McKinsey's most important empirical insight: return on invested capital — specifically the spread between ROIC and the cost of capital — explains more of the variation in enterprise value multiples than any other single variable. Growth is only a value driver when ROIC exceeds WACC; below that threshold, growth actively destroys value. Understanding this relationship is the difference between a mechanical model-builder and an analyst who understands what drives business value.
| ROIC | g | WACC | EV/NOPAT | Interpretation |
|---|---|---|---|---|
| 25% | 3% | 10% | 16.0× | Premium: high ROIC compounds value |
| 15% | 3% | 10% | 14.0× | Above-average business |
| 10% | 3% | 10% | 10.0× | Neutral: ROIC = WACC, growth irrelevant |
| 8% | 3% | 10% | 8.6× | Below-average: growth destroys value |
| 6% | 3% | 10% | 7.1× | Growth accelerates value destruction |
Return on Invested Capital (ROIC) is the rate at which a business converts invested capital into after-tax operating profit. McKinsey's empirical research shows that ROIC, more than any other single metric, explains the long-run multiple at which businesses trade. The reason is mathematical: the Key Value Driver Formula shows that enterprise value is a direct function of ROIC relative to WACC — a company with ROIC twice its WACC is worth dramatically more than an identical business earning ROIC equal to its WACC, even with the same growth rate.
ROIC Decomposition
ROIC = NOPAT / Invested Capital = (NOPAT / Revenue) × (Revenue / Invested Capital) = NOPAT Margin × Capital Turnover
Every improvement in ROIC comes from either higher NOPAT margins, higher capital efficiency, or both
| ROIC Driver | Formula | What Drives It | Management Lever |
|---|---|---|---|
| NOPAT Margin | NOPAT / Revenue | Revenue mix, pricing power, cost structure, operating leverage, tax efficiency | Pricing strategy, cost reduction programs, product mix optimization, tax planning |
| Capital Turnover | Revenue / Invested Capital | Asset intensity, working capital efficiency, capacity utilization, lease vs. own decisions | Working capital reduction (faster AR collection, slower AP, leaner inventory), capex discipline, asset-light business models |
| Gross Margin | Gross Profit / Revenue | Pricing power vs. input costs; differentiation protecting price premium | Brand investment, product quality, supplier negotiation, hedging input costs |
| SG&A Ratio | SG&A / Revenue | Operational leverage as revenue grows; organizational efficiency; R&D classification | Headcount management, sales productivity improvement, administrative rationalization |
| Effective Tax Rate | Tax Expense / Pre-tax Income | Tax planning, jurisdictional mix, transfer pricing, tax credits and deferrals | R&D tax credits, geographic income allocation, structuring deductible expenses |
| Days Sales Outstanding (DSO) | AR / Revenue × 365 | Customer payment terms, collection effectiveness, credit quality of customer base | Tighter credit terms, factoring, early payment discounts, collections process improvement |
| Inventory Turns | COGS / Inventory | Supply chain efficiency, demand forecasting accuracy, product complexity | Just-in-time inventory, SKU rationalization, demand planning systems, supplier lead time reduction |
| Days Payable Outstanding (DPO) | AP / COGS × 365 | Supplier payment terms, negotiating leverage, supply chain financing | Extended payment terms, supply chain financing programs, supplier concentration analysis |
The most counterintuitive insight in business valuation: growth is not always valuable. Growth that earns a return below the cost of capital destroys value — every dollar reinvested returns less than a dollar of present value. This is not a niche observation; McKinsey finds that many large corporations have grown profitably in accounting terms while destroying shareholder value by investing at ROIC below WACC for extended periods.
| Scenario | NOPAT | ROIC | WACC | Growth | Reinvestment Rate | FCFF | Enterprise Value | EV/NOPAT |
|---|---|---|---|---|---|---|---|---|
| Value creator (high ROIC) | $100M | 25% | 10% | 10% | 40% | $60M | $600M | 6.0× |
| Value creator (moderate ROIC) | $100M | 15% | 10% | 10% | 67% | $33M | $333M | 3.3× |
| Value neutral (ROIC = WACC) | $100M | 10% | 10% | 10% | 100% | $0M | $1,000M* | 10× |
| Value destroyer (ROIC < WACC) | $100M | 7% | 10% | 10% | 143% | −$43M | <$1,000M | <10× |
| No growth, high ROIC | $100M | 25% | 10% | 0% | 0% | $100M | $1,000M | 10× |
When ROIC = WACC, enterprise value = NOPAT / WACC regardless of the growth rate. A company growing at 15% with ROIC = WACC is worth exactly the same as the identical company with 0% growth. This is the most important insight for corporate strategy: investing in growth only creates value when ROIC > WACC. This is why McKinsey argues that management teams should first ask 'what is our ROIC vs. WACC?' before committing to growth programs. Note: The value-neutral case with 10% growth requires reinvestment rate = 100%, meaning the company retains all earnings to fund growth — producing $0 free cash flow. The $1,000M value comes entirely from the terminal value after growth eventually slows.
Key Value Driver Formula
EV = NOPAT × (1 − g/ROIC) / (WACC − g)
Where (1 − g/ROIC) is the free cash flow margin — the fraction of NOPAT not consumed by reinvestment. When ROIC → WACC, EV → NOPAT/WACC regardless of g (growth rate cancels out)
Once you understand the ROIC tree, you can quantify the value impact of operational improvements. The leverage of different ROIC levers varies significantly by business type and starting position. McKinsey's guidance on value improvement priorities:
| ROIC / Growth Rate | 0% Growth | 5% Growth | 10% Growth | 15% Growth |
|---|---|---|---|---|
| ROIC = 8% (below WACC) | $1,000M | $800M | $500M | $200M |
| ROIC = 10% (= WACC) | $1,000M | $1,000M | $1,000M | $1,000M |
| ROIC = 15% | $1,000M | $1,333M | $2,000M | $4,000M |
| ROIC = 25% | $1,000M | $1,500M | $3,000M | → ∞ as g → WACC |
McKinsey's research team analyzed thousands of companies over multiple decades to test whether ROIC actually explains the valuation multiples investors pay. The results are unambiguous and form the empirical core of the firm's valuation philosophy:
For a long-term investor, the most important question is not 'what is the current ROIC?' but 'how long can this ROIC persist above WACC?' A company with 20% ROIC that will revert to 10% in 3 years is worth far less than a company with 20% ROIC that will sustain it for 15 years. The explicit forecast period in a DCF model exists precisely to capture this ROIC persistence before the terminal value assumes convergence. Buffett's competitive moat analysis is, at its core, a ROIC persistence analysis.
Key Takeaways
Company A: NOPAT = $80M, ROIC = 20%, growth = 8%, WACC = 10%. Company B: NOPAT = $80M, ROIC = 11%, growth = 8%, WACC = 10%. Calculate both enterprise values and explain the multiple difference.
