SBA loan basics
Short answer
SBA 7(a) loan interest rates can be either fixed or variable, depending on the loan agreement with the lender. Most lenders offer variable rates, which adjust periodically based on a chosen base rate plus a spread.
The SBA allows both fixed and variable interest rates for 7(a) loans. For variable rates, the rate is tied to a base rate (such as the Prime Rate, SOFR, or Term SOFR) plus a negotiated spread, and it can adjust quarterly, semi-annually, or annually. The SBA sets maximum allowable spreads.
A borrower might secure a variable-rate loan at Prime + 2.75%. If the Prime Rate increases from 7.00% to 7.50%, their new interest rate would become 10.25%. A fixed-rate loan, once set, would remain constant for the life of the loan.
