Calculate SBA loan payments, total interest, and eligibility requirements. Compare SBA 7(a) and SBA 504 loans. Free business loan calculator.
SBA loans offer the most favorable terms available to small businesses — lower rates than conventional business loans, longer repayment terms, and lower down payments. But SBA loans come with extensive paperwork and 2-3 month approval timelines. Our calculator shows your monthly payment, total interest cost, and whether your business likely qualifies.
SBA 7(a) loan: most common, up to $5M, working capital or business acquisition, rates prime + 2.25-4.75%, terms up to 25 years. SBA 504 loan: commercial real estate and equipment, up to $5.5M, fixed rate portion, 10-25 year terms. SBA Microloan: up to $50,000 for startups and very small businesses, intermediary lenders, average rate 8-13%. SBA Express: up to $500,000, faster approval (36 hours), higher rates.
Basic SBA loan requirements: For-profit US business. Owner has invested equity in the business. Unable to obtain credit elsewhere on reasonable terms. Size standards: most businesses under 500 employees qualify. Typical lender requirements: 2+ years in business, credit score 650+, debt service coverage ratio of 1.25 or higher (income covers debt payments by 125%). Collateral required for loans over $25,000.
SBA 7(a) rates are variable: prime rate plus a spread. With prime rate at approximately 8.5% in 2026: loans under $25,000: prime + 4.75% = ~13.25%. Loans $25,000-$50,000: prime + 3.75% = ~12.25%. Loans over $50,000: prime + 2.75% = ~11.25%. SBA 504 fixed portion: based on 10-year Treasury, typically 5-7% for the CDC portion.
SBA loan timeline: Document preparation: 2-4 weeks. Lender review: 2-4 weeks. SBA review: 2-4 weeks. Closing and funding: 1-2 weeks. Total: 8-16 weeks typically. SBA Express loans: faster at 2-4 weeks from complete application. Banks are faster than CDFIs for processing. Having all documents ready before applying is critical to minimizing delays.
Difficult but not impossible. Most SBA lenders require 2 years in business. For startups: SBA Microloan program is most accessible (up to $50,000 through nonprofit lenders). Requirements often focus on owner's personal credit and industry experience rather than business history. Strong business plan and industry expertise help significantly. SBA Community Advantage loans through CDFIs serve underserved entrepreneurs including startups.
