Percentage Weight Calculator Grades

Introduction

Calculating percentage weights for grades is a common task in educational contexts, where different assignments contribute varying proportions to the final grade. Creating a user-friendly calculator to streamline this process can be immensely helpful. In this article, we will provide a simple and effective HTML and JavaScript code for a percentage weight calculator for grades.

How to Use

To utilize the calculator, simply enter the percentage weights of each assignment or exam in the provided input fields. Click the “Calculate” button, and the result will display instantly. This tool simplifies the process of determining overall grades based on different weightings assigned to various components.

Formula

The formula used for calculating the overall percentage weight is as follows:

$Overall Percentage Weight = Total Weight ( Weight ^{1} \times Grade ^{1} + Weight ^{2} \times Grade ^{2} + \dots + Weight ^{n} \times Grade ^{n} )$

Where:

$Weight_{i}$ is the percentage weight of the $i$ -th component.
$Grade_{i}$ is the grade achieved in the $i$ -th component.
$Total Weight$ is the sum of all percentage weights.

Example

Let’s consider an example with three components:

Assignment 1: Weight – 30%, Grade – 85
Assignment 2: Weight – 40%, Grade – 92
Final Exam: Weight – 30%, Grade – 78

$Overall Percentage Weight = 100% ( 30% \times 85 + 40% \times 92 + 30% \times 78 )$

$Overall Percentage Weight = 100 ( 25.5 + 36.8 + 23.4 )$

$Overall Percentage Weight = 100 85.7 = 0.857 \times 100 = 85.7%$
