SBA loan basics
Short answer
The SBA guaranty protects the lender by promising to reimburse them for a specified percentage of the loan's outstanding principal balance if the borrower defaults. This significantly reduces the lender's risk exposure.
For a 7(a) loan, the SBA guarantees a portion, typically 75% for loans over $150,000 and 85% for loans up to $150,000, to the lender. If the borrower stops making payments, and after the lender has exhausted reasonable collection efforts, the SBA will purchase the guaranteed portion of the loan from the lender.
A bank issues a $500,000 SBA 7(a) loan with a 75% guaranty ($375,000 guaranteed portion). If the borrower defaults and the outstanding balance is $400,000, the SBA will pay the bank $300,000 (75% of $400,000), reducing the bank's loss.
