A business line of credit is one of the most flexible financing tools available to small business owners — but many entrepreneurs don’t fully understand how it works or when to use it. Unlike a term loan that delivers a lump sum, a line of credit gives you on-demand access to capital up to a set limit. You draw what you need, repay it, and draw again. This guide covers everything you need to know, from the mechanics to how to qualify and where to get the best terms.
What Is a Business Line of Credit?
A business line of credit is a revolving credit facility that functions similarly to a business credit card — but typically with much higher limits, lower rates, and the ability to draw actual cash rather than just card charges. The lender approves a maximum credit limit (say, $75,000). You can draw any amount up to that limit at any time, repay it, and borrow again throughout the draw period.
Key characteristics:
- Credit limit: The maximum amount you can have outstanding at any time
- Draw period: The window during which you can borrow and repay funds (often 12–24 months, then renewed)
- Interest: You only pay interest on what you actually draw, not the full credit limit
- Flexibility: Draw and repay as needed without reapplying for new financing
Revolving vs. Non-Revolving Lines of Credit
Revolving Line of Credit
The most common type. As you repay the drawn balance, your available credit is restored — similar to how a credit card works. If you have a $75,000 limit and draw $40,000, you have $35,000 remaining. When you repay the $40,000, your full $75,000 becomes available again. You can continue this cycle throughout the draw period.
Best for: Ongoing, recurring cash flow needs — covering payroll gaps, managing seasonal swings, buying inventory on short notice.
Non-Revolving Line of Credit
Less common, but worth knowing. With a non-revolving line, repayments don’t restore your available credit. Once you draw and repay $40,000 on a $75,000 non-revolving line, you have only $35,000 remaining for future draws — total draws are capped at the original limit regardless of repayments.
Best for: Specific, one-time projects where you need flexible draw-down timing but don’t anticipate needing to re-use repaid funds.
How Business Line of Credit Interest Works
Unlike a term loan where you pay interest on the full principal from day one, a line of credit charges interest only on your outstanding balance. This can make it significantly cheaper than a term loan for businesses with variable or seasonal needs.
Example: You have a $75,000 line of credit at 12% annual rate. You draw $30,000 in January to cover slow-season costs, then repay it by March.
- Interest charged: $30,000 × 12% × (2/12) = $600 total
- If you’d taken a $30,000 term loan at the same rate for 2 years, you’d pay approximately $4,000 in interest over the life of the loan
The line of credit wins decisively for short-term, variable needs. The term loan wins for capital that will be outstanding for years.
What Can You Use a Business Line of Credit For?
| Use Case | Line of Credit? | Better Alternative? |
|---|---|---|
| Cover payroll during a slow month | Excellent fit | — |
| Purchase seasonal inventory | Excellent fit | — |
| Bridge a gap between invoices and payment | Excellent fit | Invoice factoring (for large receivables) |
| Emergency repairs or unexpected expenses | Good fit | — |
| Fund a major equipment purchase | Possible but not ideal | Equipment loan or SBA term loan |
| Business acquisition or expansion | Not recommended | SBA 7(a) term loan |
| Commercial real estate | Not appropriate | SBA 7(a) Real Estate or CDC/504 |
Business Line of Credit Rates: What to Expect
Interest rates on business lines of credit vary based on lender type, your credit profile, and market conditions. Here’s a realistic overview:
| Lender Type | Typical Rate Range | Credit Limit | Requirements |
|---|---|---|---|
| Traditional Bank | 7%–12% | $25K–$500K+ | 700+ credit, 3+ years, collateral often required |

SmartBiz Business Line of Credit: Key Details
SmartBiz Bank offers business lines of credit with some distinctive features that make them worth considering for newer businesses in particular:
- Credit limit: $50,000 to $100,000
- Time in business required: Just 6 months — significantly lower than most traditional lenders that require 2–3 years
- Draw period: 24-month revolving draw period
- Minimum credit score: 660+
- U.S.-based business in an eligible industry
- No open tax liens or recent bankruptcies
The 6-month business requirement is particularly notable. Most bank-level lines of credit require 2–3 years of operating history. If your business is growing and you have decent credit, SmartBiz’s line of credit can provide meaningful working capital access much earlier in your business lifecycle than most traditional options.

