The Short Answer: What Is the Best Way to Value Your Business Before Selling?

There is no single best formula. The most reliable way to value your business before selling is to run the same process a professional buyer or advisor would, using more than one method and reconciling the results into a defensible range:

1. Normalize your earnings into the figure buyers will actually underwrite: Seller's Discretionary Earnings (SDE) for smaller owner-operated companies, or adjusted EBITDA for businesses with a management team.

2. Apply the market approach. Compare your business with recent sales of similar companies to establish a multiple of earnings. For most privately held, profitable companies, this is the primary method.

3. Cross-check with the income approach. A discounted cash flow (DCF) model tests whether the multiple is justified by your expected future cash flow and risk.

4. Check the asset approach. Adjusted net asset value sets a floor, and it becomes the primary method for asset-heavy or underperforming businesses.

5. Adjust for risk. Customer concentration, founder dependency, and weak documentation all reduce what a buyer will pay.

6. Bridge to cash at closing. Debt, transaction costs, escrow, and the working capital peg determine what actually reaches your account.

These three methods (market, income, and asset or cost) are not an advisor's invention. They are the three principal valuation approaches defined in the International Valuation Standards, which professional appraisers use worldwide. The rest of this guide walks through each step.

Why Valuation Is a Risk Assessment, Not a Calculator Output

Most founders begin the exit conversation by typing "how to value a business before selling" into a search bar and landing on a calculator that asks for revenue and returns a number. That number is rarely what a buyer will pay. Buyers are not purchasing your historical performance. They are purchasing the probability that your cash flow continues after you hand over the keys. Every diligence question is a version of the same question: how likely is this to break?

That is why valuation arrives as a range rather than a single figure. The low end reflects a buyer who sees fragility; the high end reflects a buyer who sees durable, transferable earnings. Most of the gap between the two is risk.

Multiples dominate how professionals talk about value. In a survey of investment professionals cited by Michael Mauboussin and Dan Callahan in their 2024 paper Valuation Multiples: What They Miss, Why They Differ, and the Link to Fundamentals, about 93% said they use a market multiples approach. The same paper makes the point every seller should remember: a multiple is shorthand for a full valuation, not a substitute for one. The method is standardized; the inputs are negotiated.

Who sits across the table matters too. A strategic acquirer underwrites synergies and market position. A financial sponsor, such as a private equity firm, underwrites cash flow stability and the path to its own eventual exit. Both are pricing risk; they simply weight different risks.

Step 1: Normalize Your Earnings (SDE vs. EBITDA)

Before any multiple is applied, buyer and seller have to agree on what the earnings actually are. Two standards dominate, and confusing them is one of the fastest ways to misjudge your own value.

Seller's Discretionary Earnings (SDE), in plain terms, is the total financial benefit one full-time owner takes from the business in a year. It starts with pre-tax profit and adds back the owner's entire salary and benefits, interest, depreciation and amortization, and genuine one-time or discretionary expenses. SDE is used for smaller, owner-operated businesses where the buyer is likely to step into the owner's role personally.

EBITDA (earnings before interest, taxes, depreciation, and amortization) measures operating profit before financing and accounting choices. Unlike SDE, a market-rate salary for the owner's role stays in as an expense, because the buyer will have to pay someone to do that job. Adjusted EBITDA is the standard earnings base for middle-market companies with management depth beneath the founder, and it is the figure any serious EBITDA multiple is applied to.

Add-backs are where earnings quality is won or lost. Buyers tend to sort them into three groups:

• Usually accepted: documented one-time legal settlements, non-recurring professional fees tied to a discrete event, owner compensation above market rate

• Scrutinized: related-party rent, family members on payroll, discretionary marketing described as "optional"

• Usually rejected: lifestyle expenses, undocumented cash adjustments, and any "one-time" cost that reappears year after year

A clean, documented add-back schedule supports every number that follows. A weak one undermines confidence in all of them.

Step 2: The Market Approach (Comparable Transactions)

The market approach, in plain terms, values your company by looking at what buyers recently paid for similar businesses. It rests on the principle of substitution: a buyer will not pay more for your company than for a comparable alternative.

