5 Business Valuation Methods Every Owner Should Know [2026]

The Income Approach

The income approach values a business based on the economic benefit it produces for its owner. It is the most widely used approach for small and mid-market businesses because it directly answers the buyer's core question: "How much money will this business put in my pocket?" The three primary income-based methods are SDE multiples, EBITDA multiples, and discounted cash flow analysis.

The SDE multiple methodis the standard for owner-operated businesses under $5 million in revenue. Seller's discretionary earnings represent the total financial benefit available to a single owner-operator: net income plus owner compensation, personal expenses, one-time costs, depreciation, amortization, and interest. The SDE is then multiplied by an industry-specific multiple — typically 1.5x to 4.0x — derived from comparable transaction data. For a restaurant with $250,000 in SDE and a median industry multiple of 2.3x, the estimated value is $575,000.

The EBITDA multiple method is the preferred approach for larger businesses with professional management, private equity acquisitions, and mid-market transactions. EBITDA does not add back the owner's salary because the business requires a paid manager. EBITDA multiples are higher than SDE multiples (typically 3x to 12x) because EBITDA is a smaller number. For a deeper comparison, see our SDE vs EBITDA guide.

The discounted cash flow (DCF) method projects future cash flows over a 5 to 10 year period and discounts them back to present value using a required rate of return. DCF is most useful for high-growth businesses, companies with irregular earnings patterns, or startups where historical multiples are less relevant. The method is theoretically rigorous but highly sensitive to assumptions about growth rates, margins, and discount rates.

The Market Approach

The market approach values a business by comparing it to similar businesses that have recently sold. It operates on the same principle as real estate appraisals: the best indicator of value is what buyers have actually paid for comparable properties. Two methods define the market approach.

The comparable transactions method analyzes actual sale prices of similar privately held businesses. Transaction databases maintained by business brokers and M&A advisors provide sale-to-earnings and sale-to-revenue ratios organized by industry, size, and geography. This is the most practical market method for small businesses because there is a meaningful volume of private transaction data in most sectors. Our industry valuation pages show current multiple ranges for 52 sectors based on comparable transaction data.

The public company comparables method (also called "guideline public companies") uses valuation ratios from publicly traded companies in the same industry as a benchmark. Because public companies are larger, more liquid, and more diversified than private businesses, a discount for lack of marketability and a size premium are applied to adjust the public multiples downward. This method is more commonly used for mid-market and larger private companies.

The Asset-Based Approach

The asset-based approach values a business by summing the fair market value of all its tangible and intangible assets, then subtracting its liabilities. It is most appropriate for asset-heavy businesses (manufacturing, real estate holding companies, equipment rental), investment holding companies, and businesses being valued for liquidation.

Book value is the simplest asset-based calculation: total assets minus total liabilities as reported on the balance sheet. However, book value often understates true value because it reflects historical cost minus depreciation, not current market value. A piece of equipment purchased for $500,000 and depreciated to $50,000 on the books may have a market value of $200,000.

Liquidation value estimates what the assets would fetch in a forced sale — typically 50 to 80 percent of fair market value. Replacement cost estimates what it would cost to recreate the business from scratch, including equipment, trained workforce, customer relationships, and brand recognition. Replacement cost usually produces the highest value because it includes intangible assets, while liquidation value produces the lowest.

When to Use Each Method

The right method depends on the type of business, the purpose of the valuation, and the available data. Here is a practical decision framework:

For most small business owners, the practical starting point is the SDE multiple method. Our free calculator applies SDE, EBITDA, and revenue multiples simultaneously so you can compare results across all three income-based methods in a single analysis.

Combining Multiple Methods

Professional valuators rarely rely on a single method. The standard practice is to apply two or three methods and then reconcile the results into a single conclusion or range of value. This process, called triangulation, reduces the risk that any one method's limitations distort the final estimate.

A common approach assigns weights to each method based on its relevance to the specific business. For example, a profitable owner-operated HVAC company might weight the SDE multiple method at 60 percent, the comparable transactions method at 30 percent, and the asset-based method at 10 percent. A pre-revenue SaaS startup might weight the DCF method at 50 percent and the revenue multiple method at 50 percent.

When methods produce significantly different values, it usually signals that the assumptions underlying one method are inappropriate. For example, if the SDE method values a business at $800,000 but the asset-based method values it at $1.2 million, the business may be more valuable for its assets than its earnings — suggesting the owner is under-utilizing the asset base or the earnings are temporarily depressed.

Common Valuation Mistakes

Using the wrong earnings metric. Applying EBITDA multiples to an owner-operated business — or SDE multiples to a company with professional management — produces a misleading estimate. Make sure the metric matches the buyer profile.

Applying generic multiples. Using a "rule of thumb" multiple without adjusting for your specific industry, size, and risk factors is the most common error. A 2.5x SDE multiple might be reasonable for a stable landscaping company but dramatically undervalues a SaaS business with 90 percent recurring revenue. Use industry-calibrated multiples from comparable transaction data.

Overvaluing growth projections. Buyers discount future projections because they carry execution risk. A business projecting 30 percent revenue growth is not worth 30 percent more than one projecting 10 percent growth — the buyer will apply a higher discount rate to the aggressive projection, often offsetting much of the difference.

Ignoring risk factors. Two businesses with identical EBITDA can have very different values. Customer concentration, owner dependency, declining margins, and single-product risk all compress multiples. Be honest about your risk profile — buyers and their advisors will discover the truth during due diligence.
