How credit cards work

A credit card lets you buy goods and services, up to an approved credit limit, which you’ll then pay back later.

When you use your credit card, we’re lending you money and you’ll need to repay it. We may charge you interest on that money, and there may be fees you need to pay. 

This is different from a debit or EFTPOS card, where you’re usually spending money, you already have in your bank account.

For example, if you use your credit card to buy something for $100, you’re borrowing $100. You’ll need to pay that money back.

As you pay back what you’ve borrowed, the amount becomes available for you to borrow again, up to your credit limit.

You may also need to pay interest or fees, depending on how you use your card and how much you pay back each month.

Interest and fees

How interest works

Interest is the cost of borrowing money. An interest rate is the annual percentage rate we charge for borrowing money.  

We calculate interest differently for different transaction types. Purchases, cash advances and balance transfers have their own interest rates. 

For purchases, you generally won’t pay interest if you pay your closing balance in full by the due date.  

If you don’t pay your closing balance in full, you’ll generally be charged interest on your purchases. This means you can end up paying more than the original cost of what you bought.  

For example, if you buy something for $500 and don’t pay your credit card balance in full, you could end up paying more than $500 for that purchase because interest is added to what you owe. 

The longer you carry an unpaid balance, the more interest you may pay.  

See our current credit card interest rates. 

How paying back your credit card works

Each month, we’ll send you a credit card statement. Think of your statement as a monthly summary of your credit card. 

It shows: 

  • What you’ve spent
  • Any payments you’ve made
  • Any interest or fees you’ve been charged
  • How much you owe
  • The minimum amount you need to pay
  • When your payment is due.
Paying in full vs paying the minimum

What you choose to pay can affect how much interest you’re charged and how long it takes to repay what you owe.
