Business Line of Credit: How It Works

A line of credit is the most flexible tool in small business funding — money you can tap when you need it and leave untouched when you do not. Here is how it actually works.

Revolving credit, not a lump sum

A business line of credit gives you a set borrowing limit — say $50,000 — that you can draw against at any time. You take what you need, when you need it, and only pay interest on the amount you have actually drawn. As you repay, the available credit replenishes, the same way a credit card works.

That is the key difference from a term loan: a loan hands you the full amount upfront and charges interest on all of it. A line sits ready and costs you little or nothing until you use it.

What it costs

You pay interest on your outstanding balance, often at a variable rate. Some lines carry a small annual or monthly maintenance fee, and some charge a draw fee each time you pull funds. Because you are only charged on what you use, a line can be cheaper than a loan for needs that come and go — but rates run higher than a long-term bank loan, reflecting the flexibility.

When a line of credit is the right tool

Lines shine for recurring or unpredictable needs: covering seasonal dips, smoothing the gap between paying suppliers and getting paid, handling surprise repairs, or stocking up before a busy stretch. If you cannot predict the exact amount or timing, a line beats a lump-sum loan. For a single, known, one-time expense, a term loan or advance is often the better structure.

How to qualify

Lenders look at the same core inputs as other products — time in business, monthly revenue, credit profile, and existing debt. Stronger files unlock larger limits and lower rates. Newer businesses or thinner credit can still qualify for smaller revenue-based lines.
