When you get an SBA loan, your loan amount will be partially determined by the type of SBA loan you choose. For example, SBA 504 loans have the highest loan maximums ($20 million) while SBA Microloans are much smaller ($50,000 max.). One of the most popular types, SBA 7(a) loans, max out at $5 million. Your loan maximum will also be determined by your business revenue and your ability to repay the loan. (And as a reminder, you’re not really borrowing from the SBA―it’s just guaranteeing the loan you get from a lender.)
