SBA loan basics
Short answer
The SBA guaranty primarily benefits the lender by reducing their risk of financial loss if a borrower defaults on the loan. This encourages them to lend to small businesses that might otherwise be considered too risky for conventional financing.
By guaranteeing a percentage of the loan (e.g., 75% or 85%), the SBA essentially shares the risk with the lender. If a borrower defaults, the lender can submit a claim to the SBA to recover the guaranteed portion of the outstanding balance, mitigating their potential losses.
A bank makes a $1,000,000 SBA 7(a) loan with an 80% guarantee. If the borrower defaults, and the bank is only able to recover $100,000 from selling collateral, the SBA would pay the bank 80% of the remaining $900,000 loss ($720,000), significantly reducing the bank's exposure.
