Understanding SGPA vs CGPA
SGPA
- Definition: Semester Grade Point Average
- Scope: Measures performance in a single semester
- Calculation: Based on individual subject performance in one semester
- Purpose: Track semester-specific performance
- Frequency: Calculated at the end of each semester
CGPA
- Definition: Cumulative Grade Point Average
- Scope: Measures overall academic performance
- Calculation: Average of all SGPAs or all subjects across all semesters
- Purpose: Represent holistic academic achievement
- Frequency: Updated after each semester's results
Your CGPA provides a more comprehensive view of your academic journey, while SGPA helps you track progress in individual semesters. Both metrics are important for different purposes, such as academic planning, scholarship applications, and job opportunities.

Subjects with higher credits have a greater impact on your SGPA/CGPA. Prioritize your study time accordingly.
Regular Assessment
Calculate your expected SGPA before exams to identify which subjects need more attention.
Track Your Progress
Monitor your SGPA trends across semesters to identify patterns and areas for improvement.
Balanced Approach
Instead of focusing only on weak subjects, maintain performance in subjects you're already good at.
Consistent Study Schedule

Form Study Groups
Collaborate with peers to understand difficult concepts and share resources for better results.
Frequently Asked Questions (FAQs)
SGPA (Semester Grade Point Average) measures your academic performance in a single semester only. CGPA (Cumulative Grade Point Average) represents your overall academic performance across all semesters combined. SGPA is like a snapshot of one semester, while CGPA shows your complete academic picture.
The accuracy of CGPA to percentage conversion depends on your university's specific formula. Our calculator uses the standard formula (Percentage = (CGPA - 0.5) × 10) which is commonly used across many Indian universities. For university-specific conversions, we provide options to select your university to apply the appropriate formula.
Yes, our calculator is designed to be compatible with most Indian universities that use the 10-point grading system. We also provide specific options for major universities like VTU, Anna University, Delhi University, and Mumbai University. If your university follows a different system, you can select the "Custom" option and adjust the settings accordingly.
For subjects with backlogs or failures, assign them a grade point of 0 (or the value your university assigns for failed courses). When you clear the backlog, use the new grade for calculation. In the "All Subjects" method of CGPA calculation, you can add the same subject twice with different semesters, marking the first attempt as failed and the second with your passing grade.
Yes, after calculating your SGPA or CGPA, you can save your results using the "Save Result" button. This will store your calculation in your browser's local storage so you can access it again on the same device. You can also share your results via email or social media using the "Share Result" option.
If your university uses a grading scale other than the standard 10-point system, select the "Custom" option in the university dropdown. This allows you to manually input grade points according to your university's system. For special cases, refer to your university's academic handbook for the exact grading criteria.
CGPA is very important for both job placements and higher education opportunities. Many companies set a minimum CGPA requirement (typically 7.0 or higher) for campus placements. For higher studies, especially abroad, universities often look at your academic performance through CGPA. A strong CGPA above 8.0 is generally considered excellent and opens up more opportunities for scholarships and admissions to prestigious programs.
