SBA loan basics
Short answer
Yes, the SBA establishes maximum allowable interest rates that lenders can charge for 7(a) loans, which are tied to a base rate plus a permissible spread, ensuring competitive and fair pricing.
The maximum interest rate is determined by adding a fixed spread (e.g., 2.25% to 4.75% depending on loan size and term) to a chosen base rate, such as the Wall Street Journal Prime Rate, SOFR, or Term SOFR. Lenders cannot exceed these caps. The SBA periodically updates these maximum spreads.
If the Prime Rate is 8.50%, and the maximum spread for a loan of a certain size is 2.75%, the highest interest rate a lender could charge would be 11.25% (8.50% + 2.75%).
