Economic value added asks a question accounting profit never does: after paying for every unit of capital tied up in the business, is anything left? Reported profit already deducts the cost of debt through interest, but it charges nothing at all for equity, which is why a company can post a healthy profit while destroying value for the people who funded it. EVA closes that gap by subtracting a charge for the whole capital base.
Arb Digital built this page around the two things that actually determine an EVA figure: the cost of capital you assume, and the accounting adjustments you make. Both are choices, and this tool takes both as inputs and names them on the page. It publishes no cost of capital, no company data and no benchmark. Where our ROIC calculator reports the return as a percentage against a hurdle, this page reports the surplus in money; and where the economic profit calculator deducts an owner-operator's opportunity costs in a small business, this one applies the corporate-finance capital charge to a whole balance sheet.
What This EVA Calculator Does
It converts operating profit into net operating profit after tax, applies your chosen accounting adjustments, multiplies invested capital by your cost of capital to get the capital charge, and subtracts one from the other. It reports EVA in money, along with NOPAT, the capital charge, the return on invested capital and the spread between that return and your WACC.
The spread matters because it is the same result expressed as a rate, and the two views answer different questions. EVA in money tells you the size of the value created. The spread tells you the quality of it, independent of scale, and a small business with a wide spread is often more interesting than a large one with a thin positive EVA.
It also supports the two capital-charge conventions — opening capital or an average of opening and closing — because in any year the capital base moves, those give different answers and pages rarely say which they used.
How to Use It
- Enter operating profit and the tax rate you want applied. A cash tax rate derived from tax actually paid usually reflects reality better than the statutory rate.
- Enter invested capital on a stated basis: total debt plus equity, or net operating assets. Both are used; they should give similar answers, and if they do not, something is classified inconsistently.
- Enter your own WACC. This is the input that dominates the result, and reaching for a round number here undermines everything downstream.
- Decide on adjustments deliberately. They default to zero so that the base case is the unadjusted one, and any adjustment you make is visible.
- Read EVA and the spread together, and record the assumptions alongside the number. An EVA figure without its WACC and its adjustments cannot be compared with anything.
The Formula
Two lines:
NOPAT = EBIT × (1 − tax rate)
EVA = NOPAT − (Invested capital × WACC)
A worked example on the defaults. Operating profit of 5,000,000 at a 25 per cent tax rate gives NOPAT of 3,750,000. Invested capital of 30,000,000 at a 9 per cent cost of capital gives a capital charge of 2,700,000. EVA is 3,750,000 − 2,700,000 = 1,050,000.
The identical result comes from the spread form: return on invested capital is 3,750,000 ÷ 30,000,000 = 12.5 per cent, the spread over a 9 per cent WACC is 3.5 per cent, and 3.5 per cent of 30,000,000 is 1,050,000. That equivalence is worth knowing, because it shows EVA is only ever ROIC and WACC in disguise, scaled by size. Damodaran's teaching note on economic value added presents it in exactly that spread form.
Where adjustments are used, the arithmetic runs on adjusted figures: adjusted operating profit is EBIT plus capitalised R&D minus its amortisation, and adjusted capital is invested capital plus the additions you specify. The same two lines then apply unchanged.
The Cost of Capital Is the Whole Argument
EVA is exquisitely sensitive to WACC. On the default figures, moving the cost of capital from 9 to 10 per cent cuts EVA by 300,000, nearly a third. Move it to 12.5 per cent and EVA is exactly zero. The company has not changed at all; only the assumption has.
That sensitivity is not a flaw in the metric, it is the metric working correctly — the whole point is that capital has a price. But it does mean an EVA figure quoted without its WACC is not information. It also means the WACC has to be built rather than assumed: the capital structure, the cost of debt, an equity risk premium and a beta all feed into it, and every one is an estimate. Our WACC calculator makes those inputs explicit.
A practical discipline is to compute EVA across a range of costs of capital rather than at a point, and to find the rate at which it crosses zero. That break-even cost of capital is a more robust statement than a single EVA figure, because it tells the reader how much room the assumption has before the conclusion flips.
Which Adjustments This Page Makes, and Which It Does Not
The commercial versions of EVA apply a long list of accounting adjustments intended to convert reported figures into something closer to economic reality. This page is explicit about its own position.
It offers two adjustments, both off by default: capitalising research and development expensed in the period, with a matching amortisation charge, and adding a specified amount to invested capital, which is where you would bring in capitalised operating leases or the cumulative capitalised R&D balance.
It does not make any of these: restating inventory from LIFO to FIFO, adding back cumulative goodwill amortisation or writing goodwill back into capital, capitalising advertising or brand-building spend, adjusting for deferred tax, restating provisions and restructuring charges, adjusting for pension surpluses and deficits, marking assets to current cost, or removing non-recurring items. Each is defensible, each changes the answer, and a page that applied them silently would be producing a number nobody could reproduce.
