GPA Calculator

How does the GPA Calculator Work?

Grade Point Average (GPA) is a standard method of measuring academic achievement in schools and universities. Your GPA represents the average value of your accumulated final grades over a semester or complete course of study.

The GPA Formula

GPA is calculated as a weighted average where each course's grade points are multiplied by its credit value, summed, and then divided by the total credits:

Standard 4.0 Grade Point Scale

Most universities use a standard 4.0 scale to convert letter grades to numerical points:

• A+ / A: 4.0 points
• A-: 3.7 points
• B+: 3.3 points
• B: 3.0 points
• B-: 2.7 points
• C+: 2.3 points
• C: 2.0 points
• D: 1.0 point
• F: 0.0 points

Step-by-Step Worked Example

Suppose you are taking 3 courses in a semester:

1. Course 1: Grade A (4.0 points), 3 Credits. Grade points = 4.0 x 3 = 12.0.
2. Course 2: Grade B (3.0 points), 4 Credits. Grade points = 3.0 x 4 = 12.0.
3. Course 3: Grade C (2.0 points), 2 Credits. Grade points = 2.0 x 2 = 4.0.
4. Total Grade Points: 12.0 + 12.0 + 4.0 = 28.0.
5. Total Credits: 3 + 4 + 2 = 9.
6. Apply formula: GPA = 28.0 / 9 = 3.11.
