How an SBA loan payment is calculated

SBA 7(a) and 504 loans are fully amortizing — a fixed monthly payment covers interest plus principal until the balance hits zero. Because SBA terms are long (up to 10 years for working capital, 25 years for real estate), the monthly payment is low relative to the amount borrowed, even though the total interest over the life of the loan can be significant.

SBA rates and terms in 2026

Rates

SBA 7(a) rates are variable and tied to the Prime Rate plus a lender spread capped by the SBA. In 2026 that lands most borrowers between 10.5% and 14%. SBA 504 loans, used for real estate and major equipment, carry a fixed, often lower rate on the SBA-backed portion.

Terms

SBA maximum terms: up to 10 years for working capital and equipment, and up to 25 years for commercial real estate. Longer terms lower the monthly payment but raise lifetime interest — the calculator shows both so you can weigh cash flow against total cost.

The trade-off: cheapest money, slowest money

SBA loans offer the lowest rates and longest terms available to small businesses, which is why they're worth pursuing for large, long-horizon needs. The catch is speed: full SBA underwriting commonly takes 30 to 90 days, and documentation is heavy.

The Broker Shop is a funding broker, not a lender. We help you pursue SBA financing and, where speed matters, line up faster alternatives at the same time — all free to you, since the lender pays our fee at closing.
