SBA 7(a) Q&A
Short answer
The maximum interest rate on an SBA 7(a) loan is capped by the SBA and is tied to a base rate (Prime Rate, WSJ Prime, SOFR) plus a maximum allowable spread.
SBA sets maximum interest rates, which are variable and generally cannot exceed Prime Rate (or equivalent base rate) plus 2.25% to 4.75%, depending on the loan amount and term. These caps ensure affordability and prevent predatory lending. The exact rate will depend on the market and your lender's policies.
If the Prime Rate is 8.50%, a typical maximum interest rate for a loan over $50,000 could be Prime + 2.75%, resulting in 11.25%. Smaller loans or longer terms may have different maximum spreads.
