Grade Calculator

Introduction

A Grade Calculator is a handy tool for students and teachers to quickly estimate final grades. Instead of manually adding up scores and percentages, this calculator makes the process simple and accurate. By entering your assignment, quiz, exam, or project scores along with their weightage, you can instantly see your overall grade. This helps students track progress, plan better for future exams, and stay motivated. Teachers can also use it to save time when calculating weighted averages.

Formula / How It Works

Grades are usually calculated using a weighted average formula:

Final Grade = (Score₁ × Weight₁ + Score₂ × Weight₂ + … + Scoreₙ × Weightₙ) ÷ (Total Weight)

For example:

• Assignment: 85% (weight 20%)
• Midterm: 78% (weight 30%)
• Final Exam: 92% (weight 50%)

Final Grade = (85 × 20 + 78 × 30 + 92 × 50) ÷ 100 = 86.9% → Grade B.

The calculator applies this formula automatically to save time and reduce errors.

Step-by-Step Usage

1. Enter each assignment, quiz, or exam score.
2. Add the weight percentage for each score.
3. Click Calculate to see your overall grade.
4. Review results to check your performance.
5. Adjust “what-if” scores to predict future results.

Examples

• Example 1: Assignment 90 (30%), Midterm 80 (30%), Final Exam 85 (40%) → Final Grade = 85.5% (Grade B).
• Example 2: Quiz 75 (20%), Project 95 (30%), Final Exam 88 (50%) → Final Grade = 87.9% (Grade B+).
• Example 3: Assignment 60 (25%), Midterm 70 (25%), Final Exam 95 (50%) → Final Grade = 80% (Grade B).

These examples show how grades can vary depending on performance and weightage.
