Most owners size up an SBA loan by its interest rate and stop there. The rate matters, but it’s only part of the bill. Between the SBA’s guarantee fee, lender charges, and third-party costs, the true cost of borrowing is higher than the headline number. Here’s the full picture so you can plan and compare offers accurately.
Interest rates by program
The SBA doesn’t set rates — lenders do, within SBA maximums, usually tied to the prime rate.
- 7(a) loans: Rates can be fixed or variable. The SBA caps the markup over prime, with smaller loans allowed a higher spread than larger ones. When the prime rate is high, total rates on smaller 7(a) loans can land in the low-to-mid teens.
- 504 loans: The CDC portion carries a long-term fixed rate based on Treasury bonds plus a spread, which often comes in lower than a comparable 7(a). The lender portion is negotiated separately.
Always confirm the current prime rate and the lender’s actual quote — these numbers move.
SBA guarantee fees
The SBA charges a guarantee fee to support the program, based on loan size and maturity.
- For 7(a) loans, the fee scales with the loan amount and applies to the guaranteed portion. The SBA periodically waives or reduces this fee for smaller loans, so check the current schedule.
- 504 loans carry a processing fee and a closing fee, each a small percentage of the debenture.
Guarantee fees can often be financed into the loan rather than paid out of pocket.
Lender and third-party closing costs
Lenders add their own charges, and some costs come from outside parties:
- Lender fees: origination (commonly a low single-digit percentage of the loan), underwriting, and sometimes a commitment fee.
- Third-party costs: business appraisal, environmental reports when real estate is involved, title insurance, and recording fees. Your own attorney to review documents adds more.
These third-party costs are typically paid at closing and usually can’t be financed, so plan to have cash ready.
Packaging and consulting fees
Many owners hire a packaging specialist to handle the paperwork-heavy application. Fees are usually a small percentage of the loan or a flat rate. It’s optional — but a good specialist can improve your odds and save time. Clarify the fee structure upfront, and only work with someone reputable.
How it adds up
Here’s the shape of the total cost on a hypothetical $100,000 SBA 7(a) loan over a 10-year term:
| Cost | Notes |
|---|---|
| Guarantee fee | May be reduced/waived for smaller loans |
| Lender origination | Low single-digit % of the loan |
| Third-party closing | Appraisal, legal, etc. — paid at closing |
| Packaging (optional) | Small % of the loan |
| Interest over the term | The largest cost by far |
The upfront cash you’ll need is the sum of the fees; the interest over the life of the loan is usually the biggest single line. On a larger 504 loan for real estate, the fixed rate on the CDC portion typically lowers the long-run interest cost compared to financing the whole amount at a 7(a) rate.
These are illustrations, not quotes — your actual numbers depend on the loan, the lender, and current rates.
How to keep the cost down
- Negotiate lender fees. Origination and underwriting charges are sometimes flexible.
- Shop multiple SBA-approved lenders and request a detailed fee schedule from each to compare apples to apples.
- Plan for non-financeable costs by having cash reserves ready for third-party fees.
- Consider a shorter term. Payments rise, but total interest drops.
- Watch the prime rate. If rates are expected to fall, a variable 7(a) may get cheaper over time.
Bottom line
The interest rate is only the start. Fees and closing costs add to your upfront cash needs, and interest over the term is usually the largest cost of all. Get a full, written fee breakdown from every lender you talk to before you commit.
