SBA 7(a) Q&A
Short answer
Variable interest rates for SBA 7(a) loans are typically tied to a base rate (like the Prime Rate) plus a fixed spread determined by the lender and capped by the SBA.
The SBA sets maximum allowable interest rates for 7(a) loans, which are expressed as a base rate plus a spread (also known as the "add-on" or "margin"). Common base rates include the Wall Street Journal Prime Rate, Term SOFR, or the SBA Peg Rate. The lender determines the spread, which varies based on loan size and risk, but it cannot exceed SBA-mandated caps. These rates adjust periodically based on the chosen base rate.
An SBA 7(a) loan is approved with an interest rate of Prime + 2.75%. If the Prime Rate is 8.50%, the initial interest rate would be 11.25%. If the Prime Rate later drops to 8.00%, the loan's interest rate would adjust to 10.75%.
