How SBA Loan Rates Are Calculated
SBA 7(a) loan rates are not set by the SBA. The SBA sets maximum allowable spreads above the Prime Rate, and lenders charge whatever they want within those limits. The formula is simple: Prime Rate + Lender Spread = Your Rate.
With Prime currently at 6.75%, a lender charging the maximum spread of 2.75% on a loan over $50,000 with a term over 7 years would quote you 9.50%. That's the ceiling. Most loans land somewhere in the 9.00 to 9.50% range right now.
The SBA maximum spreads depend on loan size and term:
| Loan Amount | Term ≤ 7 years | Term > 7 years |
|---|---|---|
| $0 to $25,000 | Prime + 4.25% | Prime + 4.75% |
| $25,001 to $50,000 | Prime + 3.25% | Prime + 3.75% |
| $50,001 and above | Prime + 2.25% | Prime + 2.75% |
Most small business loans fall into that bottom row — loans over $50,000, terms over 7 years. At today's Prime Rate of 6.75%, that puts the ceiling at 9.50%. Lenders can charge less, but can't charge more.
Fixed vs. Variable: What Most Borrowers Get
The majority of SBA 7(a) loans are variable rate — meaning your rate adjusts quarterly or annually as Prime moves. Fixed-rate SBA loans exist but are less common. SBA 504 loans, which are used for real estate and equipment, typically carry fixed rates set at the time of closing.
Variable rates start lower, which helps your DSCR calculation at origination. But as the Fed raises rates, your payment rises with it. The rate ceiling protects you from the worst-case scenario — but there's still real payment risk in a rising rate environment. Read the full breakdown →
SBA Loan Rate History (2018–2026)
Rates have moved dramatically over the past several years. Understanding where we've been puts today's 9.75 to 11.75% in context — it's elevated compared to pre-pandemic levels but well below the 2023 peak.
The 2023 peak of ~11.50% is the key data point for anyone evaluating variable rate risk. Businesses that closed SBA loans at 3.25% in 2021 and didn't lock a fixed rate watched their payments jump substantially when Prime moved from 3.25% to 8.50% in under 18 months. That's the rate ceiling's job — to cap the damage. Read more about the ceiling →
The rate ceiling on SBA 7(a) loans isn't a guarantee of a low rate — it's a cap on how high your rate can go. At today's Prime of 6.75%, the ceiling is 9.50% on standard loans. If Prime rises to 9.00%, the ceiling rises with it to 11.75%. The ceiling moves. It just moves with the market, not ahead of it.
How the Fed Rate Connects to Your SBA Payment
The Federal Reserve doesn't set the Prime Rate directly — it sets the federal funds rate, which is the rate banks charge each other for overnight loans. The Prime Rate has historically tracked 3 percentage points above the federal funds rate. When the Fed moves, Prime moves the same day.
As of June 2026, the Fed funds rate is 3.75%, making Prime 6.75%. The Fed has cut rates four times since late 2024, bringing Prime down from its 8.50% peak. Markets currently expect rates to stay relatively stable through the rest of 2026. See how future Fed moves could affect your payment →
What Rate Should You Put in Your DSCR Calculation?
When calculating whether you can afford an SBA loan, use the current rate — but stress-test at the ceiling. If your DSCR is tight at 9.50%, be cautious. The best underwriters in the country think about rate sensitivity before they close: how much does Prime have to rise before this borrower can't cover their payments?
A simple rule: if your DSCR falls below 1.10x when you run the numbers at Prime + 3%, reconsider the loan size or structure before applying.
