SBA Loan Down Payment: How Much You Actually Need
How much you put down on an SBA loan depends entirely on what the money is for. A working-capital loan, a refinance, or a line of credit often needs nothing down. A business acquisition needs a 10% equity injection, though a seller note on full standby can cover up to half of it, dropping your own cash to about 5%. Real estate on the 504 program runs 10% to 20% by property type. There is no single SBA down payment number.
Bottom line
There is no single SBA down payment. Working capital, a refinance, or a line of credit often funds with nothing down. A business acquisition needs a 10% equity injection, and a seller note on full standby can cover up to half, so your own cash can be about 5% on a $1 million deal. SBA 504 real estate runs 10% for an established general-purpose building, 15% for a new business or special-purpose property, and 20% when it is both. Budget for your use of proceeds, not the best-case headline.
"What is the SBA down payment?" is the wrong question
There is no flat SBA down payment, and looking for one sends most owners down the wrong path. The number is set by your use of proceeds: what the money buys decides what you put in. Borrow against a business you already run and the answer is often nothing. Buy a business or a building and it climbs to 10%, 15%, or 20%. The two SBA programs also handle it differently, so the first thing to settle is which one you are in, laid out in the SBA 7(a) versus 504 breakdown.
The rules below come from the SBA's own program pages for 7(a) loans and 504 loans, with the exact figures set by the SBA's Standard Operating Procedure (SOP 50 10), which is updated periodically. As of 2026, the four cases below cover almost every SBA borrower.
What the SBA requires, by use of proceeds
The down payment on an SBA loan tracks one thing above all: whether you are borrowing against a business that exists or buying something new. Four cases cover nearly everyone. The first needs no money down. The other three set the equity you have to bring, and the amount climbs with the size of the asset and the risk of the deal.
Working capital, a refinance, or a line: usually nothing down
For working capital, a business debt refinance, or a line of credit, a 7(a) loan usually asks for no down payment at all. You are borrowing against a business that already exists, not buying a new asset, so there is nothing to put equity toward. This is the case most owners are actually in, and it is why 'as low as $0 down' is a fair line for a working-capital 7(a), even though it stops being true the moment you buy a business or a building.
Buying a business: a 10% equity injection
When SBA money buys a business, a full change of ownership, the current rulebook requires a minimum equity injection of 10% of total project cost. What matters is what counts toward that 10%. A seller note on full standby, meaning the seller takes no principal or interest for at least the first two years, can cover up to half of it. On a $1 million purchase, that turns $100,000 of required equity into as little as $50,000 of your own cash.
Commercial real estate on a 7(a): about 10% to 15%
Buying owner-occupied real estate with a 7(a) loan does not lock to a fixed structure the way a 504 does, but lenders still want equity in the deal, commonly 10% to 15% down by property and profile. A 7(a) can fold soft costs and a little working capital into the same loan, which a 504 cannot. If the purchase is mostly real estate, price the 504 first, because its down payment math and its long fixed rate often win.
Owner-occupied real estate on a 504: 10%, 15%, or 20%
The 504 has the clearest down payment rules of any SBA loan, because the structure is fixed. A bank funds about 50% in a first lien, an SBA-backed debenture funds the next slice, and you put 10% down on an established business buying a general-purpose building. That rises to 15% if the business is new, under two years old, or the property is special-purpose, such as a hotel, gas station, or car wash, and to 20% when it is both.
The acquisition case is where most of the money and most of the confusion live. Buying a business is underwritten against its cash flow and goodwill, not its hard assets, which is why the SBA sits behind the deal and an ordinary bank passes. The full walkthrough, including the coverage test that sizes the price you can pay, is in the guide to financing a business purchase, and the acquisition loan versus SBA 7(a) comparison lines the SBA route up against conventional acquisition debt. A partner buyout runs on the same 10% and standby-note math, covered in the partner buyout financing guide.
Two deals, in real dollars
Two numbers decide almost every SBA down payment question: what the money buys, and whether a seller will carry part of the deal. Run both through a purchase and the abstract percentages turn into cash you either have or you do not. Here are the two cases that come up most, on round figures you can re-run with your own.
