The SBA guarantee: how it works, who can lend and what it covers
Short answer
The SBA guarantee is a promise to the lender, not to you: if you default, SBA will buy the guaranteed share of the loan, provided the lender followed SBA's rules. It covers 85% of 7(a) loans of $150,000 or less, 75% of larger loans and 50% of SBA Express loans, up to $3.75 million of SBA exposure per business. You still owe the whole loan and still sign a personal guaranty if you own 20% or more.
"SBA-guaranteed loan" is one of the most misread phrases in small business finance. It sounds like a safety net for the borrower. It's a safety net for the lender, and it's the reason banks will lend against goodwill when you buy a business.
How the guaranty works
The lender makes the loan and services it. If it defaults, the lender works out or liquidates the collateral, and can ask SBA to purchase the guaranteed portion. SBA reviews whether the lender followed the program rules when it made and serviced the loan. If it didn't, SBA can reduce or deny the guaranty. That is why lenders treat the SOP as binding even on details that look like paperwork.
Guaranty percentages and limits
| Loan type | Guaranty |
|---|---|
| Standard 7(a) and 7(a) Small, $150,000 or less | 85% |
| Standard 7(a) and 7(a) Small, over $150,000 | 75% |
| SBA Express | 50% |
| Maximum SBA guaranty outstanding to one business and its affiliates | $3,750,000 |
A $5,000,000 Standard 7(a) loan at 75% produces a $3,750,000 guaranty, which is exactly the cap. If your business or its affiliates already have SBA loans outstanding, their guaranteed balances count against the same $3.75 million. Multiple 7(a) loans approved within 90 days of each other are combined to set the percentage. See 7(a) loan limits.
What it costs
The lender pays SBA an upfront guaranty fee when the loan is approved and an annual service fee while it's outstanding. The upfront fee is calculated on the guaranteed portion, not the whole loan, and lenders are allowed to pass it on to the borrower. Maximums under 13 CFR 120.220:
| Loan size | Maximum fee | Example |
|---|---|---|
| $150,000 or less | 2% of guaranteed portion | $100,000 at 85%: $1,700 |
| $150,001 to $700,000 | 3% of guaranteed portion | $500,000 at 75%: $11,250 |
| $700,001 to $5,000,000 | 3.5% up to $1M guaranteed + 3.75% above | $2,500,000 at 75%: $67,813 |
SBA can announce temporary changes to fees for a fiscal year through an information notice, so check what applies to your loan date. SBA Express loans to veteran-owned businesses have the upfront fee waived. Short-term loans (12 months or less) have a separate, lower fee.
What the guaranty doesn't do
- It doesn't replace your guaranty. Anyone owning 20% or more gives an unlimited personal guaranty. See SBA personal guarantees.
- It doesn't replace collateral. SBA doesn't let its guaranty substitute for available collateral; lenders must take what's there.
- It doesn't make approval easier on a weak deal. The lender still keeps 25% of the risk on most loans, and still has to meet SBA's credit standards.
- It doesn't protect you in a default. After SBA pays the lender, you still owe the debt, and SBA or the lender can pursue you and other guarantors.
Why it matters for buyers
Most of the price of a small business is goodwill, which a lender can't easily sell if things go wrong. The guaranty is what lets lenders finance that goodwill over 10 years with 10% down. It's also why SBA attaches so many conditions to acquisition loans: valuation, QoE, coverage, seller exit and the rest. They protect SBA's share of the risk.
Becoming an SBA lender
SBA's lender page lists four requirements to participate in 7(a): a continuing ability to evaluate, process, close, disburse, service and liquidate small business loans; being open to the public to make loans (not a financing subsidiary for an affiliate); continuing good character and reputation meeting 13 CFR 120.140; and supervision by a state or federal regulator satisfactory to SBA, or applying as a Small Business Lending Company or Non-Federally Regulated Lender under SOP 50 56. Delegated authority such as PLP comes later.
