What is the typical down payment for an SBA loan?

If you’re trying to figure out how much cash you need to close an SBA loan, you’ve probably heard the number 10% and assumed that’s the answer. Sometimes it is. But the real number depends on what you’re buying, which loan program you’re using, and what sources of funds the lender will accept. Plan around the wrong figure and you’ll find out at the worst possible moment that you’re short.

At Small Business Funding, we work through this question with borrowers every day. What you need to bring to the table isn’t one number. It’s a calculation that changes based on your situation, and it’s one of the first things we help buyers get right before anything else moves forward.

Down Payment vs. Equity Injection: Why the Terminology Matters

Here’s the first thing most buyers get wrong: your down payment doesn’t have to be all cash. SBA lenders don’t call it a down payment at all. They call it an equity injection. That distinction matters before you start planning around a number.

Your equity injection is the total upfront contribution you make as the borrower. It can come from cash savings, yes. But it can also come from seller financing, retirement fund rollovers, gift equity, and other sources, depending on how they’re structured and disclosed. Most buyers assume “down payment” means cash from a savings account. Many of them are planning around a number that’s higher than it needs to be.

Here’s what that means in practice. If you’re buying a business for $500,000 and the required equity injection is 10%, that’s $50,000 that must come from you in an acceptable form. Knowing what forms qualify changes how you approach the deal.

TIP: We help you identify every qualifying source of equity before you apply, so you’re not leaving options on the table or planning around a cash figure that’s higher than it needs to be.

How the Down Payment Requirement Changes by Loan Type and Use

There’s no single SBA down payment number. The requirement depends on the loan program, what you’re buying, and your business profile. Here’s how each scenario plays out.

SBA 7(a) Loans: Business Acquisitions and General Use

For most business acquisitions using a 7(a) loan, lenders require a 10% equity injection. That’s the most common benchmark, and it’s where most borrowers start their planning. But 10% is a lender standard, not an SBA rule.

Lenders set their own injection requirements within SBA guidelines. Some require more, particularly if your credit is below their threshold, the business has weak cash flow, or the industry carries higher risk. If your use of funds is primarily working capital or equipment rather than an acquisition, injection requirements vary and are sometimes lower.

The right lender matters here as much as the right number.

TIP: We know which 7(a) lenders are actively funding business acquisitions right now and what their current requirements look like. We route your file to the ones most likely to approve it at your loan size.

SBA 504 Loans: Real Estate and Equipment

The 504 program is designed for fixed assets, and it has a tiered equity injection structure based on who you are and what you’re buying:

• Established businesses acquiring standard commercial property or equipment: 10%
• Special purpose properties (gas stations, hotels, car washes, funeral homes): 15%
• Startups or businesses with less than two years of operating history: 20%

These tiers are more consistent across lenders than 7(a) requirements because the 504 program involves a Certified Development Company (CDC), a nonprofit lender that partners with a bank to fund the project.

Not every property is treated the same, and that distinction can change how much cash you need to bring to the table.

TIP: If you’re not sure whether your property qualifies as special purpose, we can confirm that before you apply. That distinction shifts your injection requirement by 5 to 10 percentage points.

Why Startups Face a Higher Bar Than Established Buyers

If you’re purchasing a new franchise or launching from scratch, expect a higher equity injection, typically in the 20 to 30% range. Lenders set this bar higher because there’s no operating history to demonstrate repayment ability. The larger injection offsets that risk.

This surprises a lot of buyers. They assume acquiring a new franchise works the same as buying an existing business with revenue. It doesn’t. A resale with two years of operating history is a fundamentally different credit profile than a greenfield startup. Knowing that now lets you plan your injection correctly rather than finding out during underwriting.

TIP: We help startup borrowers understand the injection threshold they need to hit before they apply, so the number doesn’t come as a surprise when the lender reviews the file.

What Actually Counts Toward Your Down Payment

Here’s what most buyers don’t realize until they’re already in the process: your equity injection doesn’t have to come entirely from cash savings. Several other sources qualify, and knowing them can change what deals are actually within reach.

Qualifying sources include:

• Personal cash savings: the most straightforward source and easiest to document
• Retirement fund rollover (ROBS): investing 401(k) or IRA funds into the business through a structured rollover, without triggering early withdrawal penalties or income tax
• Seller financing (standby note): when the seller agrees to carry a portion of the purchase price under specific standby terms, it can count toward your injection
• Gift equity: funds given by a family member, typically requiring a signed gift letter and documentation of the transfer

Each source has its own documentation requirements. Lenders trace every dollar and confirm its origin.

