Most business owners have a number in their head. It might be what they need to retire. It might be what a friend got for a similar business five years ago. It might be a rough multiple they heard at a conference or from a broker years ago. Whatever the source, that number often becomes the anchor — even when it has little to do with how buyers actually evaluate a business.
That is a problem.
Valuation is the first real question of any sale. It shapes how you price the business, how you position it, what kind of buyers you attract, and whether you enter the market with credibility. Get it right and you move forward with confidence. Get it wrong and you either leave money on the table or spend months chasing a price the market will not support.
A good valuation does not give you false confidence. It gives you clarity.
Start with what buyers actually buy
Buyers do not buy your effort. They do not buy your years of sacrifice. They do not buy revenue alone.
They buy cash flow.
More specifically, they buy the future cash flow they believe the business can produce after the transaction closes. That is why valuation conversations are centered far more on earnings than on sales.
A business doing $2 million in revenue with $150,000 in true earnings will be valued very differently than a business doing $2 million in revenue with $500,000 in true earnings. Revenue provides context. Earnings drive value.
For most privately held small and mid-sized businesses, that earnings number is expressed in one of two ways: Seller's Discretionary Earnings (SDE) or EBITDA. Which one applies depends primarily on size and structure. Under roughly $3–4 million in sale price, SDE is standard. Above that threshold, buyers typically shift toward EBITDA. The size of your business determines which applies — and knowing before you enter a valuation conversation puts you ahead of most sellers.
How SDE is calculated — a worked example
SDE represents the total financial benefit the business provides to a single owner-operator. It starts with pre-tax net income and adds back items that are either discretionary or specific to the current owner's situation.
Here is what that looks like for a hypothetical service business doing $1.8 million in revenue:
Now the recast. These are the add-backs — expenses that are real on the tax return but would not exist for a new owner, or that reflect the current owner's personal choices rather than true operating costs:
Without the recast, a buyer looking at the tax return sees $275,000 in earnings. With the recast, the true owner benefit is $506,000. At a 2.5× multiple, that is the difference between a $687,500 valuation and a $1,265,000 valuation. Nearly $600,000 in value — created not by changing the business, but by presenting it accurately.
Every add-back must be documented and defensible. Buyers and their accountants will challenge anything that looks inflated. The recast is not a creative exercise. It is an honest accounting of what the business actually produces for its owner.
How EBITDA differs — and when it applies
EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization — is the standard earnings metric for larger businesses, typically those selling above $3–4 million.
The critical difference: EBITDA does not add back owner compensation. It assumes the business requires a full-time manager, and that manager's market-rate salary is a real operating expense. SDE treats the owner's compensation as discretionary because the buyer is expected to be the operator. EBITDA treats it as a cost of doing business because the buyer — often a private equity group or a strategic acquirer — will hire professional management.
Using the same business from above, an EBITDA calculation would look different:
*In this case, the owner's $120,000 salary is roughly at market rate for a general manager, so no adjustment is needed. If the owner were paying themselves $60,000 for a role that would cost $120,000 to replace, the EBITDA calculation would subtract the $60,000 difference.
Notice that SDE for this business is $506,000 and EBITDA is $377,000. Same business, different metric. The multiples applied to each are calibrated accordingly — SDE multiples are lower because the earnings figure is higher. A 2.5× SDE multiple and a 3.5× EBITDA multiple can produce similar valuations. The metric is not the point. The accuracy of the underlying number is.
The three ways businesses are valued
With your earnings figure in hand, buyers apply one of three primary methods to arrive at a number. Understanding all three helps you know which is most relevant — and how to frame your business when the conversation starts.
The Multiple Method. The most common approach in small and mid-market transactions. Buyers apply a market-derived multiple to SDE or EBITDA. For main street businesses under $5 million in sale price, multiples typically range from 1× to 4× SDE. For lower middle market businesses the range shifts toward 3× to 7× EBITDA, depending on size, industry, growth trajectory, and deal structure. The multiple is not arbitrary — it reflects what comparable businesses have actually sold for. This is the method most buyers use in practice, and the one your valuation should lead with.
The Asset Approach. Most relevant when tangible assets drive value more than cash flow — manufacturers, distributors, equipment-heavy operations, or businesses with minimal profitability. Value is determined by fair market value of assets minus liabilities. If your earnings multiple produces a number lower than your asset base, buyers may anchor there instead.
The Market Approach. Cross-references your earnings multiple against comparable transactions in your industry, geography, and size range. It does not produce the valuation independently — it validates or challenges the multiple you are applying. Comp data comes from sources like BizBuySell and DealStats. The stronger your comp set, the more defensible your asking price.
What actually moves the multiple
Two businesses in the same industry with identical SDE will not receive the same offer. The multiple is where qualitative factors get priced. Buyers are paying for certainty — certainty that the cash flow will continue after they take over.
Anything that increases that certainty pushes the multiple up. Anything that introduces doubt pulls it down.
How industry, size, and growth rate affect your range
Multiples are not uniform across the market. Three factors create wide variation in what buyers will pay for a given level of earnings.
Industry. Some industries command structurally higher multiples because buyers perceive lower risk or higher growth potential. A SaaS business with 90% recurring revenue and low churn will trade at a materially higher multiple than a construction company with project-based revenue and seasonal volatility — even if their SDE is identical. Professional services, healthcare practices, and technology-enabled businesses generally trade at the upper end of the range. Restaurants, retail, and manual-labor-intensive businesses tend to trade at the lower end. There are always exceptions, but the pattern holds.
