SBA Loan Down Payment to Buy a Business: Requirements and How Much Money Down
SBA loan down payment to buy a business: the 10% minimum equity injection, when a seller note counts toward it, and what changes on 1 October 2026.

Short answer: the SBA requires a minimum equity injection of 10% of total project cost when a 7(a) loan finances a change of ownership. On a $1,000,000 purchase that is $100,000, and up to half of it can come from a seller note on full standby, so $50,000 of genuine buyer cash is the realistic floor, which is why buying a business with no money down is not achievable on an SBA deal. From 1 October 2026 that 10% can no longer be reduced or waived on a first acquisition. Most lenders ask for more than the minimum anyway. Last updated August 2026.

The down payment is one line in a larger closing stack. For the whole sequence, with the time and cost of each stage, see how to buy a business.
How much of a down payment do you need for an SBA loan?
Ten percent of total project cost is the SBA floor for a business acquisition. Total project cost is not the same as the purchase price: it includes the price plus closing costs, working capital and any soft costs rolled into the deal, so the injection is calculated on a slightly larger number than the one on the purchase agreement. The SBA sets the minimum and the lender sets its own credit policy on top, which is why a bank quote of 15% or 20% is common and is not a sign that anything is wrong with your deal.
| Purchase price | Minimum 10% injection | Maximum standby seller note toward it | Buyer cash floor | Approximate 7(a) loan |
|---|---|---|---|---|
| $250,000 | $25,000 | $12,500 | $12,500 | $225,000 |
| $500,000 | $50,000 | $25,000 | $25,000 | $450,000 |
| $1,000,000 | $100,000 | $50,000 | $50,000 | $900,000 |
| $2,000,000 | $200,000 | $100,000 | $100,000 | $1,800,000 |
| $3,000,000 | $300,000 | $150,000 | $150,000 | $2,700,000 |
| $5,000,000 | $500,000 | $250,000 | $250,000 | $4,500,000 |
Those figures are our arithmetic on the published SBA minimums, using the purchase price as a stand-in for total project cost. Add closing costs and working capital and every injection number moves up. Treat the table as the shape of the requirement, not as a quote.
Where can the SBA down payment come from?
The injection has to be money that is genuinely at risk, and the lender has to be able to trace it. Cash you already hold is the cleanest source. Borrowed money generally does not count, because a loan you have to repay out of the same business cash flow is not equity, and that is the test underwriting applies to every source you name.
| Source | Counts toward the injection? | What the lender will want |
|---|---|---|
| Your own cash and marketable securities | Yes | Two to three months of statements showing the funds seasoned and not recently deposited |
| Seller note on full standby | Yes, capped | Subordination, no principal or interest for the loan term, and no more than half the required injection |
| A gift from family | Usually yes | A signed gift letter confirming no repayment obligation, plus the donor's source of funds |
| An equity partner buying in | Yes | Their own documented funds, and a guaranty from them if they take 20% or more |
| Retirement funds through a ROBS | Yes | A correctly formed C corporation and plan, because the money arrives as equity in the company rather than as a loan |
| Fees you have already paid | Yes | Receipts. Out-of-pocket diligence costs such as the valuation count toward the injection |
| A personal loan or credit line | No | Repayment out of business cash flow disqualifies it as equity |
| A seller note with normal payments | No | Only full standby debt counts. A note that amortizes is just debt |
The retirement route is the one buyers most often overlook, and it is the only source on that list that can produce six figures of injection cash without touching a savings account. A rollover as business startup moves an existing 401k or IRA balance into a plan sponsored by a new C corporation, and that plan buys the corporation's stock, so the cash lands as equity rather than as borrowed money. It is legal, it is common on small acquisitions, and it costs real money to run and to unwind, which is why it is worth reading the ROBS 401k rules and cost in full before you count it as your down payment.
Can a seller note count as the SBA down payment?
Partly, and only on strict terms. Seller debt counts as equity for SBA purposes only when it is subordinated to the 7(a) lender and placed on full standby, meaning no payments of principal or interest for the entire term of the loan. It also sits under the limited sources cap, so seller debt and other limited sources together cannot supply more than half of the required injection. Half has to be real buyer money.
That is a heavier ask than it sounds. A seller agreeing to standby on a ten-year loan is agreeing to wait a decade for that slice of the price, with no interest in the meantime. Many will not, and the ones who will usually price it into the headline number. There is one improvement under the new rulebook: seller debt structured this way becomes eligible for refinancing once it has been in place and current for 36 months, which gives a cooperative seller a visible exit rather than an open-ended wait.
Can you get an SBA loan with no money down?
