What Is A Business Overdraft?


Last Updated: 8 January 2025
Reviewed By: Ian Wright (Managing Director)

A business overdraft is a credit facility attached to a business bank account, allowing the business to withdraw more money than is actually available in the account up to an agreed limit. This means the account can go into a negative balance, offering the business flexibility to manage its cash flow, especially to cover short-term financial needs or unexpected expenses.

Overdrafts are typically used for managing working capital and short-term financing rather than for long-term investments. The interest is usually charged on the overdrawn amount, and there may be additional fees associated with the overdraft facility. The terms, including the overdraft limit and the interest rate, are agreed upon between the bank and the business based on the business’s creditworthiness and financial history.

It’s important for businesses to manage their overdrafts carefully, as excessive reliance on an overdraft can indicate poor financial management and can lead to high interest and fees. Additionally, since overdraft facilities are repayable on demand, banks can request repayment at any time, which could potentially put a strain on the business’s financial resources if not planned for appropriately.

How does a business overdraft work?

Here’s a detailed breakdown of how it typically works:

  1. Application and Approval: A business applies for an overdraft facility with its bank. The bank assesses the business’s financial health, including its credit history, cash flow statements, and future revenue projections. Based on this assessment, the bank decides whether to offer the overdraft facility and determines the limit.
  2. Overdraft Limit: The overdraft limit is the maximum amount that the business can overdraw from its account. This limit is agreed upon by the bank and the business based on the business’s needs and creditworthiness.
  3. Accessing Funds: Once the overdraft facility is set up, the business can access funds up to the agreed limit. This means the business account can show a negative balance, allowing the business to continue making payments even when its account does not have sufficient funds.
  4. Interest and Fees: Interest is charged only on the amount overdrawn, and it is calculated daily. The interest rate for overdrafts is typically higher than that of traditional loans. There may also be additional fees for setting up the facility or for each transaction that uses the overdraft.
  5. Repayment Flexibility: The overdraft is repayable on demand, which means the bank can ask for the money back at any time. However, in practice, businesses can use the overdraft facility as long as they need, provided they stay within the agreed limit and make regular deposits into their account. Repaying the overdrawn amount reduces the interest charged.
  6. Renewal and Review: Overdraft facilities are usually reviewed annually by the bank. The bank may adjust the overdraft limit based on the business’s current financial situation, its repayment history, and any changes in the bank’s lending policies.
