All of valuation reduces to three variables: the cash flows a business generates, the rate at which those cash flows grow, and the risk embedded in both. McKinsey's core finding — presented in Chapter 4 of Valuation — is that ROIC and growth together explain the overwhelming majority of differences in enterprise value across companies. Businesses that earn high returns on invested capital and grow efficiently create value. Businesses that grow but earn below their cost of capital destroy it.
The Three Value Drivers — McKinsey's Key Value Driver Formula
All business value ultimately traces back to these three variables
McKinsey Key Value Driver Formula
EV = NOPAT × (1 − g/ROIC) / (WACC − g)
Where (1 − g/ROIC) is the free cash flow margin and (WACC − g) is the discount spread
Value Creator
ROIC >> WACC: every $ reinvested creates value
Value Neutral
ROIC = WACC: growth creates no incremental value
Value Destroyer
ROIC < WACC: growth actually destroys value
ROIC–WACC Spread: The Single Most Important Number
| Spread (ROIC − WACC) | Effect of Growth | Value Driver | Example Companies |
|---|---|---|---|
| +15% or more | Growth massively creates value | Maximize reinvestment rate | Visa, Mastercard, MSFT |
| +5% to +15% | Growth creates moderate value | Reinvest selectively; return excess cash | Most S&P 500 leaders |
| Near 0% | Growth is value-neutral | Don't grow for growth's sake | Mature industrials, utilities |
| Negative | Growth destroys value | Shrink, restructure, or exit | Capital-misallocating conglomerates |

McKinsey's empirical research across thousands of companies over decades produces a consistent finding: the value of any business is determined by three and only three fundamental variables. Every ratio, multiple, and model used in practice is ultimately a shorthand for estimating one or more of these three drivers. Understanding them directly — rather than through the shorthand — produces more insight per unit of analysis.
McKinsey's foundational empirical observation: companies that sustain high ROIC and grow create value for shareholders far exceeding those that simply grow (without ROIC discipline) or maintain ROIC (without growth). The combination is multiplicative, not additive. A business with 25% ROIC that grows at 8% is worth dramatically more than a business with 8% ROIC that also grows at 8% — even though both grow at the same rate. ROIC is the quality of growth; growth is the quantity. Value creation requires both.
McKinsey derives the key value driver formula from first principles by combining the DCF perpetuity approach with the economic definition of free cash flow. The result is elegant: value is a function of operating profit, ROIC, growth, and the cost of capital — with no other variables required at the enterprise level:
McKinsey Key Value Driver Formula
Enterprise Value = NOPAT × (1 − g/ROIC) / (WACC − g)
NOPAT = Net Operating Profit After Tax; g = sustainable growth rate; ROIC = Return on Invested Capital; WACC = Weighted Average Cost of Capital
| ROIC | Growth Rate (g) | 1 − g/ROIC | WACC − g | Enterprise Value |
|---|---|---|---|---|
| 15% | 5% | 0.667 | 0.050 | $100M × 0.667/0.050 = $1,333M |
| 15% | 8% | 0.467 | 0.020 | $100M × 0.467/0.020 = $2,333M |
| 10% (= WACC) | 5% | 0.500 | 0.050 | $100M × 0.500/0.050 = $1,000M |
| 10% (= WACC) | 8% | 0.200 | 0.020 | $100M × 0.200/0.020 = $1,000M |
| 7% (< WACC) | 5% | 0.286 | 0.050 | $100M × 0.286/0.050 = $571M |
| 7% (< WACC) | 8% | −0.143 | 0.020 | $100M × (−0.143)/0.020 = −$714M (growth destroys value!) |
When ROIC = WACC (10% in the example), growth does not change enterprise value — from $1,000M at 5% growth to $1,000M at 8% growth. This is the central insight: growth only creates value when ROIC > WACC. Below WACC, growth actively destroys value — as shown in the bottom row, where aggressive growth at 8% for a business earning 7% ROIC produces a negative (mathematically: value-destroying) enterprise value implication. Many companies 'grow' into lower valuations precisely because they are investing capital at below-cost returns.
The ROIC-WACC spread (ROIC minus WACC) is the single most important metric in corporate finance. It tells you whether each incremental dollar invested in the business creates or destroys value for shareholders. Economic profit — the dollar version of the spread — captures this directly:
Economic Profit (EP)
Economic Profit = Invested Capital × (ROIC − WACC)
Positive EP = value creation; zero EP = breakeven; negative EP = value destruction
| ROIC-WACC Spread | Archetype | Real-World Examples | Value Creation Implication |
|---|---|---|---|
| >15% spread | Dominant franchise | Visa, Mastercard, Google (Alphabet), LVMH | Every dollar of growth creates enormous value; capital is precious; protect the moat |
| 5–15% spread | Strong competitive position | Apple, Microsoft, Amazon, quality industrials | Growth creates significant value; reinvestment is warranted; manage capital allocation carefully |
| 0–5% spread | Average business | Most mature industries, commoditized businesses | Growth creates modest value; prioritize capital efficiency; return excess capital to shareholders |
| Near zero (ROIC ≈ WACC) | Value-neutral | Highly competitive industries approaching equilibrium | Indifferent between investing and returning capital; growth is a wash |
| Negative spread (ROIC < WACC) | Value-destroying | Airlines (historically), telecom infrastructure, capital-intensive retailers | Growth actively destroys value; should shrink, restructure, or return capital rather than invest |
Visa and Delta Air Lines both grow revenue at ~7–10% annually. Visa earns ~40% ROIC on minimal invested capital (its business is software and brand — almost no physical capital required). Delta earns ~8% ROIC on massive invested capital (planes, gates, maintenance facilities). With a WACC of roughly 9% for both: Visa's ROIC-WACC spread ≈ +31%; Delta's spread ≈ −1%. Visa's growth creates enormous value; Delta's growth at best breaks even. This explains why Visa trades at 30× earnings and Delta at 6× — not because investors arbitrarily prefer Visa, but because Visa's capital structure and competitive dynamics create far more value per dollar of growth.
A common source of confusion in fundamental analysis: companies with the highest accounting earnings are not necessarily the most valuable. What matters is free cash flow — earnings after the reinvestment required to generate future growth. High-growth companies often show low or negative free cash flow precisely because they are reinvesting aggressively for future value:
Reinvestment Rate Identity
Reinvestment Rate = g / ROIC
Free Cash Flow = NOPAT × (1 − Reinvestment Rate) = NOPAT × (1 − g/ROIC)
Key Takeaways
Company A earns $100M NOPAT, has a 20% ROIC, grows at 5%, and a 10% WACC. Company B also earns $100M NOPAT, has a 12% ROIC, grows at 5%, with the same 10% WACC. Which is more valuable and by how much?
