SBA loan basics
Short answer
The SBA's 'guarantee' means the SBA promises to reimburse the lender for a percentage of the loan amount if the borrower defaults, reducing the lender's risk.
The SBA guaranty is an assurance to the lender, not the borrower. It makes lenders more willing to provide financing to small businesses that might otherwise be considered too risky. The guaranty percentage typically ranges from 75% to 85% for standard 7(a) loans, meaning the SBA will pay the lender that portion of the outstanding balance if the borrower defaults and the lender follows proper servicing and liquidation procedures.
A bank issues a $500,000 SBA 7(a) loan with a 75% guaranty. If the borrower defaults and the bank recovers $100,000 through collateral liquidation, the remaining $400,000 balance would trigger the SBA guaranty, and the SBA would pay the bank 75% of that $400,000, or $300,000.
