Section 8-6: Determining the APR

APR, or Annual Percentage Rate, is a standardized way of expressing the cost of borrowing money, including interest rates and certain fees, over the course of a year. To determine the APR, you'll need to consider several factors, including the interest rate, any additional fees or charges, and how often interest is compounded.

Here's a general formula to calculate APR:

​

Here's a breakdown of the terms used in the formula:

• Number of Payments: This is the total number of payments you'll make over the term of the loan.
• Finance Charge: The total cost of borrowing, including interest and any other fees.
• Principal Balance: The original amount of money borrowed.
• Total of Payments: The sum of all payments made over the term of the loan.
• Term of Loan: The length of time over which the loan is repaid, typically expressed in years.

Here's a step-by-step guide to calculating APR:

1. Determine the finance charge: This includes any interest charges and fees associated with the loan.
2. Calculate the total of payments: Add up all the payments you'll make over the term of the loan.
3. Plug the values into the formula and solve for APR.

Keep in mind that APR calculations can vary depending on the specifics of the loan, such as whether it's a fixed-rate or variable-rate loan, whether there are any introductory rates or promotional periods, and whether there are penalties for early repayment. If you're unsure about how to calculate the APR for a particular loan, it's always best to consult with a financial advisor or use an online APR calculator.
