SBA 7(a) loan interest rates in 2026 aren't set by the SBA. Your lender negotiates the rate with you, and the SBA caps it with a simple formula: a base rate, usually the prime rate, plus a maximum spread that gets smaller as the loan gets bigger. Once you know the formula and current prime, you can check any quote in about a minute.
How SBA 7(a) loan interest rates are capped
SBA's lender guidance says 7(a) interest rates are negotiated between borrower and lender but are subject to SBA maximums, which are pegged to the prime rate or an optional peg rate, and that rates may be fixed or variable (SBA 7(a) terms, conditions and eligibility, checked October 2, 2026).
The binding rule for variable rates sits in 13 CFR 120.214 (eCFR, checked October 2, 2026). Three parts of it matter when you're reading a quote:
- The base rate is either the prime rate or the Optional Peg Rate. SBA can also allow alternative base rates that are widely used in small business lending, and it publishes notice of those in the Federal Register.
- The prime rate that counts is the one in effect on the first business day of the month, as printed in a national financial newspaper published each business day.
- The timing: the loan's initial maximum rate is set as of the date SBA receives the loan application.
The spread caps by loan size come straight from the regulation:
| Loan amount | Maximum variable rate |
|---|---|
| $50,000 or less | Base rate + 6.5 percentage points |
| More than $50,000 up to $250,000 | Base rate + 6.0 points |
| More than $250,000 up to $350,000 | Base rate + 4.5 points |
| More than $350,000 | Base rate + 3.0 points |
The same spreads apply to the 7(a) Working Capital Pilot lines of credit. One exception is worth knowing: SBA's lender page says Export Working Capital loans have no SBA maximum interest rate limit.
What the maximum rates are at today's prime
On the Federal Reserve's H.15 release dated October 1, 2026, the bank prime loan rate was 7.00% every day from September 24 through September 30, 2026. The Fed describes this as the rate posted by a majority of the top 25 insured U.S.-chartered commercial banks. On September 16, 2026 the FOMC raised the federal funds target range by a quarter point to 3.75%–4.00%, and the primary credit rate rose to 4.0% effective September 17 (implementation note). The 7.00% prime above reflects that hike. Prime can move again, so treat the table below as a snapshot.
| Loan amount | Spread cap | Max variable rate at 7.00% prime |
|---|---|---|
| $50,000 or less | 6.5 | 13.50% |
| $50,001 to $250,000 | 6.0 | 13.00% |
| $250,001 to $350,000 | 4.5 | 11.50% |
| Over $350,000 | 3.0 | 10.00% |
The tier edges create some odd results. A $350,000 loan can legally be priced at 11.50%, while a $350,001 loan tops out at 10.00%. If you're borrowing close to a breakpoint and the larger amount fits your plan and your repayment capacity, ask the lender how the next tier would change the pricing.
How a lender builds the rate you're quoted
A variable 7(a) quote has two pieces: base rate + lender spread = your rate. The lender picks the spread based on its view of your credit, cash flow, collateral, time in business and how much it wants the deal. The only SBA requirement is that the result stays at or below the cap for your loan size.
To check a quote yourself, run through it in this order:
- Find the prime rate in effect on the first business day of the month SBA received (or will receive) your application.
- Add the spread cap for your loan amount from the table above. That gives you the legal ceiling.
- Compare it with the quoted rate. The gap between the two is the room you have to negotiate.
Worked example 1: a $500,000, 10-year variable loan. With prime at 7.00%, the cap is 7.00% + 3.0 = 10.00%. Say the lender quotes prime + 2.75, which is 9.75%. Fully amortized over 120 months, that comes to about $6,538 a month and roughly $284,600 in total interest. If the same loan were priced at the 10.00% cap, the payment would be about $6,608, around $70 more a month and about $8,300 more over the life of the loan. If prime were one point higher from day one (10.75%), the payment would be about $6,817.
