Business Lines of Credit: How They Work, What They Cost, and How to Get One

A revolving line of credit gives your business flexible, reusable capital at 7-20% APR. You draw what you need, pay it back, and draw again — without reapplying every time. Here's how it actually works, what it costs, and whether it's the right tool for your business.

Maria runs a 40-seat restaurant in the hospitality industry. This spring, she needs $30,000 to replace aging kitchen equipment. But she also knows summer is coming — and she'll need about $15,000 for seasonal inventory. Then in August, a marketing agency pitches a $8,000 campaign that could fill the off-season gaps.

She could apply for three separate working capital loans. Three applications. Three approval processes. Three fixed repayment schedules. Or she could set up a single business line of credit for $75,000, draw from it when each need arises, and only pay interest on whatever amount she's actually using.

That's the core value of a business line of credit: one approval, multiple uses, and the flexibility to match your funding to your actual cash flow needs.

How a Business Line of Credit Works

A business line of credit is revolving capital. You get approved for a maximum amount — say, $100,000 — and can draw from it whenever you need to. When you repay what you've drawn, that amount becomes available again. No reapplication, no new approval process.

1. You get approved for a credit limit. Based on your revenue, credit score, and time in business, a lender sets your maximum. Typically $10K-$250K.

2. You draw what you need. Need $20,000 for inventory? Draw $20,000. The other $80,000 stays available but costs you nothing. Most draws land in your account within 1-2 business days.

3. You pay interest only on what you use. At 12% APR on that $20,000 draw, you're paying roughly $200/month in interest — not $1,000/month as if you'd borrowed the full $100K.

4. You repay and your limit resets. Pay back that $20,000 and your full $100,000 limit is available again. Need $35,000 next month? Draw it. The cycle continues.

This revolving structure is what separates a line of credit from a term loan. With a term loan, you receive a lump sum, repay it on a fixed schedule, and that's it.

What a Business Line of Credit Actually Costs

Business lines of credit carry an APR of 7-20%. Where you land depends on your credit profile, revenue, and time in business.

That last row is the key advantage. An unused line of credit costs you nothing. It sits there as a financial safety net — available when you need it, invisible when you don't.

Line of Credit vs. Term Loan vs. Business Credit Card

A line of credit wins when:

• You have ongoing, variable funding needs (not a one-time purchase)
• You want access to capital without paying for it until you use it
• You need more than a credit card can offer but don't want a fixed loan
• Cash flow is seasonal or unpredictable

A term loan is better when:

• You need a large one-time amount ($100K+ for equipment, expansion, etc.)
• You know the exact amount and prefer predictable monthly payments
• You qualify for a lower rate through an SBA loan

Who Qualifies for a Business Line of Credit

Lines of credit have moderate qualification requirements. They're easier to get than SBA loans but more selective than revenue-based funding.

• Annual Revenue: $100K minimum. Higher revenue unlocks larger credit limits and better rates.
• Time in Business: 1 year minimum. Lenders want to see consistent revenue history.
• Credit Score: 600+ for most options. 700+ for the best rates (7-12% APR).
• Collateral: Business assets, personal guarantee, or cash flow. Most lines over $50K require some form of security.

Common Reasons for Denial

• Revenue below $100K/year — Lenders need proof you can repay draws consistently
• Less than 1 year in business — Startups typically need revenue-based funding instead
• Frequent overdrafts or NSF fees — Red flag for cash flow management
• Active tax liens — Most lenders won't extend revolving credit with unresolved tax debt
• Declining revenue trend — Lenders want to see stable or growing income

5 Smart Ways to Use a Business Line of Credit

1. Seasonal Inventory Purchases. A restaurant that triples its seafood order every summer, or a retail shop stocking up before the holidays. Draw $30K for inventory in October, sell through December, repay by January. Total interest cost at 12% APR: roughly $300 for a 3-month draw.

2. Bridging Accounts Receivable Gaps. Professional services firms and contractors often wait 30-90 days for client payments. A line of credit covers payroll and operating costs during those gaps without the fees of invoice factoring.

3. Emergency Repairs. An HVAC system dies in July. Home services companies know: if the truck breaks down, revenue stops. A line of credit means the $8,000 repair doesn't shut down operations.

4. Opportunity Fund. A supplier offers a 15% discount on bulk materials, but only for 48 hours. Or a competitor closes and their prime location becomes available. A line of credit lets you move fast.

5. Payroll Bridge. When a big contract payment is coming but payroll is due Friday, a short-term draw covers the gap. Draw $15K on Monday, deposit the client check on Thursday, repay immediately. Interest cost: less than $10.

State Spotlight: Business Lines of Credit Across the U.S.

Lines of credit are available nationwide, but local market conditions shape how businesses use them. In university-anchored economies like Morgantown, West Virginia, businesses face pronounced seasonal swings. When 30,000 WVU students leave for summer, restaurants, retail shops, and service providers see revenue drop significantly. A revolving line of credit lets these businesses stock up before fall semester, cover lean summer months, and invest in back-to-school marketing — all from one approved facility.

Similar patterns play out in college towns and seasonal markets across West Virginia and beyond. Whether you're managing seasonal tourism in a coastal Texas town or handling contract payment cycles in California, revolving credit adapts to your local market rhythm.
