What is an Overdraft? | Definition, Types, and How to Avoid Fees
Overdrafts can be a convenient way to cover unexpected expenses, but they can also be expensive. In this article, we will discuss what an overdraft is, the different types of overdrafts, and how to avoid overdraft fees.
You will also learn about the pros and cons of using an overdraft, and when it is not the best option.
Definition of Overdraft
An overdraft is a type of short-term loan that allows you to spend more money than you have in your bank account.
When you use your overdraft, your bank will lend you the money you need, and you will have to pay it back with interest.

Types of Overdrafts
There are two main types of overdrafts: authorised overdrafts and unauthorised overdrafts.
Authorised overdrafts are overdrafts that you have agreed to with your bank. When you open a bank account, you may be offered an authorised overdraft limit. This is the maximum amount of money that your bank will lend you if you go overdrawn.
Unauthorised overdrafts are overdrafts that you have not agreed to with your bank. These can happen if you make a payment that exceeds your available balance, or if you do not have enough money in your account to cover a bounced check.
Why Do People Use Overdrafts and How Do Overdrafts Work?
People use overdrafts for a variety of reasons, including:
- To cover unexpected expenses, such as a medical bill or car repair.
- To bridge the gap between paychecks.
- To make a large purchase that they cannot afford to pay for in full right away.
- To build their credit history.
Overdrafts work by allowing you to spend more money than you have in your bank account. When you use your overdraft, your bank will lend you the money you need, and you will have to pay it back with interest.
When you use your overdraft, your bank will charge you a fee. The amount of the fee will vary depending on your bank and your overdraft limit.
Overdrafts can be a convenient way to cover unexpected expenses, but they can also be expensive. If you’re considering using an overdraft, it’s important to weigh the pros and cons carefully.
How Much Do Overdraft Fees Cost?
An overdraft fee is a charge that a bank may charge you if you spend more money than you have in your account. Overdraft fees can be expensive, and they can add up quickly if you’re not careful.
The amount of an overdraft fee varies depending on your bank and your overdraft limit. However, overdraft fees typically range from $30 to $35 per transaction. Some banks may also charge a daily overdraft fee, which is a fee that is charged each day that your account is overdrawn.
How to Avoid Overdraft Fees
Overdraft fees can be a major financial burden, especially if you’re struggling to make ends meet. If you’re concerned about overdraft fees, there are a few things you can do to avoid them:
- Set up a budget and track your spending. This will help you to avoid spending more money than you have.
- Make sure that you know your authorised overdraft limit. Don’t spend more money than your authorised overdraft limit, or you will be charged an overdraft fee.
- Sign up for overdraft protection. Overdraft protection is a service that allows your bank to cover your overdrafts with a line of credit or a linked savings account. This can help you to avoid overdraft fees, but it may also come with fees of its own.
- Pay back your overdraft as soon as possible. The longer you take to pay back your overdraft, the more interest you will have to pay.
- If you do go overdrawn, be sure to talk to your bank about your options. Some banks may be willing to waive or reduce your overdraft fees if you’re experiencing financial hardship.
- Use a credit card instead of your debit card. Credit cards do not typically charge overdraft fees, so you will only be charged interest if you do not pay your bill in full each month.
- Link your checking account to a savings account. This way, if you go overdrawn, your bank can automatically transfer money from your savings account to cover the overdraft.
- Set up alerts on your phone or email so you are notified when your account balance is low. This will give you a warning before you go overdrawn and allow you to transfer money into your account or make other arrangements.
Overdraft fees can be a costly burden, but there are steps you can take to avoid them. By following these tips, you can protect your finances and avoid paying unnecessary fees.

Frequently Asked Questions
What is an overdraft?
An overdraft is a type of short-term loan that allows you to spend more money than you have in your bank account. When you use your overdraft, your bank will lend you the money you need, and you will have to pay it back with interest.
What are the different types of overdrafts?
There are two main types of overdrafts: authorised overdrafts and unauthorised overdrafts.
- Authorised overdrafts are overdrafts that you have agreed to with your bank. When you open a bank account, you may be offered an authorised overdraft limit. This is the maximum amount of money that your bank will lend you if you go overdrawn.
- Unauthorised overdrafts are overdrafts that you have not agreed to with your bank. These can happen if you make a payment that exceeds your available balance, or if you do not have enough money in your account to cover a bounced check.
How do overdraft fees work?
Overdraft fees are charged by banks when you spend more money than you have in your account. The amount of the overdraft fee varies depending on your bank and your overdraft limit. However, overdraft fees typically range from $30 to $35 per transaction. Some banks may also charge a daily overdraft fee, which is a fee that is charged each day that your account is overdrawn.
How does an overdraft differ from a home loan?
An overdraft is typically a short-term borrowing solution that allows you to access funds up to an agreed limit, whereas a home loan is a longer-term commitment used to purchase property.
Australian mortgages usually have lower interest rates compared to overdrafts, but they come with fixed repayment terms. If you are looking for how an Australian mortgage works and if it’s the right option for you, consult with an experienced mortgage broker.
Therefore, while both an overdraft and a home loan are forms of credit, they serve different purposes.
How do the types of home loans compare to an overdraft in terms of flexibility?
When comparing the types of home loans in Australia with an overdraft, the key difference lies in flexibility and purpose. An overdraft provides immediate access to funds with flexible repayment terms, but it is usually intended for short-term needs, such as covering day-to-day expenses.
On the other hand, the various types of home loans, such as fixed-rate loans, variable-rate loans, and interest-only loans, are designed for long-term borrowing, typically for purchasing property. While home loans come with structured repayment schedules and specific lending terms, overdrafts are more flexible but often come with higher interest rates and fees for prolonged use.
Is an overdraft a good alternative to a home loan?
An overdraft is not a suitable alternative to a home loan. The Australian mortgage lending process is specifically designed for long-term property purchases, involving structured applications, approvals, and repayments.
In contrast, an overdraft is a short-term credit facility meant for covering immediate expenses, often with higher interest rates and no long-term repayment plan.
