SBA loan basics
Short answer
SBA 7(a) loan interest rates can be either fixed or variable. The choice depends on the lender's offerings and the specific loan product, but variable rates are more common.
The SBA permits both fixed and variable interest rates for 7(a) loans. For variable rate loans, the rate is tied to a base rate (like Prime) plus a fixed margin and is adjusted periodically. Fixed rates remain constant over the life of the loan, providing predictability for the borrower.
A borrower might choose a variable rate loan tied to the Prime Rate + 2.5%, meaning their payment adjusts if the Prime Rate changes. Alternatively, they could secure a fixed-rate loan at 9% for the entire 10-year term, guaranteeing consistent payments.
