SBA loan basics
Short answer
SBA 7(a) loans typically offer both variable (floating) and fixed interest rate options, with variable rates being more common.
Borrowers generally have the choice between a variable rate, which adjusts periodically (e.g., quarterly or monthly) based on a benchmark like the Prime Rate or SOFR, and a fixed rate, which remains constant throughout the loan term. Variable rates are often preferred by lenders for longer-term loans due to market fluctuations, while fixed rates offer predictability for borrowers.
A business could choose a variable rate set at Prime + 2.5%, meaning their payments would change if the Prime Rate fluctuates. Alternatively, they could opt for a fixed rate of 9.0% for the entire loan term, providing stable monthly payments regardless of market changes.
