SBA loan basics
Short answer
Yes, the SBA sets maximum interest rates that lenders can charge on 7(a) loans. These maximums are tied to a base rate (such as Prime) plus an allowable spread, which varies based on the loan amount and maturity.
The SBA establishes "maximum allowable" rates to protect small businesses from excessive charges. For loans with maturities of seven years or more, and amounts over $50,000, the maximum spread is generally 2.75% above the base rate.
If the Prime Rate is 8.5%, and a business secures a $200,000, 10-year SBA loan, the lender cannot charge more than 8.5% + 2.75% = 11.25%. A lender could, however, offer a lower rate like Prime + 2.0%.
