Most business owners estimate the value of their company by multiplying their net profit by a number they heard somewhere. That approach produces a number. It does not produce an accurate valuation, and in most cases it significantly underestimates or misrepresents what a buyer will actually pay.
The reason is simple: buyers do not value businesses on net profit. They value them on normalized earnings, using a specific methodology that varies by business size, buyer type, and industry. Understanding how buyers value a business is the prerequisite to understanding what yours is actually worth, and what you can do between now and the transaction to influence that number.
This article covers the three primary business valuation methods buyers use for small businesses, the critical distinction between SDE and EBITDA, what drives the multiple up or down, and how to think about your number before you go to market.
Why Net Profit Is the Wrong Starting Point
Net profit on your income statement is the number your CPA cares about. It is shaped by your accounting choices, your tax strategy, and your ownership structure. It includes your salary, your personal vehicle, the insurance on your lake house, and the legal fee from the dispute you settled three years ago.
A buyer does not care what your net profit was. A buyer cares what the business will earn under their ownership, after replacing your compensation with a market-rate salary, removing your personal expenses, and adding back the one-time items that will not recur. That adjusted number is either your Seller's Discretionary Earnings or your EBITDA, depending on the size of your business and who is buying it. Understanding the difference between those two metrics is the first step in understanding what your business is actually worth.
The Two Earnings Metrics Buyers Use
Seller's Discretionary Earnings. SDE is the metric buyers use for smaller businesses, typically those generating under $5M to $10M in revenue. It starts with net profit and adds back the owner's compensation, owner benefits and perks, depreciation and amortization, interest, and any non-recurring or personal expenses. The result is a single number that represents the total financial benefit an owner-operator will receive from the business.
SDE is the relevant metric when the buyer is an individual or a small operator who plans to work in the business. They need to know whether the business can support their lifestyle and their debt service. SDE answers that question directly.
For a business with $800,000 in net profit, $200,000 in owner compensation, $50,000 in personal vehicle and benefits, and $75,000 in depreciation, the SDE calculation produces roughly $1,125,000. At a 2.5x SDE multiple, the business is worth approximately $2.8M. That is very different from what a net profit multiple would suggest.
EBITDA. EBITDA, earnings before interest, taxes, depreciation, and amortization, is the metric institutional buyers and PE firms use. It reflects the enterprise's operating profitability on a stand-alone basis, assuming a professional management team replaces the owner. EBITDA does not add back owner compensation above market rate. It normalizes for what the business earns independent of who owns it.
EBITDA becomes the relevant metric when the business is large enough that a buyer will install professional management rather than work in the business themselves. The threshold is typically around $5M to $10M in revenue, but the more precise trigger is whether the buyer is an individual or an institution.
Practical rule: Use SDE for businesses under $5M in revenue with an owner-operator buyer. Use EBITDA for businesses above $10M in revenue with institutional or PE buyers. Businesses between $5M and $10M in revenue may have both metrics calculated depending on the buyer type.
Business Valuation Methods: The Three Approaches
There are three primary methods buyers use to value a small business. In practice, most transactions rely primarily on one and use the others as a cross-check.
Method 1: Multiple of SDE or EBITDA. The most common method for private business transactions of any size. The buyer calculates the normalized earnings using SDE or EBITDA, then applies a multiple based on the industry, business quality, and comparable transactions.
The multiple range for most small businesses at the main street level is 1.5x to 3.0x SDE. According to BizBuySell's 2025 data, the average cash flow multiple across all small business sectors was 2.61x. Lower middle market businesses with EBITDA above $1M typically trade at 3x to 6x EBITDA, with well-prepared manufacturing and distribution companies reaching 5x to 8x for quality assets.
The math matters here. At a 3x EBITDA multiple, every $100,000 improvement in normalized EBITDA adds $300,000 to the sale price. At 5x, that same improvement adds $500,000. The multiple is not fixed. It moves based on factors the seller can influence before going to market.
Method 2: Comparable Sales. The market approach looks at what similar businesses have actually sold for and adjusts for differences in size, profitability, and quality. Business brokers and M&A advisors use transaction databases including BizBuySell, DealStats, and Capital IQ to find comparable transactions and derive a supportable multiple range.
The comparable sales method is used as a sanity check on the earnings multiple approach rather than as a stand-alone method for most private transactions. It is more useful when there is a robust set of genuinely comparable transactions in the same industry and size range.
Method 3: Asset-Based Valuation. The asset approach values a business by totaling its tangible assets and subtracting liabilities. It is appropriate for asset-heavy businesses being liquidated, real estate holding companies, or businesses with minimal earnings but significant tangible value.
For most manufacturing and distribution businesses with healthy earnings, the asset-based approach understates value significantly because it ignores the earnings power of the business and the customer relationships behind it. A distribution company with $2M in EBITDA and $5M in assets is worth far more than $5M minus its liabilities. Most buyers will not apply an asset-based approach to a going concern with demonstrable earnings.
Asset value is a floor, not a ceiling. A business with strong, documented earnings is worth a multiple of those earnings, not a liquidation value of what is on the balance sheet.
What EBITDA Multiple Will You Get for Your Business
The multiple your business receives is not determined by the industry median alone. Two businesses in the same industry with identical EBITDA can transact at meaningfully different multiples based on factors the seller controls.
Revenue quality. Recurring revenue commands a higher multiple than project revenue on the same EBITDA. A distribution business with long-term supply agreements and annual service contracts is a different asset than one where every dollar of revenue has to be won on a new project each year. Buyers pay more for predictability because predictability reduces risk, and risk is what the multiple is pricing.
Customer concentration. A single customer representing 30 or 40 percent of revenue is a risk that buyers price into the multiple. The mechanism is either a lower multiple, an escrow holdback tied to that customer's retention, or earnout provisions. Diversifying customer concentration in the 24 months before a transaction directly improves the multiple range a business can command.
Owner dependency. If the business cannot operate without the current owner, a buyer is not acquiring a business. They are acquiring a job with a complicated handover. The more documented the processes, the more capable the management team below the owner, and the more the customer relationships are institutionalized rather than personal, the higher the multiple a buyer will pay for confidence in continuity.
Financial documentation quality. Buyers and their advisors run a quality of earnings process on every acquisition above a certain size. That process tests the financial statements against the underlying records. Clean, timely, well-organized documentation that has been consistent for three years is the baseline that enables a buyer to pay a strong multiple with confidence. Documentation gaps give buyers leverage to reprice.
Size. The relationship between size and multiple is direct and well-documented. A business with $250,000 in SDE will typically transact at a lower multiple than a business with $2M in EBITDA in the same industry, even if the quality metrics are comparable. Larger businesses are perceived as less risky by buyers because they are less dependent on any single person, customer, or contract. This size premium is a real factor in the lower middle market.
How Buyers Value a Manufacturing or Distribution Business
Manufacturing and distribution businesses have specific valuation dynamics that generic frameworks do not fully address.
Inventory is a key variable. Buyers will apply their own methodology to inventory valuation in due diligence. If your inventory costing is inconsistent, your slow-moving reserve is understated, or your records do not reconcile to physical counts, the adjustment happens at the table and comes off the purchase price. Clean inventory records before going to market are a meaningful value protection measure, not an administrative detail.
Working capital is another. Most transactions include a working capital peg, an agreed level of net working capital to be delivered at closing. The peg is set based on your historical working capital, so how you manage receivables, payables, and inventory in the 12 months before closing directly affects the peg. Sellers who understand this optimize working capital management before the transaction window opens.
For manufacturing businesses, the add-back treatment of owner compensation is straightforward when the owner is not critical to operations. It becomes complicated when the owner holds key customer relationships, manages proprietary technical processes, or performs work that would require two or three hires to replace. Documenting these functions and demonstrating a plan for transition is part of the preparation work that supports a strong multiple.

