SBA 7(a) Q&A
Short answer
The primary difference is that a fixed rate remains constant throughout the loan term, providing predictable payments, while a variable rate fluctuates with a base rate, causing payments to change.
SBA 7(a) loans can be structured with either fixed or variable interest rates. A fixed rate offers stability, as your monthly principal and interest payments remain the same. A variable rate, tied to an index like the Prime Rate or Term SOFR, adjusts periodically (e.g., quarterly or semi-annually), meaning your payment amounts can increase or decrease over time.
If you choose a fixed rate of 7.00% on a $500,000 loan, your payment will be constant. If you choose a variable rate of Prime + 2.00% (e.g., 6.50% + 2.00% = 8.50% initially), your payment will change as the Prime Rate fluctuates.