Size. Larger businesses command higher multiples. A business producing $250,000 in SDE might trade at 1.5× to 2.5×. A business producing $1 million in SDE might trade at 2.5× to 3.5×. A business producing $3 million in EBITDA might trade at 4× to 6×. The premium is not arbitrary. Larger businesses tend to have more diversified revenue, less owner dependency, more management depth, and more sophisticated systems. They are less risky to acquire — and buyers pay for that reduced risk.
Growth rate. A business growing at 15–20% annually will support a higher multiple than one that has been flat for three years, even in the same industry at the same size. Growth signals opportunity. Flatness signals a ceiling. Decline signals risk. Buyers do not just buy what the business earns today. They buy what they believe it will earn over the next three to five years. A strong growth trajectory shifts that belief — and the multiple reflects it.
The practical implication: before you anchor on a multiple you found in an industry report, consider where your business sits on all three dimensions. A small, flat, service business in a competitive industry is not going to trade at the same multiple as a mid-sized, growing, technology-enabled business with recurring revenue — even if they share an industry classification.
When you need a formal appraisal — and when you do not
Not every seller needs to hire a professional appraiser. For most owner-operated businesses under $5 million in sale price, a well-built recast with market-derived multiples produces a defensible range that is sufficient for going to market and having productive buyer conversations. That is the work described in this article — and for the majority of sellers, it is enough.
A certified appraisal — performed by a credentialed professional (ASA, CVA, or ABV designation) following recognized valuation standards — is a different level of work. It produces a formal, documented opinion of value that carries institutional and legal weight. Most sellers do not need to commission one. But certain situations require that one exists:
- SBA-financed deals — the lender requires an independent appraisal before approving the buyer's loan. This is a buyer-side cost, not a seller expense. It happens during the deal process, not before the seller goes to market
- Partnership buyouts or divorce proceedings, where a court needs a third-party opinion that can withstand legal scrutiny
- Estate or gift tax planning, where the IRS may require a certified valuation of business assets
- Businesses with significant intangible assets, multiple revenue streams, or unusual structures where a simple multiples-based range is not sufficient
If none of those apply, the seller's job is to build a recast that is thorough, documented, and defensible — and to understand where the business falls within the range of comparable transactions. Spending $5,000 to $15,000 on a formal appraisal before going to market is rarely necessary for a straightforward owner-operated business sale.
One more point on how to present the number. The valuation does not need to be a single figure. In fact, presenting a range is often more credible. A seller who says "the business is worth $1.2 million" sounds like they are selling. A seller who says "based on recast SDE of $480,000 and comparable transaction multiples of 2.3× to 2.8×, I expect the business to trade between $1.1 million and $1.35 million" sounds like they have done the work.
The valuation gap — and what to do about it
A valuation gap is the difference between what the market says your business is worth and what you need it to be worth.
This matters more than most sellers expect, and discovering it late — after you have gone to market — is one of the most expensive mistakes in a sale process. If your business is currently valued at $800,000 but you need $1.2 million to meet your personal goals, that gap is not a dead end. It is information. But only if you have enough time to do something about it.
Common levers include improving margins, reducing owner dependency, adding recurring revenue, diversifying the customer base, and cleaning up the books. None of those happen in a month. Which is why the valuation conversation belongs well before the intended sale date — not two or three months before going to market.
The sellers who close deals they are proud of start with valuation early enough that they still have time to act on what it reveals.
A STRAIGHT ANSWER
A valuation is built from actual tax returns — recast earnings, documented adjustments, three or more years of returns. It produces a range, not a single figure, along with an honest picture of what is driving value and what is holding it back. The sellers who use it as a tool make better decisions. The ones who skip it are guessing — and guessing in a transaction this consequential is not a strategy.
Valuation is the beginning, not the destination
It tells you whether you are ready to sell. It tells you how buyers will view risk. It tells you what work still needs to be done before you go to market.
Done well, valuation brings discipline to the entire process. It gives you a realistic starting point and lets you enter every buyer conversation from a position of knowledge rather than hope.
The owners who close deals they are proud of do not hand that control to someone else. They do the work, understand the numbers, and go to market prepared.
That is where a better outcome begins.
Frequently asked questions
What is the most common valuation method for small businesses?
The earnings multiple method — applying a market-derived multiple to SDE or EBITDA — is the most widely used approach for privately held businesses. It is how most buyers think about value, and it is the method your valuation should lead with.
What is the difference between SDE and EBITDA?
SDE adds back full owner compensation and is used for smaller, owner-operated businesses where the buyer will also be the operator. EBITDA does not add back owner compensation and is used for larger businesses where the buyer will hire professional management. The right metric depends on the size and structure of the business.
How do I know what multiple applies to my business?
Multiples are driven by industry, size, growth rate, and risk factors like customer concentration and owner dependency. Comparable transaction data from sources like BizBuySell and DealStats provides a starting range. Where your business falls within that range depends on the qualitative factors that move the multiple up or down.
Do I need a professional appraisal to sell my business?
Not always. Most owner-operated businesses under $5 million in sale price can go to market with a well-documented recast and a defensible range based on comparable transactions. Formal appraisals are most commonly needed for SBA-financed deals, partnership disputes, or estate planning purposes.
What if my valuation is lower than what I need?
That gap is information, not a dead end. If you have time, the most effective levers are improving margins, reducing owner dependency, diversifying revenue, and cleaning up financials. If you do not have time, you go to market with realistic expectations and focus on running a strong process to maximize the outcome within the range.
