The quick read: It depends on how much payment risk the business can carry. A variable SBA 7(a) loan reprices with prime, and the Wall Street Journal's money-rates table lists U.S. prime at 7.00% with an effective date of 9/17/26, the day the Fed's quarter-point increase took effect. The minutes of the Fed's September 15-16, 2026 meeting say "most participants assessed that another increase in the target range for the federal funds rate would likely be appropriate by year end." A fixed rate removes that path, but SBA allows a higher maximum for it: above $350,000, the fixed cap sits 2 points over the variable cap. On October 28, 2026, the Fed held the federal funds target range at 3.75% to 4.00%, and its H.15 release showed prime still at 7.00% that day.
How is the maximum variable rate on an SBA 7(a) loan set?
SBA sets the maximum variable rate on a 7(a) loan as a base rate, prime or an optional peg rate, plus a spread that shrinks as the loan gets larger, from 6.5 points on loans of $50,000 or less to 3.0 points on loans above $350,000. The lender and borrower negotiate the actual rate at or below that ceiling.
SBA's terms page prints the caps, and the regulation at 13 CFR 120.214 sets the mechanics:
$50,000 or less (SBA): base rate plus 6.5%
$50,001 to $250,000 (SBA): base rate plus 6.0%
$250,001 to $350,000 (SBA): base rate plus 4.5%
Greater than $350,000 (SBA): base rate plus 3.0%
When the cap is set (13 CFR 120.214): the initial maximum is determined as of the date SBA receives the loan application
Adjustment frequency (13 CFR 120.214): first change on the first calendar day of the month after initial disbursement, then no more often than monthly
Base rate date (13 CFR 120.214): the prime rate in effect on the first business day of the month
Size of each change (13 CFR 120.214): equal to the movement in the base rate
Two details in the rule matter when you read a note. First, the spread does not move; only the base rate does, so a prime change passes straight through to the rate. Second, if the note has a ceiling, the rule says the ceiling can be no farther above the starting rate than the floor is below it. The rule also lets SBA direct that amortization be recomputed as rates change, and it bars balloon payments. The SBA 7(a) glossary entry covers the program basics.
Where are SBA's fixed-rate maximums published, and how do they compare?
SBA's terms page says the agency "publishes the maximum fixed interest rates on SBA's FTA wiki," and its August 1, 2022 Federal Register notice sets the method: prime in effect on the first business day of the month plus 8, 7, 6 or 5 points, depending on loan size. Above $250,000, the fixed spread is 5 points.
The regulation at 13 CFR 120.213 says a 7(a) loan may have a reasonable fixed rate and that SBA periodically publishes the maximum in the Federal Register. The 2022 notice applies to complete applications SBA receives, or loan numbers lenders request under delegated authority, from August 1, 2022, and says future revisions will be published in the Federal Register and posted monthly on SBA's website. Confirm with your lender which month's maximum applies to your application.
Here is how the two sets of caps line up at 7.00% prime, with an illustrative payment for one loan in each band. The rates are maximums, not quotes, and the arithmetic is ours:
| Attribute | $25,000 or less | $25,001 to $50,000 | $50,001 to $250,000 | $250,001 to $350,000 | Over $350,000 |
|---|---|---|---|---|---|
| Attribute Max variable spread (SBA) | $25,000 or less 6.5 points | $25,001 to $50,000 6.5 points | $50,001 to $250,000 6.0 points | $250,001 to $350,000 4.5 points | Over $350,000 3.0 points |
| Attribute Max variable rate at 7.00% prime | $25,000 or less 13.50% | $25,001 to $50,000 13.50% | $50,001 to $250,000 13.00% | $250,001 to $350,000 11.50% | Over $350,000 10.00% |
| Attribute Max fixed spread (2022 notice) | $25,000 or less 8 points | $25,001 to $50,000 7 points | $50,001 to $250,000 6 points | $250,001 to $350,000 5 points | Over $350,000 5 points |
| Attribute Max fixed rate at 7.00% prime | $25,000 or less 15.00% | $25,001 to $50,000 14.00% | $50,001 to $250,000 13.00% | $250,001 to $350,000 12.00% | Over $350,000 12.00% |
| Attribute Illustrative loan amount | $25,000 or less $25,000 | $25,001 to $50,000 $50,000 | $50,001 to $250,000 $250,000 | $250,001 to $350,000 $350,000 | Over $350,000 $1,000,000 |
| Attribute Monthly payment at max variable, 25 years | $25,000 or less $291 | $25,001 to $50,000 $583 | $50,001 to $250,000 $2,820 | $250,001 to $350,000 $3,558 | Over $350,000 $9,087 |
| Attribute Monthly payment at max fixed, 25 years | $25,000 or less $320 | $25,001 to $50,000 $602 | $50,001 to $250,000 $2,820 | $250,001 to $350,000 $3,686 | Over $350,000 $10,532 |
The table shows where the choice bites. From $50,001 to $250,000 the two caps are identical. From $250,001 to $350,000 the fixed cap is half a point higher. Above $350,000, the fixed cap is 2 points higher, which at the maximum is about $1,445 a month on a $1,000,000 loan over 25 years. Your negotiated rates will sit at or below these ceilings, and the real gap between a lender's fixed and variable quotes is the number to compare.
