Master Your Academic Performance with Easy Calculations, Formulas & Conversion Tables
Calculating your Cumulative Grade Point Average (CGPA) is crucial for tracking academic performance, applying to higher education programs, and securing employment opportunities.
Whether you're a student in India following the 10-point scale or pursuing international education with 4.0 or 5.0 grading systems, understanding CGPA calculations empowers you to make informed academic decisions.
This comprehensive guide covers everything you need to know about CGPA calculations, including formulas, conversion methods, grading scales, and practical examples.
What is CGPA? Complete Definition & Overview
CGPA (Cumulative Grade Point Average) is a standardized grading method used by educational institutions worldwide to evaluate a student's overall academic performance across multiple semesters or academic years.
It represents the average of grade points obtained in all subjects, considering their credit weightage.
Key Points About CGPA:
- Provides a unified metric for academic assessment
- Used by universities, colleges, and employers for standardized comparison
- Calculated on different scales: 4.0, 5.0, or 10.0 depending on the institution
- Considers credit hours to give appropriate weightage to each subject
- Widely accepted for higher education admissions and job applications
🎓 Academic Standard
CGPA provides a consistent measure of student performance across different subjects and semesters, making it easier to assess overall achievement.
🌍 Global Recognition
Recognized internationally, CGPA allows seamless comparison of academic credentials across different educational systems.
📈 Performance Tracking

CGPA vs GPA vs SGPA: Understanding the Differences
Many students confuse these three terms.
Here's a clear breakdown of their differences:
| Term | Full Form | Scope | Calculation Period |
|---|---|---|---|
| GPA | Grade Point Average | Single semester or term | One academic term only |
| SGPA | Semester Grade Point Average | Specific semester | One semester (same as GPA) |
| CGPA | Cumulative Grade Point Average | All semesters combined | Entire academic program |
💡 Important Note: GPA and SGPA are often used interchangeably, as both refer to a single semester's performance.
CGPA, however, represents the cumulative average of all SGPAs throughout your academic journey.
How to Calculate CGPA: Step-by-Step Guide
Calculating CGPA manually involves a systematic approach.
Follow these detailed steps to accurately determine your CGPA:
Identify Subject Grades
Collect the grades or marks obtained in each subject. These are typically provided on your mark sheet as letter grades (A+, A, B+, etc.) or numerical scores.
Convert Grades to Grade Points
Use your institution's grading scale to convert letter grades to numerical grade points. For example, on a 10-point scale: A+ = 10, A = 9, B+ = 8, etc.
Determine Credit Hours
Find the credit hours assigned to each subject. Credits reflect the subject's importance or time commitment (typically 1-4 credits per subject).
Calculate Weighted Grade Points
Multiply each subject's grade points by its credit hours. This gives you the weighted grade points for that subject.
Sum Total Weighted Points
Add up all the weighted grade points from all subjects across all semesters to get the total weighted grade points.
Sum Total Credits
Add up all the credit hours from all subjects across all semesters to get the total credits attempted.
Divide to Get CGPA
Divide the total weighted grade points by the total credits. The result is your CGPA.
CGPA Calculation Formulas (All Grading Scales)
