How to Calculate Semester Grade Point Average (SGPA)
The SGPA Calculator is a comprehensive academic tool designed to calculate your Semester Grade Point Average based on credit-weighted course grades. It supports both the standard 10-Point Scale (used across AICTE, UGC, VTU, Anna University, Mumbai University, and CBSE colleges) and the 4.0 US Grading Scale.
Step-by-Step Instructions:
- Select Your Grading Scale: Choose between the 10-Point Scale or the 4.0 International Scale.
- Select Percentage Formula: Select your university's approved conversion multiplier (e.g.
(SGPA - 0.75) × 10,SGPA × 9.5, orSGPA × 10). - Enter Courses & Credits: Input each course title, assign the credit hours for each subject, and select your letter grade from the dropdown list.
- Add or Remove Subjects: Click + Add Course to include labs, electives, or practicals, or click the trash icon to remove subjects.
- Instant Real-Time Result: Your weighted SGPA, total credits, total credit points earned, and equivalent percentage calculate dynamically.
The Standard SGPA Mathematical Formula
SGPA is calculated as the sum of credit points earned in all courses divided by the total credit hours registered in that semester:
SGPA Mathematical Equation:
SGPA = ∑ (Credit_i × GradePoint_i) / ∑ (Credit_i)
Where Credit_i is the course credit weight and GradePoint_i is the numeric point value awarded for your letter grade.
Standard 10-Point UGC Letter Grade Values
| Letter Grade | Academic Performance | Grade Point | Score Range |
|---|---|---|---|
| O | Outstanding | 10 | 90% - 100% |
| A+ | Excellent | 9 | 80% - 89% |
| A | Very Good | 8 | 70% - 79% |
| B+ | Good | 7 | 60% - 69% |
| B | Above Average | 6 | 55% - 59% |
| C | Average | 5 | 50% - 54% |
| P | Pass | 4 | 40% - 49% |
| F | Fail | 0 | < 40% |
Frequently Asked Questions
What is the difference between SGPA and CGPA?
SGPA (Semester Grade Point Average) measures academic performance in a single specific semester. CGPA (Cumulative Grade Point Average) represents the cumulative average of all your SGPAs across all semesters of your degree.
How do I convert SGPA to percentage?
The most widely used formula by UGC and CBSE is: Percentage (%) = (SGPA - 0.75) × 10. Some technical universities (like VTU) use SGPA × 9.5, while other institutions use direct multiplier SGPA × 10.
Can I calculate SGPA with labs and project credits?
Yes. Simply add a course row with the specific credit weight of your lab (e.g. 1.5 or 2 credits) and final year project (e.g. 6 or 8 credits).
