6 Business Valuation Methods Every Business Owner Needs To Know

Most business owners price their company once in a lifetime, which means you rarely get a second chance to land on the right number. In 2025, the median small business sold for $350,000 at a median SDE multiple of 2.57x, but that figure only becomes meaningful once you know which valuation method fits your situation.

This article covers six valuation methods commonly used in small and mid-market business sales, how each one works with formulas and real examples, and how to choose the right approach based on revenue level and ownership structure.

In brief:

• The median small business sold for $350,000 in 2025 at a 2.57x SDE multiple, but the number that applies to you depends on which valuation method fits your company's size and structure.
• Businesses under $2M in revenue typically use SDE-based valuation; businesses above $2M with hired management shift to EBITDA multiples or discounted cash flow.
• Market comparison validates your asking price against actual closed transactions; BizBuySell tracked 9,586 deals in 2025 with a median sale price of $350,000.
• Asset-based and book value methods serve as valuation floors for asset-heavy or low-profit businesses; DCF works best for stable, predictable revenue streams.
• Running at least two valuation methods and cleaning up financials 12–24 months before listing can meaningfully improve the final sale price.

6 valuation methods to price a business for sale

Each valuation method answers a slightly different question about what a business is worth, and the right one depends on revenue level, industry, and the business's owner dependence.

Companies with revenue under $2M typically use SDE-based methods, while those above that threshold often shift to EBITDA or discounted cash flow models. Running two or three in parallel often shows where the value range starts to converge.

The table below gives a quick comparison of all six approaches before the detailed breakdown:

Each method has trade-offs worth knowing before settling on a number.

1. SDE multiple

SDE recasts your income statement to show the full economic benefit a working owner would take home. It's the preferred metric for owner-operated businesses.

The formula is:

• Business value = SDE x Industry Multiple

The industry multiple is the variable that connects your earnings to a market-driven price. It reflects what buyers are actually paying for businesses like yours, derived from comparable closed transactions in your sector.

Multiples vary based on growth rate, customer concentration, recurring revenue, and industry stability.

To calculate your SDE, start with pre-tax net income and add back:

• Interest expense: Payments on business loans or credit lines, a new owner may not carry forward
• Depreciation and amortization: Non-cash charges that reduce taxable income but don't represent actual cash outflows
• Owner's salary and benefits: Total compensation paid to the owner, including health insurance and retirement contributions
• Discretionary personal expenses: Costs such as a personal vehicle or travel that a new owner wouldn't incur
• Non-recurring costs: One-time expenses like lawsuit settlements or major repairs that won't repeat under new ownership

Those add-backs turn a tax-oriented income statement into an earnings figure buyers can compare across businesses. For example, a salon generating $25,000 in pre-tax profit with $10,000 in depreciation, $2,000 in interest, and $21,000 in owner compensation has an SDE of $58,000. Multiplied by a 2.5x industry multiple, this produces an estimated value of roughly $145,000.

Best for: Owner-operated businesses like retail shops, restaurants, and professional practices with revenue under $2M, where you work in the business daily.

2. Earnings multiplier (EBITDA multiple)

EBITDA, or Earnings Before Interest, Taxes, Depreciation, and Amortization, measures what your business earns independent of any single owner's involvement. This metric applies to companies with a hired management team, where the business doesn't depend on the owner's personal effort to generate revenue.

SDE includes the owner's total compensation in the earnings base, whereas EBITDA strips it out, which is why the two metrics are appropriate for different company profiles.

The formula follows the same structure:

• Business value = EBITDA x Industry Multiple

If your company generates $800K in EBITDA at a 5x multiple, the implied value is roughly $4M. Per IBBA Q3 2025 data, median EBITDA multiples ran 4.0x at $2M–$5M and 6.5x at $5M–$50M.

Best for: Businesses with $1M to $50M in revenue that have professional management teams and where the owner's involvement is separable from daily operations.

3. Market comparison (comparable sales)

Market comparison works like real estate comps for businesses. A buyer identifies recently sold companies in the same industry, calculates the pricing multiples implied by those deals, and applies them to the target business's financials.

Looking at comparable sales data gives a benchmark that accounts for differences in revenue, cash flow, and deal size across transactions.

The formula is:

• Business value = Your SDE (or Revenue) x Multiple from comparable sales

For example, if comparable coffee shops sold at 2.8x SDE and the business has an SDE of $120K, the implied market value is roughly $336K. Start by pulling comparable sales data, then assess how the business compares on growth, margins, and customer concentration before applying the multiple.

Best for: Profitable, ongoing businesses in industries with active transaction histories, especially when you want to validate a number from another method.

4. Asset-based valuation

Asset-based valuation prices a business as the sum of its individual parts: total assets minus total liabilities. This approach accounts for both tangible and intangible assets, including equipment, inventory, real estate, intellectual property, trademarks, and customer lists.

