Frequently asked questions
- What interest rate do SBA loans use?
- SBA 7(a) rates are tied to a base rate (commonly the prime rate) plus a lender spread the SBA caps — historically landing in roughly the high-single to low-double digits depending on loan size and term. 504 loans use a fixed rate tied to bond market pricing. Use the calculator to test the rate your lender quotes; this tool doesn't set or assume the SBA cap.
- How long are SBA loan terms?
- 7(a) terms run up to 10 years for working capital and equipment and up to 25 years for real estate. 504 loans are typically 10, 20, or 25 years. Longer terms lower the monthly payment but raise total interest — switch the term unit to years and watch both move.
- Does this include the SBA guarantee fee?
- No. The SBA charges a one-time guarantee fee (a percentage of the guaranteed portion) and lenders may add packaging or closing costs. Those are separate from the amortized principal-and-interest payment shown here — add the financed fee to the loan amount if your lender rolls it in.
