Formula
Capital Charge = Invested Capital × WACC
EVA = NOPAT − Capital Charge
Where NOPAT = Operating Income × (1 − Tax Rate)
How it works
Economic Value Added (EVA), developed by Stern Stewart & Co., measures the dollar value generated above the cost of financing the capital deployed. NOPAT (Net Operating Profit After Tax) represents the after-tax operating earnings available to all capital providers. The capital charge — invested capital multiplied by the WACC — represents the minimum return required by both debt and equity holders. When NOPAT exceeds the capital charge, EVA is positive and the company creates shareholder value; when NOPAT falls short, EVA is negative and value is destroyed even if accounting earnings are positive.
Worked example
EVA for a capital-intensive business
- NOPAT = $2,000,000; Invested Capital = $12,000,000; WACC = 10%
- Capital Charge = $12,000,000 × 10% = $1,200,000
- EVA = $2,000,000 − $1,200,000 = $800,000
EVA = $800,000 (value-creating)
Common mistakes to avoid
- Using reported operating income directly as NOPAT without applying the tax adjustment — NOPAT = Operating Income x (1 - Tax Rate), and skipping this step overstates EVA.
- Including non-operating assets (excess cash, investments unrelated to operations) in invested capital, which inflates the capital charge and understates EVA.
- Treating a positive EVA as sufficient without considering the capital base — a small positive EVA on a massive capital base may indicate poor returns that should be redeployed.
Key terms
- What is NOPAT?
- Net Operating Profit After Tax (NOPAT) is operating income multiplied by (1 minus the effective tax rate). It represents after-tax operating profit available to all capital providers, before the effects of financing.
- What is the capital charge in EVA?
- The capital charge is invested capital multiplied by the WACC. It is the minimum dollar return that debt and equity investors require for committing capital to the firm.
- What is WACC?
- Weighted Average Cost of Capital (WACC) is the blended required rate of return across a company's debt and equity, weighted by their proportions in the capital structure.
- How is EVA used by management?
- EVA is used as an internal performance measure and compensation benchmark. Divisions that consistently generate positive EVA are considered value-creators; negative EVA signals capital misallocation.
- Who created EVA?
- EVA was trademarked and popularized by the consulting firm Stern Stewart & Co. in the late 1980s as a refinement of the residual income concept.
Frequently asked questions
- How does EVA differ from net income?
- Net income deducts interest (cost of debt) but not the cost of equity. EVA deducts a charge for all invested capital at the weighted average cost of capital, making it a more complete profitability measure.
- What does a negative EVA indicate?
- A negative EVA means the company is earning less on its invested capital than investors require, effectively destroying shareholder value even if accounting earnings are positive.
- Why do companies use EVA for management compensation?
- Tying bonuses to EVA incentivizes managers to invest only in projects that earn above the cost of capital, discouraging empire-building and over-investment in low-return assets.