Buying a $1,000,000 business (7(a))
~$50,000 of your own cash
Total project cost is $1,000,000. The SBA requires a 10% equity injection, which is $100,000. Negotiate a $50,000 seller note on full standby and it counts toward half of that injection, leaving $50,000 of your own cash to bring, with the 7(a) loan funding the remaining $900,000. A conventional acquisition loan on the same business would typically want 20% to 30% down, or $200,000 to $300,000. The seller note, not the interest rate, is what moves your cash to close.
Buying a $1,500,000 building (504)
$150,000 to $300,000 down
A bank writes a first mortgage near 50%, roughly $750,000, and an SBA-backed debenture covers the next layer. Your down payment is 10%, or $150,000, if the business is established and the building is general-purpose. Make it a startup or a special-purpose property such as a hotel or gas station and it steps to 15%, or $225,000. If it is both, budget 20%, or $300,000. A conventional commercial mortgage on the same building usually starts at 20% to 25% down and runs a much shorter fixed-rate period, which is why many buyers compare the 504 against a conventional mortgage before they choose.
The test: the equity injection is a floor, not a target. On top of it sit the SBA guaranty fee, closing costs, and the working capital the business needs on day one. Bring the down payment and a reserve behind it, not the down payment alone. These are illustrative figures on round numbers. Run yours against a real quote.
SBA down payment by scenario
The same borrower can face five very different down payments depending on what the SBA money is for. The table lines them up against the cash you actually bring and against the conventional alternative, so you can see where the SBA route saves the most on money down.
| Use of proceeds | Down / injection | Your own cash | Sample deal | vs. conventional |
|---|---|---|---|---|
| Working capital, refinance, or a line (7(a)) | Usually $0 | $0 of your own | A $250,000 working-capital loan can fund with nothing down. | A bank line often asks for similar or stricter terms. |
| Buying a business (7(a)) | 10% equity injection | As little as 5% with a standby seller note | $1M deal: $50,000 to $100,000, depending on the seller note. | Conventional acquisition debt wants 20% to 30% down. |
| Commercial real estate (7(a)) | About 10% to 15% | 10% to 15% | $800K building: roughly $80,000 to $120,000 down. | A conventional commercial mortgage starts near 20% to 25%. |
| 504 real estate, established, general-purpose | 10% | 10% | $1.5M building: $150,000 down, over a long fixed-rate term. | A conventional mortgage runs 20% to 25% down. |
| 504 real estate, new business or special-purpose | 15%, or 20% if both | 15% to 20% | $1.5M hotel or gas station: $225,000 to $300,000 down. | Special-purpose conventional deals can want 25% to 35%. |
Read it this way: if the money is working capital or a refinance, the SBA down payment conversation is usually over before it starts. If you are buying, the lever that moves your cash is the seller note on an acquisition and the property type on a 504. Both of those, not the interest rate, decide what you write a check for at closing.
The down payment is a sourcing test, not just a cash test
Having the down payment is only half of it. The SBA and its lenders have to see where the money came from, and that sourcing test stops more deals at the last minute than the amount ever does. Every dollar of your equity injection has to be traced, and usually seasoned in your account for about 60 days before closing.
A large deposit two weeks before you close is a problem, not a solution. A $40,000 wire from a relative, a sudden pull from a personal line, or cash you cannot document will freeze the file until you paper the trail. Equity can come from your own seasoned savings, the documented sale of an asset you can prove you owned, a compliant retirement rollover, or a gift with a signed letter that many lenders accept. What it generally cannot be is another loan the SBA loan itself is repaying, or an unsecured personal loan with no independent way to service it.
One line worth holding to: if a lender quotes a real business acquisition at zero down, slow down and read the fine print. Since the SBA rulebook reaffirmed the 10% equity injection on a change of ownership, no legitimate 7(a) lender funds a purchase with nothing down. A zero-down quote is either about working capital rather than an acquisition, or it is leaning on a seller note that has to sit on full standby to count. Before you take it, run the file the way an underwriter will, using what SBA lenders actually check to pressure-test the numbers.
The down payment mistakes that cost SBA borrowers deals
None of these is the interest rate.
