Capitalization Rate vs Discount Rate in Business Valuation

A discount rate is applied to a forecast of future cash flows. A capitalization rate is applied to a single normalized year. They differ by exactly one thing: the long term growth rate. Capitalization rate equals discount rate minus growth. A business discounted at 22% with 3% sustainable growth carries a 19% capitalization rate, which is the same as a 5.26x multiple of that cash flow.

Appraisers use both, often in the same report, and the words get swapped so casually that owners reading a valuation come away thinking the analyst used two different opinions about risk. They did not. The two rates encode identical assumptions and are converted into one another with a subtraction. What actually differs is the shape of the cash flow you are pricing.

Is cap rate and discount rate the same?

No, but they are built from the same components. The discount rate is your required return, full stop. The capitalization rate is that same required return with expected long term growth taken out, because when you apply a single rate to one year of earnings you have to embed the growth of every future year somewhere. Subtracting it from the rate is where it goes.

The two methods give the same answer, and here is the proof

Take a service business with $400,000 of seller discretionary earnings. A competent manager to replace the owner would cost $110,000, maintenance capital spending runs $20,000 a year, and tax takes 25%. Net cash flow to a buyer is therefore ($400,000 less $110,000 less $20,000) taxed at 25%, which is $202,500. Assume a 21.8% discount rate and 3% sustainable long term growth.

Capitalize it. The capitalization rate is 21.8% less 3%, which is 18.8%. Applied to next year's cash flow of $208,575, that gives a value of $1,109,441.

Now build a five-year discounted cash flow instead. Grow the $202,500 at 3% a year, discount each year at 21.8%, then add a terminal value calculated by capitalizing year six at the same 18.8%. The five explicit years are worth $629,648 in present value terms. The terminal value is $1,286,147, worth $479,793 discounted back. Total: $1,109,441.

Identical, to the dollar. That is not a coincidence or a rounding accident. A discounted cash flow with a constant growth rate and a perpetuity terminal value is algebraically the same expression as a capitalization. All the extra work bought you nothing, because the forecast contained no information the single-year capitalization did not already have.

For reference, that business would sell for roughly $1,080,000 at the median 2.7x SDE multiple US small businesses actually closed at in 2026. The rate-based answer and the market-multiple answer land within 3% of each other, which is the useful part.

So when should you use each one?

The choice is about the shape of the earnings, not about how sophisticated you want to look.

Capitalize a single year when the business is mature and earnings are genuinely repeatable. A dental practice, an insurance book, a route business, a laundromat, an established HVAC contractor with steady service revenue. If next year looks like this year plus inflation, a five-year forecast is three extra assumptions and zero extra information.

Discount a forecast when the earnings path is genuinely different from the current year. A contract that starts in month eight, a second location opening, a rent step-up, a customer you know is leaving, a capital program that suppresses cash flow for two years and then stops. Those facts cannot be expressed in a single year, so they have to go in a forecast.

The honest test is whether you can defend the forecast. If your five-year plan is this year multiplied by 1.05 four times, you have built a capitalization with extra steps and given yourself two more numbers to argue about. That is worse, not better.

How to build the discount rate before you subtract anything

Neither rate means anything until the discount rate is right, and for a private company you cannot look it up. Public sector rates do not apply: US listed companies carried a weighted average cost of capital of 6.96% in January 2026, with a median sector at 7.08%. No buyer prices an owner-operated business at 7%.

Appraisers use a build-up instead, adding one component at a time:

The first two lines are lookups. The last three are judgment, and the company specific premium is where two competent appraisers most often part company by three or four points on the same set of books. Three points on a business earning $400,000 is worth about $150,000 of value, so the paragraph explaining that number matters more than the number does. Our cost of capital by industry reference carries the full sector table and the ranges each component is defended in.

Diligence findings land here rather than in the earnings. A contractor whose books tie cleanly to the tax returns, whose customer base has no single name above 15%, and who can show that subcontractor insurance certificates are tracked and current, is not a lower-risk business by accident. Each of those is a specific reason a buyer takes a point off the rate, and each one is fixable in the year before a sale.

The growth rate you subtract is where most cap rates go wrong

The growth figure in the capitalization rate is not next year's growth. It is the rate the business can sustain forever, after the current owner and the current market conditions are gone. For most small businesses that is inflation, roughly 2% to 3%. It is almost never 8%.

The arithmetic punishes optimism brutally, because growth sits in the denominator. At a 22% discount rate, moving assumed growth from 3% to 8% cuts the capitalization rate from 19% to 14% and lifts the implied multiple from 5.26x to 7.14x. That is a 36% increase in value bought with an assumption nobody can prove. Buyers know this, which is why an aggressive long term growth rate in a seller's valuation is treated as a signal about the seller rather than about the business.

One more mismatch to avoid: the growth rate has to be consistent with the reinvestment in your cash flow. If you assume 6% perpetual growth while modeling capital spending equal to depreciation, you are assuming growth with nothing funding it.

What is a good capitalization rate for a business?

For a small owner-operated US business, 15% to 22% is the normal band, which corresponds to a 6.67x down to a 4.55x multiple of net cash flow. Lower than 12% implies either a large, professionally managed company or an assumption that the buyer will accept a public-market return for private-market risk. Above 25% usually means the analyst has priced in serious owner dependency or customer concentration, and is worth reading the narrative for.

Those multiples apply to net cash flow after a market rate owner salary, after tax and after maintenance capital spending. They are not SDE multiples and they are not EBITDA multiples. Apply a 5.88x to your SDE and you will be roughly double the market. For what buyers actually pay on the earnings measures they quote, use the SDE multiples by industry table for owner-operated businesses and the EBITDA multiples by industry table above roughly $1M of earnings.

Why the real estate version confuses everyone

In commercial real estate a cap rate is net operating income divided by price, quoted straight off closed sales. A 7% cap rate on an apartment building is an observed market fact, not a built-up opinion, and it already embeds growth expectations without anyone stating them.

In business valuation the capitalization rate is derived, not observed. You build the discount rate and subtract growth. The two concepts share the same arithmetic relationship to value, one divided by the rate, but they are sourced completely differently, and the numbers are not interchangeable. A property cap rate of 6% to 8% and a business capitalization rate of 15% to 22% describe genuinely different risks: real estate has collateral, a long asset life and a deep financing market. A service business has a customer list and a truck.

Four mistakes that show up in real valuations

Capitalizing a peak year. The single year you capitalize has to be normalized, meaning it represents sustainable performance. Capitalizing the one year revenue spiked 40% builds that spike into every future year at once.

Mixing the cash flow with the rate. Discount cash flow to the firm, measured before interest, at a weighted average cost of capital. Discount cash flow to equity, measured after debt service, at a cost of equity. Applying the lower blended rate to an equity cash flow counts the benefit of debt twice.

Capitalizing SDE. SDE includes the owner's salary. A capitalization rate is built for cash flow a passive investor would receive. Capitalize SDE at 19% and you value the owner's job as if it were profit.

Precision that is not there. A discount rate carrying a five-point judgment component does not support an answer quoted to the dollar. Report a range. At a 20% rate, one point of error moves value 5.6%, and the company specific premium is comfortably worth more than one point of disagreement.

The practical version

Build your discount rate honestly from the risk-free rate up, subtract only the growth you could defend under cross-examination, and use the resulting capitalization rate on one normalized year. Then check the answer against what businesses like yours actually sold for. If the two are within 10% of each other, you have a defensible number. If they are not, one of your judgment calls is doing more work than it should, and finding out which one is the entire value of the exercise.
