SBA 7(a) Q&A
Short answer
The primary factor determining the interest rate on an SBA 7(a) loan is the chosen base rate (like Prime Rate) plus a variable spread determined by the lender based on loan size and risk.
SBA 7(a) loan rates are variable and capped at a maximum spread over a base rate (e.g., Prime Rate, WSJ Prime, SOFR). Lenders select a base rate and then add a spread based on their assessment of the borrower's creditworthiness, the loan amount, and the term, while staying within SBA's maximum allowable rates.
If the Prime Rate is 8.50%, a lender might offer an interest rate of Prime + 2.00% (10.50%) for a strong borrower with a large loan, but Prime + 2.75% (11.25%) for a borrower with higher perceived risk.
