SBA Loan to Buy a Business: 2026 Requirements, Down Payment, and the Price It Will Finance

An SBA loan to buy a business in 2026 will finance up to $5,000,000 with a minimum 10 percent equity injection, of which at least half must be the buyer's own cash. The rest of the answer is a coverage test: the business has to produce enough cash after the buyer takes a living wage to cover annual loan payments by at least 1.15x, and most lenders want 1.25x. Run that arithmetic on a 10-year term at current pricing and it caps an SBA-financed purchase at roughly 3.5x to 4.5x seller discretionary earnings. That ceiling, not the seller's opinion of the business, is what decides whether a deal closes.

Most guides to SBA acquisition lending stop at the eligibility checklist. The checklist is the easy part. What actually kills deals is the moment a lender models the loan against the earnings and finds the payment does not fit. This piece works through that math with real numbers, so you can price a business before you spend three months in underwriting.

What are the requirements for an SBA loan to buy a business?

The core requirements are consistent across lenders, because the SBA sets them in its Standard Operating Procedure, SOP 50 10 8, effective June 2025. A buyer needs a 10 percent equity injection on the total project cost, a credit score most lenders want at 680 or higher, relevant management experience, and a target business that has been operating and profitable. The business itself must be a for-profit US operation meeting SBA size standards, which in practice means revenue under roughly $40M and tangible net worth under $15M.

One structural point deserves emphasis because it surprises nearly everyone: the loan is amortized over 10 years when you are buying goodwill, which is what almost every service business sale is. A 10-year amortization on a seven-figure loan produces a large annual payment, and that payment is the constraint the whole deal has to survive.

How much down payment do you need for an SBA loan to buy a business?

Ten percent of the total project cost is the SBA minimum, and at least half of it has to be the buyer's own unencumbered money. Personal savings qualify, as does a retirement rollover through a ROBS structure, a documented gift from family, and home equity. Borrowed funds and credit card advances do not.

The part worth knowing is the standby seller note. A seller note placed on full standby, meaning no principal and no interest paid for the entire term of the SBA loan, can generally count toward up to half of the required injection. On a $1.2M purchase, that turns a $120,000 requirement into roughly $60,000 of buyer cash plus a $60,000 standby note. Sellers agree to this more often than buyers expect, because it is frequently the difference between the deal closing and the buyer walking. First-time buyers with no operating history in the sector should still plan for a lender to ask for 15 to 25 percent regardless of what the SBA permits.

How much can you actually borrow against a business?

This is the question the checklist never answers, and it is the one that determines your price. A lender does not lend against the purchase price. It lends against what the business earns after the buyer has been paid a living wage, discounted by a safety margin.

The calculation runs like this. Start with seller discretionary earnings. Subtract a market-rate salary for the buyer, because the buyer has to eat. Subtract a capital expenditure reserve if the business owns equipment. What remains is available for debt service. Divide that by the coverage ratio the lender requires, and you have the maximum annual loan payment. Work backwards through a 10-year amortization at current rates and you have the maximum loan, and therefore the maximum price.

Run that on a business earning $400,000 of SDE, with an $80,000 buyer salary and a 1.25x coverage requirement at a 10.5 percent rate. The available cash flow is $320,000, which supports about $256,000 of annual debt service, which supports a loan near $1.58M and a purchase price near $1.76M. That is 4.4x SDE. Add a 5 percent capital expenditure reserve and it falls to 4.1x. Have the lender stress the rate to 12.5 percent and it falls to 3.8x.

Maximum purchase price as a multiple of SDE that clears the coverage test, on a 10-year amortization at 10.5 percent with a 10 percent equity injection, assuming a buyer salary of $60,000, $80,000, and $110,000 respectively. Rates and lender overlays move these numbers, so treat them as the shape of the constraint rather than a quote.

Two things fall out of that table. Bigger businesses support higher multiples, because the buyer's salary consumes a smaller share of the earnings. And the ceiling sits meaningfully above what businesses actually sell for: the all-industry median is about 2.5x SDE, and the closed medians in our reference table of SDE multiples by industry show only a handful of sectors clearing 4x. Financing is not usually the binding constraint at typical prices. It becomes the binding constraint precisely when a seller pushes for a premium.

Can you buy a business with an SBA loan with no money down?

