What is Economic Value Added (EVA) Mechanics?
Mathematical Foundation
Laws & Principles
- The Capital Charge Law: If you give a CEO $100 Million, and they generate $1 Million in accounting profit, standard accountants will celebrate the 'profitable' year. EVA violently disagrees. If the investors required an 8% return (WACC), the CEO was mathematically required to generate $8 Million. Their $1 Million 'profit' actually destroyed $7 Million of true economic wealth.
- The Positive Spread Execution: A company only creates true, lasting enterprise value when its Return on Invested Capital (ROIC) mathematically exceeds its WACC. If a company exists in a permanent negative spread, growing the company actually accelerates wealth destruction.
Step-by-Step Example Walkthrough
" A legacy retail corporation holds $500 Million in Total Capital (real estate and inventory). Investors demand a 10% WACC. The CEO reports proudly that they achieved $30 Million in NOPAT this year. "
- Identify NOPAT: $30,000,000.
- Calculate the Capital Charge: $500,000,000 (Capital) × 10% (WACC) = $50,000,000.
- Execute the EVA Equation: $30,000,000 - $50,000,000 = -$20,000,000.
