Depending on what you use your credit card for, you can encounter a few different types of APR. - Introductory APR is often offered to new cardholders with a promotional 0% APR. - Regular or Purchase APR will be incurred for your everyday purchases. - Balance transfer APR will be applied when you transfer your balance from one card to another. If you use an ATM for borrowing money from your credit card, you will have to pay the Cash Advance APR, and finally, if you’re 60 days late on making a payment, you will have to pay the Penalty APR. The exact rates will be listed in the Pricing and Information section of your credit card agreement.
