How SBA Lenders Value a Business You Want to Buy: What They Look At, How They Calculate It, and What to Do When the Valuation Comes in Low

SBA lenders don’t use the asking price to determine how much they’ll lend. They use an independent valuation based on the business’s historical cash flow, and the loan caps at whatever that valuation produces.

What SBA Lenders Look At When Valuing a Business

The Financial Foundation: Tax Returns, P&L, and Balance Sheet

The valuation starts with the target business’s financial records. The appraiser needs 3 years of federal tax returns, a current year-to-date profit and loss statement, and a balance sheet.

The tax returns establish the baseline. The appraiser looks at revenue trends (growing, flat, or declining), gross margins, net income, and consistency across the 3-year period. A business that earned $400,000 in each of the last 3 years tells a different story than one that earned $600,000, then $300,000, then $500,000. Consistency signals predictability. Volatility signals risk, and risk lowers the valuation.

The P&L provides current-year performance. If the business earned $400,000 annually on the tax returns but is tracking toward $500,000 in the current year, the appraiser may weight the current trajectory more heavily. If it’s tracking toward $300,000, the appraiser will ask why.

The balance sheet shows what the business owns and owes. Tangible assets (equipment, inventory, real estate) have independent value. Accounts receivable represent money owed to the business. Liabilities (outstanding loans, leases, payables) reduce the net asset value. The balance sheet gives the appraiser the asset floor beneath the income-based valuation.

SDE vs. EBITDA: Which One the Appraiser Uses and Why

The appraiser’s first decision is which earnings metric to use. This choice changes the valuation number significantly because the two metrics measure different things.

Seller’s Discretionary Earnings (SDE) is used for owner-operated businesses, typically those earning under $1 million in adjusted earnings. SDE starts with net income from the tax return and adds back the owner’s salary, owner’s personal expenses run through the business, interest, depreciation, amortization, and one-time non-recurring expenses. SDE represents the total economic benefit available to a single owner-operator.

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is used for larger businesses with professional management, typically those earning over $1 million. EBITDA does not add back the owner’s salary because the assumption is that the business will continue to employ a paid manager regardless of who owns it.

The practical difference: a business with $200,000 in net income, an owner salary of $150,000, and $50,000 in depreciation has an SDE of $400,000 but an EBITDA of $250,000. The same business valued at a 3x multiple produces a $1.2 million valuation on SDE but only a $750,000 valuation on EBITDA. The metric used can change the valuation by 40% or more.

Ask the lender which metric their appraiser will use before the engagement starts. If you’re buying an owner-operated business with under $1 million in earnings, confirm that the appraiser is using SDE, not EBITDA.

TIP: We suggest asking the lender or appraiser directly: “Will you be valuing this business on SDE or EBITDA?” If the business earns under $1M in adjusted earnings and is owner-operated, SDE is the appropriate metric. If the appraiser uses EBITDA on a small owner-operated business, the valuation will come in significantly lower because it doesn’t add back the owner’s salary. Confirming the metric before the appraisal starts prevents a valuation gap caused by the wrong calculation, not the wrong business.

What the Appraiser Examines Beyond the Financials

Financial statements tell the appraiser what the business has earned. Non-financial factors tell the appraiser how likely those earnings are to continue under new ownership.

Customer concentration: If one customer accounts for 30% or more of revenue, the appraiser treats that as a risk. Losing that customer could collapse the business’s earnings. High customer concentration pushes the valuation down.

Contract terms and recurring revenue: Businesses with long-term contracts, subscriptions, or retainer agreements have more predictable cash flow than businesses that depend on new sales each month. Predictable revenue raises the valuation. If the business has recurring revenue that wasn’t presented to the appraiser, this is documentation worth providing.

Owner dependency: If the business’s revenue depends primarily on the owner’s personal relationships, reputation, or skills, the appraiser discounts the valuation because that revenue may not transfer to a new owner. A business where the owner does 70% of the sales calls is worth less than one where a sales team handles client relationships independently.

