SBA 7(a) Q&A
Short answer
The maximum interest rate for an SBA 7(a) loan is a variable rate tied to a base rate (e.g., Prime Rate) plus a maximum allowable spread, which varies based on loan size and term.
The SBA establishes maximum allowable interest rates to protect borrowers from predatory lending. These rates are typically floating, adjusting with the base rate, and include a spread that lenders can charge up to a certain cap.
For a $1,000,000 loan with a term over 7 years, the maximum rate might be Prime Rate + 2.75%. If Prime is 8.5%, the maximum interest rate would be 11.25%.
Insider move
Lenders must adhere strictly to SBA's maximum interest rate caps. They document the chosen base rate and spread clearly in the loan authorization and regularly adjust variable rates according to the terms.
