What Is an SBA Loan?

Understand how SBA-supported financing can help qualifying businesses fund growth, acquisitions and major investments.

An SBA loan is generally issued by an approved lender and supported by a government guaranty. The guaranty can reduce part of the lender's risk, but the borrower remains responsible for repaying the full debt.

Businesses may use qualifying financing for purposes such as working capital, equipment, business acquisition, inventory, owner-occupied real estate, construction or refinancing eligible debt.

Actual terms depend on the program, business purpose, lender underwriting, available cash flow, borrower equity, collateral, credit history and other eligibility factors.

Extra payments are applied toward the outstanding balance in this calculator. They may reduce total interest and shorten the estimated payoff period.
