Economic Value Added (EVA): Formula, Adjustments and Numericals

Updated 11 October 2026 · Fact-checked

Economic Value Added is the profit left after charging for all capital, debt and equity. EVA = NOPAT − (WACC × Invested Capital). Compute NOPAT after tax, find WACC, apply it to capital employed at the start of the year, then subtract. A positive EVA means value was created.

Understand Economic Value Added (EVA)

Accounting profit ignores one cost: the cost of equity. A company can show a profit and still destroy value if that profit is lower than what investors expect for the risk they bear. EVA fixes this by charging for all capital used.

EVA is the operating profit after tax minus a charge for the capital employed in the business. If the result is positive, the firm earned more than investors require. If it is negative, it earned less, even if the profit and loss account shows a profit.

NOPAT (Net Operating Profit After Tax) is the profit from operations after tax, before interest. Interest is left out because the capital charge already covers the cost of debt. The capital charge is WACC multiplied by invested capital.

WACC is the weighted average of the after-tax cost of debt and the cost of equity, using the capital structure weights (usually market or target values, as the question states). Cost of equity is often found by CAPM: Rf + β × (Rm − Rf).

EVA is also used with adjustments. Accounting treats some spending, such as R&D, as an expense, though it builds future value. The adjusted EVA capitalises such items, which raises both NOPAT and capital. Questions usually state which adjustments to make.

Key rules to remember

EVA
EVA = NOPAT − Capital charge
Positive EVA means value created; negative means value destroyed.
Capital charge
Capital charge = WACC × Invested capital
Use the capital figure the question specifies, usually opening capital employed.
NOPAT
NOPAT = EBIT × (1 − tax rate)
EBIT is operating profit before interest and tax. Do not deduct interest.
EVA by spread
EVA = (ROIC − WACC) × Invested capital
ROIC = NOPAT ÷ Invested capital. Useful as a cross-check.
WACC
WACC = Ke × We + Kd × (1 − t) × Wd
Weights are of equity and debt in total capital.
Cost of equity (CAPM)
Ke = Rf + β × (Rm − Rf)
Use when the question gives beta and market data.
Invested capital
Invested capital = Equity + Debt (or Net fixed assets + Net working capital)
Both routes should agree. Adjust for items such as capitalised R&D if told.

How to solve Economic Value Added (EVA) questions

Use this order for any EVA question. It keeps the working clean and earns step marks.

  1. 1Read which capital figure is to be used: opening, closing, average, or book versus market value.
  2. 2Find EBIT. If given profit after interest, add back interest to get operating profit, and remove non-operating income if told.
  3. 3Make the stated adjustments to EBIT, such as adding back R&D expense or provisions treated as capital.
  4. 4Compute NOPAT = adjusted EBIT × (1 − t).
  5. 5Compute the cost of equity, then the after-tax cost of debt, then WACC using the given weights.
  6. 6Adjust invested capital for the same items (for example, add capitalised R&D) and find the capital charge.
  7. 7Compute EVA = NOPAT − capital charge. Cross-check with (ROIC − WACC) × capital.
  8. 8State the conclusion in one line: value created or destroyed, and what management should do.

Quickest way: Spread shortcut

When to use it: Use when the question gives ROIC or NOPAT and capital directly, and asks only for EVA or a comparison between divisions.

  1. Find ROIC = NOPAT ÷ Invested capital.
  2. Subtract WACC to get the spread.
  3. Multiply the spread by invested capital.
  4. Check the sign, then write the recommendation.

Common mistakes in Economic Value Added (EVA)

  • Deducting interest while computing NOPAT.

    Students start from profit after interest and forget that the capital charge already covers debt cost.

    Fix: Start from EBIT, or add back interest to profit before tax, then apply the tax rate.

  • Using the pre-tax cost of debt in WACC.

    The interest rate is given and used directly.

    Fix: Always multiply the cost of debt by (1 − t) before weighting.

  • Charging only for debt or ignoring the cost of equity.

    Students are used to interest being the only visible financing cost.

