SBA loan basics
Short answer
The SBA guarantee means that if the borrower defaults on the loan, the SBA will reimburse the lender for a portion of the outstanding balance, reducing the lender's risk of loss.
The guarantee acts as a risk mitigant for the lender, not as direct collateral. It encourages lenders to extend credit to small businesses they might otherwise consider too risky. The SBA's commitment to purchase a percentage of the loan's outstanding balance upon default helps maintain liquidity and willingness to lend in the small business market.
A bank makes a $1 million SBA 7(a) loan with a 75% guarantee. If the borrower defaults, and after liquidating all collateral, $400,000 remains outstanding, the SBA would purchase 75% of that remaining amount, paying the bank $300,000.
