SBA loan basics
Short answer
The SBA 'guarantee' means the SBA promises to repay a portion of the loan principal to the lender if the borrower defaults. It does not protect the borrower from repayment obligations or personal liability.
The SBA's guarantee percentage varies (e.g., 75-85% for most loans). This guarantee is provided to the lender, reducing their risk and encouraging them to make loans they might otherwise consider too risky. The borrower remains 100% responsible for repaying the loan, typically backed by a personal guarantee from owners.
A bank makes a $1,000,000 SBA 7(a) loan with an 80% SBA guarantee. If the business defaults and the bank can only recover $200,000 from selling collateral, the SBA would pay the bank 80% of the remaining $800,000 ($640,000). The borrower, however, is still liable for the full $800,000 shortfall.
Insider move
Lenders rely on the guarantee as a safety net but must still exercise prudent lending practices and adhere to all SBA servicing requirements to ensure the guarantee remains valid in case of default.
