How the Economic Value Added Calculator works
Economic Value Added (EVA) is a measure of residual profit: what is left over after a business pays for every source of capital it uses, not just the interest on its debt. It converts ordinary accounting profit into a value-based figure, because operating profit only counts as genuine value creation once it clears the return that lenders and shareholders require for the risk they took.
The formula
EVA is built from two pieces — net operating profit after tax (NOPAT) and a capital charge for the money used to generate it:
NOPAT = EBIT × (1 − Tax Rate)
Capital Charge = Invested Capital × WACC
EVA = NOPAT − Capital Charge
EBIT is operating profit before interest and tax, the tax rate is the effective rate applied to that profit, invested capital is the total capital — debt plus equity — tied up in operations, and WACC (weighted average cost of capital) is the blended return capital providers require.
Worked example
Take EBIT of $500,000 taxed at 25%, invested capital of $2,000,000, and a WACC of 9%. NOPAT is $500,000 × (1 − 0.25) = $375,000. The capital charge is $2,000,000 × 9% = $180,000. EVA is $375,000 − $180,000 = $195,000. Return on invested capital (NOPAT ÷ invested capital) is 18.75%, which is 9.75 percentage points above the 9% WACC — the spread that produced the positive EVA.
What moves EVA most
- Operating profit (EBIT): a direct, dollar-for-dollar driver of NOPAT and therefore EVA.
- Invested capital: more capital tied up in the business raises the capital charge, so EVA falls unless profit grows to match it — this is why EVA can flag a bloated balance sheet that accounting profit alone never would.
- WACC: a higher cost of capital — more debt, riskier equity, higher market rates — raises the bar that operating profit has to clear before any value is created.
EVA versus accounting profit
Net income and EBIT only subtract the explicit, contractual cost of debt (interest expense); they never charge for equity, even though equity investors require a return too. EVA closes that gap. A company can post a healthy, positive net income and still have negative EVA, because the accounting numbers looked fine while the return on invested capital fell short of what shareholders were owed for the risk they carried. That distinction — profitable versus profitable enough to beat the cost of capital employed — is the entire point of the metric, and it is why EVA is used inside companies to evaluate divisions, capital projects, and management performance rather than relying on net income alone.