Industry risk: Some industries have higher failure rates, regulatory exposure, or cyclical volatility. Restaurants, construction companies, and retail businesses typically receive lower multiples than professional services firms, healthcare businesses, or recurring-revenue technology companies.

Lease terms: A business operating in a leased space with only 2 years remaining on the lease is worth less than the same business with 10 years remaining. If the landlord can refuse renewal or raise rent dramatically, the appraiser treats that as a risk to future earnings.

When a Credentialed Appraisal Is Required

Not every SBA acquisition loan requires a formal business appraisal. The trigger is the amount of goodwill in the deal.

Goodwill is the difference between the purchase price and the value of the business’s tangible assets. If you’re paying $800,000 for a business with $200,000 in equipment and inventory, the goodwill is $600,000.

When goodwill exceeds $250,000, most SBA lenders require a formal appraisal performed by a credentialed appraiser. Accepted credentials include ASA (Accredited Senior Appraiser), CVA (Certified Valuation Analyst), and ABV (Accredited in Business Valuation). An appraisal from an uncredentialed individual may not satisfy the lender’s requirements.

A formal appraisal costs $3,000 to $10,000 and takes 2 to 3 weeks to complete. If your deal has goodwill above $250,000, engage the appraiser during the first week of due diligence. Waiting until the lender requests it during underwriting adds 2-3 weeks to the timeline.

For deals with goodwill below $250,000, the lender may accept an internal valuation or a broker’s opinion of value rather than a full appraisal. Ask the lender during prequalification whether a formal appraisal will be required for your specific deal.

How SBA Lenders Calculate Business Value

The Income Approach and How Multiples Work

The most common valuation method for SBA acquisition loans is the income approach. The appraiser takes the business’s adjusted earnings (SDE or EBITDA) and multiplies it by a factor that reflects the business’s risk and growth profile.

The formula: Business Value = Adjusted Earnings x Multiple

The multiple for SBA acquisition deals typically ranges from 1.5x to 5.0x. Where a specific business falls within that range depends on the factors covered in the next section.

A business with $300,000 in SDE valued at a 3.0x multiple appraises at $900,000. The same business at 2.0x appraises at $600,000. At 4.0x, it appraises at $1.2 million. The multiple is the single most impactful variable in the entire valuation.

Some appraisals use multiple valuation methods (income approach, market approach, asset approach) and weight them. The income approach almost always carries the most weight in SBA acquisition valuations because the lender’s primary concern is whether the business’s cash flow can service the loan.

TIP: We suggest running a quick estimate before the formal appraisal: multiply the target business’s SDE by 2.0 (low end) and by 3.5 (high end). For most service and retail businesses, the appraised value will land somewhere in that range. If the seller’s asking price is above the high end of your estimate, the appraisal will likely come in below the purchase price. Knowing this early lets you plan for the gap before it becomes a deal problem.

What Drives the Multiple Higher or Lower

The multiple isn’t arbitrary. It reflects the appraiser’s assessment of risk and transferability.

Factors that push the multiple higher (toward 4.0x-5.0x):

• Recurring revenue (contracts, subscriptions, retainers)
• Diversified customer base (no single customer over 10% of revenue)
• Professional management team (business runs without the owner)
• Growing revenue trend over 3 years
• Strong industry fundamentals (healthcare, professional services, B2B software)
• Long-term lease in a favorable location
• Low capital expenditure requirements

Factors that push the multiple lower (toward 1.5x-2.5x):

• Transaction-based revenue (no contracts, each sale is new)
• High customer concentration (one customer over 25% of revenue)
• Owner dependency (revenue depends on owner’s personal relationships)
• Declining or flat revenue over 3 years
• High-risk industry (restaurants, retail, construction in cyclical markets)
• Short lease or unfavorable lease terms
• High capital expenditure requirements (equipment replacement, facility maintenance)

Most SBA acquisition deals for small businesses (SDE under $500,000) land between 2.0x and 3.5x. Businesses with strong recurring revenue and professional management can reach 4.0x or higher. Businesses with high owner dependency and transaction-based revenue often land at 2.0x or below.

