An SBA 7(a) loan costs more than its advertised interest rate: borrowers also pay a one-time SBA guaranty fee, and on top of that, lenders can charge as much as 6.5 percentage points over the base rate on the smallest loans, according to the SBA's published 7(a) loan terms. The exact mix depends on loan size and maturity.
What Is an SBA 7(a) Loan, and Who Sets the Price?
The 7(a) program is the Small Business Administration's largest general-purpose loan product, and the agency caps it at $5 million per loan. The SBA doesn't hand out the cash itself — a bank or other approved lender does — and in exchange the agency guarantees a slice of the balance if the borrower defaults.
That guarantee is tiered by loan size: up to 85% on loans of $150,000 or less, and 75% on anything larger, per SBA program terms. The agency's own maximum exposure on a single loan is capped at $3.75 million, or $4.5 million for International Trade loans. To qualify at all, a borrower has to be judged creditworthy and unable to get comparable credit from a non-federal lender on reasonable terms.
How Big Is the Guaranty Fee?
Every 7(a) loan carries an upfront SBA guaranty fee, and lenders are permitted to pass that cost on to the borrower. The SBA does not fix a single number for every loan; the specific percentage schedule is republished each fiscal year through an SBA Information Notice and varies by loan amount tier. An owner shopping a 7(a) loan should ask the lender for the current fiscal-year fee schedule rather than assume last year's numbers still apply.
What's the Annual Service Fee, and Who Actually Pays It?
Separate from the upfront fee, the SBA charges lenders an ongoing annual service fee on the outstanding balance of the guaranteed portion of each loan — and the agency's terms state plainly that this one "cannot be charged to borrowers." It's a cost the lender absorbs, not a line item that shows up on a borrower's amortization schedule.
The rate has moved during the current fiscal year. For 7(a) loans approved from March 27, 2025 through September 30, 2026, the SBA set a flat annual service fee of 55 basis points — 0.55% — of the guaranteed outstanding balance. Earlier in the same fiscal cycle, from October 1, 2024 through March 26, 2025, the fee was tiered instead of flat: waived entirely on loans of $500,000 or less, set at 17 basis points on the $500,001-to-$1,000,000 band, and 55 basis points above $1 million.
How Much Interest Can a Lender Charge?
For variable-rate 7(a) loans, the SBA caps how far above its published base rate a lender can price the loan, and the ceiling shrinks as the loan gets bigger.
| Loan Amount | Maximum Rate Above SBA's Base Rate |
|---|---|
| $50,000 or less | 6.5 percentage points |
| $50,001 to $250,000 | 6.0 percentage points |
| $250,001 to $350,000 | 4.5 percentage points |
| More than $350,000 | 3.0 percentage points |
Fixed rates are capped too, pegged to the prime rate under SBA maximums that are published separately. A smaller loan carries a wider allowable spread, which is one reason the true cost of a 7(a) loan doesn't scale down evenly with the amount borrowed — the fees and the rate ceiling both work against very small loans.
How Long Do Borrowers Have to Repay?
Standard 7(a) maturities run 10 years or less, unless the loan finances or refinances real estate or equipment with a useful life longer than that — in which case the term can stretch to as long as 25 years for real estate. A longer amortization schedule lowers the monthly payment but stretches out the total interest paid, on top of whatever the guaranty and service fees already added to the loan's cost.
The Bottom Line for Owners
None of these numbers are secret, but they aren't printed together on a single rate sheet, either. A 7(a) loan's real cost is the interest rate plus an upfront guaranty fee the lender may pass through, set against a rate cap and a guarantee level that both shift with loan size. Owners comparing offers should ask each lender to itemize the guaranty fee, the interest rate against the SBA's cap for that loan size, and the maturity — because the annual service fee, at least, is one cost the borrower shouldn't be asked to cover directly.
FAQ
Does the SBA lend the money directly? No. A 7(a) loan is made by a private lender, such as a bank or credit union, and the SBA guarantees a portion of the balance — up to 85% on loans of $150,000 or less and 75% on larger loans, under the agency's published program terms.
Can a lender charge more than the SBA's rate cap? No. The SBA sets a maximum spread above its base rate for variable-rate 7(a) loans, ranging from 6.5 percentage points on loans of $50,000 or less down to 3.0 points on loans over $350,000.
Who pays the annual service fee? The lender does. The SBA's loan terms specify that this fee, charged against the guaranteed portion of the balance, "cannot be charged to borrowers" — unlike the upfront guaranty fee, which lenders may pass along.
How long can a 7(a) loan run? Most 7(a) loans mature in 10 years or less. Loans that finance real estate, or equipment with a useful life beyond 10 years, can run longer — up to 25 years for real estate.
What's the biggest 7(a) loan the SBA will guarantee? The program caps loans at $5 million. The SBA's own guaranteed exposure on a single loan is capped separately, at $3.75 million — or $4.5 million for International Trade loans.
