SBA 7(a) Q&A
Short answer
The fixed interest rate for an SBA 7(a) loan is determined by adding a fixed spread to an approved base rate (typically Prime Rate) and is influenced by market conditions, the lender's risk assessment, and the loan's term.
SBA 7(a) loans can have either fixed or variable interest rates. For fixed rates, the lender sets a spread (margin) above an approved base rate (e.g., Prime Rate, SOFR, or Term SOFR). This fixed spread remains constant for the life of the loan. Factors influencing the spread include the lender's internal cost of funds, the perceived risk of the borrower, the loan amount, and the chosen repayment term. The SBA sets maximum allowable rates.
If the Prime Rate is 8.50%, a lender might offer you an SBA 7(a) loan with a fixed rate of Prime + 2.75%, resulting in a fixed interest rate of 11.25% for the entire loan term, regardless of future Prime Rate changes.