The DSCR Constraint: When Cash Flow Caps the Loan Below the Valuation

A high valuation doesn’t guarantee a large loan. The lender sizes the loan based on whether the business’s cash flow can service the debt, not based on the appraised value.

The lender calculates the maximum annual debt service by dividing the business’s net operating income by the DSCR requirement (typically 1.25). If the business generates $300,000 in annual net operating income, the maximum annual loan payment is $300,000 / 1.25 = $240,000. At an 8% interest rate over 10 years, $240,000 in annual payments supports a loan of approximately $1.64 million.

If the business appraises at $2 million but the DSCR only supports a $1.64 million loan, the loan caps at $1.64 million. The buyer must cover the difference with additional equity, seller financing, or a restructured price.

The DSCR and the valuation work as dual constraints. The loan caps at the lower of the two. On most mid-market deals, the DSCR is the binding constraint because the cash flow limits the loan before the valuation does.

TIP: At Small Business Funding, we recommend running the reverse DSCR calculation before you make an offer. Divide the target business’s annual net operating income by 1.25 to find the maximum annual debt service. Use an online loan calculator to convert that annual payment to a maximum loan amount at the current SBA rate and your expected term length. If this number is lower than the appraised value, the DSCR is your binding constraint, and the valuation won’t help you borrow more.

The Value Cap Rule: Lower of Purchase Price or Appraised Value

The SBA requires the lender to cap the loan at the lower of the purchase price or the independently appraised value. This rule works in both directions.

Appraisal below purchase price: If you’re paying $1 million but the appraisal comes in at $850,000, the SBA loan caps at the appraised value ($850,000). You need to cover the $150,000 gap with additional equity or seller financing.

Appraisal above purchase price: If you’re paying $800,000 but the appraisal comes in at $1 million, the SBA loan caps at the purchase price ($800,000). You don’t get to borrow against value you’re not paying for. The good news: an appraisal above the purchase price means you’re getting the business at a discount, which is a positive signal to the lender.

The cap protects the SBA from guaranteeing a loan on an overpriced business. It also creates the most common source of deal friction in SBA acquisitions: the valuation gap.

What to Do When the Valuation Comes in Low

Renegotiate the Purchase Price

The most direct solution is to ask the seller to reduce the price to match the appraisal. This is easier said than done, but it’s the cleanest path to closing.

Frame the conversation around the lender’s requirements, not your opinion of the business’s value. “The bank’s independent appraiser valued the business at $850,000. The SBA won’t guarantee a loan above the appraised value. I’d like to make this deal work, but the financing only supports $850,000.”

Some sellers will accept the lower price rather than lose the deal and restart the process with a new buyer. Others will refuse, especially if they believe the appraiser undervalued the business. If the seller has multiple interested buyers, they have less incentive to negotiate.

If the seller won’t reduce the full gap, propose a partial reduction paired with one of the other strategies below. A $100,000 price reduction combined with a $50,000 seller note is easier for most sellers to accept than a $150,000 price reduction alone.

Increase Your Equity Injection to Cover the Gap

If you have additional cash available, you can increase your equity injection to cover the difference between the appraised value and the purchase price.

On a deal where the appraisal comes in $100,000 below the purchase price, increasing your down payment by $100,000 closes the gap. The SBA loan stays at the appraised value. Your total cash at closing goes up by $100,000.

This is the simplest solution from a deal structure perspective, but the most expensive for the buyer. Every dollar of additional equity injection is a dollar that could have stayed in your reserves for the post-closing transition period. Before committing additional cash, calculate whether you’ll have enough liquid reserves to cover 3-6 months of loan payments after closing.

Bridge the Gap with a Seller Note on Full Standby

A seller note can cover the valuation gap without requiring additional cash from the buyer. The seller carries a note for the difference between the appraised value and the purchase price.

If the appraisal is $850,000 and the price is $1 million, the seller carries a $150,000 note. The SBA loan covers 90% of the appraised value ($765,000), the buyer provides 10% equity injection ($85,000), and the seller note covers the $150,000 gap.

