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.
Worked example
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.
- If your need is large and not urgent (buying a building, a major expansion), SBA is usually the right call.
- If you need capital in days, a term loan, line of credit, or revenue-based financing fills the gap — sometimes used as a bridge until SBA funds.
