Two of the most common ways to finance a small business are an SBA loan and a business line of credit. Both provide capital. Both require creditworthiness. But they are built for entirely different situations, and choosing the wrong one can cost you time, money, and momentum.
This guide breaks down exactly how each works, what they cost, who qualifies, and which one makes more sense depending on where your business is right now.
What Is an SBA Loan?
SBA loans are term loans partially guaranteed by the U.S. Small Business Administration. The SBA does not lend money directly: it guarantees a portion of the loan (typically 75 to 85 percent), which reduces risk for the lender and allows them to offer better rates and longer repayment terms than conventional business loans.
The most common SBA programs are:
- SBA 7(a): The flagship program, covering loans up to $5 million for working capital, equipment, real estate, and debt refinancing
- SBA 504: Designed for major fixed assets like commercial real estate and heavy equipment; requires a Certified Development Company as a partner lender
- SBA Microloan: Loans up to $50,000 for startups and small businesses through nonprofit intermediaries
SBA loans come with fixed or variable rates tied to the prime rate plus a spread. As of 2026, SBA 7(a) rates generally range from 10.5 to 13 percent depending on loan size, term, and lender. Repayment terms run from 7 to 25 years depending on the use of funds.
What Is a Business Line of Credit?
A business line of credit is a revolving credit facility. The lender approves a maximum limit, and you draw from it as needed, repay it, and draw again. You only pay interest on what you use, not the full limit.
Lines of credit come in two types:
- Secured: Backed by business assets (receivables, inventory, equipment). Lower rates, higher limits, but your assets are at risk if you default
- Unsecured: No collateral required, but typically lower limits and higher interest rates. Lenders rely heavily on credit score and cash flow
Interest rates on business lines of credit vary widely: prime + 1.75 percent for strong borrowers at major banks, up to 30 to 60 percent APR at online lenders for newer or lower-credit businesses. The gap in cost between a bank line and an online fintech line is significant and worth shopping carefully.
The Key Differences Side by Side
Purpose
SBA loans are best for defined, one-time capital needs: buying equipment, acquiring real estate, refinancing existing debt, or funding a major expansion. The funds are disbursed in a lump sum and repaid over a fixed term.
Lines of credit are designed for ongoing, variable needs: covering payroll during a slow month, bridging a gap between invoice and payment, managing seasonal inventory swings. You use it when you need it and pay it back when cash comes in.
Qualification Requirements
SBA loans are thorough. Expect to provide 2 to 3 years of business tax returns, personal tax returns, a business plan, financial projections, a personal financial statement, and collateral documentation. The process typically takes 30 to 90 days. Most SBA 7(a) lenders want a personal credit score of 680 or above, at least 2 years in business, and annual revenue that supports the debt service.
Business lines of credit vary by lender. Bank lines typically require similar documentation to an SBA loan, though with less scrutiny on projections. Online lenders like Bluevine and Fundbox move faster (sometimes same-day approval) but with higher rates and smaller limits, and they often require only 6 to 12 months in business with $100K to $250K in annual revenue.
Cost Over Time
SBA loans cost less over the life of the financing if you need a large lump sum. The combination of a capped rate spread, long repayment term, and partial government guarantee means monthly payments are often lower than you would expect on a $500K loan.
Lines of credit cost less if you only need short-term access to capital and pay it back quickly. The math flips if you carry a balance on a line at 20 percent or above: that is expensive debt. A line of credit is a tool for temporary cash flow gaps, not permanent capital.
Which One Is Right for Your Stage?
The clear winner depends entirely on what you need the money for. Here is a practical breakdown by stage:
Early Stage (Under 2 Years, Under $250K Revenue)
You likely do not qualify for an SBA 7(a) loan yet. Most SBA lenders require 2 years in business and demonstrated cash flow. Your best options at this stage are SBA Microloans (up to $50K through nonprofits with more flexible standards), online business lines of credit from Bluevine or Fundbox, or building your business credit profile through vendor accounts and business credit cards. For the full framework on building credit at this stage, see our guide on building business credit from zero.
Growth Stage (2 to 5 Years, $500K+ Revenue)
This is the sweet spot for both products. If you have a specific capital need (equipment, acquisition, real estate, major expansion), pursue an SBA 7(a) loan: the rates and terms are hard to beat. If your primary challenge is cash flow variability or working capital gaps, a business line of credit from a community bank or credit union offers flexibility at a reasonable cost. Having both is not unusual: an SBA term loan for growth initiatives and a line of credit for day-to-day liquidity management.
Established Stage (5+ Years, $1M+ Revenue)
At this stage, you have more options. Conventional bank loans may be cheaper than SBA in some cases (no guarantee fee). SBA 504 becomes relevant if you are buying commercial real estate. A revolving line of credit at prime + 1 to 2 percent from a major bank is a standard treasury tool at this revenue level.
What About Personal Guarantees?
Both SBA loans and business lines of credit typically require a personal guarantee from anyone owning 20 percent or more of the business. This means your personal credit and personal assets are on the line if the business defaults. Separating your personal and business credit before you borrow protects your personal credit profile from business debt inquiries and defaults. See our guide on how to separate your personal and business credit for the full setup sequence.
If you already have a personal guarantee on a business loan and are struggling, it is worth knowing that some lenders will negotiate the terms of a guarantee. The process is not simple, but it is possible in hardship situations.
Where to Apply
For SBA loans, the SBA’s official lender match tool connects you with approved SBA lenders in your area. Community banks and credit unions often offer better service and more flexible underwriting than large national banks for SBA loans. For business lines of credit, start with your existing business bank, then compare offers from credit unions and online lenders like Bluevine, OnDeck, or Fundbox.
The SBA SCORE program offers free mentoring from retired business executives who can help you review loan applications, assess your financing options, and prepare your documentation. It is one of the most underused free resources available to small business owners.
Whatever route you choose, understand the total cost of the financing before you sign. Compare APR, not just interest rate. Factor in origination fees, guarantee fees (for SBA), and any prepayment penalties. The cheapest-looking option at first glance is not always the cheapest option when you run the full numbers. If you are carrying existing high-interest business debt and considering refinancing, see how to prioritize which debts to pay first.
