The Three Approaches to Business Valuation — And Why You Need More Than One

Ask a small-business owner what their company is worth and you will get a single number. Ask a professional valuator the same question and you will get three numbers, a reconciliation paragraph, and usually a range. The difference is not cautiousness. It is discipline — and it maps directly to how every serious valuation standard in the world is built.

There are three approaches to business valuation: income, market, and asset. A credible report uses at least two of them, runs each to an independent conclusion, and then reconciles the results with explicit weighting. The reconciliation is where judgment lives. Everything upstream is math.

Income approach: what the business is worth based on what it produces

The income approach values a business on the future cash it will generate, discounted back to today. It answers a simple question: if this business were a bond, what would you pay for the coupon stream?

There are two main methods inside the income approach.

Capitalization of earnings uses a single year of normalized earnings — typically a trailing twelve months or a weighted average of the last three to five years — and divides by a capitalization rate. The cap rate is the required return minus the expected long-term growth rate. A 24% required return with 4% growth yields a 20% cap rate, which is a 5.0x multiple. Capitalization of earnings is fast, transparent, and appropriate for stable businesses with predictable cash flow.

Discounted cash flow (DCF) projects earnings year by year, usually for five to ten years, then calculates a terminal value at the end of the projection period. Each year's projected cash flow gets discounted back at the weighted average cost of capital. DCF is the right tool when the business has a clear growth trajectory, known inflection points, or material capital needs — a SaaS company scaling through a user base, a manufacturer mid-expansion, a services firm with a large contract pipeline.

Income approaches are only as good as the inputs. The discount rate carries enormous weight — a 300 basis point change in the rate can swing the conclusion by 25%. That is why professional valuators build the discount rate from published components (risk-free rate, equity risk premium, size premium, company-specific risk) rather than picking a number. Kroll's size premium data and Damodaran's industry beta tables are the reference points for that build.

Market approach: what the business is worth based on what similar ones sold for

The market approach values a business by reference to actual transactions in comparable businesses. If businesses like yours trade at 4.2x EBITDA, your business is probably worth something close to 4.2x your EBITDA, adjusted for the differences.

There are two methods here.

Guideline comparable transactions uses closed private-company transactions — the same industry, similar size, similar geography where possible. The data sources are DealStats (formerly Pratt's Stats), BizBuySell, and a handful of industry-specific databases. You pull maybe twenty to forty comparable deals, throw out the outliers, and look at the median and interquartile range of multiples. Then you position your subject company inside that range based on its growth, margins, concentration, and recurring revenue profile.

Guideline public companies uses publicly traded companies as the reference. This method is more common at the upper end of the middle market where public comparables actually exist. Size and liquidity adjustments are required — a public company is worth more than a private company of identical earnings because the public company has marketability and institutional ownership. That gap is the private-company discount, which runs 20% to 35% depending on the study.

The market approach is the most intuitive of the three because it relies on revealed preferences — what real buyers paid for real businesses. Its weakness is that comparables are never perfect. The valuator's judgment on which deals to include and how to position the subject drives the answer more than most people realize.

Asset approach: what the business is worth based on what it owns

The asset approach values the business as the sum of its adjusted net assets — tangible and intangible — minus its liabilities. For operating businesses this is usually the floor, not the answer. But in three situations the asset approach leads:

Asset-heavy businesses with modest earnings. A small manufacturer with $4M in equipment and $200K in SDE may be worth more broken up than as a going concern. The asset value sets a floor below which no rational seller would transact.

Holding companies and investment entities. A real-estate LLC is worth its adjusted NAV. There is no operating goodwill to value.

Distressed or unprofitable businesses. If the income approach produces negative value and the market approach has no comparable sales, the asset approach is often the only defensible answer.

The mechanics are conceptually simple and practically messy. Every balance sheet item gets revalued to fair market value. Equipment and inventory may need independent appraisal. Customer lists, trade names, and proprietary software must be valued as identifiable intangibles — usually through a relief-from-royalty or cost-to-recreate method. The resulting adjusted book value is what the business would fetch if its components were sold.

Why you need more than one

A single approach is a single point of view. Three approaches triangulate. When they agree, you have a defensible conclusion. When they disagree, the disagreement tells you something important about the business.

Imagine a landscaping company with:

• Income approach: $1.85M (based on $400K of capitalized earnings at a 21.6% cap rate)
• Market approach: $1.42M (based on 3.55x SDE multiple from 22 comparable deals)
• Asset approach: $820K (equipment, trucks, inventory, minimal intangibles)

The gap between income and market is 30%. That gap is telling you something: either the capitalization rate is too low (understating risk), the comparables reflect a different tier of business, or the company has genuine income-producing characteristics that the market has not priced in. The valuator's job is to explain the gap and then weight the conclusions.

Typical weighting in this case might be 50% market / 40% income / 10% asset, producing a concluded value near $1.55M. The weights are judgment calls, but they have to be defended in writing. A credible report shows the reader exactly why the weights were chosen, not just what they are.

Why online calculators get this wrong

Almost every free online "business valuation calculator" uses a single approach — usually a crude revenue multiple dressed up as the market approach. No income analysis. No asset reconciliation. No discount-rate build. No comparable selection. Just revenue times a number.

The result is predictable: the calculators produce wildly different numbers for the same business because the "industry multiple" they use is a single national median applied without adjustment for size, concentration, growth, or risk. Run the same business through five of them and you will get a range of 2x. That is not a valuation. That is a guess with a header.

Professional valuators run all three approaches because the reconciliation is the valuation. A number without a reconciliation is not a valuation opinion — it is an opinion about a number.

How VEMLogic does this

VEMLogic runs all three approaches on every Professional report and reconciles them with explicit weights. The income approach uses both capitalization of earnings and DCF where DCF is appropriate. The market approach pulls comparable transactions from published databases and applies size-tier adjustments from Kroll. The asset approach runs in the background on every engagement and leads when the earnings case is weak. The final conclusion is a single number backed by three independent lines of reasoning, not a single multiple backed by an industry average.
