How to Value a Family Business for Sale or Transfer

The Three Valuation Methods

Business valuation is not a single calculation. It is a range of estimates produced by different methods, each of which reflects different assumptions about what a business is worth to whom.

The income approach values a business based on its ability to generate earnings. For small businesses, the most common income metric is Seller's Discretionary Earnings (SDE): net income plus the owner's salary, plus non-cash charges (depreciation, amortization), plus any personal or one-time expenses the owner ran through the business. The SDE multiple reflects how many years of that earnings stream a buyer is paying for.

The market approach compares the business to similar businesses that have recently sold. BizBuySell, DealStats, and the Pratt's Stats database publish comparable transaction data. Market approach is more reliable when there are enough true comparables; for unusual businesses or thin markets, it is less useful.

The asset approach values the business based on net asset value: the fair market value of all business assets minus all liabilities. This is typically the floor for a business that is barely profitable or being wound down. A profitable going concern is almost always worth more than its net assets.

Most small business transactions ultimately price on the income approach, with the asset approach setting a floor and market comparables providing a sanity check.

SDE Multiples by Industry

The multiple applied to SDE varies significantly by industry, growth rate, customer concentration, and owner dependence. Businesses where the owner is the primary service provider (a solo law firm, a one-person consulting practice) command lower multiples because the earnings are not transferable. Businesses with recurring revenue, documented customer contracts, and a management team in place command higher multiples.

A business with $200,000 in SDE in the auto repair category would typically price between $400,000 and $600,000. If the owner is critical to every customer relationship, expect the lower end. If the business has documented repeat customers and trained technicians who can run without the owner, expect the upper end.

What the SBA Requires for Family Transfers

For any business acquisition between related parties (parent and child, spouses, siblings), SBA Standard Operating Procedures (SOP 50 10 7.1) require a third-party business valuation from a Certified Business Appraiser (CBA), Certified Valuation Analyst (CVA), or Accredited Senior Appraiser (ASA). The appraiser must be independent of both buyer and seller.

The appraisal confirms that the purchase price is at or near fair market value. The SBA's concern is identity-of-interest transactions where family pricing produces an artificially low purchase price, creating a loan secured by collateral that does not actually support the debt.

If the family wants to offer a below-market price (a gift element), that can be structured separately from the SBA loan. The SBA loan must be based on the appraised fair market value. Gift-of-equity elements between family members may require gift tax reporting depending on the amount.

Appraisal costs are typically financed into the SBA loan as a closing cost. Buyers who skip the appraisal to save $5,000 almost always cause the SBA approval to collapse during underwriting. Get the appraisal first.

What Most Articles Get Wrong About Business Valuation

Most valuation articles treat the SBA-ordered appraisal as the definitive price. It is not. It is the floor for the SBA loan amount — and SBA appraisers are trained to be conservative.

The SBA appraiser's mandate is to protect the government guarantee from over-collateralization. They are not pricing what a motivated strategic buyer from within the industry would pay. A competitor acquiring your business to eliminate you can justify paying 15% to 25% above the SBA appraisal because of synergies the appraiser cannot model. An owner who anchors to the SBA appraisal and markets only to SBA-financed buyers may leave meaningful value on the table.

This gap also creates a legitimate negotiating position in family transfers. If the family agrees that the full market value (what a strategic buyer would pay) is higher than the SBA appraisal, the difference can be structured as a seller note or a gift-of-equity — reducing the third-party loan needed while reflecting the actual economic value.

Second common error: conflating SDE with EBITDA. Most small business brokers use SDE; most M&A advisors use EBITDA. For the same business, SDE is always higher because it adds back the owner's salary. A $300,000 EBITDA business where the owner pays themselves $150,000 has $450,000 in SDE. Using EBITDA multiples on an SDE number, or vice versa, produces wildly wrong valuations.

Qualified Appraisers for Family Business Transfers

The SBA requires one of three specific credentials for business appraisers on related-party transactions.

Certified Business Appraiser (CBA) — issued by the Institute of Business Appraisers (IBA). The IBA's member directory at bizappraisers.org lists active CBAs by state.

Certified Valuation Analyst (CVA) — issued by the National Association of Certified Valuators and Analysts (NACVA). Directory at nacva.com. CVAs are common in accounting-adjacent advisory firms.

Accredited Senior Appraiser (ASA) in the business valuation discipline — issued by the American Society of Appraisers. Directory at appraisers.org.

Verify your chosen appraiser's designation directly with the issuing organization before engaging. SBA lenders will review the appraiser's qualifications as part of loan approval, and a disqualified appraiser forces a redo.
