Economic value added (EVA)
When and how should economic value added (eva) be applied?
Contents
Helps managers answer: How well are we delivering value to our shareholders?
Economic Value Added, or EVA, estimates economic profit by subtracting the full cost of financing operating capital from after-tax operating profit. Stern Stewart developed the branded methodology to make the opportunity cost of debt and equity visible in internal decisions.
When to use it
- Answer the key performance question: “How well are we delivering value to our shareholders?”
- Assess this KPI within the Financial perspective.
- Plan data collection, formula use, reporting frequency, and data-source requirements for this KPI.
- Compare results against the targets, benchmarks, examples, or trend guidance available for this KPI.
Origins
Economic profit descends from classical economics and the accounting idea of residual income. Joel Stern and G. Bennett Stewart adapted that lineage through Stern Stewart & Co., founded in nineteen eighty-two, defining accounting adjustments and trademarking Economic Value Added. The method asks whether NOPAT exceeds a charge for every dollar of operating capital.
What it is
Perspective: Financial perspective.
Key performance question: How well are we delivering value to our shareholders?
EVA can operate as a governance and investment measure: managers are expected to improve operating returns while recognising that capital is scarce and carries an opportunity cost.
The method often adjusts conventional accounting where treatment obscures economic investment. Research, development or training may be capitalised and amortised when they create multi-period benefits. The objective is not to manufacture a better result, but to improve the match between measured profit and the capital that produced it.
Debt and equity both belong in the capital base. Investors could place funds in bonds, deposits or other equities, so a company creates economic profit only after compensating them for the return available elsewhere at comparable risk.
Some organisations connect incentives to improvement in EVA through a bonus bank. A declared award is deposited, part is paid and the balance remains at risk against later performance. This design can reward a business unit for improving a negative EVA while withholding reward when a positive result deteriorates. It aims to align managers with investors across more than one reporting period.
How to use it
Measurement
Data collection method
Start with the income statement and operating balance sheet, calculate the capital charge and apply only documented adjustments that improve economic comparability.
Formula
EVA = NOPAT − (C × K)
Where:
- NOPAT is net operating profit after tax
- C is WACC, the average required return paid to debt and equity holders
- K is economic capital employed
Estimate the cost of equity with an appropriate method such as CAPM. In simplified form, expected equity return equals a future risk-free return plus beta multiplied by the general equity risk premium.
With a risk-free rate of 7%, beta of 1.1 and equity risk premium of 4%, cost of equity is:
7% + (1.1 × 4%) = 11.4%.
Estimate debt cost from the yield required by lenders and express it after tax where the tax shield applies:
After-tax debt cost = before-tax debt cost × (100 − marginal tax rate).
Frequency
Calculate EVA monthly when it supports operational management; refresh WACC annually or whenever market conditions or capital structure change materially.
Source of the data
Use profit-and-loss, balance-sheet and financing data reconciled to the accounting system.
Cost/effort in collecting the data
A basic calculation is inexpensive when inputs already exist. Cost rises when missing operating-capital data must be collected or numerous accounting adjustments must be governed. Complexity should remain proportionate to the decision value.
Target setting/benchmarks
Compare EVA and EVA improvement with companies or units of similar risk, capital intensity and accounting policy. Absolute EVA also reflects scale, so interpret it with a return measure and the capital invested.
Example
A household-furniture company used EVA to evaluate a packaging-line investment in a case reported in Building and Communicating Shareholder Value in 2000:
The new line would expand packaging capability, add sales and lower packaging cost, increasing NOPAT by £2.0 million. It requires £7.5 million of additional operating capital. At an 11% cost of capital, the economic effect is:
Increase in NOPAT: 2 million pounds
Less capital charge, 11% of £7.5m: £0.8m
Economic value added: £1.2m
The investment therefore creates economic value under the stated forecasts, but the decision should still test volume, savings and execution risk.
Top practical tip
Treat EVA implementation as a management-system change, not a new spreadsheet. Teach teams how operating choices affect NOPAT and capital, reconcile the measure to accounts and align incentives with sustained improvement rather than one-period extraction.
Top pitfall
Accounting adjustments can make EVA opaque, while a simplified version may omit meaningful economic differences. More importantly, a high hurdle can discourage uncertain but valuable growth. Pair EVA with explicit risk appetite and multi-period strategic analysis.
