GPA (Grade Point Average) is one of the most important academic performance indicators used worldwide. Students, universities, and employers rely on GPA to evaluate academic consistency, progress, and eligibility for admissions, scholarships, and career opportunities.
In this complete guide, you’ll learn:

• What GPA is and how it works
• GPA formulas and grading scales
• How to calculate GPA step by step
• Difference between cumulative, semester, and weighted GPA

What Is GPA?

GPA (Grade Point Average) is a numerical value that represents a student’s overall academic performance.
It is calculated by averaging the grade points earned in courses, weighted by the number of credits each course carries.
GPA is commonly measured on:

• 4.0 scale (most common worldwide)
• 5.0 scale (weighted GPA)
• 10.0 scale (some international systems)

GPA Grading Scale (4.0 Scale)

A GPA grading scale is a standardized system used by schools, colleges, and universities to convert letter grades or percentages into numerical values. This scale helps measure academic performance consistently across courses and semesters. While grading systems may vary by institution or country, the 4.0 GPA scale is the most widely used.

Formula For Calculating GPA

The standard GPA calculation formula is:
GPA = Total Grade Points ÷ Total Credits
Where:
Grade Points = Course Credits × Grade Value
Total Credits = Sum of all course credits

Types of GPA

1. Semester GPA

Semester GPA reflects your academic performance for a single term.
How to calculate it:
Multiply each course’s grade points by its credit hours, add the results, then divide by the total credit hours for that semester.

Formula:
Semester GPA = Total Grade Points ÷ Total Credit Hours

2. Cumulative GPA

Cumulative GPA represents your overall academic performance across all completed semesters.
How to calculate it:
Add all grade points earned from every semester and divide by the total credit hours attempted.

Formula:
Cumulative GPA = Total Cumulative Grade Points ÷ Total Cumulative Credit Hours

3. Weighted GPA

A Weighted GPA accounts for course difficulty, often giving extra points for honors, AP, or advanced courses.
How to calculate it:
Assign higher grade values to advanced courses, multiply by credits, then divide by total credits.

Weighted GPAs often use a 4.5 or 5.0 scale instead of the standard 4.0 scale.

4. Unweighted GPA

An Unweighted GPA treats all courses equally, regardless of difficulty, and typically follows a 4.0 scale.
How to calculate it:
Convert letter grades into standard grade points, calculate total grade points, and divide by total credits.

5. High School GPA

High school GPA may be weighted or unweighted depending on the institution.
How to calculate it:
Average all course grade points across subjects, factoring in credits if applicable.

6. College GPA

College GPA usually follows a credit-based system where each course contributes differently based on credit hours.
How to calculate it:
Multiply each course grade point by credit hours, sum them, then divide by total credits.
