Buyers value a small business for sale by taking its normalized earnings, usually seller discretionary earnings (SDE) for owner-run companies or adjusted EBITDA for larger ones, and multiplying them by a multiple that reflects risk and growth. They cross-check that answer against revenue multiples and comparable sales, and the result is a range, not a single number.

The rest of this guide walks through each method, what moves the multiple up or down, and how to get a range for your own business before a buyer sets the anchor for you.

The short version

  1. Normalize the earnings. Start from your profit and add back expenses a new owner would not carry, such as one-time costs or owner pay above market rate.
  2. Choose the earnings measure. SDE for a business where the owner works in it full time, adjusted EBITDA where a management team runs it.
  3. Apply a multiple. The multiple reflects how much risk a buyer sees and how much growth they expect.
  4. Cross-check. Compare the answer against revenue multiples and what similar businesses have sold for.
  5. Express it as a range. Different buyers will see different risks and opportunities, so the honest answer is a low, middle and high case.

The four ways buyers value a business

1. Earnings multiple

This is the method most buyers start with. The value is a multiple of normalized earnings:

Normalized earnings x multiple = enterprise value

Which earnings figure a buyer uses depends on how the business runs:

  • Seller discretionary earnings (SDE) is pre-tax profit plus one owner’s total compensation and benefits, plus add-backs such as interest, depreciation, amortization and one-time costs. It is used for owner-operated businesses, where the buyer will usually step into the owner’s role.
  • Adjusted EBITDA is earnings before interest, taxes, depreciation and amortization, plus add-backs, with a market-rate salary in place for every role, including the CEO. It is used once a business has a management team and a buyer expects to own it rather than run it day to day.

The multiple is where most of the negotiation happens. It is the buyer’s price for risk and growth: a higher multiple means they see durable, transferable earnings with room to grow, and a lower one means they see risk they will need to manage or price in.

2. Revenue multiple

Some businesses are valued on revenue instead of earnings, usually because their earnings do not yet show what the business can produce. A fast-growing software company that reinvests everything in growth may have little or no profit, so buyers price it on annual recurring revenue (ARR). For most profitable founder-owned businesses, a revenue multiple is a cross-check rather than the main method: if the earnings-based value implies a revenue multiple far out of line with similar businesses, something needs explaining.

3. Comparable transactions

Comparable sales ask what buyers have actually paid for similar businesses: same industry, similar size, growth and margin. This is the most persuasive evidence in a negotiation, and the hardest to get right. Most private company sale prices are never published, so comparable data comes from transaction databases, industry reports and the deal experience of the advisors and buyers involved. Treat any single comparable with caution: the terms behind a headline price, such as earnouts, seller financing and what was included, can make two similar-looking deals very different.

4. Discounted cash flow (DCF)

A discounted cash flow model projects the cash the business will produce over several years and discounts it back to today at a rate that reflects risk. It matters most for larger companies with predictable cash flows, and for buyers modeling a specific plan, such as a strategic buyer estimating what the business would earn inside their own company. For most smaller businesses, buyers lean on multiples because a long forecast for a founder-run company carries too much uncertainty to anchor a price on its own.

A worked example

The numbers below are round and for illustration only. They are not market rates.

A services business reports $3 million of EBITDA. The owner pays themself $400,000 a year in a role a market-rate CEO would fill for $250,000, and the year included a one-time $100,000 legal bill. Adjusted EBITDA is $3 million plus $150,000 plus $100,000, or $3.25 million.

If buyers see a multiple of 5 as fair, the enterprise value is about $16.25 million. If concentration in a few customers or heavy reliance on the founder pushes the multiple to 4, it is $13 million. That gap is why the next two sections matter more than the arithmetic.

Enterprise value is usually quoted on a cash-free, debt-free basis. What reaches the seller also depends on the debt paid off at closing, cash left in the business, the working capital target, taxes, fees and how the price is paid, such as cash at closing, an earnout or seller financing.

