Why a smaller SBA 7(a) loan can cost more: the spread is capped by size
The SBA does not set the rate on a 7(a) loan. It sets the maximum spread a lender may add over a base rate, and that maximum steps down three times as the loan gets bigger. The largest step, at $350,000, is 1.5 points.
A 7(a) loan is made by a bank, not by the SBA. What the SBA controls is the ceiling: the most a lender may charge over a published base rate. That ceiling is set by loan size, and it is widest on the smallest loans, which is why a $40,000 7(a) loan can carry a higher rate than a $400,000 one from the same lender.
| Loan amount | Maximum variable rate | The spread, alone |
|---|---|---|
| $50,000 or less | Base rate plus 6.5% | 6.5 points |
| $50,001 to $250,000 | Base rate plus 6.0% | 6.0 points |
| $250,001 to $350,000 | Base rate plus 4.5% | 4.5 points |
| Greater than $350,000 | Base rate plus 3.0% | 3.0 points |
The maximum loan amount for a 7(a) loan is $5 million. SBA Express, one of the delivery methods, is capped at $500,000.
Maximum spread over the base rate, by loan size (percentage points)
These are ceilings on the variable rate, not the rate you will be offered. A lender may charge less. The steps are the SBA's own tiers.

The step that matters is at $350,000
Between the smallest tier and the largest, the permitted spread more than halves, from 6.5 points to 3.0. The single largest step is at $350,000, where the ceiling drops by 1.5 points at once.
On a loan of that size, 1.5 points is $5,250 a year of interest at the ceiling (1.5% of $350,000), before any amortization. The step is large enough that a bigger loan can carry less interest than a smaller one. Take a requirement of $340,000 against a loan of $355,000, both priced at the ceiling. The spread alone costs 4.5% of $340,000, or $15,300 a year, on the smaller loan, and 3.0% of $355,000, or $10,650, on the larger: $4,650 less. The extra $15,000 of principal costs the base rate on $15,000, which only reaches $4,650 if the base rate is 31%. At any base rate a 7(a) lender actually uses, the larger loan is the cheaper one in dollars, as long as the extra $15,000 has a use. With a lender's quoted spreads in place of the ceilings the gap can be smaller, or gone, so the comparison has to be run on the figures in the two offers, not on the table.
The reverse is the more common trap. Trimming a $360,000 request to $345,000 to look conservative moves you into a tier where the lender may charge 1.5 points more.
These are ceilings, not offers
Nothing here says a lender will charge the maximum. The SBA maximum is a regulatory ceiling, not a negotiating floor: the rate is negotiated with the lender and may be lower, and two lenders quoting the same loan size can sit at different spreads within the same tier. A variable-rate offer is only readable when the lender states the base rate it is using, the spread it is adding, and the effective date of that base rate, because the ceiling in the table is a limit on the spread, not on the whole rate.
The two numbers that come from SBA, not from the lender
The rate ceilings above are only half of an offer. The other half is a base rate and a fee schedule, and both are published by SBA rather than set by your lender. We do not reprint either here, because both are replaced on a schedule and a stale figure reads as a current one.
Where these come from
The current base rate for 7(a). The rate you pay is a base rate plus the spread. SBA ties the variable-rate maximum to permitted base rates and publishes current rate resources through its Fiscal Transfer Agent. The lender can tell you which base rate applies, what it is today, and the effective date of that figure.
The FY2026 fees. SBA publishes the upfront fee and the lender's annual service fee each fiscal year through an Information Notice. The current one is 5000-872051, 7(a) Fees Effective October 1, 2025 for Fiscal Year 2026, issued 28 August 2025. The tier that applies depends on your loan amount and maturity, so the notice is worth reading by number rather than taking a summary. Two of SBA's rules decide who pays: the lender pays the upfront fee and is permitted to pass it on to the borrower, and the lender's annual service fee cannot be charged to the borrower.
The maximum fixed rates. Not on sba.gov. SBA's own 7(a) page says it "publishes the maximum fixed interest rates on SBA's FTA wiki", and the wiki carries them as a monthly spreadsheet headed New Maximum Allowable Fixed Rate for 7(a) Loans. A fixed-rate offer can be checked against that month's sheet for your loan size; the address is in the sources below.
The upfront fee matters more than its name suggests. It is a percentage of the guaranteed portion, charged at the start, and it scales with the loan, so on a large loan it is a sum that a comparison of rates alone leaves out. A fee quoted from an earlier year's notice is simply the wrong number for a loan closing in this one.
So what do you do
If your requirement is near $350,000, price it both sides of the line before you choose the amount. On the published ceilings the tier change is 1.5 points; the question is whether the lender's actual discount below the ceiling is larger or smaller than that.
If your requirement is under $50,000, the permitted spread is the widest in the program, and the fees and paperwork are the same kind of work as on a larger loan. A smaller conventional facility, or a card-based facility repaid quickly, can come out cheaper on total dollars, and the comparison is on total dollars, not on the rate.
If you are comparing two 7(a) offers, the three figures that make them comparable are the base rate and its current value, the spread, and every fee in dollars rather than percentages. Add the fees to the principal and recompute. On a short maturity a half-point of spread can be smaller than the difference in upfront fees, so the spread alone does not rank the offers. Both lenders are working under the same ceiling.
If a lender will not state the base rate and spread separately, you do not yet have an offer you can compare, whatever the headline rate.
Who should not use this route
7(a) is a documentation-heavy product with a real time cost. If you need funds within two weeks, or the amount is small enough that the paperwork exceeds the interest saved, the program is not the efficient answer even where its rate ceiling is lower than the alternatives.

8 September 2026 New — The page now says where SBA's maximum fixed rates are published rather than only that they are published elsewhere. SBA's own 7(a) terms page points at its Fiscal Transfer Agent wiki, which posts them as a monthly spreadsheet. We still do not re-key the figure, because it is replaced every month.
6 September 2026 Correction — The SBA fee notice for the 2026 fiscal year was described as unobtainable. It is Information Notice 5000-872051, issued 28 August 2025, and it is now cited by number.
