The Economic Value Added calculator measures how much operating profit remains after charging a business for the capital it uses. Enter NOPAT, invested capital, and WACC to estimate economic value creation in dollars—not as a percentage.
What is Economic Value Added?
Economic Value Added (EVA) is net operating profit after tax minus a capital charge. That charge represents the return required by the providers of debt and equity capital.
A business can report an accounting profit while producing negative EVA. This happens when its operating profit is insufficient to cover the required return on invested capital. Positive EVA indicates that operating profit exceeds that requirement, based on the figures used.
How to use the EVA calculator
Use figures for the same business or project, currency, and reporting period.
- Enter NOPAT in dollars. NOPAT means net operating profit after tax. It measures operating profit after operating taxes, before financing costs. Do not substitute net income without checking for interest expense and nonoperating items.
- Enter invested capital in dollars. This is the capital committed to operating the business, financed by debt and equity—not equity alone. A common approach starts with interest-bearing debt plus equity and subtracts excess cash and other nonoperating assets.
- Enter WACC as a percentage. WACC, or weighted average cost of capital, combines the required return on equity with the after-tax cost of debt. Enter 10 for 10%, not 0.10. A loan interest rate alone is generally not a substitute for WACC.
For annual NOPAT, use an annual WACC. Choose a consistent invested-capital basis, such as beginning-of-period or average capital, especially when comparing results across years. The calculator uses the amount you enter; it does not calculate an average capital balance.
Preparing NOPAT from operating profit
If you start with EBIT, a common simplified calculation is:
NOPAT = EBIT × (1 − operating tax rate)
Use the tax rate as a decimal in this equation: for example, $200,000 × (1 − 0.25) = $150,000. EBIT is not the same as NOPAT, and neither is automatically equal to net income. Prepare this figure before entering it; the EVA calculator does not have separate EBIT or tax-rate fields.
Economic Value Added formula
The calculator applies this formula, with WACC entered as a percentage:
EVA = NOPAT − (Invested capital × WACC ÷ 100)
The amount in parentheses is the capital charge. It is the dollar return required on the invested capital for the period. Because that charge already incorporates financing costs, subtracting interest from NOPAT would generally count debt financing costs twice.
Worked example
Suppose a manufacturer has annual NOPAT of $150,000, invested capital of $1,200,000, and an annual WACC of 10%.
| Item | Amount or calculation |
|---|---|
| NOPAT | $150,000 |
| Invested capital | $1,200,000 |
| WACC | 10% |
| Capital charge | $1,200,000 × 10 ÷ 100 = $120,000 |
| Economic Value Added | $150,000 − $120,000 = $30,000 |
The manufacturer generated $30,000 above its required capital return. This is an economic profit measure, not necessarily $30,000 of additional cash available to distribute.
How to interpret your EVA result
- Positive EVA: NOPAT exceeds the capital charge. The business earned more than its estimated cost of capital during the period.
- Zero EVA: NOPAT exactly covers the capital charge. This is economic break-even, not zero accounting profit.
- Negative EVA: NOPAT falls short of the capital charge. The business did not earn its required return, even if it reported positive accounting earnings.
In the example, break-even NOPAT is $120,000. If NOPAT fell to $100,000 with capital and WACC unchanged, EVA would be −$20,000.
WACC also matters: increasing it from 10% to 12% raises the capital charge to $144,000 and reduces EVA to $6,000. When the appropriate WACC is uncertain, test a reasonable range rather than treating one estimate as exact.
Using EVA in business decisions
- Track operating performance. Compare periods using consistent definitions to see whether higher profits are keeping pace with the capital needed to generate them.
- Evaluate an expansion. Compare expected additional NOPAT with the charge on additional capital. An extra $20,000 of annual NOPAT from $250,000 of capital at 10% WACC produces incremental EVA of −$5,000.
- Assess capital efficiency. Identify opportunities to reduce idle assets, excess inventory, or unnecessary capital commitments without harming sustainable operating profit.
- Test a business plan. Model different profit, capital, and financing assumptions to understand what must improve for EVA to become positive.
Strengths and limitations
EVA makes the cost of both debt and equity visible, which is particularly useful when evaluating capital-intensive operations. However, its reliability depends on the quality of NOPAT, invested capital, and WACC estimates.
Accounting treatment can also affect comparisons. For example, expensing research or development costs may make an intangible-heavy business look different from one whose investments appear as assets. This calculator applies the basic formula to your inputs; it does not make accounting adjustments.
A single period's negative EVA does not prove that a long-term investment should be abandoned. Early investment costs and later benefits can fall in different periods. Review forecasts, cash flows, and risk alongside the result.
EVA versus related return measures
Unlike ROI, ROIC, and ROCE, EVA is a dollar amount rather than a percentage. Larger companies may generate more EVA simply because they employ more capital, so absolute EVA alone is not a fair ranking of businesses of different sizes.
ROIC is particularly useful alongside EVA. When ROIC is defined as NOPAT divided by the same invested-capital amount, ROIC above WACC corresponds to positive EVA. Use EVA to assess the amount of value created and ROIC to assess capital efficiency.