When Seller Financing Can Be Part of Your Equity Injection

A seller standby note is one of the most useful and least understood tools in SBA deal financing. If the seller agrees to carry a portion of the purchase price on full standby, meaning no payments are made for the first 24 months, lenders may count it as part of your equity injection.

What that means in practice: a buyer with 5% in cash might reach a 10% total injection if the seller carries the remaining 5% on standby terms. The note must be disclosed to the lender upfront, and the seller must agree to the payment deferral. When it works, it closes the gap between what a buyer has and what the deal requires.

Most buyers find out about this option at the worst possible moment, after they’ve already started planning around a cash number they can’t hit.

TIP: We’ve structured many deals with seller standby notes as part of the equity injection. We know which lenders are comfortable with this arrangement and how to present the documentation correctly.

Using Retirement Funds (ROBS) as Equity

A Rollover for Business Startups (ROBS) lets you invest retirement savings from a 401(k) or similar plan into a business without paying early withdrawal penalties or income tax. The funds move through a new C-corporation structure set up specifically for this purpose.

ROBS is a legitimate strategy, but the structure must satisfy IRS requirements and the lender’s documentation standards. Mistakes in execution can create tax exposure or raise concerns during underwriting. Getting it set up right from the start is not optional.

TIP: If you’re considering using retirement funds as equity, talk to us early. The ROBS structure needs to be right before anything else moves forward.

What Lenders Won’t Accept and How They Check

Not every source of funds qualifies as equity injection. Before closing, lenders review your bank statements, typically covering 3 to 12 months, and trace where your injection funds came from. What they find determines whether your injection holds up.

Common sources that create problems:

• Borrowed funds not disclosed to the lender. If you took out a personal loan or drew from a line of credit to fund your injection and didn’t tell the lender, they’ll find it when they pull your statements. Undisclosed debt is a significant red flag and can end your application.
• Large deposits without a clear paper trail. A meaningful deposit that appeared shortly before closing will prompt questions. If you can’t document the source with a gift letter, asset sale record, or documented transfer, it may not count.
• Cash drawn from the business being purchased. Equity must come from outside the business you’re buying, not from it.

The most common mistake is using borrowed money for the injection without disclosing it. Not out of deception, but because many buyers simply don’t know it’s a problem. Knowing this before you plan your injection is worth a lot.

TIP: We review your equity injection plan before you apply so we know what will hold up to lender scrutiny and what needs to be restructured before anything goes in.

What to Do If You’re Short on the Down Payment

Coming up short on equity is a common situation. It’s also one that has more options than most buyers realize when they first hit the number.

If you’ve done the math and you don’t have everything you need, here’s where to look:

• Negotiate seller participation. Ask whether the seller is willing to carry a portion of the purchase price on standby. Even a 5% seller note can close the gap between what you have and what the lender needs.
• Bring in a co-investor. A partner who contributes equity can combine their injection with yours, as long as both contributions are documented and disclosed from the start.
• Revisit the loan structure. A smaller loan or a different program may require a smaller injection. If your working capital needs can be separated from the acquisition price, you may qualify for a structure that fits what you have.
• Work with lenders that apply requirements more flexibly. Injection requirements are set by lenders, not the SBA. Some are more flexible for strong borrowers who are short on cash but solid on cash flow and credit.

If you’re close but not quite there, the answer isn’t always to wait and keep saving. It’s to find the right structure and the right lender for your situation.

TIP: If you’re not sure whether your equity qualifies or how much flexibility exists, we can walk through your injection plan directly before you apply anywhere.

Bottom Line

The typical SBA down payment is 10% for most business acquisitions. But that number isn’t fixed, and it doesn’t have to be all cash. It changes based on the loan program, what you’re buying, and whether you’re an established borrower or a startup. Seller financing, retirement fund rollovers, and gift equity can all count when they’re structured correctly and disclosed to the lender.

Many buyers rule themselves out before they understand the full picture of what qualifies. Knowing what’s actually on the table changes what deals are within reach.

If you’re planning a purchase and want to confirm whether your equity qualifies, Small Business Funding can review your situation directly. We’ll walk through the number you need, the sources that count, and the lenders most likely to work with your profile.
