Economic profit

Profit remaining after charging for the opportunity cost of the capital invested

Profit after the capital charge.

Economic profit asks whether operating earnings compensate providers of capital for both the amount invested and the risk of the investment. A common form is Economic Profit = NOPAT − (WACC × Invested Capital), where NOPAT is net operating profit after tax and WACC is the weighted average cost of capital. Equivalently, when definitions align, it is (ROIC − WACC) × Invested Capital.

In one sentence

Economic profit is after-tax operating profit minus the cost of capital applied to the capital invested in the business.

Let N denote defined after-tax operating earnings, K the aligned invested-capital base and w the required return for the earnings period. Economic profit is N − wK. If N is below wK, economic profit is negative even when N is positive. The equivalent excess-return expression requires ROIC = N/K using the same K; mixing an average-capital ROIC with a closing-capital charge breaks that equivalence.

The measure helps compare projects or units that use different amounts of capital and discourages growth that increases accounting earnings while earning below the cost of capital. It is an estimate, not a directly reported universal accounting line. WACC, invested capital, and operating adjustments require judgment, so show sensitivity rather than implying false precision.

Ways to express economic profit

Use consistent capital and earnings definitions and make adjustments visible.

NOPAT less capital charge

After-tax operating profit minus weighted cost of capital multiplied by invested capital.

Excess return times capital

Return on invested capital less cost of capital, multiplied by invested capital.

Incremental project profit

Expected incremental operating return less the opportunity cost of the additional capital required.

A continuum, not a switch

Economic profit adds a capital charge to operating performance so teams can distinguish profitable growth from growth that earns below the required return.

“Accounting profit can be positive while a business earns less than its capital requires.”

Why it matters

Revenue growth and reported earnings can hide capital intensity. A new business may require warehouses, equipment, receivables, or technology investment before it generates returns. Economic profit makes the capital charge visible and helps compare expanding an existing operation with investing in another opportunity.

Damodaran’s framework makes the earnings, capital and required-return choices explicit. An analyst should document adjustments under the accounting regime actually used, rather than mechanically add lease liabilities or capitalize research on top of figures that already incorporate those treatments. The capital charge is an analytical opportunity cost; it is not another invoice paid by the operating business.

Real-world examples

The same concept shows up in different ways across industries.

MicrosoftOperating income and net income are not an economic-profit estimate

→

Microsoft’s fiscal 2024 consolidated income statement reports operating income of $109,433 million and net income of $88,136 million. Operating income is before the chosen operating-tax adjustment; net income includes non-operating effects. Selecting either row without reconciling it to an operating earnings definition would hide an assumption. The filing’s balance sheet supplies accounting balances, but the analyst still has to choose an invested-capital policy and required return.

When it breaks

Economic profit is sensitive to accounting and finance choices. Expensing rather than capitalizing investment, goodwill treatment, operating leases, cash holdings, and tax normalization can change the result. A low estimate may reflect a high capital charge chosen by the analyst rather than an observed decline in cash profit.

Use the metric for a defined decision, not as a standalone ranking. A temporary negative result may be rational during a credible investment phase; a positive result does not prove customer value, resilience, or future returns. Compare multi-year outcomes and reinvestment needs, and test the cost of capital over a reasonable range.

A team can increase the current measure by cutting investment whose benefits arrive later. That makes a short reporting horizon a weak substitute for project valuation. Separate performance of existing assets from the value of future investment, and assess the cash consequences of a proposed decision over its actual horizon.

Key takeaways

01
Economic profit = NOPAT − WACC × invested capital.
02
Use aligned periods and state capital, tax, and adjustment assumptions.
03
Compare growth by incremental returns, not accounting profit alone.
