SBA loan basics
Short answer
Yes, the SBA imposes maximum interest rate caps that lenders can charge on 7(a) loans, which are tied to the Prime Rate and vary based on the loan amount and repayment term.
The SBA sets maximum allowable interest rates for 7(a) loans to prevent predatory lending. These rates are typically structured as the Wall Street Journal Prime Rate plus a maximum spread (e.g., 2.25% to 4.75%). The specific maximum spread depends on the loan amount and the maturity of the loan. Lenders cannot charge interest above these published maximums.
For a $300,000 SBA 7(a) loan with a 10-year term, the maximum interest rate might be Prime + 2.75%. If the Prime Rate is 8.5%, the lender cannot charge more than 11.25%. A smaller loan, like $75,000, might have a higher maximum spread, such as Prime + 4.25%, reflecting the higher administrative cost relative to the loan size.
Insider move
Lenders must ensure that the interest rate charged to the borrower, including any upfront fees, does not exceed the SBA's maximum allowable rate, as non-compliance can jeopardize the guarantee.
