SBA loan basics
Short answer
Yes, SBA 7(a) loan interest rates can be either fixed or variable. Most are variable, tied to a base rate like the Wall Street Journal Prime Rate.
The SBA allows lenders to offer both fixed and variable interest rates. Variable rates are typically indexed to a widely published base rate (such as Prime Rate, Term SOFR, or a Treasury index) plus a fixed spread. Fixed rates remain constant for the loan's duration, offering predictability. Lenders disclose the options available.
A borrower may choose a variable rate of Prime + 2.75% for their loan, meaning their payments will fluctuate with the Prime Rate. Alternatively, they might opt for a fixed rate of 9.5% for the entire loan term, ensuring stable payments.
