Don’t worry…we know it can be confusing. Here’s a bit more info to try and ease your fears and help you understand exactly what this offering is! Affirm quotes rates in terms of APR which, in the case of Affirm, would be the total interest paid over the course of a year assuming the entire principal balance remained unpaid for the entire year. With your Affirm purchase, you'll be making monthly payments over 3 or 6 months which reduce the balance that interest is calculated on each month. Your actual interest paid on the purchase will be significantly less than the APR multiplied by the ticket price.