The formula is:

• Business value = Total assets - total liabilities

Two variants exist: the going concern version uses the net balance sheet value, assuming you'll keep operating, and the liquidation version estimates what assets would fetch if sold immediately.

For instance, a manufacturing shop with $1.2M in equipment, $300K in inventory, and $400K in liabilities has a going concern value of $1.1M. This method is a valuation floor that ignores future earning potential, so treat it as a starting point rather than a final number.

Best for: Businesses that are closed or liquidated, asset-heavy operations such as manufacturing or equipment rental, and companies with low or negative profitability where earnings-based methods don't yield meaningful results.

5. Discounted cash flow (DCF)

Discounted cash flow (DCF) is one of the most rigorous and complex valuation methods. DCF estimates what your business is worth today by projecting future cash flows and discounting them back to present value using a rate that reflects risk. A dollar received three years from now is worth less than a dollar today because of inflation, risk, and opportunity cost.

The formula is:

• DCF = CF₁/(1+r)¹ + CF₂/(1+r)² + ... + CFₙ/(1+r)ⁿ

Where CF is the projected cash flow for each year, r is the discount rate, and n is the number of years projected. Three inputs drive the output: projected free cash flows, the discount rate, and terminal value.

For a business generating $400K in year-one free cash flow growing at 5% annually with a 15% discount rate, the total DCF value comes out to roughly $4.0M. Small changes in the discount rate can significantly shift the final number.

Best for: Businesses with predictable, stable cash flows like subscription models and established service contracts, and situations where a simple multiple wouldn't capture above-average growth prospects.

6. Book value

Book value is one of the quickest valuation estimates available, though it's typically less accurate than methods that adjust assets to current market value or factor in earnings. It equals total assets minus total liabilities as recorded on your balance sheet, representing what would remain for owners if the business were liquidated at accounting values.

The formula mirrors asset-based valuation on the surface:

• Book value = Total assets - total liabilities

The key difference is that book value uses historical accounting costs from the balance sheet, while a full asset-based valuation adjusts those figures to current fair market value.

For example, a piece of equipment purchased for $200K five years ago might show $80K on the books after depreciation but sell for $140K on the open market. Because book value excludes earning power, brand equity, and customer relationships, it can significantly understate true worth.

Best for: Establishing a minimum valuation floor, tax and estate planning, and quick preliminary estimates before committing to a more thorough analysis.

How do you choose the right valuation method for your business?

The right method depends on three factors:

• Your revenue level
• How owner-dependent is your business
• What kind of earnings does it generate

If you're running an owner-operator business under $2M in revenue, SDE and a market comparison typically produce the most defensible range. For businesses above $2M with a management team in place, EBITDA multiples and a DCF analysis provide buyers with a clearer picture of true earnings power.

However, a few principles hold across the board:

• Use at least two methods: Triangulating between an earnings-based method and a market comparison helps protect against the blind spots of any single approach.
• Clean financials first: Buyers put more weight on verified financial statements and may discount a business with messy or inconsistent records.
• Know the add-backs: Every legitimate dollar added back to SDE or EBITDA directly multiplies into the sale price, so document owner compensation, personal expenses, and nonrecurring costs with receipts and invoices.
• Get a professional opinion: A credentialed appraiser (ASA, CVA, or ABV designation) typically runs several thousand dollars for a summary report and considerably more for a comprehensive certified valuation, which can be a small fraction of the value left on the table without one.

What someone will pay reflects the real valuation, and your preparation determines whether that number lands at the top or bottom of the market range. Businesses with clean data, defensible multiples, and documented add-backs are in a much stronger negotiating position.

Start by identifying whether your business fits an SDE or EBITDA framework, run a market comparison to cross-check the numbers, and clean up your bookkeeping well before listing.

Frequently asked questions about how to price a business for sale

What is the most common way to value a small business?

The SDE multiple method is the most common approach for smaller owner-operated businesses. It measures the full economic benefit to a working owner and applies an industry-specific multiple. In practice, many owners use it as a starting point and then compare it against market data from comparable sales.

Should I get a professional business valuation before selling?

A professional appraisal makes sense for most business sales and is required for SBA loans, estate and gift tax filings, and certain legal disputes. A credentialed appraiser produces a defensible number that holds up during buyer due diligence and can prevent low-ball offers based on incomplete analysis.

What is the difference between SDE and EBITDA?

SDE includes the owner's total compensation in the earnings base, while EBITDA does not. Smaller owner-operated businesses typically use SDE, while larger businesses with management in place use EBITDA. Mixing them up can distort your valuation because each metric is designed for a different type of company.

How far in advance should I prepare my business for sale?

Starting 12 to 24 months before listing gives you time to clean up financial records, document add-backs with supporting evidence, and build a track record of normalized earnings. That runway also helps you address issues that reduce multiples, such as owner dependence or inconsistent financial records.