How to Find Out What Your Business Is Worth
There is a difference between an informal valuation estimate and a formal business valuation. Both have their place depending on what you are trying to accomplish.
An informal estimate based on publicly available multiple data and your current normalized EBITDA gives you a reasonable starting range for planning purposes. It is not reliable enough for a transaction, a financing, or a dispute, but it is useful for understanding where you are relative to where you want to be at exit.
A formal business valuation conducted by a Certified Valuation Analyst or a Certified Business Appraiser produces a defensible value opinion supported by market data and a documented methodology. This is what lenders, PE firms, and sophisticated buyers expect in a transaction process. The cost ranges from a few thousand dollars for a calculation of value to $10,000 or more for a comprehensive valuation report.
For most business owners planning an exit in the next two to three years, the right starting point is an honest assessment of your current normalized EBITDA, your multiple range given your industry and quality factors, and the gap between where you are today and where you want to be. That gap analysis is the foundation of the preparation work.

If you are within two to three years of a planned sale, that page describes what the work looks like and how it is structured.
The Multiple Math and Why Preparation Compounds
The reason the 24-month preparation timeline matters for valuation is not just that improvements need time to appear in the financial statements. It is that improvements compound through both levers simultaneously.
A business that increases normalized EBITDA from $1.5M to $1.8M while also improving its multiple from 4x to 5.5x does not simply add $300,000 in earnings value. At $1.5M and 4x, the business is worth $6M. At $1.8M and 5.5x, the business is worth $9.9M. The same $300,000 in EBITDA improvement, amplified by the multiple expansion, produced nearly $4M in additional sale price.
This is not a hypothetical. It is the math behind every well-prepared lower middle market transaction. The businesses that close at premium multiples are the ones that improved both the earnings and the multiple in the preparation window, because those two levers move together when a business demonstrates financial quality, revenue predictability, and management depth.
BizBuySell 2025: Average cash flow multiple across all small business sectors: 2.61x. Businesses that sold at full asking price shared common characteristics: three or more years of clean financial records, organized documentation, and realistic pricing. Prepared sellers consistently outperform unprepared ones on both multiple and time to close.

The Short Version
Business valuation is not a calculation you do once and file away. It is a living number that reflects the current quality of your earnings, your financial documentation, your customer base, and your management depth. All of those factors are movable before you go to market.
The owners who understand the difference between SDE and EBITDA, who know which multiple range their industry supports, and who understand what drives buyers up or down within that range have a significant advantage over the ones who show up to a transaction and learn these concepts for the first time during due diligence.