Key Qualification Factors
1. Credit Score
Your personal credit score is heavily weighted. Traditional banks typically want 700+, while some online lenders will work with scores as low as 550–600 (at higher rates). For the best terms, aim for 660+.
2. Time in Business
Most traditional lenders want 2+ years of operating history. SmartBiz offers lines to businesses with just 6 months of operation, which is rare for bank-level credit limits. Online fintech lenders may also accept 6–12 months.
3. Annual Revenue
Lenders want to see revenue sufficient to support the credit facility. Typical minimums range from $100,000 to $250,000+ in annual revenue. Your credit limit is usually tied to a percentage of monthly revenue.
4. Business Cash Flow
Lenders review bank statements to verify consistent cash flow. Even with strong revenue, highly irregular cash flow patterns can raise concerns.
5. Existing Debt Load
Your total debt service (all loan payments) as a percentage of operating income matters. Lenders look for debt service coverage ratio (DSCR) of 1.25x or higher — meaning you earn $1.25 for every $1.00 of debt payment.
6. Industry
Some industries are considered higher-risk and may face stricter requirements or higher rates — including gambling, firearms, cannabis, and certain financial services. Most mainstream businesses qualify.
Documents Typically Required
- Business and personal tax returns (1–2 years)
- 3–6 months of business bank statements
- Business profit & loss statement
- Government-issued ID
- Business license or formation documents
Secured vs. Unsecured Lines of Credit
Secured Lines of Credit
Backed by collateral — often accounts receivable, inventory, real estate, or equipment. Because the lender has an asset to fall back on, secured lines typically offer higher limits and lower rates. A blanket lien on business assets is common.
Unsecured Lines of Credit
Based purely on creditworthiness without specific collateral pledged. These are more flexible but typically carry higher rates and lower limits, especially from traditional lenders. Many online lines of credit are technically unsecured (though a personal guarantee is almost always required).
Note: A personal guarantee is not the same as collateral. A personal guarantee means you personally are liable for repayment if the business defaults, but no specific asset is pledged upfront.
Business Line of Credit vs. Business Credit Card
Both provide revolving access to capital, but there are meaningful differences:
| Feature | Business Line of Credit | Business Credit Card |
|---|---|---|
| Typical Limits | $10K–$500K+ | $1K–$50K typically |
| Interest Rate | 7%–30%+ | 18%–29% (most carry balances) |
| Cash Access | Yes — direct bank transfer | Cash advances are expensive (25%+ APR + fees) |
| Grace Period | Usually no interest-free period | Up to 30 days if paid in full |
| Rewards | Rare | Cash back, points, travel rewards |
| Best For | Larger working capital needs, payroll, inventory | Day-to-day expenses, smaller purchases, rewards |
For most small businesses, a business credit card and a business line of credit serve complementary purposes. Use the card for day-to-day vendor payments and travel (capturing rewards while paying in full each month), and keep the line of credit for larger capital needs.
Tips for Managing a Business Line of Credit Wisely
- Don’t treat it as permanent capital. A line of credit is designed for short-term needs. If you find yourself continuously maxed out and unable to repay, you likely need a term loan instead.
- Draw only what you need. Interest accrues on the outstanding balance — there’s no reason to draw the full limit if you only need half.
- Repay quickly when cash flow allows. The faster you repay, the less interest you pay and the more available credit you have for the next need.
- Don’t use it as an MCA replacement. If you’re struggling to repay the line, a term loan with a longer repayment schedule may be a better structural fit.
- Review at renewal. Lines of credit typically require renewal every 12–24 months. Lenders reassess your financials, so maintaining good payment history and financial health matters for continued access.
The Bottom Line
A business line of credit is the right tool for flexible, recurring working capital needs — seasonal inventory, payroll gaps, unexpected expenses, or bridging receivables. For longer-term capital needs like equipment, real estate, or business acquisition, a term loan is typically more appropriate.
The key advantage SmartBiz offers here is accessibility: with just 6 months in business required and credit limits up to $100,000, it’s one of the few bank-level options available to businesses that haven’t yet built a multi-year operating history.
