SBA equity injection: how much you need to put in, and from where
Short answer
The SBA requires a minimum 10% equity injection for change-of-ownership loans, calculated on total project cost (purchase price plus other uses of proceeds like working capital and closing costs). For an Initial Acquisition it can't be reduced or eliminated.
Unborrowed cash and certain other sources count without limit. Seller debt on full standby and non-controlling minority investors together can provide no more than half of the required injection.
The equity injection is your skin in the game. It's also the number that decides which businesses you can realistically buy, so it's worth understanding precisely.
The minimum by transaction type
| Type | Minimum | Can lender reduce it? |
|---|---|---|
| Initial Acquisition | 10% | No |
| Business Expansion | 10% | Yes, if borrower has sufficient liquidity and working capital and no negative net worth |
| Owner Buyout | 10% (of purchase price) | Yes, same conditions |
| ESOP buying a controlling interest | Not subject to the injection requirement | n/a |
The base is the total project cost plus other uses of proceeds in the loan. Real estate bought with the business is subject to the same injection requirement.
What counts as equity
Unlimited sources
- Unborrowed cash, on the business's balance sheet or from other sources
- Cash from a personal loan to a guarantor, repaid from a source other than the business's cash flow
- Grants with no repayment, clawback or conditions during the loan term
Limited sources (max half, combined)
- Seller debt subordinated and on full standby for the life of the loan
- Investments from non-controlling minority investors (under 20%, no control), not repayable before the guarantee ends
Illustrative example, not a real deal
Total project cost is $900,000, so the minimum injection is $90,000. At most $45,000 can come from a standby seller note and minority investors combined. At least $45,000 must be unborrowed cash or another unlimited source. If you bring $45,000 cash and the seller agrees to a $45,000 standby note, you meet the minimum exactly. If the lender's valuation comes in $50,000 below the price, you'll need another $50,000 of equity, and any additional limited-source money used to cover a gap like that must be on full standby.
Common equity mistakes
- Borrowing the down payment against the business or with a loan repaid from the business. It doesn't count under SBA rules.
- Moving money between accounts just before applying, which creates a paper trail you then have to explain.
- A "gift" that's really a loan with repayment expected. Lenders ask; gift letters must be true.
- Assuming a seller note covers everything. Standby notes and minority investors together can supply at most half of the required injection.
- Forgetting closing costs and working capital, which are part of total project cost and raise the 10%.
- Spending the reserve. The minimum injection isn't the right amount of cash to bring if it leaves nothing for the first slow month.
Documenting your equity
Lenders verify the source of every dollar. Expect to provide bank statements showing the funds have been in your accounts (or tracing where they came from), gift letters if applicable, investor agreements, the signed standby agreement for any standby seller note (SBA Form 155 or the lender's equivalent), and receipts for any due diligence costs you're counting. Large unexplained deposits into your account shortly before closing will be questioned.
Ways people build the injection
Savings, sale of other assets, family money given as a true gift, minority investors, a standby seller note, and sometimes retirement funds through a ROBS structure. Each has trade-offs; see investors, standby notes and ROBS.
Worked example: building a $150,000 injection from three sources
Illustrative example, not a recommended structure
Project cost is $1,500,000, so the minimum injection is $150,000, at least half ($75,000) from unlimited sources. You have $60,000 of savings. Your parents give you $20,000 as a documented gift with no repayment. That's $80,000 of unlimited-source money. The seller agrees to a $50,000 note on full standby, and a friend invests $20,000 for a 4% minority stake. Limited sources: $70,000, under the $75,000 cap. Total: $150,000. Then the lender reviews: the gift letter and transfer records, the seller's signed standby agreement (SBA Form 155), and the investor's subscription documents. Any piece that doesn't meet the rules gets excluded, so have a backup source in mind.
Worked example: when the price is above the valuation
Illustrative example, not a real deal
Project cost is $1,000,000 ($950,000 price plus $50,000 of closing costs and working capital). Minimum injection: $100,000, of which up to $50,000 can come from limited sources. You plan $60,000 cash and a $40,000 full standby seller note. The lender's valuation comes in at $880,000, $70,000 below the price. SOP 50 10 8.1 requires the excess of price over the valuation to be covered by equity, so your equity must rise. And any extra limited-source money used to cover a price above the valuation must be on full standby. If you agree with the seller to raise the standby note to cover part of the gap, the half-of-injection limit and the standby terms both apply. Practically: either the price comes down toward the valuation, you add cash, or the seller agrees to more fully-standby financing within the rules. Ask your lender to run the numbers before you renegotiate.
Two technical points from the 2026 update
SBA's technical update to SOP 50 10 8.1 (effective October 1, 2026) clarified that working capital adjustments in the purchase agreement (the "true-up" after closing) are not treated as seller rebates and may be treated as cash to the borrower. The SOP also allows the cost of required due diligence reports (the valuation and any QoE) to be passed to the borrower and counted toward the equity injection. Keep receipts for both. This is general information, not lending advice; your lender applies the SOP to your deal.
How a larger injection changes coverage
Illustrative example, not a real deal or rates
Project cost is $1,000,000 and earnings available for debt service are $160,000. With the 10% minimum injection, you borrow $900,000 over 10 years at 10.5% (an example rate): about $145,700 a year, and coverage is $160,000 ÷ $145,700 = 1.10, below the 1.25 minimum. With a $200,000 injection, the loan is $800,000, payments are about $129,500, and coverage is 1.24, still just short. With $300,000 in, the loan is $700,000, payments are about $113,300, and coverage is 1.41. More equity can make a deal financeable, but it also means more of your own money at risk. If the deal only works with a large injection, ask whether the price is right.
When the money needs to be in place
Lenders verify the injection before closing, and many ask for bank statements showing where the money came from over a recent period. Large deposits that appear shortly before you apply will need a paper trail: a sale of assets, a gift letter, a loan document. Move money into a single account early, and keep the records.
Keep a folder with each source's statements and letters; the lender will ask more than once.
Frequently asked questions
Is the SBA down payment 10% or 20%?
The SBA minimum for change-of-ownership loans is 10% under SOP 50 10 8.1. Individual lenders may require more, and you'll need more if the price exceeds the lender's valuation.
Can a gift count as my equity injection?
Gifts aren't separately listed in the SOP's equity categories. A gift that's truly unborrowed cash with no repayment obligation is generally treated as cash, but lenders will want gift letters and bank records. Confirm with your lender.
Can I borrow my equity injection?
Only in specific ways. Cash from a personal loan to a guarantor counts as an unlimited source if it's repaid from something other than the business's cash flow. Salary from the business doesn't qualify.
Do my due diligence costs count?
Under the SOP, funds you spend on the required financial due diligence reports (valuation, QoE) can count toward the equity injection.
How far back does a lender trace my equity?
Lenders typically want bank statements showing the funds in your accounts, often for a few months, and an explanation and documents for any large recent deposits (a gift letter, a sale of assets, a retirement rollover). Start gathering the paper trail before you apply, and avoid moving money around unnecessarily.
Can the seller lend me the down payment?
Not as a regular loan. A seller note counts toward the injection only if it's on full standby (no payments of principal or interest for the life of the SBA loan), and together with other limited sources it can supply no more than half of the required injection. The rest must come from unlimited sources such as your own cash.