Not through the 7(a) program as it currently stands. The 10 percent injection is a rule, not a lender preference, and the requirement that half of it be genuine buyer cash exists specifically to stop the zero-down structures that were common before. What you can legitimately do is reduce the cash portion using a full standby seller note, use a ROBS rollover to fund the injection from a retirement account without triggering an early withdrawal penalty, or bring an equity partner who contributes cash for a minority stake.

Be careful with the advice circulating that a seller note alone can cover the whole injection. On full standby it can generally cover up to half. Anyone telling you otherwise is describing a structure that will not survive the lender's credit committee.

How long does an SBA loan to buy a business take?

Sixty to ninety days from signed letter of intent to funding is normal, and it stretches when the seller's financials are not ready. The steps that consume the time are the lender's credit approval, the independent business valuation the SBA requires on most change-of-ownership deals above a threshold, the buyer's own diligence, and the closing conditions. Deals rarely stall on the loan itself. They stall waiting for a seller to produce three years of clean financials, or waiting on a landlord.

The valuation step has its own rules about when it is required, who is qualified to perform it, and what happens if the number comes in under the agreed price. Those are worked through in detail in our guide to business valuation for an SBA loan.

The lease requirement that quietly kills deals

Here is a condition that appears nowhere in most buyer checklists and sinks a meaningful share of otherwise financeable transactions. If the business operates from leased premises, the SBA generally expects the remaining lease term, including renewal options the tenant controls, to be at least as long as the loan term. On a 10-year loan, that means roughly 10 years of secured occupancy.

A restaurant with four years left on its lease and no options is not financeable at a 10-year term, no matter how strong its cash flow is. The fix is to negotiate a lease extension with the landlord before closing, which is far easier to do while the seller still holds the relationship. Read the lease early rather than at closing: the renewal options, assignment clause, personal guarantee, and any relocation or demolition clause all matter to a lender, and pulling those terms out of a long commercial lease is exactly the sort of thing worth doing with software that abstracts the key terms from the document rather than by skimming it the week of closing.

What happens to the deal if the appraisal comes in low?

The SBA will not guarantee a loan above the appraised value of what is being purchased. If you agreed to $1.4M and the valuation comes back at $1.25M, the lender finances against $1.25M. That leaves three real options: the seller reduces the price, the buyer covers the $150,000 gap in additional cash, or the parties bridge it with a seller note on full standby. The third is the most common because it costs neither side cash at closing.

This is the strongest argument for pricing the deal realistically before the letter of intent rather than after. Both sides can sanity-check the number against sector benchmarks and against the earnings, and a gap discovered in week two is a negotiation while the same gap discovered in week ten is a crisis.

What sellers should take from all of this

If you are selling rather than buying, the financing math is your pricing constraint whether you engage with it or not. Roughly half of US small business sales involve SBA debt, so for most sellers the realistic buyer pool is people bound by the table above. Three consequences follow.

Price inside the ceiling if you want a broad buyer pool. Asking 5x SDE on a $300,000-earnings business does not just make buyers negotiate harder, it makes the deal unfinanceable for the individuals most likely to buy it, and you will spend months discovering that. Expect to carry a note, since seller financing appears in a large share of these transactions and refusing outright narrows the field considerably. And understand that the fastest way to raise your ceiling is to raise your earnings, because every scenario in the table scales with SDE while the buyer's salary does not. The levers for that are covered in increasing business value before selling, and the earnings figure itself is worth computing carefully using how to calculate SDE before you anchor on any multiple.

The short version

An SBA 7(a) loan finances up to $5M of a business purchase with 10 percent down, half of which must be buyer cash, over a 10-year term for goodwill at prime plus roughly 2 to 2.75 points. The binding constraint is the coverage test, which caps the purchase at roughly 3.5x to 4.5x SDE under normal underwriting and closer to 3x under conservative assumptions. Since most US small businesses close near 2.5x SDE, financing usually works at market prices and breaks at premium ones. Check the lease term early, price against sector benchmarks before the letter of intent, and treat a standby seller note as a normal tool rather than a concession.

To see what your own numbers imply before you approach a lender, run them through the business valuation calculator, which applies an SDE or EBITDA multiple, a revenue multiple, and a discounted cash flow and returns a range with the drivers that moved it. It is an educational estimate rather than a certified appraisal, but it is the right sanity check to run before a letter of intent.
