SBA loan basics
Short answer
SBA 7(a) loan interest rates are typically variable, though some lenders may offer fixed-rate options for smaller loan amounts or specific products.
The SBA sets maximum allowable interest rates for variable rate loans, which are tied to a base rate like the Wall Street Journal Prime Rate plus a permitted spread. Fixed rates, if offered, are less common and often have their own structure based on market conditions.
A $750,000 SBA 7(a) loan might have an interest rate set at Prime + 2.75%. If the Prime Rate changes, the borrower's interest rate and monthly payment will adjust accordingly.
