Short answer

The SBA calls a down payment an equity injection. Start-ups and business buyers using a 7(a) loan must put in at least 10% of the total project cost. A 504 loan needs 10%, rising to 15% for a new business or special-purpose property and 20% when both apply. For other 7(a) loans, the lender sets the amount.

What is an SBA loan down payment?

Definition
Equity injection: the cash or other qualifying value a borrower puts into a project financed with an SBA loan. It’s the SBA’s term for a down payment, and on 504 loans it’s often called the borrower contribution.

Equity matters to lenders because it shows you have your own money at risk, and it gives the loan a cushion if the project costs more or earns less than planned.

Two things make SBA down payments different from a mortgage down payment:

  • It’s usually measured against the total project cost, not just the loan. If a business purchase includes working capital and closing costs, those count toward the project, so they raise the equity needed too.
  • The SBA sets the minimum only in certain situations. For start-ups, business purchases and every 504 project, the SBA’s rules, SOP 50 10 8.1, set a floor. Otherwise, the lender decides.

Lenders can always ask for more than the SBA minimum. Where the SBA sets one, a lender can accept less only in the cases the rules allow, shown in the table below.

How much down payment does each SBA loan require?

The minimum depends on the program, how long you’ve been in business and what you’re financing:

Your situation Program SBA minimum
Start-up (generating revenue for 1 year or less) 7(a) 10% of total project cost
Buying a business you don’t already own 7(a) 10%, which can’t be reduced. A seller note on full standby can cover up to half.
Buying out a partner, or your business buying another business 7(a) 10%; the lender may reduce it when your business is strong
Working capital, equipment, refinancing or real estate for an established business 7(a) No SBA minimum; set by the lender
Established business buying general-purpose property or equipment 504 10%
New business (operating 2 years or less) or special-purpose property 504 15%
New business buying special-purpose property 504 20%

A special-purpose property is a building designed for one kind of business, such as a hotel or a gas station, which is harder for a lender to resell.

Can a seller note cover part of the down payment?

Yes, for business purchases, within limits. A seller note counts toward your equity only if it is on full standby: the seller receives no principal or interest payments for the entire term of the SBA loan. Standby seller notes, other standby debt and minority investors’ equity together can cover no more than half of the required injection. The rest has to come from you.

A seller note that is paid during the SBA loan is still allowed, but it doesn’t count as equity. The lender counts its payments as debt when it checks your cash flow. Our guide to buying a business with an SBA loan walks through seller financing in more detail.

Where can your down payment come from?

Lenders verify your equity before the loan funds, so plan to show where the money came from:

  • Cash savings. Money in your personal or business accounts is the simplest source. Expect the lender to ask for bank statements and to explain any large recent deposits.
  • Documented money already spent on the project. Deposits, build-out costs or equipment you’ve already paid for may count if you can document them. Ask your lender before you assume they will.
  • A seller note on full standby, for business purchases only, up to the limit above.
  • Land or assets you already own. On some projects, especially 504 loans, property you already own can count toward your contribution. Ask the CDC or lender how it will be valued.

Other sources, such as gifts, retirement-account rollovers, home equity loans or outside investors, come with conditions or may not count at all. Ask your lender how it treats each one before you build your plan around it.

Talk to your lender before you move money between accounts or borrow against personal assets for the injection. Funds that appear suddenly can mean extra paperwork to prove where they came from.

How can you lower the cash you need at closing?

You can’t go below the SBA minimum where one applies, but you can often keep your total cash requirement down:

  1. Finance eligible fees and closing costs. The SBA guaranty fee and many closing costs can usually be included in the loan instead of paid in cash. See SBA loan fees.
  2. Use a standby seller note for part of the injection when buying a business.
  3. Consider a 504 loan for real estate. An established business buying general-purpose property puts in 10%, and lenders may ask for more on a large 7(a) real estate loan. Compare the two in our 7(a) vs 504 guide.
  4. Trim the project. Because the minimum is a percentage of total project cost, every dollar you take out of the budget lowers the equity you need.
  5. Check whether the lender will reduce the minimum on a partner buyout or an expansion purchase, when your business has strong cash flow.

Be cautious of any offer that promises a zero-down SBA loan for a start-up or a first-time business purchase. The SBA’s minimum equity injection applies to both, and seller financing can cover only part of it on a purchase.

Why might a lender ask for more than the SBA minimum?

The SBA minimum is a floor. A lender may ask for more when it sees more risk, for example:

  • Cash flow that only just covers the new payments
  • Limited experience in the industry you’re entering
  • A special-purpose property or collateral that would be hard to sell
  • A thin or damaged credit history
  • A purchase price that’s high compared with the business’s earnings

Different lenders draw these lines in different places. Before you apply, run your numbers through our borrowing estimator to see what your cash flow can support.

How do you find the right lender for your SBA loan?

Down payment expectations vary from lender to lender, especially on start-ups and business purchases. Lenders that regularly fund deals like yours tend to know which equity sources they’ll accept and how they’ll treat a seller note.

SBA Loan Connect ranks lenders using the SBA’s public 7(a) and 504 loan records, so you can see which lenders actually fund businesses like yours. Partner lenders are labeled, and getting matched is free with no credit check. See how we rank lenders or get matched with lenders.

Frequently asked questions

Can I get an SBA loan with no money down?

Sometimes. The SBA sets no minimum down payment for 7(a) loans used by established businesses for working capital, equipment or refinancing, so the lender decides. Start-ups and business purchases need at least 10%, and every 504 project needs a borrower contribution of at least 10%.

Can a seller note count toward my down payment?

Yes, when you're buying a business and the note is on full standby, meaning the seller gets no principal or interest payments for the entire term of the SBA loan. Standby seller notes can cover up to half of the required equity injection. See buying a business with an SBA loan.

Is the down payment a percentage of the loan or the project?

Generally the total project cost. The SBA minimums for 7(a) start-ups and acquisitions and for 504 projects are a percentage of everything the project costs, which can include working capital and closing costs, not just the loan amount. Ask your lender for a sources-and-uses summary that shows the math.

Does the down payment have to be my own money?

Usually most of it. Cash savings are the simplest source, and the lender will verify where the money came from. For business purchases, a seller note on full standby can cover part of it. Gifts, retirement-account rollovers and borrowed money come with conditions, so ask your lender before you count on them.

Do I need a down payment to refinance with an SBA loan?

Usually not. Refinancing doesn't add new project cost, so there is typically no equity injection, but the new loan must still meet the SBA's refinancing rules. See SBA debt refinancing.

How do I know how much I can borrow with the cash I have?

Your down payment is only part of the picture. Lenders size SBA loans mainly on cash flow. Our borrowing estimator estimates the largest loan your business's cash flow and existing debt can support.
