SBA 7(a) Q&A
Short answer
The maximum interest rate a lender can charge for an SBA 7(a) loan is capped by the SBA and is based on a base rate (like Prime Rate) plus a maximum allowable spread.
The SBA sets maximum allowable interest rates for 7(a) loans, which are typically variable rates. The rate is calculated as an approved base rate (e.g., Wall Street Journal Prime Rate, Term SOFR) plus a maximum spread determined by the loan amount and maturity. Lenders cannot exceed these caps.
If the Prime Rate is 8.50%, and for a loan over $50,000 with a term of more than 7 years, the maximum spread is 2.75%, the highest interest rate your lender could charge you would be 11.25% (8.50% + 2.75%).