The consequence follows directly: published EVA figures are not comparable between firms unless you know which adjustments each one used. Two analysts working from identical accounts can produce materially different EVA numbers, both correct on their own basis. Always record your adjustment set alongside the result.
Invested Capital Is Harder Than It Looks
The capital figure has to be consistent with NOPAT, and that consistency is where most errors live. NOPAT is a return to all providers of capital, before interest, so invested capital must be all capital: debt plus equity, or equivalently net operating assets. Mixing an all-capital return with an equity-only capital base overstates the return badly.
Excess cash is the recurring problem. Cash that is not needed to operate generates no operating profit, so leaving it in the capital base creates a charge with no matching return and understates EVA. Strip it out, and strip out the associated interest income from the profit figure too. Non-operating investments and assets held for sale get the same treatment.
The opening-versus-average choice matters more than it appears. Capital deployed on the last day of the year cannot have earned anything, so charging a full year's cost on a closing balance penalises investment. Opening capital is the more logical basis for a single year; averaging is common where capital moves steadily. This calculator supports both, and consistency across years matters more than which one you pick. The ROIC calculator and DuPont analysis calculator face the same choice.
What EVA Is Good At, and Where It Fails
Its genuine strength is behavioural. Managers judged on profit have an incentive to accumulate capital, because capital produces profit and costs them nothing in the metric. Managers judged on EVA have an incentive to release capital that is not earning its keep, and to reject projects that add profit but not value. That is a real and useful change in incentives, which is why it has been used in compensation design.
Its weakness is that it is a single-period measure applied to businesses whose investments span many periods. A company making a large, correct, long-horizon investment posts a negative EVA in the year it spends and for several years afterwards, because the capital charge starts immediately and the returns do not. Judged annually, EVA discourages exactly the investment it should encourage. That is the mirror image of the discounted cash flow view, and our NPV calculator is the right tool when the horizon is long.
It is also silent on the things that determine the future: competitive position, the durability of the spread, and whether the returns can be reinvested at the same rate. The CFA Institute's material on residual income valuation covers the wider framework EVA belongs to, including how a series of residual income figures relates to value.

- Quoting EVA without the WACC — on the default figures a one-point change moves the answer by nearly a third, so the number means nothing without the assumption attached.
- Mismatching return and capital — NOPAT is a return to all capital providers, so the capital base must include debt as well as equity.
- Leaving excess cash in invested capital — it attracts a capital charge while producing no operating profit, which understates EVA for no good reason.
- Applying adjustments silently — capitalising R&D or leases without saying so produces a number nobody else can reproduce, and comparisons with other companies become meaningless.
- Judging a long-horizon investment on one year — the capital charge starts immediately and the returns do not, so a correct investment looks value-destroying while it is being made.

Frequently Asked Questions
Economic value added equals net operating profit after tax minus a capital charge, where the capital charge is invested capital multiplied by the weighted average cost of capital. NOPAT is normally operating profit times one minus the tax rate, before any adjustments you choose to apply.
Because the capital charge is the cost of capital multiplied by the entire capital base, so a small change in the rate moves a large amount of money. On the default figures a single percentage point changes EVA by 300,000. That is why the assumption must always travel with the number.
Not without knowing the adjustments behind each one. Commercial EVA methodologies apply long lists of accounting adjustments, different practitioners apply different subsets, and each changes the result. Two correct calculations from identical accounts can differ materially.
Only the two you switch on: capitalising R&D with a matching amortisation charge, and adding a specified amount to invested capital for items such as capitalised leases. It does not restate inventory, goodwill, provisions, deferred tax, pensions or non-recurring items, and it says so rather than doing it quietly.
They are the same comparison expressed differently. ROIC minus WACC is the spread as a rate; multiplying that spread by invested capital gives EVA as an amount. The rate tells you the quality of the return, and the amount tells you how much value the scale of the business produced.
That the return on the capital employed fell short of what that capital costs in the period measured. It does not automatically mean the business is failing: a year of heavy investment produces a negative figure by construction, because the charge begins before the returns do.
Opening capital is the more logical basis for a single period, since capital deployed on the final day cannot have earned anything. Averaging is common where the base moves steadily through the year. Either is defensible; using the same one every year is what actually matters.
No. Cash beyond operating needs earns no operating profit, so charging capital against it depresses EVA without cause. Remove it from the capital base and remove the related interest income from profit, so that both sides of the calculation refer to the same operating business.
This tool is provided for informational and educational use only. It is not investment, accounting or financial advice, and it makes no assessment of any company. EVA depends entirely on the cost of capital assumed and the accounting adjustments chosen, both of which are yours rather than the tool's.
