SBA loan basics
Short answer
The SBA guaranty significantly reduces the lender's risk of financial loss if a borrower defaults, encouraging them to lend to small businesses that might not otherwise meet their conventional lending criteria.
By guaranteeing a percentage of the loan (up to 75-85% for most 7(a) loans), the SBA makes these loans less risky for banks. This encourages them to extend credit to startups, businesses with limited collateral, or those in underserved markets.
A bank approves a $1,000,000 SBA 7(a) loan with an 85% guaranty. If the borrower defaults and the bank recovers only $100,000 from collateral, the SBA will pay the bank 85% of the $900,000 loss, reducing the bank's exposure.
