Using an APR Calculator

What is an APR Calculator?

An APR Calculator helps you work out your credit card APR after your interest / 0% interest-free period has expired. It uses simple logic such as your balance amount, your monthly payments and any contributions above your minimum payments to work out your current APR and potential payoff period. 

Why Should You Calculate APR?

APR is one way that banks make money - they make money from people who continue to pay their credit card even after the interest free period expires. As a consumer you should always calculate your APR to see how much you are paying over and above what other credit card companies offer. 

Is This APR Calculator Accurate?

Our APR calculator only uses your balance, monthly payments and any additional payments to calculate your APR, so whilst these are simple calculations, we may make mistakes and we advise you to check your bank terms and conditions to see what the exact APR conditions are. 

Why Does the Bank Matter in APR Calculations?

Banks have different APR rates. We use logic to try and determine what banks are charging and how much APR you might be paying, this allows us to get closer to a more accurate figure to help calculate your APR. 

What is APR, Anyway?

APR stands for annual percentage rate and it impacts your credit card payments negatively. Meaning, once your interest-free period has expired, you will be paying the bank this rate just to hold your outstanding balance. That's why balance transfers are so important and should always be top of mind for consumers. 

What Are Some Useful APR Resources?
