What is Credit Card Interest?

What is Credit Card Interest?

We’ll help you decipher the jargon around Card interest so you really understand how it works when it applies to Credit Cards.
 

Credit Card Interest Explained

What is Credit Card interest?

When you use your Credit Card, you are borrowing money – and will be charged interest unless you repay the full balance within the specified period. The amount of interest you will be charged depends upon:

  • The interest rate of your Credit Card

  • The amount you spend

  • When you spend it

  • When you pay your Credit Card bill

  • When you receive your statements, the details of your purchases and the amount of interest you have been charged will be clearly displayed.

How is Credit Card interest calculated?

Interest is calculated on any unpaid balance from the due date of your previous month’s statement. It is applied to your closing balance at the end of each day and then added up to make the current statement.

What are interest Free Days?

'Interest free days' simply refers to the time from when you buy something using your Credit Card to when interest is applied to that purchase – which could be up to 25 days following the end of your statement period, depending on your Card.

To maximise your Credit Card's Interest Free Days, make your purchase on the day a new statement period begins and pay the closing balance by the due date shown on your statement.

In the example below, the Credit Card has 56 Interest Free Days and assumes that the previous month's balance has been paid in full.

 

Charge Card or Credit Card

Charge Card or Credit Card — what’s the difference?

A Charge Card is similar to a Credit Card in that they’re both convenient ways to pay for goods and services, with repayment delayed until the end of that particular statement period.

The main difference is a Charge Card requires you to pay off your balance in full each month, which means you cannot roll over your balance into the next month. If you like the stability of a debit card but are interested in extra benefits and rewards a charge card might be right for you.