Not for a business acquisition. The 10% equity injection is an SBA program requirement on a change of ownership, and from 1 October 2026 it explicitly cannot be reduced or eliminated on an Initial Acquisition, meaning a buyer who was not already an owner or an employee of the target. Offers of no-money-down SBA acquisition financing are either describing a different loan product or describing the seller-note structure above, which still needs half the injection in cash.
What changes on 1 October 2026
SBA issued SOP 50 10 8.1 on 14 August 2026, and it takes effect for every application issued an SBA loan number on or after 1 October 2026. Applications that receive a loan number through 30 September stay under the current rules. The trigger is the loan number, not your closing date, so a deal signed in September that slips into October is underwritten under the new standard.
For a buyer budgeting a down payment, three changes matter. The 10% injection becomes non-reducible on a first acquisition, so there is no lender discretion left to argue with. Every change of ownership now needs an independent business valuation from an accredited source, ordered by and prepared for the lender, which is a new cost on small deals that previously escaped it below $250,000. And the debt service coverage floor for a first-time acquisition rises from 1.15 to 1.25, which does not change the injection percentage but does shrink the loan a given cash flow will support, quietly raising the cash you need to bridge the same price.
Purchases at or above $3,000,000 also pick up a mandatory Quality of Earnings report containing a Cash Proof, which reconciles bank statement data against the income statement and the tax return across the trailing twelve months and the last two fiscal years. If you are preparing for that review, the unglamorous first step is getting the seller's raw statements into a form you can actually tie out, and being able to convert PDF bank statements into a spreadsheet turns a weekend of retyping into an afternoon of reconciling. If the QoE lands on a lower earnings figure than the seller claimed, the lender must recalculate coverage from the new number, and any shortfall against the agreed price comes out of your equity rather than the loan.
Why your lender will ask for more than 10%
The SBA minimum is a floor, not a target. Lenders routinely require 15% to 25% when the buyer has no direct industry experience, when the purchase is mostly goodwill with little collateral behind it, or when coverage is thin at the asking price. Software and online businesses hit two of those three at once: there is no equipment to lien and no building to appraise, so the loan rests on cash flow and your personal guaranty alone. A larger injection is the lever a lender pulls to get comfortable.
This is worth knowing before you make an offer, because the gap between 10% and 20% on a $1,000,000 deal is $100,000 of your own money. Ask a prospective lender early how many acquisitions of intangible-asset businesses they closed last year, and what injection they required. A vague answer from a bank that has never funded one is how deals die at month three, after you have already spent money on diligence.
What the down payment does not cover
The injection is your equity in the deal. It is not the whole cash requirement. On top of it you will pay the SBA upfront guaranty fee, charged on the guaranteed portion of the loan at 2% up to $150,000, 3% from $150,001 to $700,000, and 3.5% on the first $1,000,000 of the guaranteed portion plus 3.75% above that up to $5,000,000 in fiscal 2026. On a $900,000 loan with a 75% guaranty, that is roughly $23,625. Then add the lender's packaging fee, the independent valuation, legal review, any Quality of Earnings work, and closing costs.
The consolation is that out-of-pocket diligence costs count toward your injection rather than sitting on top of it. The lender pays SBA a separate annual service fee of 0.55% of the outstanding guaranteed balance and is expressly forbidden from passing that one to you, so if it appears on a term sheet, question it.
How to prove the money is yours
Underwriting wants seasoning and traceability. Two to three months of statements showing the funds sitting in your account is the normal standard, and a large deposit that appears the week before closing will be questioned until you document where it came from. Move money into the account you plan to fund from well ahead of time, keep the paper trail for anything sold or transferred, and get a signed gift letter early if family is contributing. None of this is difficult, but all of it is slow if you start it late, and it is one of the most common reasons a funded deal misses its closing date.
Where to go from here
If you are pricing a financed acquisition, start with the rules the lender will apply. Our guide to the SBA loan to buy a business sets out the full requirement set, the FY2026 fee bands and the coverage test, and it lays out what the 1 October rulebook change does to a deal that is already in motion. For software targets specifically, using an SBA loan to buy a SaaS business covers why lenders treat intangible collateral differently, and how to finance a SaaS acquisition compares SBA debt against seller paper and equity. Before you commit to a price, verifying the seller's MRR is the check that decides whether the earnings you are financing against survive contact with a lender's transcripts.
Buyouts lists AI SaaS with verified MRR, ARR, growth and churn, which is the same evidence a lender asks for. To be straight about the limit of that: verified marketplace metrics help you shortlist and help a lender get started, but they do not replace an independent valuation or a Quality of Earnings report, and no lender will treat them as if they do.