    Fix: The capital charge uses WACC on total capital, so equity is always charged.

  • Adjusting profit for R&D or similar items but not capital.

    Students treat the adjustment as a profit change only.

    Fix: When you add back an expense to NOPAT, add the capitalised amount to invested capital too.

  • Using the wrong capital base, such as closing instead of opening.

    The question wording is skimmed.

    Fix: Underline the capital basis in the question before starting.

  • Giving a number with no conclusion.

    Students treat EVA as pure arithmetic.

    Fix: End with a sentence on value created or destroyed and the decision that follows.

Worked examples

Example 1

A company has EBIT of ₹60 lakh, tax rate 25%, equity ₹200 lakh and 10% debt ₹100 lakh. Cost of equity is 16%. Invested capital equals equity plus debt. Compute EVA and comment.

Show the solution
  1. NOPAT = 60 × (1 − 0.25) = ₹45 lakh.
  2. After-tax cost of debt = 10% × (1 − 0.25) = 7.5%.
  3. Weights: equity 200 ÷ 300 = 2/3; debt 100 ÷ 300 = 1/3.
  4. WACC = (16% × 2/3) + (7.5% × 1/3) = 10.667% + 2.5% = 13.167%.
  5. Capital charge = 13.167% × 300 = ₹39.5 lakh.
  6. EVA = 45 − 39.5 = ₹5.5 lakh.
  7. Cross-check: ROIC = 45 ÷ 300 = 15%; spread = 15% − 13.167% = 1.833%; × 300 = ₹5.5 lakh.

Answer: EVA is ₹5.5 lakh. It is positive, so the company earned more than its investors require and created value.

Example 2

A firm reports EBIT of ₹90 lakh after charging R&D of ₹10 lakh. Management wants R&D treated as capital: assume ₹30 lakh of past and current R&D is to be added to capital. Book invested capital is ₹400 lakh, tax rate is 30%, and WACC is 12%. Compute the adjusted EVA.

Show the solution
  1. Adjusted EBIT = 90 + 10 = ₹100 lakh (R&D expense added back).
  2. Adjusted NOPAT = 100 × (1 − 0.30) = ₹70 lakh.
  3. Adjusted invested capital = 400 + 30 = ₹430 lakh.
  4. Capital charge = 12% × 430 = ₹51.6 lakh.
  5. Adjusted EVA = 70 − 51.6 = ₹18.4 lakh.
  6. Unadjusted check: NOPAT = 90 × 0.7 = 63; charge = 12% × 400 = 48; EVA = ₹15 lakh.

Answer: Adjusted EVA is ₹18.4 lakh against ₹15 lakh unadjusted. Capitalising R&D raises NOPAT and capital, and here the net effect increases EVA. It is positive either way.

Exam tips

  • Write the formula line first. Step marks are given even if a later figure is wrong.
  • Show WACC working separately, with the after-tax cost of debt visible.
  • In MCQs, check whether the question gives profit after interest or EBIT before you pick NOPAT.
  • In descriptive answers, give at least two advantages and two limitations, each in a short line with a reason.
  • Limitations to remember: depends on accounting data and adjustments, uses book capital, is an absolute figure that favours large units, and may encourage short-term focus.

Economic Value Added (EVA): frequently asked questions

What is the EVA formula for CMA Final?

EVA = NOPAT − (WACC × Invested capital). NOPAT is EBIT × (1 − tax rate). You can also write it as (ROIC − WACC) × Invested capital.

Why is interest not deducted in NOPAT?

The capital charge already charges for debt at its cost within WACC. Deducting interest in NOPAT would charge debt twice.

What are the advantages and limitations of EVA?

EVA links performance to shareholder wealth, charges for equity, and encourages efficient use of capital. It relies on accounting data and adjustments, depends on the WACC estimate, and as an absolute number it is hard to compare across units of different size.

Which adjustments are made to EVA?

Common ones are capitalising R&D, advertising or training spend, and adding back provisions treated as reserves. Whenever you change NOPAT, make the matching change to invested capital, unless the question says otherwise.