For banks and credit unions, the 7(a) program opens up acquisition lending that conventional policy usually can't support: goodwill-heavy deals with 10% down over 10 years. Here's the path in.
Requirements (from SBA's lender page)
- Continuing ability to evaluate, process, close, disburse, service and liquidate small business loans.
- Open to the public for loans; not a financing subsidiary primarily financing an affiliate.
- Continuing good character and reputation; ethical requirements in 13 CFR 120.140.
- Supervised and examined by a regulator satisfactory to SBA, or application as an SBLC or Non-Federally Regulated Lender under SOP 50 56.
Building an acquisition desk
- Adopt an Appendix 15 checklist and credit memo template from day one. See our checklist.
- Line up independent Qualified Source valuation providers and QoE providers, with written conflict policies.
- Set up IVES or Form 8821 transcript workflows.
- Decide policy on in-house valuations at $350,000 or less.
- Train on equity sourcing, seller note standby, and the citizenship rule.
OKtoLend is building lender-ordered valuations and QoE reports for exactly this workflow; see how it works.
Lender service providers
A Lender Service Provider (LSP) is an Agent who carries out lender functions (originating, disbursing, servicing or liquidating SBA loans) for compensation from the lender. SBA reviews the written LSP agreement, so Form 159 isn't required for those services, but fees the lender pays an LSP can't be passed on to the applicant. The lender must keep its own continuing ability to evaluate, process, close, service and liquidate loans.
Many lenders, especially smaller or newer SBA participants, use LSPs to underwrite, close or service. The rules are about keeping the lender accountable and the borrower's costs transparent.
| Question | Rule |
|---|---|
| Who pays the LSP? | The lender; fees can't be passed to the applicant |
| Form 159? | Not for LSP services under the SBA-reviewed agreement |
| Transcripts | If an LSP is used, both lender and LSP are designees on Form 8821 |
| Lender responsibility | Continuing ability to evaluate, process, close, service, liquidate |
| Other services to the borrower | Disclosed separately as an Agent on Form 159 |
For acquisitions, keep the valuation and QoE providers independent of whoever is producing the loan, including an LSP, to protect the Qualified Source independence requirement. See independent valuations.
What the guaranty means for the lender's file
The guaranty only pays if the lender followed the rules. When a guaranteed loan defaults and the lender asks SBA to purchase the guaranty, SBA reviews whether the loan was originated, closed and serviced in line with its requirements, and it can deny or reduce the payment for material deficiencies. On acquisition loans, the items SBA looks at most closely are the ones this site keeps returning to: a valuation by a Qualified Source prepared for the lender, IRS transcript verification of the seller's figures, equity from allowed sources, debt service coverage calculated correctly, and a QoE where required. A lender that treats those as paperwork, not credit work, is buying a guaranty it may not be able to collect.
Common questions
Does the SBA guarantee mean I'm guaranteed approval?
No. Guaranteed refers to SBA's guaranty to the lender if the loan defaults. Lenders still decide whether to approve, and many applications are declined.
If I default, does SBA pay off my loan?
SBA pays the lender its guaranteed share after the lender liquidates collateral. You still owe the debt, and SBA or the lender can pursue you and other guarantors.
How much does the SBA guarantee cost?
The lender pays an upfront fee on the guaranteed portion (up to 3.5% of the first $1 million guaranteed and 3.75% above that on loans over $700,000) and an annual service fee. The upfront fee is usually passed to the borrower and can be financed.
Can a new SBA lender make acquisition loans right away?
Yes, under non-delegated processing, where SBA reviews and decides. Changes of ownership follow Appendix 15 in full, which is a meaningful operational build.
Can a lender outsource SBA work?
A lender can contract with a Lender Service Provider to carry out functions under an agreement SBA reviews, but must keep its own continuing ability to evaluate, process, close, service and liquidate loans.
