A complete guide to SBA loans, bank term loans, business lines of credit, and alternative lending for American small businesses.
The United States offers one of the world's most comprehensive small business lending ecosystems, combining government-backed SBA programs, traditional bank lending, credit union financing, and a thriving alternative lending sector. Understanding the full range of options is essential for any American small business owner seeking capital.
The SBA 7(a) loan program is the most popular government-backed small business loan in the USA, providing up to $5 million for working capital, equipment, real estate, and business acquisition. The SBA guarantees up to 85% of loans under $150,000 and 75% of larger loans, enabling banks to lend to businesses that might not qualify for conventional financing. Interest rates are capped at prime plus 2.75% for loans over $50,000.
The SBA 504 loan program provides long-term, fixed-rate financing for major fixed assets — particularly real estate and large equipment. With loan amounts up to $5.5 million and terms of 10 to 25 years, the 504 program is ideal for established businesses investing in their physical infrastructure.
A business line of credit provides flexible access to funds up to a predetermined limit, with interest charged only on the amount drawn. Lines of credit are ideal for managing working capital fluctuations, covering seasonal expenses, and funding short-term opportunities. Both secured (backed by business assets) and unsecured lines are available, with unsecured lines typically requiring stronger credit profiles.
CDFIs are mission-driven lenders that provide financing to underserved businesses and communities. They offer more flexible lending criteria than conventional banks, making them valuable for minority-owned businesses, businesses in low-income areas, and startups that don't yet qualify for bank financing. The CDFI Fund, administered by the US Treasury, provides capital and technical assistance to CDFIs nationwide.
The US alternative lending sector has grown dramatically, with platforms such as OnDeck, Kabbage (now part of American Express), Fundbox, and BlueVine offering fast, flexible business financing. These lenders use technology and alternative data to make faster credit decisions, often approving loans within 24 hours. While interest rates are higher than bank loans, the speed and flexibility can be valuable for businesses with urgent financing needs.
Invoice financing — including factoring and invoice discounting — enables businesses to access cash against outstanding receivables. This is particularly valuable for B2B businesses with strong customers but slow-paying accounts. Platforms such as Fundbox, BlueVine, and traditional factoring companies provide invoice financing to US small businesses, with advances typically covering 80–90% of invoice value.