Advisors apply it in two ways:

• Comparable (precedent) transactions: a set of closed deals involving companies of similar size, sector, growth profile, and buyer type. For a private company sale, this is usually the most relevant evidence because it reflects what control buyers actually paid.

• Public company comparables: trading multiples of listed peers. These are a secondary reference point and typically need adjusting downward for the scale, diversification, and liquidity advantages public companies enjoy.

The output is a multiple, most often enterprise value divided by EBITDA (EV/EBITDA), or a multiple of SDE for smaller companies. That multiple is then applied to your normalized earnings from Step 1.

EBITDA Multiples in Context: What Published Ranges Can and Cannot Tell You

Founders understandably want a number: "What multiple does a business like mine sell for?" Published multiples from deal databases, broker surveys, and industry reports are useful for setting expectations. They are not a price guarantee, for several reasons:

• They are averages of different businesses. A sector median blends companies with very different growth, margins, and risk. Your multiple depends on where you sit within that spread, not on the midpoint.

• They move with markets. Multiples compress when credit tightens, when buyers reprice risk, or when a sector has absorbed a wave of consolidation. Comparables from eighteen months ago may not support a valuation today.

• Size matters. Larger companies generally command higher multiples than smaller ones in the same sector, because they tend to be more diversified and less dependent on any one person or customer.

• Deal terms change the headline. A high multiple paid partly through an earnout or seller note is worth less than the same multiple paid in cash at closing.

Structural features consistently push multiples up: recurring or contracted revenue, high switching costs, regulatory barriers to entry, and fragmented markets that attract roll-up buyers. Project-based revenue, commodity pricing, customer concentration, and heavy working capital needs push them down.

The practical takeaway: treat any published range as a starting hypothesis to be tested against current transaction data for companies genuinely like yours.

Step 3: The Income Approach (Discounted Cash Flow)

Discounted cash flow (DCF), in plain terms, values a business by estimating the cash it will generate in the future and converting those future amounts into what they are worth today. A dollar received in five years is worth less than a dollar today, and an uncertain dollar is worth less than a certain one. DCF captures both ideas.

A DCF has three main inputs:

1. A cash flow forecast, typically five years of projected free cash flow, built from realistic assumptions about growth, margins, and reinvestment.

2. A discount rate that reflects the risk of achieving those cash flows. For private companies, this usually includes premiums for small size and company-specific risk, which is why the same forecast can produce very different values in different hands.

3. A terminal value that captures all cash flow beyond the forecast period. This is often the largest part of the result, which is why the assumptions behind it deserve as much scrutiny as the forecast itself.

DCF is most useful when future performance will look different from the past, for example a fast-growing company, one coming off an unusual year, or one with a large new contract. Its weakness is sensitivity: small changes to the discount rate or long-term growth assumption move the answer substantially. That is why advisors use it to test whether a market multiple is reasonable, rather than relying on it alone. A simpler variant, capitalization of earnings, divides one year of normalized earnings by a capitalization rate and suits businesses with stable, predictable results.

Even when a buyer quotes a multiple, sophisticated buyers have usually run their own cash flow model behind it. Knowing how your forecast holds up under their assumptions puts you in a stronger negotiating position.

Step 4: The Asset Approach (Adjusted Net Asset Value)

The asset approach, in plain terms, values a business at what its assets are worth minus what it owes. The balance sheet is restated from book values to current market values (real estate, equipment, inventory, receivables), and liabilities are subtracted.

For a profitable operating company, the asset approach usually produces the lowest figure of the three methods, because it ignores the earning power the assets create together. It still matters in three situations:

• Asset-intensive businesses, such as equipment-heavy or real-estate-rich companies, where asset values drive what buyers will pay

• Underperforming businesses, where earnings do not justify a value above the assets themselves

• As a floor in negotiations, establishing a value below which an offer makes little economic sense

Step 5: Apply the Risk Discount (Concentration and Transferability)

Once a buyer establishes a baseline from comparable transactions and cash flow analysis, they begin adjusting for risk. Every identified dependency is a reason to lower the multiple, raise the discount rate, or move more of the price into contingent payments.

