What Is a Business Line of Credit and How Does It Work?

Lee Copper July 2, 2026

Running a business needs a regular flow of cash. Monthly earning, profits keep your business going. But with multiple financial obligations, you may sometimes need additional funds. At that time, a business line of credit is considered a useful option. It is different from a loan that provides a lump-sum amount. There is a lot more to know about the line of credit businesses use.

What Is a Business Line of Credit?

A business line of credit is a borrowing option that allows a business to use funds up to an approved limit. The business owner can use the required amount of funds from the available limit. Interest is charged only on the used amount.

When that amount is paid back, the total amount is available again to be used for commercial purposes. It can be secured or unsecured. The secured one needs collateral and has a lower rate. At the same time, the unsecured line of credit does not need any security like property or a vehicle. Hence, its rate of interest can be high.

Example – A business has a limit of £50,000, and it uses £10,000; the remaining credit limit is £40,000. Once the company’s payments are back, the credit limit will be the same, which is £50,000. But the lender will charge the interest only on the used amount of pound 10,000.

How Does a Business Line of Credit Work?

The financial product works through a decided but simple application process.

  • Apply for a credit limit – As per the repayment ability of your business, apply for a credit limit.

  • Approval decision – Receive the approval decision and get approved for a credit limit.
  • Receive and use funds – After approval, use the funds as per the requirement. The rest of the approved withdrawal money is still available to be used.
  • Repay on time – Follow the repayment agreement and pay back. But you pay interest on the used amount only.

Key Features of a Business Line of Credit
