SBA loan basics
Short answer
A fixed interest rate stays the same throughout the loan term, providing predictable payments, while a variable rate changes periodically, usually with a benchmark like the Prime Rate, making payments less predictable.
While most SBA 7(a) loans are variable, a few may offer a fixed rate option for certain terms, typically shorter ones. The variable rate adjusts based on market conditions, directly impacting the borrower's monthly payments.
If a borrower has a fixed rate of 10% on a $200,000 loan, their monthly payment for principal and interest remains constant. If they have a variable rate tied to Prime + 3%, their payment will fluctuate as the Prime Rate changes.
