The APR, in short, is the annualized interest rate applied on a loan or a credit card. The APR charged by a lender is higher than monthly interest rate because APR includes all the fees associated with the loan.
Let’s consider an example. You have taken a loan of $600 from Chase for a term of 12 month with 5% interest rate. All other extra fees amount to $200. What should be the APR for such a loan? Well, it would be approximately 62% as per APR calculators.
Remember that APR is an important factor when it comes to comparing credit cards, but you should consider other factors (like the method used to calculate penalties) as well. Most importantly, you must make as much payments as possible every month so that you do not end up paying more on interest.
