The Small Business Administration guarantees a portion of loans issued by approved lenders, reducing lender risk and enabling longer terms and lower down payments than conventional financing. The SBA itself does not lend money. Instead, banks and credit unions extend the funds, and the SBA backs 50 to 90 percent of the loan depending on size and program. This structure allows small businesses to secure capital they might not qualify for through traditional underwriting alone.
The most common program, the SBA 7(a) loan, covers amounts up to $5 million and can be used for commercial real estate purchases, equipment acquisition, debt refinancing, or general working capital. Repayment terms vary: real estate loans may amortize over 25 years, equipment over the useful life of the asset, and working capital over ten years. Because the SBA sets maximum interest rates and fee caps, borrowers gain a measure of cost transparency that proprietary bank products rarely provide.
