The short answer by situation
| Your situation | Typical injection | Notes |
|---|---|---|
| Startup (under 2 years, no revenues) | About 10% | Sometimes more without compensating strengths like deep industry experience or strong collateral. |
| Startup with strong profile | About 10%, occasionally less | Deep experience plus hard collateral can shave a point or two at some lenders. |
| Business acquisition | About 10% | Seller notes may count toward part of it when properly structured and on standby. |
| Established, strong cash flow | 0–10% | Full financing of the project is possible at many lenders when coverage is comfortable. |
| 504 real estate purchase | About 10% | New businesses and special-purpose properties can push the borrower share toward 15%. |
Why lenders want skin in the game
The equity injection is not a toll. It is the underwriter’s evidence that you have something at stake and that your projection of the project’s cost is grounded in money you have actually counted. A borrower who has saved, raised or committed 10% behaves differently for the following five years than one who risked nothing, and lenders know it.
It also changes the loan arithmetic in your favor. A larger injection means a smaller note, a lower payment, and better coverage. The cost calculator will show you the payment difference between 10% and 20% down on your specific numbers; it is often the difference between a 1.1x and a 1.3x coverage ratio.
What counts as a down payment
- Cash savings. The simplest case: documented funds seasoned in an account, evidenced by statements.
- Gifted funds. Generally allowed with a signed gift letter from the giver stating no repayment is expected or permitted.
- Home equity. A home equity line can fund an injection at many lenders, subject to their policy on sources and debt load.
- Retained earnings. Profits left in the business, shown on the balance sheet, count when the financials are clean.
- Seller financing on an acquisition. A seller note can count toward equity when it sits on standby (no payments to the seller) for a defined period and is subordinated. The mechanics are technical; your lender will spell them out.
- Invested equipment or real estate. Contributing assets you already own toward the project can count at their documented value.
What usually does not count
Money that is itself borrowed almost never counts as an injection unless it is structured properly, such as a loan secured by an asset you own, outside the business, with terms the lender accepts. Borrowing on a business credit card or from another lender to manufacture a down payment will surface in underwriting, because the lender sees the debts on your personal financial statement. The honest version of a weak injection is a smaller project or a different program, not a concealed loan.
A worked project
That injection did not come from one place, which is normal. What mattered was that every dollar had a paper trail a lender could verify in an afternoon.
If you cannot get to 10%
Three honest paths exist. Shrink the project so that 10% of it is reachable. Add a partner or investor whose capital counts as injection. Or look at the SBA microloan program, which finances smaller amounts (typically up to $50,000) through mission-driven intermediaries with lighter equity expectations. What does not work is asking a lender to ignore the gap; the guarantee does not waive the injection.
Questions people ask next
How much of a down payment do you need for an SBA loan?
A common expectation is about 10% of the project cost for startups and business acquisitions, and less, sometimes zero, for established businesses with strong cash flow. On 504 real estate deals the borrower share is also typically around 10%, and can run to 15% for new businesses. The exact figure is lender policy, not a fixed program rule.
Can I borrow my SBA down payment?
Generally no, unless the borrowed funds are properly structured: for example, secured by an asset you own personally, outside the business, on terms your lender accepts. Money borrowed on cards or from family loans that expect repayment will conflict with your personal financial statement and usually cannot serve as equity. Gifted funds are different and are allowed with a signed gift letter.
Can gifted funds be used for an SBA loan down payment?
Yes, at most lenders, with a signed gift letter stating that no repayment is expected or permitted. The lender will still want to see the funds move through documented accounts.
Does a seller note count toward the down payment on a business acquisition?
It can. When a seller finances part of the purchase and the note is on standby (no payments for a defined period) and properly subordinated, many lenders count it toward part of the buyer’s equity injection. The standby terms are technical, so confirm the structure with your lender before you sign the purchase agreement.
