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.
