Capital = Operating working capital + Net PP&E + Intangibles (including goodwill) + Other long-term operating assets. Full NOPAT and IC construction is covered in Lesson 2.
ROIC vs. WACC — Economic Profit by Business Unit
WACC = 10% for all units · Economic Profit = (ROIC − WACC) × Invested Capital

McKinsey Key Insight
Woodco earns 6% ROIC — below WACC — so every dollar invested destroys value. Even though it appears profitable on the income statement, it is economically destroying capital. Foodco at 11% ROIC earns above WACC but only barely — thin economic margin of safety.
Figure 2.1 — ROIC above the WACC line (10%) creates economic profit; below it destroys value. Inspired by McKinsey Valuation: the Fred's Hardware framework for business unit performance analysis.
ROE = Net income ÷ Equity. A company that borrows heavily inflates its ROE numerically without improving its underlying business returns. A company with 6% ROIC can achieve 18% ROE by leveraging 3:1 — but the underlying business is the same. ROIC uses NOPAT (before interest, thus before the leverage benefit) and includes all capital (debt + equity). Two companies with identical ROIC but different D/E ratios have equally productive businesses — the leverage just amplifies returns for equity holders. For comparing business quality, ROIC is the correct lens. ROE is better for understanding equity returns given a specific capital structure.
The weighted average cost of capital (WACC) is the minimum return that providers of capital (debt holders + equity holders) require. Capital is not free — it has an opportunity cost. McKinsey's core thesis: value is created when a business earns returns above that opportunity cost, and destroyed when returns fall below it:
| Zone | Condition | Economic Meaning | Typical Valuation Implication |
|---|---|---|---|
| Value Creation | ROIC > WACC | Every additional dollar deployed earns more than its cost; growth is rewarded; competitive advantage is proven | Premium to book value (P/B > 1); often trades at premium multiples |
| Value Preservation | ROIC = WACC | Returns exactly cover cost of capital; zero economic profit; growth adds neither value nor destroys it | Trades near book value; multiple expansion requires ROIC improvement |
| Value Destruction | ROIC < WACC | Investing capital earns less than investors require; every dollar deployed destroys value; growth makes things worse | Discount to book value; capital should be returned to shareholders rather than reinvested |
A company with ROIC of 6% and WACC of 10% that grows revenue 20%/year is a value destruction machine — it reports growing revenues and profits but destroys 4 cents of value for every dollar it invests. This is the growth trap: management that fixates on top-line growth without regard to capital returns can report an impressive income statement while systematically destroying shareholder wealth. The only growth that creates value is growth at ROIC > WACC. Growth at ROIC < WACC should be curtailed — the capital is better returned to shareholders who can redeploy it at market rates.
Economic profit (also called EVA — Economic Value Added, a term trademarked by Stern Stewart & Co.) converts the ROIC-WACC spread into an annual dollar amount of value created or destroyed:
Economic Profit (EVA)
Economic Profit = (ROIC − WACC) × Invested Capital
Also expressible as: Economic Profit = NOPAT − (WACC × Invested Capital). The second form is intuitive: net operating profit minus the capital charge (what investors required). If NOPAT exceeds the capital charge, value was created.
Companies can be classified into four quadrants based on their ROIC level and growth rate. The quadrant determines the investment strategy:
| Quadrant | ROIC Level | Growth Rate | Strategy | Classic Examples |
|---|---|---|---|---|
| Value Compounders | High (>15%) | High (>10%) | Let it run — growth compounds value creation at high rates; this is the best possible investment profile | Amazon (2015–2021), Visa, MSFT (2016–2023) |
| Cash Machines | High (>15%) | Low (<5%) | Return capital efficiently — low reinvestment means high FCF yield; buy back shares and pay dividends rather than growing for growth's sake | Mature Berkshire subsidiaries, Philip Morris, mature Apple |
| Growth Traps | Low (<WACC) | High (>10%) | Dangerous — growth accelerates value destruction; management must improve ROIC before growing; may require business model change | WeWork (pre-collapse), many early-stage unprofitable fintechs |
| Value Traps | Low (<WACC) | Low (<5%) | Restructure or return capital — stuck in low-return, low-growth equilibrium; often industries with structural overcapacity | Many legacy retailers, commodity producers at cycle troughs |
High ROIC with moderate growth (12%) almost always outperforms high growth (25%) with low ROIC over a 10-year horizon. Why? Compound economics: a business earning 20% ROIC growing at 12% compounds capital at 20% annually on the reinvested portion, creating exponentially more value than a 25%-growth business earning 8% ROIC (below WACC). The market typically overweights growth and underweights returns on capital — creating a persistent opportunity for investors who focus on ROIC over headline earnings growth.
Key Takeaways
Company A: ROIC = 22%, WACC = 11%, Invested Capital = $600M, growing at 15%/year. Company B: ROIC = 9%, WACC = 11%, Invested Capital = $1,200M, growing at 20%/year. What is each company's annual economic profit, and which is creating value?
