SBA loan basics
Short answer
Variable interest rates are generally more common for SBA 7(a) loans, though fixed-rate options may be available depending on the lender and loan type.
Most SBA 7(a) loans are structured with variable rates tied to a benchmark like the Wall Street Journal Prime Rate plus a lender's spread. While fixed rates are permissible under SBA rules, many lenders prefer variable rates due to market conditions and risk management.
A borrower looking for a 10-year loan will most likely be offered a variable rate based on Prime + 2.75%, rather than a fixed rate for the entire term, unless they find a specific lender offering fixed-rate products.
Insider move
Lenders manage interest rate risk. Variable rates allow them to adjust to market changes. If offering a fixed rate, they must ensure the rate adequately compensates for that risk over the loan term.