Worked example 2: a $40,000 loan. The cap is 7.00% + 6.5 = 13.50%. A quote of 14% on a variable-rate 7(a) loan of this size would be above the regulatory maximum at today's prime. Ask the lender to show the base rate and spread they used, because the loan might not be an SBA loan at all.

The regulation for fixed rates, 13 CFR 120.213, says a loan may have a reasonable fixed interest rate and that SBA periodically publishes the maximum allowable rate in the Federal Register. SBA's lender page adds that the maximum fixed rates are posted on SBA's FTA Wiki. Check the most recent posting there for the current maximum allowable fixed rate for 7(a) loans, because SBA updates it from time to time. The fixed caps are a different schedule from the variable spreads above, so don't apply one to the other. Ask your lender which fixed maximum applied on the date SBA received your application.
What changes in practice is your payment. SBA's 7(a) borrower page says payments stay the same on fixed-rate loans because the rate is constant, while on variable-rate loans the lender may require a different payment when the rate changes. On a 10-year or 25-year loan, that difference adds up. A variable rate usually starts lower, and you take on the risk that prime goes up. A fixed rate gives you a payment you can budget around for the whole term.
Fees that sit on top of the rate
The interest rate doesn't cover everything you'll pay. 7(a) loans also carry an upfront SBA guaranty fee, and SBA resets it every fiscal year. SBA's FY 2027 7(a) Program Fees notice took effect October 1, 2026 and covers the guaranty fee, the lender's annual service fee and any exceptions for the year. Fee percentages from earlier fiscal years don't carry over, so ask your lender for the FY 2027 figure on your exact loan amount and maturity. Our guide to SBA loan fees and the guaranty fee explains how the fee is calculated on the guaranteed portion.
When you compare offers, turn the rate and fees into a total cost and a monthly payment. A slightly lower rate with heavier fees can cost more over a short holding period. How to compare business loan offers walks through that math.
How 7(a) pricing compares with SBA 504
The two programs are priced in very different ways. According to SBA's 504 loan page (checked October 2, 2026), 504 financing is long-term and fixed-rate for major fixed assets, with 10-, 20- and 25-year maturities, rates pegged to an increment above the current market rate for 10-year U.S. Treasury issues, and fees that total about 3% of the debt and can be financed with the loan. That page lists the maximum 504 loan as $5.5 million. 504 loans come through Certified Development Companies working alongside a senior lender. SBA's FY 2027 504 Program Fees notice, also effective October 1, 2026, sets that year's 504 guaranty fees.
| Feature | SBA 7(a) | SBA 504 |
|---|---|---|
| Rate basis | Prime (or Optional Peg Rate) plus a negotiated spread, capped by loan size | Fixed, pegged to the 10-year Treasury |
| Fixed or variable | Either | Fixed |
| Typical uses | Working capital, equipment, acquisitions, real estate, refinancing | Real estate and long-life equipment |
| Maximum term | 10 years generally; longer for equipment with a useful life over 10 years; up to 25 years for real estate | 10, 20 or 25 years |
The main trade-off is that 7(a) covers more uses and is quicker to structure, while a 504 locks in a long fixed rate on the SBA-backed portion. If you're buying a building, compare both side by side. See our SBA 504 loan rates guide and commercial real estate financing for how 504 projects are put together.
A quick check for any 7(a) quote
Go through this list before you sign:
- Base rate named? Prime, Optional Peg Rate or an approved alternative, and which month's figure was used.
- Spread stated? Get it as "prime + X" so you can check it against the cap.
- Under the cap? Use the spread cap for your exact loan amount.
- Fixed or variable? If variable, ask how often it adjusts and how the payment is recalculated.
- FY 2027 guaranty fee? Ask for the dollar amount and whether it's financed.
- Other costs? Packaging, closing and any prepayment terms, all in writing.
The caps are the same at every lender, but spreads aren't, and that gap is where comparing offers pays off. EQ Funding is a marketplace and doesn't lend. We send one application to lenders who compete for the deal, and each lender assesses your credit and repayment ability, so approval and terms vary by lender.
