A business line of credit vs a business overdraft


When it comes to external funding, choosing the right option for your business can prove difficult. There are plenty of options on the market that’ll help you with everything from bridging the gap between sending an invoice and getting paid, to funding your expansion and increasing your digital capabilities. In this blog post, we’ll explain how a business line of credit is similar to a business overdraft. Then more importantly, we’ll highlight the 4 main differences.

Key definitions

A business line of credit is a pre-arranged amount of money that you can borrow from in parts or in full. As you repay the funds you use, they will become available for you to borrow once again. This process can repeat for as long as your business line of credit is active.

A business overdraft is attached to your bank account, and it allows you to spend beyond your bank account’s balance if needed. Then, you’ll repay any funds you use.

4 similarities between a business line of credit and a business overdraft

Similarity: You only pay interest on the amount you borrow

Business lines of credit and overdrafts are both flexible in that you only pay interest on the funds you use out of your total agreed limit. This is unlike a business loan for example, because you pay interest on the total amount of a loan no matter how much you use.

Similarity: You can dip in and out of a pre-defined limit

You’re given a pre-determined spending limit with a business line of credit and a business overdraft. As you use some of the funds and pay them back, the funds will then become available to you again. This goes for both options.

Similarity: You may pay a fee to keep the facility active

Some lenders or account providers may charge you a monthly or annual fee to use an overdraft. Similarly, you might have to pay a subscription fee to keep a business line of credit open and available for you to use.

Similarity: They can be terminated if you don’t make your repayments

As with any type of credit facility, it’s important that you make your repayments on time and in full. Not doing so could negatively affect your credit score and cause your lender to close your business line of credit or overdraft. This could cause any outstanding payments to become immediately due, meaning you’ll have to repay any funds you’ve withdrawn quicker than you may have planned.

4 differences between a business line of credit and a business overdraft

Difference: The type of interest rate usually differs between the two options

Variable interest rates change over time, usually in line with the UK economy and the Bank of England base interest rate (also known as Bank Rate). Your periodic repayments on your overdraft could increase if the interest rate changes.

The interest rate on a business line of credit is usually fixed. That means it should stay the same whilst you’re using it.

Difference: A business line of credit is pre-agreed, an overdraft may not be

If your business bank or account provider hasn’t agreed to give you an overdraft, you may have an unauthorised overdraft attached to your account instead. If you spend from this, you’ll likely have to pay an additional fee. It’s usually the same case if you spend beyond the limit of an overdraft that has been arranged with your bank.

A business line of credit has to be authorised by both you and the lender, once you’ve applied for it. Some lenders, like us, may even pre-approve you for a line of credit so there’s no need for a lengthy application.

Difference: A business line of credit is separate from your bank account, unlike an overdraft

When you try to spend more than what’s in your bank account and the transaction still goes through, it could mean you’ve gone into either an unauthorised or authorised overdraft. You can only go into your overdraft once you’ve used up all the money in your account.

A business line of credit is separate from your bank account and balance. So, it can be used whether you have money in the bank or not.

Difference: One option may be better than the other, depending on your needs

To avoid being charged the extra fees that can come with overdrafts, many small business owners only choose to use them when they’re really in a pinch. This may be to fund a short-term gap in income or to pay off an unexpected expense.

Business lines of credit are useful as part of a wider, long-term funding plan. Whilst they can be used as a buffer whilst you’re waiting for accounts receivable to come in, a business line of credit can also be a good choice to finance your growth plans. Think investing in a new marketing campaign, upgrading equipment or buying inventory in bulk.
