A business line of credit (BLOC) is one of the most flexible financing tools available to entrepreneurs. Unlike a traditional business loan that provides a lump sum upfront, a line of credit gives you access to a pool of funds you can draw from as needed—paying interest only on the amount used.

In today’s competitive U.S. business landscape, maintaining healthy cash flow is crucial. Whether you’re covering seasonal dips in revenue, purchasing inventory, or managing unexpected expenses, a business line of credit offers adaptability that other forms of financing may not.

This guide will walk you through everything you need to know—from the types of BLOCs to interest rates, qualification requirements, application steps, and best practices.

What Is a Business Line of Credit?

A business line of credit works similarly to a credit card but typically offers higher limits and lower interest rates.

How It Works:

1. Approval & Credit Limit—You’re approved for a maximum borrowing amount (e.g., $50,000).

2. Draw Funds as Needed – You can withdraw any amount up to your limit.

3. Pay Interest Only on What You Use—If you draw $10,000, you only pay interest on that $10,000.

4. Replenishment—As you repay, the available credit is restored.

Common Uses:

• Seasonal working capital

• Payroll during low-revenue months

• Buying discounted bulk inventory

• Covering emergencies like equipment repair

Types of Business Lines of Credit

Not all BLOCs are the same. The right choice depends on your business’s size, stability, and collateral availability.

Interest Rates & Fees

As of August 2025, average APRs for business lines of credit in the U.S. range from 7% to 25%, depending on:

• Credit score (higher scores get lower rates)

• Annual revenue

• Time in business

• Collateral offered

Common Fees to Watch For:

• Draw fees (e.g., 1–3% of each withdrawal)

• Maintenance fees (monthly or annually)

• Inactivity fees (if you don’t use the line for a set period)

Pro Tip: Ask lenders if they use the average daily balance method for interest—this can reduce total costs if you pay down quickly.

How to Qualify for a Business Line of Credit

While requirements vary by lender, here are typical U.S. standards:

• Credit score: 600+ for most online lenders, 680+ for banks

• Time in business: At least 6–12 months (banks often require 2+ years)

• Annual revenue: $50,000–$100,000 minimum

• Documentation: Tax returns, bank statements, profit & loss statements

Tips to Improve Approval Odds:

1. Build both personal and business credit before applying.

2. Keep your debt-to-income ratio low.

3. Show consistent revenue in bank statements.

Step-by-Step: How to Apply

1. Check Your Credit Reports—Ensure no errors are lowering your score.

2. Gather Financial Documents—Last 2 years of tax returns, bank statements, and P&L.

3. Compare Lenders—Banks, credit unions, online lenders, SBA-backed.

4. Submit Application—Either online or in person.

5. Review Offer & Terms—Look at APR, fees, and repayment flexibility.

6. Sign Agreement & Access Funds—Often via transfer to your business checking account.

FAQs

Q: Can I get a BLOC with bad credit?
Yes—online lenders may help, but expect higher APRs and possibly require collateral or personal guarantees.

Q: How quickly can I access funds?
Online lenders like Fundbox can provide funding in 1–3 business days; bank lines (e.g., Wells Fargo) may take up to 2 weeks for larger/request-specific products.

Q: What’s the difference between APR and simple interest or fee structures?
APR annualizes total cost and is easier to compare; some lenders use simple or weekly fees that may understate effective cost—always ask for equivalent APR.

Conclusion

A business line of credit is a powerful financial tool for maintaining stability and fueling growth. When used strategically, it can help you seize opportunities, navigate slow seasons, and safeguard your business against surprises.
