SBA 7(a) Q&A
Short answer
Your SBA 7(a) loan interest rate is determined by a base rate (Prime or optional peg rate) plus a lender's spread, influenced by loan size, risk, and term.
SBA sets maximum interest rates, which are typically based on the Prime Rate or the SBA optional peg rate, plus an allowed spread. The specific spread a lender charges is determined by factors like the loan amount (smaller loans often have higher spreads), the perceived risk of your business, the loan term, and the lender's own pricing policies. Rates can be fixed or variable.
For a $500,000 SBA 7(a) loan with a 10-year term, your lender might offer a variable rate of Prime + 2.75%. If the Prime Rate is 8.50%, your initial interest rate would be 11.25%. A smaller loan or a higher-risk business might receive a larger spread.
