Economic Profit: NOPAT Minus Capital Charge

GAAP accounting profit charges the income statement for interest on debt but charges nothing for the cost of equity capital. That asymmetry means a company can grow reported earnings every year while bleeding economic value to shareholders -- because half of the cost of capital is invisible on the income statement. Economic profit fixes the gap: it subtracts a full capital charge (WACC times invested capital) from after-tax operating profit, so the residual is the true dollar value the business created (or destroyed) above its capital cost. For a lifelong investor, the economic-profit lens turns the noisy GAAP series into the clean answer to the question that actually matters: did this company create wealth above what its capital required to be raised?

Economic Profit = NOPAT - (WACC x Invested Capital)

What the Metric ShowsGAAP Net IncomeEconomic Profit
Cost of debtCharged (interest expense)Charged (in WACC)
Cost of equityNOT charged -- invisible to the income statementCharged (in WACC)
Capital intensity penaltyNone -- a high-capital business and a low-capital business with the same earnings look identicalCaptured -- the capital charge scales with invested capital
Reinvestment qualityImplicit and hard to readExplicit -- growth at sub-WACC ROIC drives economic profit down even as earnings rise
§ 03

The cost of equity is the silent line missing from every GAAP income statement. Equity capital is not free; shareholders demand a return that compensates them for the risk of holding the stock. Economic profit makes that demand visible by deducting it directly. The lifelong investor's reflex: never let an earnings headline travel without the economic-profit check.

§ 04
Pull NOPAT, invested capital, and an estimated WACC for a mature company in your portfolio. Compute the capital charge (WACC times invested capital) and subtract it from NOPAT. Run the same calculation for the prior year. Is economic profit rising or falling? If it is rising while GAAP earnings are flat, the business is becoming more capital-efficient. If it is falling while GAAP earnings are rising, the company is growing the wrong way -- earnings are coming from capital deployment that does not clear the hurdle.
§ 05
A regional bank reports five consecutive years of growing GAAP earnings per share. Invested capital has more than doubled over the same period, mostly through retained earnings and a secondary equity issuance. Economic profit has been flat to slightly negative each year. What is the most disciplined interpretation?
§ 06

GAAP earnings can grow every year while shareholder value shrinks. The cost of equity is the silent line missing from the income statement; economic profit puts it back in. The investor who tracks economic profit alongside GAAP earnings sees true value creation before the multiple confirms it.

Sit with the ideas.

A mature industrial company reports record GAAP net income of $400M, up 8% year-over-year. Invested capital is $5,000M and WACC is 9%. NOPAT (after-tax operating profit before financing effects) is $420M. What does the economic profit calculation tell a lifelong investor that the GAAP headline does not?
