How this instrument works
Economic Value Added is a residual-income measure: it takes net operating profit after tax and subtracts a charge for every dollar sitting inside the business, whether that dollar came from a bank or from shareholders. Ordinary accounting profit stops at interest — it treats debt as a cost but equity as free, even though equity holders expect a return too. EVA closes that gap by pricing the whole funding base at its weighted average cost.
The charge is invested capital multiplied by WACC because the entire stock of financing is at risk for the whole period, not just the slice that shows up as an interest line. A division can report a healthy operating profit and still fail this test if the money tied up in its plant, inventory and receivables would have earned more sitting somewhere else at the same risk. A positive result means the business cleared that bar; a reading of zero means it earned exactly its cost of financing and created nothing extra.
The figure is only as honest as its two inputs. Stern Stewart's original EVA framework made dozens of adjustments to NOPAT and invested capital — capitalizing R&D, treating operating leases as debt, and more — so managers could not flatter the number with accounting choices alone. This instrument uses NOPAT and invested capital exactly as you supply them, and WACC is itself an estimate built from a company's borrowing rate and cost of equity, not a quoted market figure — so a small revision to the assumed WACC can flip the answer from positive to negative on numbers that have not otherwise moved.
- Enter NOPAT (net operating profit after tax), $ — operating income after tax, before any financing costs.
- Enter Invested capital, $ — the total debt and equity funding tied up in the business or unit.
- Set WACC, % — the blended rate that financing needs to clear before it creates value.
- Read Economic value added — the dollar amount left over once the charge is subtracted from NOPAT.
Worked example — $5,000,000 in capital at a 9% WACC
Take a division with NOPAT of $600,000, invested capital of $5,000,000, and a WACC of 9%. The charge against that capital is $5,000,000 × 9% = $450,000 — what the money would need to earn just to cover its own cost. Subtracting the charge from NOPAT leaves EVA = $600,000 − $450,000 = $150,000: real value created above and beyond the cost of the funding employed.
Drop NOPAT to $450,000 on the same $5,000,000 base and EVA falls to exactly zero — the business earns precisely its cost of financing and creates nothing extra despite reporting a substantial accounting profit. Drop it further, to $300,000, and EVA turns negative $150,000: the income statement still shows a profit, but the unit destroyed $150,000 of value once the true cost of the capital behind it is counted.
Questions
What's the difference between EVA and net income?
Net income only subtracts interest paid to lenders, treating equity as if it were free. EVA subtracts a charge on all invested capital — debt and equity together — at the company's WACC, so a business can post solid net income and still register a negative EVA once the true cost of the money tied up in it is counted.
Why charge WACC against invested capital instead of just against debt?
Because equity has a cost too, even though it never appears as an expense on an income statement. Shareholders expect a return for the risk they carry, and WACC blends that expected return with the interest rate on debt, so charging it against all invested capital treats both sources of financing on equal footing.
What counts as invested capital?
In its simplest form, invested capital is the debt and equity funding a business or unit — roughly total assets minus non-interest-bearing liabilities such as trade payables. Full EVA frameworks adjust this figure for items like capitalized leases and R&D; this instrument takes the number you enter as given.
Can EVA be negative even when the business is profitable on paper?
Yes, and it happens often. A unit can post a positive NOPAT and still show negative EVA if that profit does not clear the cost of the money it uses — see the worked example, where a NOPAT of $300,000 against the same $5,000,000 base produces an EVA of −$150,000 despite a real accounting profit.
Who actually uses EVA?
Corporate finance teams and boards use it to judge whether a division, plant, or acquisition creates value once the full cost of the money tied up in it is accounted for, and some companies tie manager bonuses to it directly so a unit cannot grow profit by simply consuming more financing at the same or lower return.
How is EVA different from ROI or ROIC?
ROI and ROIC are ratios — return divided by capital — so they say nothing about scale: a small, highly efficient unit can post a dazzling ROIC while adding almost no dollars of value. EVA is a dollar figure, so a large division earning a modest spread over its cost of financing can generate far more EVA than a small one earning a spectacular ratio.
