Credit card interest rates

Credit card interest rates

The interest rate on purchases is the rate that you will be charged for each purchase you make on your credit card. Essentially the lower the interest rate the less interest you have to pay, however if you make use of the interest free period and pay off your balance in this time you will not be charged interest.

Usually a financial institution will charge one interest rate on purchases and one interest rate for cash advances (withdrawals) and this rate is normally a lot more.

Interest rates will be different between financial institutions, so it pays to compare credit cards online to find a card that offers the lowest rates.

How does credit card interest work?

Generally, when we talk about credit card interest, we mean the purchase interest rate, which is the interest charged on purchases you make with your credit card.

If you don’t pay your full balance each month (or even if you pay the minimum amount), you are charged interest on all the outstanding transactions and the remaining balance. However, interest is also charged on cash advances, balance transfers, special rate offers and, in some cases, even the fees charged by the company.

The interest rate can vary, depending on the credit card. Some have an interest-free period, otherwise you start paying interest from the day you make a purchase or from the day your monthly statement is issued. So avoid interest by paying the full amount promptly.

Current Interest Rate

This is the current interest rate on your existing credit card.

How is credit card interest charged?

Your credit card will be charged interest when you don’t pay off the balance on your credit card. Your card provider or bank charges you the individual interest rate that is associated with your card, which is usually between 10 and 20 per cent. 

The interest will be added onto your bill each month or billing period if you don’t pay off the balance, unless you are in an interest-free period.

You will be charged interest on anything that hasn’t been paid for inside the interest-free period. Usually you will receive a notice on your bill or statement saying you will be charged interest so you have some form of notice before you’re charged.

How to calculate credit card interest

Credit card interest can quickly turn a manageable balance into unmovable debt. So being able to understand how interest rates translate into dollars is an important skill to acquire.

The common mistake people make is focusing on the credit card’s annual percentage rate (APR), which often sits between 15 and 20 per cent. While the APR does provide a rough idea of how much interest you’ll pay, it’s not entirely accurate.

This is because you actually accrue interest on your balance daily, not annually. So, you need to work out your daily periodic rate (DPR). To do this, divide your card’s APR by the number of days in a year (e.g. 16.9 per cent divided by 365, or 0.05 per cent). You can then apply this figure to the daily balance on your credit card.

How do you use a credit card?

Credit cards are a quick and convenient way to pay for items in store, online or over the phone. You can use a credit card as a cashless way to pay for goods or services, both locally and overseas. You can also use a credit card to make a cash advance, which gives you the flexibility to withdraw cash from your credit card account. Because a credit card uses the bank’s funds instead of your own, you will be charged interest on the money you spend – unless you pay off the entire debt within the interest-free period. If you pay the minimum monthly repayment, you will be charged interest. There are many different credit card options on the market, all offering different interest rates and reward options.

Should I get a credit card?

Once you've compared credit card interest rates and deals and found the right card for you, the actual process of getting a credit card is quite straightforward. You can apply for a credit card online, over the phone or in person at a bank branch. 

What is a balance transfer credit card?

A balance transfer credit card lets you transfer your debt balance from one credit card to another. A balance transfer credit card generally has a 0 per cent interest rate for a set period of time. When you roll your debt balance over to a new credit card, you’ll be able to take advantage of the interest-free period to pay your credit card debt off faster without accruing additional interest charges. If your application is approved, the provider will pay out your old credit card and transfer your debt balance over to the new card. 

How do you use credit cards?

A credit card can be an easy way to make purchases online, in person or over the phone. When used properly, a credit card can even help you manage your cash flow. But before applying for a credit card, it’s good to know how they work. A credit card is essentially a personal line of credit which lets you buy things and pay for them later. As a card holder, you’ll be given a credit limit and (potentially) charged interest on the money the bank lends you. At the end of each billing period, the bank will send you a statement which shows your outstanding balance and the minimum amount you need to pay back. If you don’t pay back the full balance amount, the bank will begin charging you interest.

Can a pensioner get a credit card?

It is possible to get a credit card as a pensioner. There are some factors to keep in mind, including:

  • Annual income. Look for credit cards with minimum annual income requirements you can meet. 
  • Annual fees. If high fees are a concern for you, opt for a card with a low or $0 annual fee. 
  • Interest rate. Make sure you won’t have any nasty surprises on your credit card bill. Compare cards with a low interest rates to minimise risk.

Which credit card has the highest annual percentage rate?

The credit card market changes all the time, so the credit card with the highest annual percentage rate is also liable to change.

Keep in mind that credit card interest rates are expressed as a yearly rate, or annual percentage rate (APR). A low APR is generally good but also consider:

  • There can be different APR's for each feature of the card (e.g. purchases may have an APR of 14 per cent, while cash advances on same card could have an APR of 17 per cent.
  • Credit cards with a variable rate can change throughout the year, affecting your APR, so check the full details.
  • If you pay your balance in full every month, having the lowest APR is not as important as the other fees associated with the card. However, if you carry a balance from month to month, then you want the lowest APR possible.

How to get money from a credit card

You can get money from a credit card, but generally it will cost you.

Withdrawing money from a credit card is called a cash advance, as it operates more as a loan than a simple cash withdrawal. Because it is a loan, you may be charged interest on your cash advance as soon as you make the withdrawal. Interest rates are also usually much higher for cash advances than standard credit card purchases.

In addition to the interest rate, you may also be charged a cash advance fee. This could be a flat rate, or a percentage of your total cash advance. If you are considering a cash advance, make sure to add up how much it will cost you before committing.

How to increase the NAB credit card limit?

If you use your NAB credit card regularly, you could consider requesting a higher credit limit. The good news is that it's fairly easy to do so using either the NAB app or NAB internet banking. 

NAB app: 

Step 1: Download the latest version of the NAB app.

Step 2: Select the ‘My Cards’ menu. 

Step 3: Select the card you want to increase the credit limit for. 

Step 4: Select ‘Usage Controls’ and then click on ‘Change Credit Limit’.

NAB internet banking: 

Step 1: Log into your account. 

Step 2: Choose the ‘My Cards’ menu. 

Step 3: Choose the card for which you want to increase the limit. 

Step 4: Choose ‘Change My Credit Card Limit’.  

If you don’t have the NAB app or cannot access NAB internet banking, you can even visit your local branch or call their contact center. 

Once you’ve applied to increase your NAB credit card limit, you’re likely to be asked for your

  • current employment details  
  • total income, before and after-tax deductions  
  • assets, liabilities, and expenses information

NAB will then assess this information to determine if your current financial situation suits the increased credit limit request, and your application will either be accepted or denied.

However, this process will only work if you’re attempting to increase your personal NAB credit card limit. For a business credit card, you can contact the NAB Corporate & Business Servicing team or speak to your NAB relationship manager. 

What does ANZ credit card insurance cover?

ANZ offers complimentary insurance on some of its credit cards, which can provide some protection against unforeseeable incidents, like the theft of your card. Depending on the type of credit card you own, you may be eligible for different insurances. For instance, most ANZ credit card customers may qualify for Purchase Protection Insurance and Extended Warranty Insurance. Customers who own premium credit cards may also be eligible for Guaranteed Pricing, Rental Vehicle Excess, International Travel, and so on.

Consider checking your ANZ credit card insurance features listed in the Insurance Policy Information booklet to know which items are covered. Also, while ANZ issued the credit card, they are not the insurer. For this reason, you may need to send your insurance claims - and get your ANZ credit card insurance refund - to the insurance provider.