Three dependencies draw the most scrutiny:

• Customer concentration. If a handful of accounts drive most of the revenue, the buyer is underwriting those relationships, not your business.

• Founder dependency. When key customers, suppliers, or pricing decisions route through one person, the earnings are personal rather than transferable.

• Supplier or key-employee concentration. A single-source input or one irreplaceable employee creates the same fragility on the cost side.

The 10% line: U.S. accounting rules (ASC 280) require public companies to disclose when a single customer accounts for 10% or more of revenue. Some advisors treat the same 10% line as a starting signal for closer diligence on private companies, though exact tolerances vary by buyer type and sector. Expect a reduced multiple, more of the price shifted into an earnout or escrow, or both.

Transferability is the antidote. Document relationships at the account level, push authority down to your management team, and give the buyer evidence that the business runs without you in the room. That evidence is what separates a defended multiple from a discounted one.

Step 6: Bridge Enterprise Value to Cash at Closing

Enterprise value is not cash at closing. Between the two sits a set of mechanical adjustments, and the working capital peg is the one founders most often overlook until it costs them.

The peg is the normal level of operating working capital (receivables plus inventory, minus payables) that the buyer expects to be delivered with the business. A buyer purchasing a going concern should not have to inject cash on day one to fund operations the price already accounted for. The parties agree a target, measure actual working capital at closing, and adjust the price dollar for dollar against the difference. Deliver less than the peg and your proceeds fall; deliver more and you are reimbursed, provided the mechanism is symmetrical.

Founder tip: Push for the peg to be based on a trailing twelve-month average rather than a single month or a favorable quarter. Seasonal businesses are especially exposed: a peg set at an inventory peak with a closing at the trough can quietly erase a meaningful share of your proceeds.

Model the peg alongside debt payoff, escrow, and transaction expenses early. The number that matters is what reaches your account.

Which Valuation Method Fits Your Business?

Business profile	Primary method	Useful cross-check
Smaller, owner-operated company	Market approach using a multiple of SDE	Asset approach as a floor
Profitable middle-market company with a management team	Market approach using EV/EBITDA comparable transactions	DCF
Fast-growing or changing company	DCF	Market approach
Asset-heavy or underperforming company	Asset approach (adjusted net asset value)	Market approach

In practice, advisors weigh the results of each method according to how reliable its inputs are for your specific business, then present a reconciled range rather than a single number.

Key Takeaways for Maximizing Your Exit Value

• The best way to value your business is to use more than one method. Normalize earnings, anchor on comparable transactions, test with DCF, and check the asset floor.

• Valuation is a negotiated range, not a calculated figure. The spread between the low and high end is driven by earnings quality and demonstrated risk mitigation.

• Know which earnings base applies to you. SDE fits owner-operated businesses; adjusted EBITDA is the standard for companies with management depth. Applying the wrong multiple to the wrong base produces a number no buyer will honor.

• Published multiples are context, not a promise. They vary with size, sector, market conditions, and deal structure.

• Concentration and founder dependency are the most common discounts. A customer at or above 10% of revenue is a common signal for closer scrutiny.

• Add-backs must be documented, non-recurring, and genuinely separable from operations.

• The working capital peg determines cash at closing. Negotiate it on a trailing twelve-month basis and model it before agreeing a headline price.

Rules of thumb set expectations. Current transaction data, a disciplined process, and competitive tension set the price.

Preparing Your Business for Sale with Founders Advisors

A DCF model, a set of comparable transactions, and a defensible add-back schedule are all tools. What determines the outcome is how they are assembled into a case a sophisticated buyer will underwrite, and how that case is tested before any buyer sees it.

Founders Advisors is a Birmingham, Alabama-based merger and acquisition advisory firm that has worked with middle-market companies since 2003. Its sell-side advisory work spans business services, consumer, healthcare, industrials, and technology, and starts with the questions covered in this guide: what your earnings really are, which dependencies a buyer will price against, and how to position the business so the valuation reflects what you have built.

For most founders, price is only part of the outcome. The people who stay, the company's name, and how the buyer treats what you built matter too, and they are shaped by the same preparation.
