SBA loan basics
Short answer
The SBA typically guarantees 75% to 85% of the loan amount to the lender, depending on the loan size and type.
The percentage of the guarantee varies. For most standard 7(a) loans exceeding $150,000, the SBA guarantees 75% of the loan amount. For loans up to $150,000, the guarantee is generally 85%. This guarantee protects the lender, not the borrower, by reducing the lender's exposure to loss in case of default. The borrower remains 100% responsible for repaying the entire loan.
A business takes out a $400,000 SBA 7(a) loan. The SBA would guarantee 75% of this, meaning $300,000 is guaranteed. If the loan defaults and the lender recovers $100,000 from collateral, the remaining $300,000 would be split, with the SBA covering $225,000 (75%) and the lender absorbing $75,000 (25%) of the loss.
Insider move
Lenders manage their risk exposure based on the guaranteed percentage, knowing they are still responsible for the unguaranteed portion. They ensure all SBA rules are followed to preserve the guarantee in case of default.
