Introduction

Calculating GPA using percentages is a common requirement for students worldwide. With the advent of technology, creating a GPA calculator using HTML and JavaScript offers a convenient and efficient way to determine academic performance. This article provides a step-by-step guide on building a GPA calculator with a user-friendly interface.

How to Use

To use the GPA calculator, follow these simple steps:

Input the percentage obtained in each subject.
Click the “Calculate” button.
The GPA result will be displayed instantly.

This calculator is designed to provide accurate results based on a widely accepted formula for GPA calculation.

Formula

The GPA is typically calculated using the following formula:

$GP A = Σ Credit Hours Σ ( Grade Points \times Credit Hours )$

Where:

$Σ$ represents the sum.
“Grade Points” are assigned based on the percentage obtained.
“Credit Hours” are the weight assigned to each course.

Example

Let’s consider an example with three courses:

Mathematics (4 credit hours, 85%)
Science (3 credit hours, 90%)
English (2 credit hours, 75%)

$GP A = 4 + 3 + 2 ( 4 \times 3.6 ) + ( 3 \times 4.0 ) + ( 2 \times 2.0 )$

$GP A = 9 14.4 + 12.0 + 4.0$

$GP A = 9 30.4$

$GP A \approx 3.38$

FAQs