What did the September prime increase add to a $1 million variable 7(a) payment?
On a $1,000,000 variable 7(a) loan amortizing over 25 years at the maximum spread of prime plus 3.0 points, the move to 7.00% prime raised the rate from 9.75% to 10.00%. That lifted the monthly payment from about $8,911 to about $9,087, roughly $176 a month or $2,108 a year (our arithmetic).
SBA allows real estate terms of up to 25 years including extensions, which is why these illustrations amortize over 25 years. The size of the change barely depends on your spread, because the spread does not move. At spreads from 1.5 to 3.0 points over prime, the same quarter point adds roughly $168 to $176 a month on $1,000,000 over 25 years (our arithmetic). What changes with the spread is the starting payment, not the step.
The dated record behind those numbers:
FOMC statement (September 16, 2026): raised the target range "by 1/4 percentage point to 3-3/4 to 4 percent"
Interest on reserve balances (FOMC minutes): raised to 3.90%, effective September 17, 2026
U.S. prime (WSJ money-rates table, October 20, 2026): 7.00%, effective date 9/17/26, 52-week low 6.75%
Bank prime loan rate (Federal Reserve H.15 weekly averages): 6.75% in the week ending September 16, 2026, then 7.00% in each week from September 23 to October 14, 2026
Because 13 CFR 120.214 resets the base rate from prime on the first business day of the month, a note that adjusts monthly picked up the change at its first adjustment after September 17. A note that adjusts quarterly picks it up at the next quarter. Your note's adjustment dates decide when, not whether.
What do the September FOMC minutes say about where prime could go next?
The minutes of the September 15-16, 2026 FOMC meeting, released October 7, say most participants assessed that another increase in the federal funds target range would likely be appropriate by year end. Participants also emphasized that decisions at future meetings would depend on incoming information and its implications for the outlook.
That is the Committee's own characterization, not a forecast from this page. On October 28, 2026, the Committee kept the target range at 3-3/4 to 4 percent in a 10-2 vote, and the two dissenters, Lisa D. Cook and Beth M. Hammack, preferred a quarter-point increase. Two other lines in the minutes matter for a borrower choosing a structure. The manager's market report said nominal yields "increased around 35 basis points across the 2- to 10-year segment of the yield curve," and longer yields matter to fixed-rate pricing, while a variable 7(a) rate follows prime. The minutes also record the Board raising interest on reserve balances to 3.90%, effective September 17, 2026, the same date prime moved on the WSJ table.
Prime itself is set by banks. The Fed's H.15 release describes it as the rate posted by a majority of the top 25 insured U.S.-chartered commercial banks, and in September it moved on the same effective date as the Fed's target range on the WSJ table. If prime moves again, a variable 7(a) payment follows at the note's next adjustment date.
Which owner-users should choose a fixed rate on an SBA 7(a) loan?
Owner-users should fix the rate when the business cannot absorb a higher payment, plans to hold the property for many years, or has thin debt coverage. Variable is worth a look when cash flow has room for increases and the lender's fixed quote carries a wide premium over its variable quote for the same loan.
A practical way to decide is to stress the variable payment, not to guess the rate path:
- Rerun the variable payment at prime plus one or two more quarter-point steps and check coverage at each level.
- Compare that stressed payment with the lender's actual fixed quote, not with the SBA maximum.
- Read the note's adjustment frequency, floor and any ceiling before you sign.
- Check the prepayment terms. SBA's terms page says loans with a maturity of 15 years or longer carry a prepayment fee when the borrower voluntarily prepays 25% or more in the first three years: 5% in year one, 3% in year two and 1% in year three.
That last point cuts against one tempting plan: taking variable now and refinancing into a fixed loan later. On a 25-year real estate loan, an early refinance inside the first three years pays that fee. If the property is the business's long-term home, the SBA 504 vs 7(a) comparison shows when a 504 loan's fixed CDC portion is the better fit, and the SBA 504 and 7(a) rates page explains how each program is priced.
How do you get an SBA 7(a) loan placed on the rate structure you want?
You get an SBA 7(a) loan placed on the right structure by asking lenders to quote the same deal both ways, fixed and variable, with the spread, adjustment frequency, any floor or ceiling and the prepayment terms written out. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors.
Three ways to get both quotes, with the brokerage route first:
- A commercial mortgage brokerage. YieldStack's software matches the deal against a catalog of 20,000+ loan programs. Human brokers then structure the request, negotiate spread, structure and term on the borrower's side and carry the deal toward closing. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
- Your own bank's SBA desk. You see one lender's fixed and variable pricing, and the comparison across lenders is your own work.
- Going direct to several SBA lenders one at a time. You collect each quote yourself and line up the terms so they compare.
Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed. Send the purchase contract, three years of business financials, the debt schedule and the payment you can carry, then submit the SBA purchase for review. The SBA loan page covers both SBA programs.
The bottom line
Choose variable on an SBA 7(a) loan only if the business can carry the payment after more prime increases; choose fixed if it cannot. With prime at 7.00% as of October 20, 2026, the variable cap above $350,000 is 10.00% and the fixed cap is 12.00%, so compare real quotes and the prepayment terms before you sign.
