What Is a Business Line of Credit? How It Works and When It Fits
✦ Key takeaways
- A business line of credit is a revolving credit limit you draw from up to a maximum, paying interest only on what you use.
- It differs from a loan in two ways: you take money in installments as needed, and the limit replenishes as you repay.
- It is ideal for covering seasonal cash-flow gaps, working capital and unexpected expenses.
- It may be secured by an asset or unsecured, and its interest rate is usually variable.
What is a business line of credit?
A business line of credit is a "revolving" financing facility where a bank or lender grants you a maximum borrowing limit — say $50,000 — that you draw from as you wish, whenever you wish, up to that ceiling. The core advantage is that you pay interest only on the amount actually drawn, not on the whole limit. Each time you repay part of it, that amount becomes available to draw again — much like a credit card but for business and usually at lower cost.
This makes it a flexible liquidity tool: you open it today, leave it unused at little to no cost, and draw only when you need to.

How it differs from a traditional loan
A term loan gives you a lump sum at once that you repay in fixed installments, paying interest on the whole amount from day one. A line of credit gives you the flexibility to draw in installments and reuse:
| Criterion | Line of credit | Term loan |
|---|---|---|
| Disbursement | Draws as needed | One lump sum |
| Interest | On drawn amount only | On the full amount |
| Renewal | Replenishes after repayment | Ends when repaid |
| Best for | Variable cash flow, recurring costs | A large, fixed-cost project |
Types: secured and unsecured
A secured line requires collateral such as a business asset, inventory or receivables, and usually grants a higher limit and lower rate. An unsecured line requires no collateral but relies on your credit strength and business performance, typically with a lower limit and higher rate. Your choice depends on the assets you hold and the risk you accept.
When to use it
A line of credit shines in temporary liquidity situations: covering payroll in a slow month, buying inventory before peak season, bridging the gap between issuing an invoice and collecting it, or handling a sudden equipment breakdown. The practical rule: use it for short-term expenses that will be repaid quickly from revenue, not to fund chronic losses or long-term assets.
Costs and fees to watch
Beyond interest (often variable and tied to an index), you may find an origination fee, an annual fee, a draw fee per transaction, and sometimes a "non-use" fee on the undrawn portion. Add these up to know the true cost, and compare lenders. Note that late payment harms your business credit and raises your future cost.
How to qualify
Lenders usually look at: how long your business has operated (many require at least a year), your annual revenue, your personal and business credit scores, and your bank statements. Preparing tidy financial statements and a clear cash-flow statement raises your odds and improves your terms.
Bottom line
A business line of credit is a "liquidity cushion" that gives your business the flexibility to weather fluctuations without selling assets or borrowing a large sum at once. Use it with discipline for short-term expenses, understand its full costs, and repay regularly — and it becomes a growth tool rather than a burden.
