What Is a Business Line of Credit? How It Works and Whether You Need One

By American Business Center | Updated July 2026 | Funding & Loans

A business line of credit is the financial equivalent of a safety net you can also use offensively. You get approved for a credit limit — say $100,000 — and you draw from it as needed, pay interest only on what you use, and as you repay it, that capacity becomes available again. It revolves.

That flexibility is what separates a line of credit from a term loan. A term loan gives you a lump sum for a specific purpose. A line of credit gives you access to capital whenever you need it, for whatever you need it for. For many small businesses, it's the single most useful financial tool they can have — not because they're always using it, but because knowing it's there changes how you run the business.

Quick answer: A business line of credit gives you $10,000-$250,000 in revolving credit you draw as needed and repay. You only pay interest on what you use. Best for managing cash flow gaps and seizing short-term opportunities.

How a business line of credit works

Think of it like a business credit card, but with higher limits, lower rates, and actual cash deposits to your account. Here's the mechanics:

• You're approved for a credit limit — typically $10,000 to $250,000 for small businesses

• You draw funds as needed, via transfer to your bank account or a dedicated card

• Interest accrues only on the outstanding balance, not the full credit limit

• As you make payments, your available credit replenishes — that's the revolving part

• Some lines have a draw period (12-24 months) followed by a repayment period

Example: You have a $100,000 line of credit. You draw $30,000 to cover payroll during a slow month. You're paying interest on $30,000, not $100,000. The following month you repay $15,000. Now you have $85,000 available again.

Types of business lines of credit

Secured vs. unsecured

A secured line is backed by collateral — receivables, inventory, or real estate. You get a higher limit and lower rate in exchange for pledging assets. An unsecured line requires no collateral but typically has lower limits (under $50,000) and higher rates. Most online lenders offer unsecured lines; banks prefer secured.

Revolving vs. non-revolving

Revolving credit replenishes as you repay — the standard line of credit structure. Non-revolving credit is drawn once and repaid, similar to a term loan. When people say line of credit, they almost always mean revolving.

Asset-based lines of credit

Tied specifically to your accounts receivable or inventory. The credit limit fluctuates based on the value of those assets. Common in manufacturing, distribution, and staffing. Higher limits than unsecured lines but require ongoing reporting of asset values.

What a business line of credit costs

Interest rate

Rates range from 8% to 60%+ APR depending on the lender and your credit profile. Bank lines run 8-18%. Online lenders run 20-60%. Some lenders express costs as a factor rate rather than APR — always convert to APR for comparison.

Draw fee

Some lenders charge 1-3% each time you draw from the line. If you're drawing frequently in small amounts, this adds up fast. Ask before you sign.

Maintenance or inactivity fee

Some lenders charge a monthly fee ($20-$50) whether or not you use the line. Others charge if you don't draw within a certain period. Read the fee schedule carefully.

Annual renewal fee

Many bank lines require annual renewal — a credit review and sometimes a fee ($150-$500). If your financials have declined, you may not get renewed at the same limit.

Cost Component	Typical Range	Notes
Interest rate (APR)	8-60%	Lower for banks; higher for online lenders
Draw fee	0-3% per draw	Often waived at banks; common online
Maintenance fee	$0-$50/month	Check for inactivity fees
Annual renewal	$0-$500	Banks typically require annual review
Origination fee	0-2%	One-time at setup

Who qualifies for a business line of credit

For bank lines ($50,000-$250,000)

• 2+ years in business

• Personal credit score of 660-700+

• Annual revenue of $200,000+

• Positive cash flow — no chronic overdrafts

• Some collateral for lines above $100,000

For online lender lines ($10,000-$150,000)

• 6-12 months in business

• Personal credit score of 580+

• Annual revenue of $50,000-$100,000

• No collateral required for most unsecured lines

Reality check: Many online lenders advertise low qualification requirements but approve only their best applicants at advertised rates. If your credit is below 620 or revenue below $100K, expect limited options and high rates.

Business line of credit vs. term loan: which do you need?

Use Case	Better Option	Why
Buying equipment	Term loan	Fixed cost, fixed ROI — structure matches
Managing cash flow gaps	Line of credit	Draw what you need, repay when cash comes in
Funding a specific project	Term loan	Known cost, predictable repayment
Covering payroll seasonality	Line of credit	Flexible draws match variable needs
Business acquisition	Term loan (SBA)	Large one-time amount, long repayment
Building inventory for peak season	Line of credit	Draw as needed, repay after season

How to use a line of credit effectively

Good uses

• Bridging the gap between when you invoice clients and when they pay (net 30/60 terms)

• Buying inventory for a known demand spike before the revenue arrives

• Covering payroll during a predictable slow season you'll recover from

• Seizing an unexpected opportunity — a bulk discount, a distressed competitor, a key hire

Dangerous uses

• Funding ongoing operating losses — a line of credit doesn't fix a broken business model

• Making the line a permanent part of your working capital instead of a bridge

• Drawing the full limit and making minimum payments — interest costs become enormous

• Using it for long-term investments — match funding to the life of the asset

Best practice: Think of your line of credit like a tool you pick up and put down. Draw it for a specific purpose, repay it within 90 days, and let it sit empty most of the time. That discipline keeps costs low and keeps the line available when you really need it.

Frequently asked questions

Does having a line of credit hurt my credit score?

Opening a line causes a small temporary dip from the hard inquiry. Long-term, having available credit you don't fully use helps your credit utilization ratio. Drawing large amounts relative to your limit can lower your score temporarily.

Can I get a line of credit as a new business?

It's difficult but possible. Most lenders want 1-2 years in business. Exceptions: business credit cards (which function similarly), microloans, or revenue-based lines from fintech lenders who look at transaction history rather than years in business.

What's the difference between a business line of credit and a business credit card?

A business credit card is revolving credit with limits typically under $50,000. A line of credit gives you actual cash deposits with higher limits. Credit cards charge higher rates (15-25%) but offer rewards. Lines have lower rates and higher limits. Use cards for everyday purchases; lines for larger cash needs.

How often can I draw from my line of credit?

As often as you want, up to your credit limit. Some lenders process draws instantly; others take 1-2 business days. There's no limit on frequency unless specified in your agreement.

Bottom line

A business line of credit is one of the most flexible and useful financial tools available to small businesses — when used correctly. It gives you the ability to manage cash flow without taking on permanent debt, seize opportunities without waiting for a term loan to close, and sleep better knowing capital is available if something unexpected happens.

The key is getting one before you desperately need it. Lenders are much more willing to approve a line when your business is doing well than when you're in a cash crisis. Apply when your financials look good, even if you don't need it right now.
