SBA 7(a) Q&A
Short answer
SBA 7(a) loan interest rates can be either fixed or variable. Variable rates are more common and are typically indexed to the Prime Rate, though other base rates like SOFR or LIBOR (for older loans) may also be used.
SBA 7(a) loans have interest rates that are either fixed for the life of the loan or variable. Variable rates are tied to a market index plus a lender's spread. The Prime Rate, as published in the Wall Street Journal, is the most common base rate for variable rate 7(a) loans. The maximum allowable interest rate is determined by the base rate plus a maximum spread, which is set by the SBA and varies based on the loan amount and term.
For a $700,000 SBA 7(a) loan, your lender might offer a variable rate of Prime + 2.75%. If the Prime Rate is 8.50%, your initial interest rate would be 11.25%, adjusting as the Prime Rate changes.
