The four layers, at a glance
| Layer | What it is | When you pay it |
|---|---|---|
| Interest rate | Prime plus a lender spread, variable | Every month, for the life of the loan |
| Upfront guarantee fee | The SBA’s charge for the guarantee, tiered by loan size | At closing, often financed into the loan |
| Annual service fee | A fee on the guaranteed portion of larger loans | Annually, where it applies |
| Closing costs | Appraisal, environmental, title, recording | At closing, to third parties |
Layer one: the rate
Rates are built as prime plus a spread, with the SBA capping the spread by size bracket. At prime of 7.00% (verified September 17, 2026, FRED series DPRIME), modeled rates in the high 9s to low 10s correspond to spreads in the 2.5 to 3.5 point range; your actual spread depends on the deal. The construction mechanics, caps and why quotes differ are in how SBA interest rates work.
Layer two: the upfront guarantee fee
When a 7(a) loan closes, the SBA charges the lender a fee for the guarantee, and lenders pass it through to borrowers. It is tiered: a percentage of the guaranteed portion of the loan, stepping down as the loan gets larger. For context, the sba generally guarantees 85% of loans of $150,000 or less and 75% of larger loans. confirm current percentages with your lender. The FY2026 tier table is published in SBA Information Notice 5000-872051, and rather than reproduce a table you could misread, the guarantee fee calculator computes the exact fee for your amount from the current file.
Borrowers usually finance the fee into the loan rather than pay it in cash. That spreads it over the term, which is convenient and slightly more expensive: you pay interest on the fee. Both options are modeled side by side in the example below.
If the loan is paid off very early, a portion of the guarantee fee may be refundable through the lender. The mechanics are narrow; ask the question before you close, not after.
Layer three: ongoing fees
Larger 7(a) loans can carry an annual service fee on the guaranteed portion, set by the SBA and collected by the lender. On smaller loans it does not apply. Your lender will disclose whether yours does; ask for the number explicitly and put it in your first-year math rather than discovering it on a statement.
Layer four: closing costs
Appraisal, environmental review, title, recording and legal work are charged by third parties, and the SBA requires several of them for real estate deals. On mid-size loans these commonly run a few thousand dollars, and real estate transactions can run higher depending on the property. They are negotiable with the vendors, not with the lender, and they are paid in cash at closing even when the guarantee fee is financed.
A complete first-year example
Both structures are legitimate; the difference is liquidity now versus a slightly higher payment for a decade. Run your own amount through the 7(a) payment calculator, which handles the fee financing effect automatically.
What to compare across lenders
- The spread, in writing: “prime plus X”, not a promo rate.
- Whether the quoted payment includes the financed guarantee fee or assumes it in cash.
- All third-party fees, itemized, before you commit.
- Turnaround time for a complete file, in weeks. Speed has real value that a 0.1-point spread difference can erase.
