Principal Amount: Nominal Interest Rate (%): Compounding Periods per Year: Calculate Annual Percentage Rate (APR):

 

Introduction

Calculating the Annual Percentage Rate (APR) is crucial when assessing the true cost of borrowing, whether it’s for a loan or credit card. An APR calculator simplifies this process, providing users with an accurate representation of the annualized interest rate. In this article, we’ll guide you through creating a simple and effective APR calculator using HTML and JavaScript.

How to Use

To utilize the APR calculator, follow these steps:

1. Input the principal amount (loan amount).
2. Enter the nominal interest rate.
3. Specify the number of compounding periods per year.
4. Click the “Calculate” button to obtain the APR.

Formula

The formula for calculating APR is as follows:

=(1+)−1APR=(1+nr​)n−1

Where:

• $r$ is the nominal interest rate (decimal).
• $n$ is the number of compounding periods per year.

Example 

Let’s consider an example:

• Principal amount: $10,000
• Nominal interest rate: 5%
• Compounding periods: 12 times per year

=(1+0.0512)12−1APR=(1+120.05​)12−1

After evaluating this expression, the APR is approximately 5.12%.
