Economic value added: NOPAT minus the capital charge
Calculate EVA from NOPAT, invested capital, and WACC, then distinguish it from ROI, residual income, and project NPV.
The decision that earns the point
Define the business decision and required output
Economic value added measures operating profit after charging the business for the capital it uses. In its common exam form, EVA equals net operating profit after tax minus invested capital multiplied by the weighted average cost of capital. Positive EVA means the period's NOPAT exceeded the required capital charge under the stated measurements and adjustments.
Exam use
BAR can ask candidates to calculate NOPAT, invested capital, the capital charge, and EVA or interpret why EVA changes when profit, capital intensity, or WACC changes.
Your scratch-paper plan
Solve it in three moves
- 1
Measure operating profit
Start from the supplied operating result, apply the stated tax treatment, and exclude financing items when calculating NOPAT.
ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC - 2
Define invested capital
Use the operating assets and funding base specified by the task, applying only the stated accounting adjustments.
ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC - 3
Apply the capital charge
Multiply compatible invested capital and WACC measures, then subtract the charge from NOPAT and interpret the sign.

Worked problem
Work the facts before choosing the answer
A division reports $900,000 operating profit before tax, an assumed 25% tax rate, $5 million average invested capital, and 10% WACC.
CPAPass exam analysis using the stated assumptions
Show the work
NOPAT is $675,000. The capital charge is $5,000,000 x 10%, or $500,000. EVA is therefore $675,000 - $500,000.
Rule source: ICMA CSCA Formula Definitions: EVA, NOPAT, and WACCAnswer
EVA is positive $175,000, meaning the division earned more than its stated capital charge for the period.

The trap and the repair
Common trap
Subtracting interest before computing NOPAT and then charging for debt again through WACC double-counts financing cost. Using ending capital when the problem requires average capital also changes the answer.
Repair
Label operating profit, tax, compatible invested capital, and WACC on separate lines before calculating the capital charge.
Authority and scope boundary
The Blueprint explicitly includes economic value added in BAR. IMA materials support management-performance analysis, while the example uses a simplified CPAPass formula with stated inputs. Project-level NPV remains with capital budgeting.
2026 Uniform CPA Examination Blueprints and ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC were reviewed on 2026-08-14. Check a newer authority when the effective date or facts change.
EVA bridge
Separate operating return from the price of capital
EVA is only interpretable when NOPAT, invested capital, and WACC use compatible definitions and periods.
| Component | Calculation | Diagnostic question | Authority |
|---|---|---|---|
| NOPAT | Operating profit x (1 - stated tax rate), subject to supplied adjustments | Did financing cost enter the operating numerator? | ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC |
| Invested capital | Operating funding base specified by the problem | Are average and ending balances being mixed? | ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC |
| Capital charge | Invested capital x WACC | Do the rate and capital base use compatible assumptions? | ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC |
| EVA | NOPAT - capital charge | Did value rise from better operations or merely less capital? | ICMA CSCA Formula Definitions: EVA, NOPAT, and WACC |
After a miss
Review EVA through a four-line bridge
- 1
Recreate NOPAT, invested capital, WACC, and capital charge on four labeled lines.
- 2
Change one input at a time and explain the direction of the EVA effect.
- 3
Answer a new BAR calculation and compare the EVA conclusion with the limitation of a single-period measure.

Quick questions
What is the key rule?
Economic value added measures operating profit after charging the business for the capital it uses. In its common exam form, EVA equals net operating profit after tax minus invested capital multiplied by the weighted average cost of capital. Positive EVA means the period's NOPAT exceeded the required capital charge under the stated measurements and adjustments.
How can this topic be tested on the CPA Exam?
BAR can ask candidates to calculate NOPAT, invested capital, the capital charge, and EVA or interpret why EVA changes when profit, capital intensity, or WACC changes.
What mistake most often changes the result?
Subtracting interest before computing NOPAT and then charging for debt again through WACC double-counts financing cost. Using ending capital when the problem requires average capital also changes the answer. Label operating profit, tax, compatible invested capital, and WACC on separate lines before calculating the capital charge.
Where should I practice the decision?
After the worked example, open the BAR free-practice link and work a fresh question that tests the same decision. If the miss depends on Balanced scorecard, review that handoff before trying another set.
