SBA loan basics
Short answer
Banks often prefer offering SBA 7(a) loans because the SBA's guarantee reduces the risk of default for the lender, making it safer to lend to small businesses that might present higher risk or lack sufficient collateral for a conventional loan.
The SBA guarantees a portion of the loan principal, typically 75% to 85% depending on the loan amount. This reduces the potential loss for the lender if the borrower defaults, encouraging banks to extend credit to a wider range of small businesses.
A bank considers two $100,000 loan applications: one conventional, one SBA 7(a). The SBA guarantees 75% of the 7(a) loan. If both businesses default, the bank faces a potential $100,000 loss on the conventional loan, but only $25,000 (plus recovery efforts) on the SBA 7(a) loan because the SBA covers the remaining $75,000.
