Ten years in business banking before co-founding Lending Gurus. · Updated Nov 3, 2026
SBA loan rates aren’t set by the SBA in the way most people think. Your lender sets your rate. What the SBA does is cap how high that rate can go. For SBA 7(a) loans, the cap is a base rate, usually Prime, plus a maximum spread that depends on loan size and whether the rate is fixed or variable. This guide explains how those caps work, what they come to with Prime at 7.00% as of November 2, 2026, how 504 and microloan rates differ, and what else drives your cost. To see what a given rate means for your payment, use our SBA loan calculator.
Who sets SBA loan rates
The SBA says it plainly on its 7(a) page and lender page: lenders and borrowers negotiate the interest rate, but it may not exceed the SBA maximum. So two businesses can get very different rates on the same 7(a) program. One may land well under the cap, while another with weaker credit lands near it. Lending Gurus doesn’t set or quote rates. Lenders and partners do.
How the 7(a) maximum rate is built
Every 7(a) cap has two parts:
- The base rate. For fixed rate loans, the Federal Register notice says the cap uses “the Prime rate in effect on the first business day of the month.” Variable rate loans use an SBA allowed base rate, and the SBA publishes the current base rates each month.
- The spread. A maximum number of percentage points the lender can add on top. Smaller loans get a bigger allowed spread because they cost lenders more to make per dollar.
Maximum variable rates on 7(a) loans
Here are the variable rate caps as the SBA publishes them on sba.gov:
| Loan amount | Max variable rate | At Prime of 7.00% |
|---|---|---|
| $50,000 or less | Base rate + 6.5% | 13.50% |
| $50,001 to $250,000 | Base rate + 6.0% | 13.00% |
| $250,001 to $350,000 | Base rate + 4.5% | 11.50% |
| $350,001 and up | Base rate + 3.0% | 10.00% |
Maximum fixed rates on 7(a) loans
Fixed rate caps come from an SBA notice in the Federal Register (87 FR 46883), effective August 1, 2022. It applies to fixed rate 7(a) loans, including SBA Express and Export Express, but not Export Working Capital Program loans. The max is Prime plus:
| Loan amount | Max fixed rate | At Prime of 7.00% |
|---|---|---|
| $25,000 or less | Prime + 8% | 15.00% |
| $25,001 to $50,000 | Prime + 7% | 14.00% |
| $50,001 to $250,000 | Prime + 6% | 13.00% |
| Over $250,000 | Prime + 5% | 12.00% |
Where the 7.00% comes from. The Wall Street Journal Prime rate was 7.00% as of October 30, 2026, effective since September 17, 2026, and that’s the figure we used on November 2, 2026. The math in the right hand column is ours. When Prime moves, every cap moves with it, so check the current Prime rate before you compare quotes. These are ceilings, not quotes. A lender can charge less.
Rates on other SBA loans
- Export Working Capital Program. Per the SBA, “there is no SBA maximum interest rate limit” on EWCP loans. Lenders and borrowers negotiate it.
- SBA 504 loans. The SBA says the 504 rate is fixed and pegged to an increment above the current market rate for 10 year U.S. Treasury issues. Fees total roughly 3% of the debt and can be financed with the loan. Note that this covers the CDC portion. The bank loan in a 504 deal has its own rate. More in our SBA 504 loan guide.
- SBA microloans. Rates vary by intermediary lender and generally fall between 8% and 13%, per sba.gov. See our SBA microloan guide.
What else drives your SBA rate
Within the cap, lenders price on risk and cost. Things that usually move the needle:
- Credit. Personal and business credit history.
- Cash flow. How easily your business covers the payment.
- Collateral. More collateral can lower the lender’s risk.
- Loan size and term. Smaller loans have higher allowed spreads.
- Fixed vs variable. Variable payments can change when the base rate changes, per sba.gov. Fixed payments stay put.
- The lender itself. Banks, credit unions and nonbank SBA lenders price differently, which is why getting more than one quote is worth it.
Rate vs total cost
The rate is only part of what you pay. SBA loans can carry guarantee fees and lender closing costs, and 504 loans carry the roughly 3% in fees the SBA mentions. Always compare APR and total dollars repaid, not just the rate. Our APR vs interest rate guide shows how a fee changes the math, and business loan interest rates puts SBA pricing next to other loan types.
Illustrative example. Take a $300,000 fixed rate 7(a) loan. With Prime at 7.00%, the most the lender can charge is 12.00% (Prime plus 5). A quote of 10.5% is under the cap. A quote of 12.5% is over it, and you should ask why. Run both rates through the calculator at your term to see the payment gap in dollars.
How to check a quote against the cap
- Ask whether the rate is fixed or variable, and which base rate it uses.
- Find your loan size row in the tables above.
- Add the max spread to the current Prime rate.
- Compare that ceiling with your quote, then ask for the APR and full fee list.
If you need to compare outside SBA too
If an SBA loan takes too long for your timeline, you can compare multiple business funding offers through 1West. Non SBA options aren’t covered by these caps and often cost more, so put every quote in total dollars before you decide. Partners make all funding decisions.
FAQ
What is the current SBA loan rate?
There isn’t one SBA rate. Lenders set rates under SBA caps. With Prime at 7.00% as of November 2, 2026, the 7(a) variable caps run from 10.00% to 13.50% and the fixed caps from 12.00% to 15.00%, depending on loan size.
Are SBA rates fixed or variable?
7(a) loans can be either. 504 loans carry a fixed rate on the CDC portion. Microloan rates are set by the intermediary lender.
Do SBA rates change every month?
The caps are tied to base rates that the SBA uses as of the first business day of the month, so caps can move when Prime moves. A fixed rate loan stays fixed once it closes.
Is the SBA cap the rate I’ll get?
Not necessarily. The cap is a ceiling. Your lender can offer less based on your credit, cash flow and collateral.
Does Lending Gurus set SBA rates?
No. Lending Gurus is a referral service. Lenders set rates within SBA rules.