Add-backs: where value is won and lost

Every dollar added back to earnings is worth the multiple. In the example above, the $250,000 of add-backs is worth over $1 million of price at a multiple of 5. That is why buyers test every one of them in diligence.

Add-backs that tend to hold up are documented and clearly non-recurring or owner-specific: one-time legal or restructuring costs, owner compensation above market rate, personal expenses run through the business, and costs that end at closing. Add-backs that tend to fail are expenses the business will keep needing, such as a contractor who does real work, deferred maintenance, or marketing that was cut to inflate the year’s profit.

A slightly lower adjusted figure that survives diligence is worth more than an aggressive one that collapses, because a rejected add-back costs the multiple and the buyer’s trust. For a full list and how to document them, read owner add-backs for SDE.

What moves the multiple

Two businesses with the same earnings can sell at very different multiples. Buyers price risk, and these are the factors they weigh most:

  • Growth: a business growing steadily, with a believable plan to keep growing, is worth more than one that has flattened or depends on one good year.
  • Recurring revenue: contracts, subscriptions and repeat customers give a buyer visibility. Project revenue that must be won again every year is riskier.
  • Customer concentration: if a few customers make up a large share of revenue, losing one after the sale would hit the buyer hard. See customer concentration risk.
  • Owner dependence: if the founder holds the key relationships, knowledge or sales, a buyer is paying for something that may leave at closing. See founder key-person risk.
  • Margins and their quality: healthy, stable margins that do not depend on deferred investment.
  • Clean, verifiable financials: monthly statements that tie to tax returns and bank records shorten diligence and support the multiple.
  • Size: larger businesses generally attract more buyers and carry less key-person risk, which tends to support higher multiples.

The six business value drivers go deeper on how each one moves a business up or down its range.

Strategic and financial buyers price differently

Financial buyers, such as private equity firms, search funds and family offices, value the business on the cash flow it produces as a standalone company, the risk around it, and the return they need on their investment. That view is the baseline for underwriting the business. It is not a guaranteed minimum.

Strategic buyers, usually companies in your industry or an adjacent one, may also count what the business is worth inside their own: cost savings, customers they can cross-sell, a product they no longer need to build. When those benefits are real, a strategic buyer can sometimes pay more than a financial buyer would. That upside is conditional. It has to be proven through competition between buyers, and no buyer owes it to you.

This is why a credible valuation shows the financial view and, where strategic buyers exist, the strategic view as separate cases rather than one blended number.

How to get a range for your business

  1. Gather three years of financial statements and the trailing twelve months, with tax returns that tie to them.
  2. Build an add-back schedule with the reason and evidence for each adjustment.
  3. Choose SDE or adjusted EBITDA based on how the business is run today.
  4. Apply a range of multiples, not a single one, and widen the range for the risks a buyer will see.
  5. Cross-check against revenue multiples and any comparable sales you can find.

Common questions

What is the most common way to value a small business?

A multiple of earnings: SDE for an owner-run business, adjusted EBITDA for one with a management team. Buyers then cross-check it against revenue multiples and comparable sales.

Is my business worth what a valuation says?

A valuation is an estimate of what buyers are likely to pay. The actual price is set by the buyers who show up, how many compete, and the terms they offer. That is why a range, tested against real buyer interest, is more useful than a single number.

Do I need a formal appraisal to sell my business?

Usually not for the sale itself, because buyers do their own analysis. A formal appraisal from a credentialed appraiser is typically tied to tax, estate, legal or lending needs. For planning a sale, an advisory estimate grounded in how buyers price businesses like yours is the more useful starting point.

How can I raise the value before I sell?

Work on what moves the multiple: document your add-backs, reduce reliance on yourself and on your largest customers, grow recurring revenue, and get monthly financials that tie to your tax returns. Read how to increase business valuation before a sale for a fuller plan.
