SBA Loan Down Payment Requirements for Buying a Business

The short answer most buyers hear is "10% down." That is a reasonable starting point for an SBA 7(a) acquisition, but it hides three details that change the actual check you write: the 10% is usually calculated on total project cost rather than price, only certain funds count, and part of the requirement can sometimes be met with a seller note that will not be paid for years.

The SBA rules in this guide come from SOP 50 10 8.1 with Technical Updates effective October 1, 2026, which calls the down payment an equity injection. Individual lenders may require more.

Minimum equity injection by transaction type

Most first-time buyers are in the initial acquisition category, which the SOP defines as a transaction that results in a new majority or largest individual owner who was not previously an owner, or an individual employed by the business for fewer than 24 months. For that category, the 10% cannot be reduced or eliminated.

Why total project cost matters

Total project cost includes all costs required to become operational, regardless of the source of funds, except lines of credit and 504 loans. In a typical acquisition, that means the purchase price plus working capital, closing costs, and loan fees that are financed in the project.

That $8,000 difference surprises buyers who budgeted 10% of price. If working capital is funded with a separate line of credit instead, it is excluded from total project cost, which lowers the injection but adds a separate obligation.

Which funds count

Unlimited sources

• Cash that is not borrowed, whether on the business’s balance sheet or from other sources, such as a gift.
• Cash from a personal loan to a guarantor, if repayment can be shown to come from a source other than the business’s cash flow. Salary paid to the owner by the business does not qualify as that source.
• Grants without conditional repayment, clawbacks, or other provisions that could require repayment during the 7(a) loan term.
• Eligible prepaid expenses verified with paid invoices, canceled checks, or bank statements. Fees for education, advisory services, or agent fees paid by the applicant do not count.

Limited sources (no more than half combined)

• Standby debt, including seller debt, that is subordinated and on full standby for the 7(a) loan term.
• Non-controlling minority equity investments, where the investor holds less than 20%, exerts no control, and is not repaid before the SBA guaranty is released.

Limited sources, individually or in the aggregate, may provide no more than half of the required injection. See SBA seller note standby requirements for what full standby involves.

Down payment scenarios

The scenarios below are hypothetical initial acquisitions. Each assumes working capital and closing costs are financed in the project.

When you will need more than the minimum

• The price exceeds the independent business valuation. Debt is limited to the valuation, so the gap needs additional equity.
• The lender’s policy requires more, for example in industries it views as higher risk or when the buyer lacks direct experience.
• Debt service coverage is thin, and a larger injection reduces the loan to a level cash flow can support.
• A quality of earnings review lowers the earnings used for coverage. The SOP requires the lender to reduce the loan accordingly, and additional equity can fill the difference.

Business expansions and owner buyouts

For business expansions and owner buyouts, the lender may reduce or eliminate the 10% if it determines the borrower has sufficient liquidity and working capital to sustain operations after the transaction. The applicant’s balance sheet must not show a negative net worth as of the last fiscal year-end. If the requirement is waived, dedicated permanent working capital cannot be included in this or any other 7(a) term loan within 90 days, and working capital must come from existing cash or a line of credit. Our deal structures guide includes a partner buyout example.

Do not spend every dollar on the injection

Meeting the minimum is not the same as being well capitalized. Many lenders want to see personal liquidity left over after closing, and a business owner without a cash cushion has no room for a slow month. Budget for the injection, closing costs that are not financed, and a personal reserve.

Showing sellers and brokers your down payment

Brokers often want evidence that a buyer can cover the cash portion before sharing confidential financials. That is a different question from lender approval. Our guides on proof of funds vs. prequalification vs. preapproval and proof of funds without oversharing explain what to provide at each stage. With a free BuyerPass profile, a broker can request proof of funds verification for a specific opportunity, and the result confirms your funds meet the requirement without exposing balances or account numbers.

Worked example: assembling an $83,000 injection

Hypothetical assumptions: the buyer is purchasing a $750,000 business with total project cost of $830,000, so the minimum injection is $83,000. The buyer plans to use several sources. Here is how a lender would likely look at each one under the SOP categories.

This is a legitimate structure, but the home equity line deserves attention. Borrowed funds count only when repayment can be shown to come from outside the business. If the buyer's plan is to pay the line from the salary the business will pay them, it does not qualify, because salary paid by the business is not an outside source.

Retirement accounts and other special cases

Buyers often ask about using retirement savings. Withdrawing funds and paying the tax produces ordinary unborrowed cash. Some buyers instead use a rollover as business startup structure, in which a new company sponsors a retirement plan that invests in the business. Lenders handle those structures under their own policies, and the structure carries IRS and ERISA compliance obligations, so get advice from a specialist and confirm the lender's position before you sign an LOI.

Partners and investors are another common source. A minority investor holding less than 20% who exerts no control and is not repaid before the guaranty is released counts as a limited source. Larger investors are owners, which brings personal guaranty and eligibility requirements into the picture.

Common down payment mistakes

• Budgeting 10% of the purchase price instead of 10% of total project cost.
• Moving money between accounts right before applying, which creates deposits the lender has to trace.
• Assuming any borrowed money counts. A personal loan qualifies only when repayment comes from outside the business.
• Planning for a seller note to cover more than half of the injection.
• Using every available dollar for the injection and leaving no personal reserve after closing.
• Treating fees paid to advisors or for education as prepaid expenses that count toward the injection. The SOP excludes them.

Frequently asked questions

Is the SBA minimum always 10%?

For an initial acquisition, the 10% minimum on total project cost cannot be reduced. Lenders can and sometimes do require more. For business expansions and owner buyouts, the lender may reduce or eliminate it when the conditions described above are met.

Can I buy a business with no money down using an SBA loan?

Not in an initial acquisition. At least half of the required injection must come from unlimited sources such as your own cash or a qualifying gift. A full-standby seller note can supply the other half at most.

Does the down payment go to the seller?

In most deals, the injection, the loan proceeds, and any seller note together fund the purchase price and project costs at closing. Your cash is applied according to the closing statement the lender and escrow agent prepare.

When should I show a broker my down payment?

Usually before you receive the full financial package, and again when you submit an LOI. See our guide to proof of funds for buying a business for what to provide at each stage.
