One of the most common mistakes first-time business buyers make is letting the seller's asking price anchor their thinking. The seller names a number, the buyer treats it as a starting point, and negotiations begin from a position of ignorance. You do not know if the price is fair, too high, or a genuine bargain because you do not yet have a framework for what the business is actually worth.
Valuing a small business is not as complicated as sellers and brokers sometimes make it sound. There are two metrics that drive the overwhelming majority of small business valuations: Seller's Discretionary Earnings (SDE) and EBITDA. Master these two concepts and you will be able to walk into any deal, look at three years of financials, and know within minutes whether the price makes sense.
This is not theory. This is the framework that professional acquirers, private equity firms, and sophisticated individual buyers use on every deal. Let us build it from the ground up.
Why Standard Accounting Numbers Do Not Tell the Full Story
The first thing you need to understand about small business valuation is that the net income figure on a business's tax return is almost never the right number to use as a baseline. Small business owners have a powerful incentive to minimize taxable income, which means they run as many legitimate personal and discretionary expenses through the business as possible.
The owner might run their personal vehicle through the business. They may take above-market compensation, or below-market compensation if they are trying to make the business look profitable for a sale. They might pay family members who are not essential to operations. They may have one-time expenses that are not recurring. The raw net income figure captures all of this noise, which means it is a poor indicator of what the business actually earns.
This is why we recast the financials. Recasting is the process of adjusting reported earnings to reflect what the business would actually earn in the hands of a new owner. It removes the seller's personal decisions from the picture and replaces them with a clean, normalized view of the business's economic output.
Seller's Discretionary Earnings: The Right Metric for Small Businesses
SDE is the most commonly used valuation metric for businesses with annual revenues under approximately $5 million and owner-operated structures. The formula is straightforward:
SDE = Net Income + Owner's Compensation + Add-backs
Let us walk through each component.
Net income is the starting point. You pull this from the business's tax returns or profit and loss statements. You want three years of data, not just the most recent year. A single good year can be an outlier. Three years tells you whether you are looking at a sustainable earnings trend, a business that is growing, or one that is declining.
Owner's compensation gets added back because in a small business, the owner's salary is often mixed with the return on ownership. If you are buying the business to run it yourself, you will pay yourself a salary too. If you are hiring a manager to run it, you will pay that person a market-rate salary. Either way, the owner's compensation in the historical financials is a personal decision that does not reflect the business's underlying earning power. Add it all back: salary, payroll taxes on that salary, any health insurance or benefits paid for the owner personally.
Add-backs are discretionary or one-time expenses that a new owner would not incur. Common add-backs include personal vehicle expenses, personal travel that ran through the business, above-market rent paid to a related entity, one-time legal fees or equipment purchases, and personal cell phones or subscriptions. Each add-back must be documented and defensible. If you cannot explain exactly why it should be excluded from the normalized earnings figure, do not add it back.
Once you have calculated SDE, you apply a multiple to arrive at a valuation. SDE multiples for small businesses typically range from 2x to 4x, with most deals clustering between 2.5x and 3.5x. The multiple reflects risk, quality, and growth trajectory. A business with stable cash flow, no customer concentration, documented systems, and a clear path to growth commands a higher multiple. A business that depends entirely on the owner's relationships, serves a single large customer, or operates in a declining industry gets a lower multiple.
EBITDA: The Metric for Larger or Manager-Run Businesses
As businesses grow in size or become more institutionalized, the valuation framework shifts from SDE to EBITDA. EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It is a measure of operating profitability that strips out financing decisions (interest), tax strategies (taxes), and non-cash accounting items (depreciation and amortization).
The formula:
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization
EBITDA is typically applied to businesses generating more than $500,000 in owner earnings, or to businesses where the owner does not work in the business day-to-day. The key difference from SDE is that EBITDA does not add back the owner's compensation, because at this scale the business presumably has professional management in place or will require a hired manager.
Multiples for EBITDA tend to be higher than SDE multiples because larger businesses generally carry less risk. A business doing $2 million in EBITDA is more institutionalized, has more customers, more systems, and more redundancy than a business doing $300,000 in SDE. Small business EBITDA deals typically trade at 3x to 6x, with lower middle market transactions ranging from 5x to 8x or higher.
"The asking price tells you what the seller wants. SDE tells you what the business is actually worth. Never confuse the two."
Working Through a Real Example
Let us apply this framework to a concrete scenario. You are evaluating a small landscaping business. The owner is asking $950,000. Here is what the last three years of financials show:
Year 1: $1.2M revenue, $80K net income. Year 2: $1.35M revenue, $95K net income. Year 3: $1.4M revenue, $110K net income.
