What it means
Economic spread compares two percentages: return on invested capital, which is operating profit after tax divided by the capital tied up in the business, and the weighted average cost of capital, which is the blended rate lenders and shareholders expect. Subtract the second from the first and you have the spread.
The measure matters because accounting profit alone can be misleading. A division can report a healthy profit and still be a poor investment if it consumes an enormous amount of capital to produce that profit, and the spread is the number that exposes this.
In practice, boards use economic spread to decide where growth money goes. A business unit with a positive spread should usually be given more capital, while a unit with a negative spread should be shrunk, repriced or sold, because growing it simply enlarges the shortfall.
Multiplying the spread by invested capital converts a percentage into a dollar figure, commonly called economic profit or residual income. That translation matters in practice, because a small spread on a very large capital base can be worth more than a wide spread on a tiny one.
The main nuance is that the cost of capital is an estimate rather than a fact, and small changes to it flip the answer. Sensible finance teams test the spread against a range of capital costs instead of defending a single figure to two decimal places.
Timing is the other thing to watch, because new investments often show a negative spread for their first two or three years. Judging a freshly built factory or a recent acquisition on this year's spread alone will condemn projects that were always expected to earn their return later, so the honest comparison is against the returns promised in the original business case.
In practice
Real-world examples.
Example
A grocery chain earns a 10% return on invested capital against a 7.5% cost of capital, giving a 2.5% spread. On $600,000,000 of invested capital, that is $15,000,000 of value created a year, which the board uses to justify further store openings.
Example
A heavy equipment rental firm reports rising profit but a falling spread, because each new depot needs $4,000,000 of machinery. Management responds by shifting towards longer rental contracts that raise utilisation instead of buying more fleet.
Example
A private equity owner reviews four portfolio companies and finds one with a negative spread of -1.8%. Rather than funding its expansion plan, the owner freezes capital spending and prepares the business for sale.
Formula
Calculation
Economic spread = Return on invested capital (ROIC) - Weighted average cost of capital (WACC)
Economic profit = Economic spread x Invested capital
Consider a distribution business with net operating profit after tax of $5,600,000 and invested capital of $40,000,000. Its ROIC is $5,600,000 / $40,000,000 = 14%.
The company's weighted average cost of capital is 9%. The economic spread is therefore 14% - 9% = 5%.
Converting that into money, economic profit is 5% x $40,000,000 = $2,000,000. The business is creating $2,000,000 of value a year above what its investors and lenders require, even though its accounting profit line shows a larger number that ignores the cost of equity entirely.Case study
Seen in the real world.
The following is an illustrative, fictional scenario. Meridian Print Group, an invented commercial printing company, ran two divisions that both reported profit. Packaging produced $3,200,000 of after-tax operating profit on $16,000,000 of invested capital, a 20% return, while Wide Format produced $1,200,000 on $20,000,000, a 6% return.
Against a cost of capital of 9%, Packaging had a spread of 20% - 9% = 11%, worth $1,760,000 of economic profit, while Wide Format had a spread of 6% - 9% = -3%, destroying $600,000 a year. The group's combined accounting profit had disguised this completely.
In this fictional case the board redirected the next three years of capital spending into Packaging and put Wide Format on a strict no-new-capital footing until its return improved. Group profit initially grew more slowly, but economic profit rose because capital stopped flowing to the weaker return.
Watch out
Common mistakes.
- Comparing ROIC to the interest rate on bank debt only. The cost of capital must blend debt and equity, and equity is always the more expensive of the two.
- Judging a business on spread alone. A narrow spread on a very large capital base can create far more value than a wide spread on a small one.
- Leaving leases and goodwill out of invested capital. Understating the capital base inflates ROIC and produces a spread that flatters the business.
Questions
People also ask.
Is economic spread the same as economic value added?
They are closely linked; the spread is the percentage gap, while economic value added is that gap multiplied by invested capital.
Can a fast-growing company have a negative spread?
Yes, and many do early on, which is acceptable only if the spread is credibly expected to turn positive as scale improves.
How often should the spread be recalculated?
Annually for planning, with a fresh look whenever the capital structure, interest rates or the asset base change materially.