For the seller note to count toward the equity injection (reducing your cash requirement further), it must be on full standby with zero payments for the life of the SBA loan. If the seller won’t accept full standby, the note can still bridge the valuation gap, but it gets classified as junior debt and its future payments get factored into the DSCR calculation.

TIP: We suggest confirming the seller’s willingness to carry a standby note before you commit to a purchase price above the expected appraisal range. If the seller refuses standby terms, the note becomes junior debt, and its payments get added to the DSCR. A $150,000 seller note at 6% over 7 years adds roughly $2,200/month to the business’s debt obligations. That additional payment may push the DSCR below 1.25 and force the deal to be restructured at a lower price anyway.

Challenge the Appraisal with Additional Documentation

If you believe the appraisal undervalues the business, you can request a reconsideration with supporting documentation. This isn’t a guarantee of a higher number, but it’s a legitimate path.

Review the appraiser’s SDE or EBITDA calculation line by line. Look for owner expenses that weren’t added back: personal vehicle payments, personal health insurance, above-market rent paid to a related-party landlord, one-time legal or consulting fees, personal travel expenses run through the business. Each documented add-back increases the adjusted earnings, which increases the valuation.

If the business has recurring revenue (contracts, retainer agreements, subscription clients) that wasn’t presented to the appraiser, provide the documentation. Recurring revenue reduces perceived risk and can push the multiple higher.

Provide a written request for reconsideration to the appraiser through the lender. Include the specific add-backs with supporting documentation (receipts, contracts, personal credit card statements) and any recurring revenue evidence (signed contracts, historical renewal rates). The appraiser reviews the new information and may revise the valuation upward.

The reconsideration process typically takes 1 to 2 weeks. Factor this into your timeline if you’re challenging the appraisal.

TIP: We recommend reviewing the appraiser’s SDE calculation line by line before accepting a low valuation. Look for owner expenses that weren’t added back: personal vehicle ($12,000-$24,000/year), personal health insurance ($8,000-$15,000/year), above-market rent to a related-party landlord ($5,000-$20,000/year), and one-time legal fees. A single missed $20,000 add-back at a 3.0x multiple increases the valuation by $60,000. Document each missing add-back with receipts and submit a written reconsideration request through the lender.

Walk Away: When the Gap Means the Deal Doesn’t Work

Sometimes the valuation gap is too large to bridge. If the appraisal comes in 25% or more below the purchase price, and the seller won’t negotiate, the deal probably doesn’t work under SBA financing.

A $1 million asking price with a $750,000 appraisal means a $250,000 gap. Covering that gap requires some combination of $250,000 in additional equity, a $250,000 seller note, or a $250,000 price reduction. If none of those are available or the combined solution pushes the deal’s economics past the point of profitability, walking away is the right decision.

Walking away from a deal isn’t failure. It’s a financial decision that protects you from overpaying for a business that an independent expert says isn’t worth the asking price. The appraisal is there to protect you, not just the lender.

Frequently Asked Questions

Can I choose my own appraiser for the SBA valuation?

Usually no. The lender selects the appraiser from their approved list to maintain independence. You can ask the lender whether they’ll accept an appraisal you’ve already obtained, but most lenders require their own. If you’ve already paid for a valuation during due diligence, it may serve as a reference but won’t replace the lender’s required appraisal.

How long does the appraisal take and what does it cost?

A formal business appraisal typically takes 2 to 3 weeks once the appraiser is engaged and has received the financial documents. Cost ranges from $3,000 to $10,000 depending on the complexity of the business, the number of locations, and whether the appraisal includes real estate. Engage the appraiser during the first week of due diligence to prevent it from becoming a timeline bottleneck.

If the appraisal comes in above the purchase price, can I borrow the extra?

No. The SBA caps the loan at the lower of the purchase price or the appraised value. An appraisal above the purchase price means you’re getting the business below appraised value, which is a positive indicator for the lender, but the loan amount is still based on the actual purchase price minus your equity injection.

Run the SDE multiple estimate (SDE x 2.0 to 3.5) and the reverse DSCR calculation before you make an offer, so you know the likely valuation range and the maximum loan the business can support.
