SBA loans offer the lowest interest rates available to small businesses. For a company that qualifies, has the documentation ready, and can wait 60–120 days, an SBA 7(a) or 504 loan — administered through the U.S. Small Business Administration — is often the optimal choice. There's no debate about the rate advantage.
But rate is only one component of cost. The total cost of capital includes the opportunity cost of delay, the administrative burden of preparing a full underwriting package, the guarantee fees charged by the SBA (up to 3.75% for loans over $1M), and the risk of denial after investing months of effort. For a business that needs capital in 14 days to secure a purchase order or cover a payroll gap, an SBA timeline can turn a low-rate loan into a missed-opportunity loan.
Non-bank capital — lines of credit, asset-based facilities, revenue-based financing, or term loans — typically costs more in interest but delivers capital 5–10x faster. For many operators, paying a 15% rate on a $200K facility that arrives in 10 days produces better business outcomes than paying 10% on the same facility that arrives in 90 days.
