SBA loan basics
Short answer
A personal guarantee is a promise by the business owner to repay the loan personally if the business cannot. It is required to show the owner's commitment and hold them accountable for the loan's repayment.
The SBA requires personal guarantees from all owners with 20% or more equity to ensure maximum effort and responsibility from the principals. This aligns the owner's personal financial health with that of the business, encouraging prudent management.
If John owns 50% of a business that gets an SBA loan, he signs a personal guarantee. If the business defaults, John is personally responsible for repaying the loan, meaning his personal assets could be at risk.
Insider move
Lenders use personal guarantees to increase their security and ensure borrower commitment. They will assess the personal financial statements of guarantors to determine their ability to repay if the business defaults.
