SBA loan basics
Short answer
For the bank, the SBA guaranty means that the SBA promises to reimburse the bank for a significant portion (typically 75-85%) of the outstanding loan balance if the borrower defaults.
The guaranty reduces the financial risk for the lending institution. This encourages banks to make loans to small businesses that might otherwise be considered too risky under conventional lending criteria, thereby expanding access to capital for small businesses.
If a bank lends $1 million with an 85% SBA guaranty, and the borrower defaults on $500,000, the SBA would reimburse the bank for $425,000 ($500,000 x 85%), reducing the bank's loss to $75,000.
