SBA 7(a) Q&A
Short answer
The primary difference is predictability: a fixed rate offers stable monthly payments, while a variable rate's payments can change based on market interest rate fluctuations.
A fixed-rate SBA loan means the interest rate remains constant for the life of the loan, providing predictable payments. A variable-rate loan, however, adjusts periodically based on a chosen index rate (like Prime) plus a fixed margin, leading to fluctuating payments.
A fixed-rate $500,000 loan at 8.0% will have the same principal and interest payment for 10 years. A variable-rate loan at Prime + 2.75% might start at 8.0% but could rise to 9.0% or drop to 7.0% if the Prime Rate changes, altering your monthly payments.
