SBA loan down payment: equity injection rules for 7(a) buyers
A buyer using a Small Business Administration (SBA) 7(a) loan to purchase a business from an outside seller must put in at least 10% of the total project cost, and that minimum cannot be waived. A seller note on full standby can cover up to half of it. The sections below list what counts.
Seller note standby terms and third-party consents are reviewed before closing.

The equity injection by deal type
Appendix 15 sorts acquisitions into four types, and the type sets the rule. For an Initial Acquisition, "the required equity injection cannot be reduced or eliminated," and the injection is 10% of the total project cost: the price, working capital and costs. For an Owner Buyout, the 10% is measured on the purchase price.
Source: SOP 50 10 8.1, Appendix 15, Equity Requirements; Types of Changes of Ownership
- Initial Acquisition: at least 10%, with no reduction or waiver.
- Business Expansion and Owner Buyout: "the Lender may reduce or eliminate this requirement" if the borrower shows enough liquidity and working capital and has no negative net worth. A waiver bars dedicated working capital for 90 days.
- ESOP control purchases (51% or more): "are not subject to the SBA requirement for equity injection."
- Start-ups: Standard 7(a) and 7(a) Small loans to a start-up require 10% of project cost. A start-up has operated one year or less.
- Real estate bought with the business: the lender allocates the equity "on a pro-rata basis," so the 10% covers the building too.

Acceptable and unacceptable sources
Some sources count without limit. Unborrowed cash counts "whether on the business's balance sheet or from other sources (e.g. gift)." A personal loan counts if it is repaid from outside the business, because "the salary paid to the owner by the business does not qualify." Grants with no clawback and verified prepaid expenses also count in full.

Other sources are limited. Full-standby debt, full-standby seller notes and investments under 20% together "may provide no more than half of the required Equity Injection." Fees paid to brokers or agents do not count. The cost the buyer pays for the financial due diligence report, such as the business valuation, does count: "Any funds expended by the Applicant on the report can count toward the equity injection."

Seller standby and the half cap
A seller note counts as equity only if it is subordinated and "on full standby (no payments of principal or interest for the term of the 7(a) loan)." The SOP has no 24-month standby option in this version. Even then, the note is limited by the half cap above, so at most half of the 10% can come from a standby seller note. If the seller note is paid currently, it does not count toward the equity. It counts toward the debt limit and the cash flow test. The standby agreement explainer covers the paperwork.
Source: SOP 50 10 8.1, Appendix 15, Seller Debt; Standby Debt Agreements; Limited Equity Injection Sources
Price above the valuation is a separate matter: "the difference must be made up by equity." SBA debt cannot fund an overpayment, and any extra limited funds used for that gap "must be on full standby."

Verification timing and 7(a) Small and Express
"Lenders must verify the SBA-required equity injection prior to disbursing any loan proceeds." In practice the lender wants a wire or check and about 30 days of statements, because a gift letter alone is not proof.
Source: SOP 50 10 8.1, Section B, Ch. 6, Loan Closing and Disbursement
7(a) Small (up to $350,000) and SBA Express (up to $500,000, 50% guaranty) may finance acquisitions, but "All other applicable Appendix 15 change of ownership requirements continue to apply unless Appendix 15 expressly provides otherwise." So the acquisition injection rules above apply either way. The difference is outside acquisitions: for non-acquisition SBA Express loans, "whether to require an equity injection, is left to the business judgment of the Lender," and verification follows the lender's own practice. Appendix 15 also says Standard 7(a) processing requirements apply to all changes of ownership, so confirm the path with the lender.

What 10% looks like at the median loan
The SBA loan file does not record equity injections, so no figure here is observed. The table is arithmetic. It assumes the median loan is the financed share of the project and the injection is 10% of the total project: project = loan / 0.9, injection = project x 10%. Across all 48,902 acquisition loans (FY2018 to FY2026), the median loan is $645,250.
| Industry | Loans | Median loan | Implied project | 10% injection |
|---|---|---|---|---|
| Full-Service Restaurants | 2,797 | $411,700 | $457,444 | $45,744 |
| Hotels and Motels | 2,310 | $2,621,250 | $2,912,500 | $291,250 |
| Limited-Service Restaurants | 2,222 | $350,000 | $388,889 | $38,889 |
| Beer, Wine, and Liquor Retailers | 1,736 | $650,000 | $722,222 | $72,222 |
| Gasoline Stations | 1,347 | $1,436,000 | $1,595,556 | $159,556 |
| General Automotive Repair | 1,089 | $562,500 | $625,000 | $62,500 |
| Plumbing, Heating, and Air-Conditioning Contractors | 921 | $734,000 | $815,556 | $81,556 |
| All Other Specialty Trade Contractors | 884 | $673,500 | $748,333 | $74,833 |
| Child Care Services | 850 | $763,300 | $848,111 | $84,811 |
| Insurance Agencies and Brokerages | 832 | $720,000 | $800,000 | $80,000 |
Illustrative only. Actual loans can fund less than the full project, lenders may require more than 10%, and the median loan is not a project cost.
What this means for a business acquisition
The injection is a share of everything the buyer needs to become operational, not just the purchase price. The valuation threshold of $350,000, the independent valuation above it, and the Quality of Earnings report at $3 million or more all feed into whether the price is supported, and any price above the valuation comes out of equity. The complete buyer guide walks through these in order.

Questions buyers ask
How much is the down payment on an SBA 7(a) loan to buy a business?
For an Initial Acquisition, the default type for a new buyer, SOP 50 10 8.1 requires an equity injection of at least 10% of total project cost, and it cannot be reduced or eliminated. Lenders may ask for more; the SOP leaves that to each lender.
Can a seller note count toward the equity injection?
Yes, but only if it is subordinated and on full standby, with no payments of principal or interest for the term of the 7(a) loan. Full-standby debt, full-standby seller notes and minority investments under 20% together can cover no more than half of the required injection.
Can I borrow my down payment?
A personal loan can count if it is repaid from outside the business. The SOP says the salary paid to the owner by the business does not qualify as a repayment source. Lenders review the repayment terms of a loan such as a home equity line.
Does a gift count as equity?
Gifted cash counts as unborrowed cash. The lender verifies it before disbursing, and a gift letter alone "is not sufficient evidence of cash injection without corroborating evidence." Expect to show the wire plus about 30 days of statements.
Is the down payment different for SBA Express or 7(a) Small?
For a change of ownership, no. Section B, Ch. 2 says all other applicable Appendix 15 requirements continue to apply to 7(a) Small and SBA Express acquisitions. For non-acquisition SBA Express loans the SOP leaves the injection decision to the lender; for start-ups, Standard 7(a) and 7(a) Small loans require 10%.
What percent down is needed for an SBA loan?
For an Initial Acquisition, an outsider buying 100% of a business, 10% of total project cost, and it "cannot be reduced or eliminated." For a Business Expansion or Owner Buyout the lender may reduce or eliminate it if liquidity and working capital are sufficient and net worth is not negative. A start-up on a Standard 7(a) loan also needs 10% (Appendix 15, Equity Requirements).
