How to Calculate SGPA?
SGPA (Semester Grade Point Average) is the weighted average of grade points obtained in all subjects in a semester. It is calculated by multiplying each subject’s grade point with its credit value, adding them together, and dividing by total credits.
Formula: SGPA = Σ(Grade Point × Credits) ÷ Σ(Credits)
Example: If your total weighted grade points are 180 and total credits are 24, your SGPA is 180 ÷ 24 = 7.50.

Understanding SGPA and Grading Systems
The SGPA (Semester Grade Point Average) is a widely used metric in educational institutions across India, Pakistan, and the USA to evaluate a student’s academic performance for a specific semester. Unlike percentage, which calculates absolute marks, SGPA calculates the quality of performance relative to the credit weightage of subjects.
Using a semester GPA calculator helps students predict their scores before official results are declared. It is essential for planning academic improvements and ensuring eligibility for placements or higher studies.
The Official SGPA Formula
To calculate SGPA manually, you need to know the Grade Point awarded for each subject and the Credit assigned to that subject.
Where:
- Credit_i: The credit value of the i-th course.
- GradePoint_i: The grade point scored in the i-th course.
SGPA Calculation Example
Let’s assume a student has taken 3 subjects in a semester under the 10-point grading system.
| Subject | Grade Scored | Grade Point | Credits | Credit Points (C × G) |
|---|---|---|---|---|
| Mathematics | O (Outstanding) | 10 | 4 | 40 |
| Physics | A (Very Good) | 8 | 3 | 24 |
| English | B+ (Good) | 7 | 2 | 14 |
| Total | 9 | 78 |
Calculation: 78 (Total Credit Points) ÷ 9 (Total Credits) = 8.66 SGPA.
Grading Systems by Region
This tool automatically adjusts based on the region you select:
- India (10-Point Scale): Used by CBSE, AICTE, IITs, and most state universities. Grades range from O (10) to F (0).
- USA (4.0 Scale): The standard American GPA system. A = 4.0, A- = 3.7, etc.
- Pakistan (HEC): The Higher Education Commission follows a 4.0 scale where 85%+ is often 4.0, though this varies by university.
Tips to Improve Your SGPA
- Prioritize High-Credit Subjects: A 4-credit subject impacts your SGPA twice as much as a 2-credit lab. Secure top grades in these first.
- Internal Marks Matter: Internal assessments often carry 20-40% weightage. Scoring full marks here reduces the pressure on final exams.
- Use Calculators for Planning: Use this tool to run “what-if” scenarios. Example: “If I get an A in Math instead of a B, how much will my SGPA rise?”