At first glance, you might think: $110K net income times a 3x multiple equals $330K. The seller is asking nearly three times that. Walk away, right?
Not so fast. You request the add-back schedule and discover the following: the owner pays himself a $180K salary. He runs a personal vehicle through the business at $18K per year. He contributes $22K annually to a personal retirement account through the business. There was a one-time equipment replacement in Year 2 of $35K that is not recurring. Personal travel and meals charged to the business total $12K per year.
Now recalculate. Year 3 SDE = $110K net income + $180K owner salary + $18K vehicle + $22K retirement + $12K personal expenses = $342K. The equipment add-back in Year 2 was a one-time item so we exclude it from the normalized figure.
At a 2.75x multiple, this business is worth approximately $940K. The seller's asking price of $950K is actually quite reasonable. You are not overpaying. In fact, if you can negotiate the deal down to 2.5x, you are buying it at $855K and leaving real money on the table for the seller.
This is the power of knowing the framework. Without it, you either walk away from a fair deal or overpay for a bad one. With it, you can evaluate any business with confidence.
Red Flags in the Add-Back Schedule
Not every add-back is legitimate, and sophisticated sellers sometimes inflate the add-back schedule to make the business appear more profitable than it is. Here are the most common red flags to watch for during due diligence:
Add-backs that are actually operational expenses. If the owner claims that certain travel expenses are personal and should be added back, but those trips were actually client visits or industry conferences necessary to run the business, those are not valid add-backs. A new owner will incur the same expenses.
Employee reclassification. Some sellers will reduce headcount or reclassify employees as contractors in the year before a sale to improve the financials. Look at historical headcount and payroll expenses across all three years, not just the most recent one.
Revenue timing manipulation. A seller motivated to close before year-end may accelerate revenue recognition or defer expenses to make the trailing twelve months look as strong as possible. Compare quarterly patterns across years to spot anomalies.
One-time revenue that is actually one-time. If Year 3 includes a large contract that is not expected to recur, that revenue should be adjusted out of the normalized earnings just as one-time expenses are. Fair recast goes both ways.
Inflated add-backs without documentation. Every add-back should be traceable to a specific line item on the financials or a bank statement. If the seller cannot show you the documentation for an add-back, do not accept it.
The Multiple Negotiation: Where Real Value Is Created
Once you have validated the SDE or EBITDA figure, the negotiation shifts to the multiple. This is where buyers have the most leverage and where the most value can be captured or lost.
Multiple compression is the term for negotiating the seller down from their implied multiple to a lower one. A seller asking 3.5x who accepts 2.75x has compressed the multiple by 0.75x. On a business doing $300K in SDE, that difference is $225,000 in purchase price.
To negotiate the multiple down, you need to articulate specific risks. Customer concentration is the most powerful lever: if 40% of revenue comes from a single customer, the business is riskier and deserves a lower multiple. Owner dependency is another: if the owner is the face of the business and holds all the key relationships, there is real transition risk that should be priced into the deal. Declining industry dynamics, lease risk, regulatory exposure, and deferred maintenance are all legitimate grounds for multiple compression.
To negotiate the multiple up, or to justify paying a premium, you need to be able to articulate why this specific business warrants it. Proprietary systems, recurring revenue, diversified customer base, strong local brand, and documented processes are all multiple expanders.
Putting It All Together
Here is the four-step valuation process I use on every business I evaluate:
Step 1: Get three years of financials. Tax returns, P&L statements, and bank statements. Do not work from projections or seller-prepared summaries alone. Verify the numbers against source documents.
Step 2: Calculate normalized SDE or EBITDA. Use SDE for owner-operated businesses under $5M in revenue. Use EBITDA for larger or professionally managed businesses. Document every add-back and verify it against the financials.
Step 3: Determine the appropriate multiple range. Research comparable transactions in the industry. Consider customer concentration, owner dependency, revenue trends, lease terms, and competitive dynamics. Establish a low, mid, and high multiple scenario.
Step 4: Compare to the asking price. If the asking price falls within your valuation range, the deal is worth pursuing. If it exceeds your high case, negotiate or walk. If it is below your low case, you may have found a genuine opportunity.
This framework will not make every deal analysis easy, and it will not eliminate the need for good judgment and industry knowledge. But it will ensure you are never making a multi-six-figure decision based on gut feel or a seller's asking price. You will know what the business is worth before you sit down to negotiate.
That is the buyer's advantage. And it is available to anyone willing to learn the framework.
