How SBA maximum interest rates are built: a spread over a base rate, not a fixed number
There is no SBA rate. There is a ceiling made of a published base rate plus a maximum spread, and your lender picks where under that ceiling to sit.

Anyone who quotes you "the SBA rate" as a single number is either simplifying badly or selling. The SBA does not set a rate. It sets a maximum, and the maximum is built out of two moving parts.
The two parts
Your maximum rate is base plus the applicable spread. When the base rate moves, the ceiling moves with it. This is the reason a loan approved in one quarter can carry a different rate from an identical loan approved in the next.
The current permitted base rates and maximum spreads are published by the SBA and revised over time. Get them from sba.gov, not from a broker's email.
The ceiling is not the rate you get
This is the part that saves money. The spread is a maximum, not a schedule. A lender can charge less, and lenders compete on exactly this. A strong borrower with real estate collateral and a lender that wants the relationship does not pay the same spread as a marginal start-up.
So the useful question is never "what is the SBA rate." It is: what base rate are you using, what spread are you adding, is it fixed or variable, and how often does it reset? Ask it exactly that way, and ask two or three lenders.
Fixed versus variable
Most 7(a) loans are written variable, tied to the base rate with a defined adjustment period — monthly, quarterly, or another interval set in the note. Some lenders will write fixed, and the SBA permits fixed-rate 7(a) loans within a separate maximum.
The trade is the usual one, with an SBA wrinkle. A variable 7(a) with a long amortization means your payment can rise for years and there is no balloon date at which you get to refinance out. Model the payment at a materially higher base rate before you accept variable. If the business does not survive that model, say so at term sheet stage while a fixed quote is still available to ask for.
On a 504, the debenture piece is fixed at the time the debenture is priced and sold, for the life of that loan. The bank's first mortgage is on the bank's own terms, and it is frequently variable, or fixed for a period and then repriced. A 504 is not "a fixed-rate loan" — one piece of it is.
What else is in the cost, beyond the rate
Rate comparisons between lenders can be defeated by everything that is not the rate.
- The guaranty fee, which the lender may pass to you and which is usually financed.
- The packaging fee, where the lender charges one, and any agent fee disclosed on the SBA fee disclosure form.
- Third-party costs: appraisal, environmental report, title, survey, business valuation, filing fees.
- The prepayment charge, which on a long-maturity 7(a) is set by statute and on a 504 attaches to the debenture and to the bank's first mortgage separately.
Two offers at the same spread are not the same offer if one finances several thousand dollars of fees into the balance and the other does not.
What "model the payment higher" means in dollars
That is $693.57 more a month and $8,323 more a year, on the same balance, with no change to the business. If the business generates $150,000 of cash available for debt service and this is its only facility, coverage falls from about 2.32 to about 2.05 — survivable. At $95,000 of cash available it falls from 1.47 to 1.30, which is close enough to most policy floors to matter at the next renewal or the next application.
Two mechanical points about how a reset lands. Most variable notes re-amortise the remaining balance over the remaining term, so a rate rise shows up as a higher payment rather than a longer loan. Some instead hold the payment and extend, which changes the cash-flow answer entirely. The note says which, and it is worth knowing before the first adjustment date rather than after it.
What the SBA restricts, and what it does not
The SBA caps the rate and restricts several fees. It does not require lenders to price uniformly, does not publish a rate you are entitled to, and does not intervene in your pricing negotiation. Pricing is a market, inside a ceiling.
The secondary market is worth understanding here. Lenders can sell the guaranteed portion of a 7(a) loan to investors, and the premium they earn depends partly on the loan's rate. That is a genuine reason a lender may prefer to price near the ceiling. It changes nothing about your legal position, but it tells you that asking for a lower spread is a commercial conversation, not an appeal for a favor.
How to run the comparison
- Get each offer expressed as base rate plus spread, with the base rate named and the reset frequency stated.
- Ask for fixed and variable quotes from the same lender.
- Ask for a full fee list, split into lender fees and third-party pass-throughs.
- Ask what the payment would be if the base rate rose several points, and get it in writing.
- Compare total cost over the term you actually expect to hold the loan, including the prepayment charge if you might exit early.
If a lender will not put base rate, spread, reset frequency and fees in a single written document, that is information about the lender.
Where this applies

What does this guide cover?
There is no SBA rate. There is a ceiling made of a published base rate plus a maximum spread, and your lender picks where under that ceiling to sit.
Which funding products does this apply to?
Term Loan, SBA Loan. Each has its own page listing the funders in this directory that offer it and what each one publishes about its terms.
Are the figures here quotes?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What a particular lender charges is on that lender's page, where it publishes it at all.
Who writes this?
The Find Me Funders research desk. Some drafting is AI-assisted, and every page that is says so at the top, including whether a person has checked its claims yet.
How do I know a figure here is right?
Where a page carries the green notice, its claims were checked against the sources listed at the end and a reviewer is named. Where it carries the amber one, nobody has verified it yet and you should confirm anything you plan to act on.
Are the examples real deals?
No. Every worked example is labelled illustrative and exists to show the arithmetic. What any particular lender charges is on that lender's page, where it publishes it.
Why do you never say what a typical rate is?
Because we cannot source it. A market average assembled from lenders who do not publish prices is a guess with a decimal point on it. Where a lender publishes a figure, we show that figure and say where it came from.
Is this financial or legal advice?
No. It is general information about how these products work. Outcomes depend on your contract and your state, and a lawyer or accountant licensed where you are is the person to ask about your situation.
