SBA 7(a) Q&A
Short answer
For a variable-rate SBA 7(a) loan, the lender adjusts the interest rate periodically (e.g., monthly, quarterly) based on changes to the selected base rate index plus an agreed-upon spread.
SBA 7(a) variable rates are tied to a published base rate (typically Wall Street Journal Prime, LIBOR, or SOFR), plus a fixed spread determined at loan origination. The loan authorization specifies the adjustment frequency. Lenders update the rate in their system based on the current index value.
A borrower has a variable-rate SBA 7(a) loan tied to the WSJ Prime Rate plus 2.75%, adjusted quarterly. If the Prime Rate increases from 7.00% to 7.25% at the next adjustment date, the borrower's new rate will become 10.00% (7.25% + 2.75%).
Insider move
Lenders ensure the interest rate adjustments adhere strictly to the terms outlined in the SBA Loan Authorization and the loan agreement. They track the base rate index and apply the correct spread, communicating any changes to the borrower as required.
