What Is a Business Line of Credit?
A business line of credit works much like a credit card but with higher limits and typically lower interest rates. It gives your business access to a pool of funds that you can draw from as needed, up to a predetermined maximum amount.
The key feature that sets lines of credit apart from loans: you only pay interest on the amount you actually use, not on the entire credit limit.
I've worked with numerous small business owners who initially sought loans before realizing a line of credit better matched their needs. One retail shop owner came in seeking a $50,000 loan for "general business purposes" but left with a line of credit that saved her thousands in interest since she only needed portions of the funds at different times.
The basic structure includes:
- Credit limit: The maximum amount you can borrow
- Draw period: The time during which you can borrow and repay repeatedly
- Interest rate: Applied only to the amount borrowed
- Minimum payments: Required monthly payments, often interest-only during the draw period
- Renewal options: Many lines of credit can be renewed when the draw period ends
Lines of credit typically range from $10,000 to $250,000 for small businesses, though larger businesses may qualify for lines into the millions. Terms usually include a 6-month to 5-year draw period, during which you can borrow and repay repeatedly.
Why Is a Business Line of Credit Useful?
A business line of credit is useful for several reasons:
- Flexibility: You can draw funds as needed, up to your credit limit
- Interest savings: You only pay interest on the amount you use
- Cash flow management: Helps manage cash flow gaps and unexpected expenses
- Rebuilding credit: Can help rebuild credit if used responsibly
Lines of credit excel at managing cash flow gaps and unexpected expenses. They can be especially useful for businesses that experience seasonal fluctuations in revenue or face unexpected expenses. The flexibility to draw funds as needed and only pay interest on the amount used can be a significant advantage over traditional loans.
How to Qualify for a Business Line of Credit
To qualify for a business line of credit, you typically need:
- 6+ months in business: This demonstrates a track record of operation
- Steady revenue: Consistent revenue is important for lenders to assess your ability to repay
The specific requirements can vary depending on the lender and the line of credit. Generally, lenders look for a history of steady revenue and a track record of operation. Some lenders may require a personal guarantee or collateral, while others may not.
Real-World Applications
The practical uses for lines of credit span virtually every industry:
Retail
A boutique clothing store uses its line of credit to purchase seasonal inventory before peak selling periods, repaying the line as items sell.
Construction
A general contractor draws on their line to purchase materials and pay subcontractors before receiving client progress payments.
Manufacturing
A small manufacturer uses their line to purchase raw materials in bulk when prices are favorable, improving margins.
Professional Services
A marketing agency covers payroll during client payment delays, ensuring team members receive consistent compensation despite irregular client payment schedules.
Technology
A software company funds development sprints before subscription revenue arrives from new features.
One restaurant owner I advised uses his line of credit strategically throughout the year: drawing funds for patio upgrades before summer, for marketing before holiday season, and for renovations during slow winter months—all while maintaining healthy cash reserves.
Costs and Considerations
While lines of credit offer tremendous flexibility, understanding the costs helps you use them effectively:
Interest rates
typically range from 7% to 25%, depending on your qualifications and the lender. Most use variable rates that can change with market conditions.
Fees
may include:
- Origination fees (0-3% of the credit limit)
- Annual maintenance fees ($0-500 per year)
- Draw fees (some lenders charge small fees per transaction)
- Inactivity fees (charged if you don't use the line)
Collateral requirements
vary by lender and product. Some lines require specific business assets as security, while others use blanket liens on business assets or personal guarantees.
Renewal considerations
Most lines need renewal after the initial term. Performance issues like late payments can affect renewal eligibility or terms.
A line of credit with a 12% interest rate costs $100 per month in interest for each $10,000 borrowed. This relatively small cost for short-term access to capital explains why so many businesses maintain lines of credit even when not actively using them.
Conclusion
A business line of credit provides unparalleled financial flexibility for businesses of all sizes and stages. The ability to borrow only what you need, when you need it, makes this financing tool essential for managing cash flow, seizing opportunities, and navigating unexpected challenges.
Unlike loans that fund one-time investments, lines of credit adapt to your changing needs, making them an indispensable part of a sophisticated business financial strategy.
