Business lines of credit are one of the most widely used types of financing when it comes to small businesses. According to findings from the Federal Reserve Banks’ 2024 Small Business Credit Survey, 34% of small businesses surveyed regularly used or carried a balance on lines of credit.

This type of small business financing is a great solution for short-term funding and covering operating expenses. But what is it, and how exactly does it work? We’ll break down everything you need to know about business lines of credit in this guide.

What is a small business line of credit?

A small business line of credit is a flexible financing option for businesses that allows business owners access to a predetermined amount of money that they can draw from as needed. With a line of credit, the owner has access to the money, but doesn’t receive it all in a lump sum upfront. This structure makes a line of credit more similar to a credit card than a traditional term loan.

How a business line of credit works.

When you’re approved for a small business line of credit, your lender gives you access to an amount of money to use for business purposes up to the limit agreed upon. You can then use amounts you need from the line of credit at any time, up to the limit. 

Think of it like an envelope of cash the bank gives you for rainy day expenses. You don’t have to ask the bank for money every time you need it, since you’ve already been approved for that amount. You also don’t have to use all the funds if you don’t need to, giving small businesses more control over expenses, interest, and paying back on the loan.

To use the line of credit, generally you’ll transfer the funds you need into your bank account from the line of credit, or use special checks to draw directly from the line. 

Depending on the type of line of credit you have, the funds you borrow and repay may or may not become available again to borrow up to your limit. Let’s talk about these categories of lines of credit next, so you know the difference.

Revolving vs. non revolving line of credit.

Your line of credit will typically fall into two categories: revolving, or non-revolving. With a revolving line of credit, you can borrow repeatedly up to the credit limit as you repay the balance—similar to a credit card.

A non-revolving line of credit is a fixed limit. Each time you borrow from the line, and repay, that amount is not available for use again. Once you use all of the approved funding up to the limit, the account can’t be reused, and you’ll need to apply for a new loan. This makes a non-revolving line of credit more similar to a traditional loan.

Paying back a line of credit.

Business lines of credit are a short-term funding solution. Most lines of credit will need to be repaid within 1-2 years. Similar to any other loan, you’ll make regular payments on your balance towards the principal, as well as interest charges on the funds you have used.
