How Much Down Payment Does an SBA Loan Actually Need?

The short answer

It depends on what the loan is for, and the SBA's own floor is lower than most owners expect. For a business acquisition, the SBA requires an equity injection of at least 10 percent of the total project cost. For commercial real estate, 10 to 20 percent is typical, with single-purpose properties at the high end. For expansion and working capital loans to established businesses, there may be no down payment requirement at all beyond what the lender's own policy asks. "SBA loans need 20 to 30 percent down" is bank folklore, not an SBA rule.

Acquisitions: the 10 percent injection

When an SBA loan funds a change of ownership, the buyer must put real equity into the deal: at least 10 percent of everything the project costs, including the price, closing costs, and working capital built into the loan. The injection is the SBA's proof that the buyer has something at stake. Part of it can come from the seller, through a seller note, but only when that note sits on full standby, meaning the seller collects nothing until the SBA loan is well seasoned under the program's rules. Our acquisition breakdown walks through the structure.

Where the injection can come from

Your own savings are the cleanest source. A seller note on standby is the most useful one, because it cuts the cash you need at closing without weakening the file. Borrowed money is the dangerous source: if you borrow your down payment, the SBA requires that the borrowed part be repaid from income outside the business's cash flow, so the new loan's coverage math isn't secretly carrying two payments. Home equity is the common version of this, and it works when the household income carries it. What never works is hiding a borrowed injection. Underwriters find it, and a file with a hidden debt in it's worse than a file with a small injection in it.

Real estate: 10 to 20 percent, by property type

Owner-occupied real estate under the 7(a) program typically lands between 10 and 20 percent down. A general-purpose building (office, retail, warehouse that many businesses could use) sits at the low end. A single-purpose property (a car wash, a hotel, a gas station) sits at the high end, and a startup buying a single-purpose property can be asked for the most. The 504 program splits its structure differently, with the borrower's piece commonly at 10 percent, 15 for single-purpose, and the bank and SBA shares behind it.

The number that matters more than the down payment

Owners fixate on the injection and miss the test that actually decides the loan: coverage. Cash flow must cover the payment at 1.25x on historicals for an acquisition. A buyer with 20 percent down and weak coverage gets declined. A buyer with exactly 10 percent down and strong, documented coverage gets funded. Put your energy in that order: coverage first, structure second, injection third.