The SBA loan itself is not the hard part. The damage comes from four assumptions that feel reasonable until the file is in underwriting and the cash-to-close number stops matching what you planned. Read them before you sign a purchase agreement, because each one is far cheaper to avoid than to fix at the closing table.
Assuming SBA means little or no money down
The 'as low as $0 down' line is true for working capital and refinances. It is not true for buying a business or a building. Since the SBA rulebook reaffirmed the 10% equity injection on a change of ownership, no legitimate lender funds an acquisition with nothing down. Budget the real cash your use of proceeds requires, and you will not lose a deal at the closing table over a number you could have planned for months earlier.
Draining your reserve into the equity injection
The equity injection is a floor, not the whole cost. On top of it sit the SBA guaranty fee, closing costs, and the working capital the business needs from day one. Owners who empty every account to hit the 10% land on the first day of ownership with the keys and no cash to run the place. Bring the down payment and a reserve behind it, not the down payment alone.
An equity injection you cannot source
Having the money is only half of it. Lenders trace every dollar of your injection and usually want it seasoned in your account for about 60 days. A $40,000 deposit two weeks before closing freezes the file until you paper the trail. Cash you cannot document, a sudden transfer, or an undisclosed loan will stall an approval that was otherwise clean. Line the money up early and keep the statements that prove where it came from.
Confusing the 7(a) and 504 rules, and the special-purpose jump
A 7(a) and a 504 do not share a down payment formula, and buyers who assume they do get surprised. The one that catches people most is special purpose: a hotel, gas station, car wash, or self-storage facility on a 504 steps the down payment from 10% to 15%, and a startup buying one lands at 20%. Know which program and which property type you are in before you assume the 10%.
The through-line is simple: plan the down payment as early as you plan the purchase. Know your use of proceeds, know your program, know where your equity is coming from, and season it. Do that and the down payment becomes a line item you funded on schedule instead of the surprise that kills the deal in week eight. The SBA loan itself is the lowest-cost business financing most owners will ever qualify for, which is exactly why it is worth getting the equity right.

Frequently asked questions
How much is the down payment on an SBA loan?
It depends on what the money is for. A working-capital loan, a refinance, or a line of credit often needs nothing down. A business acquisition requires a 10% equity injection, and a seller note on full standby can cover up to half of it. Owner-occupied real estate under the 504 program runs 10% to 20% by property type. There is no single SBA down payment number.
Do all SBA loans require a down payment?
No. A 7(a) loan for working capital, a debt refinance, or a line of credit commonly funds with no down payment, because you are borrowing against a business that already exists rather than buying a new asset. The down payment shows up when SBA money buys something: a business, owner-occupied real estate, or major equipment. That is where the equity injection rules apply.
Can the seller cover my SBA down payment?
Partly. On a business acquisition, a seller note on full standby can count toward up to half of the required 10% equity injection, which drops your own cash to about 5% of the price. Full standby means the seller takes no principal or interest for at least the first two years. The rest of the injection has to be your own sourced funds. The mechanics are in the guide to financing a business purchase.
What is an equity injection, and how is it different from a down payment?
Equity injection is the SBA's term, and it is broader than a cash down payment. It is the borrower's own stake in the deal, and it can include cash, the documented sale of an asset, and, on an acquisition, a seller note on full standby for up to half of the requirement. Whatever the source, it has to be verifiable and usually seasoned in your account for about 60 days before closing.
How much do you put down on an SBA 504 loan?
A 504 puts 10% down for an established business buying a general-purpose building. It rises to 15% if the business is new, under two years old, or the property is special-purpose, such as a hotel, gas station, or car wash, and to 20% when it is both new and special-purpose. A bank funds about 50% in a first lien and an SBA-backed debenture covers the rest.
Can I borrow the money for an SBA down payment?
Generally the equity injection has to be your own funds or a standby seller note, not another loan the SBA loan itself is repaying. Some sourced money can qualify: the documented sale of an asset, a compliant retirement rollover, or a gift with a signed letter that many lenders accept. An unsecured personal loan with no independent way to service it usually cannot count as equity.
Buying a business rather than borrowing against one you already run? The guide to financing a business purchase runs the 10% equity injection, the standby seller note, and the coverage test in full.
