Do you want to know how good your marks are in a college semester? That’s where SGPA comes in. SGPA means Semester Grade Point Average. It helps you understand how well you did in your subjects. In this guide, you will learn how to calculate SGPA step by step in a very easy way. Even if you don’t like maths, don’t worry — this is super simple!
What is SGPA?
SGPA stands for Semester Grade Point Average. It shows your average performance in a semester based on the grades you scored in each subject. Every subject has a credit value, and each grade (like A, B, C) carries a specific grade point. SGPA is the weighted average of these grade points, based on the number of credits for each subject.
🧮 SGPA Formula
Here is the formula used to calculate SGPA:
SGPA = (Σ Credit × Grade Point) ÷ Σ Credits
- Credit = Number of credits assigned to a subject
- Grade Point = Numeric value of the grade received
- Σ = Sum of all values for the semester
📊 Grade Point Reference (Common Scale)
| Grade | Grade Point |
|---|---|
| O / A+ | 10 |
| A | 9 |
| B+ | 8 |
| B | 7 |
| C | 6 |
| P | 5 |
| F | 0 (Fail) |
(Note: This scale may vary slightly based on your university or board.)
📝 Step-by-Step: How to Calculate SGPA
Let’s break it down into easy steps with a real example.
📘 Example Subjects & Grades:
| Subject | Credits | Grade | Grade Point |
|---|---|---|---|
| Mathematics | 4 | A | 9 |
| Physics | 3 | B+ | 8 |
| Chemistry | 3 | A+ | 10 |
| English | 2 | B | 7 |
| Computer Lab | 2 | A | 9 |
✏️ Step 1: Multiply Grade Point × Credit for Each Subject
| Subject | Grade Point | Credits | Grade Point × Credits |
|---|---|---|---|
| Mathematics | 9 | 4 | 36 |
| Physics | 8 | 3 | 24 |
| Chemistry | 10 | 3 | 30 |
| English | 7 | 2 | 14 |
| Computer Lab | 9 | 2 | 18 |
Total Grade Points = 36 + 24 + 30 + 14 + 18 = 122
Total Credits = 4 + 3 + 3 + 2 + 2 = 14
✅ Step 2: Use the SGPA Formula
SGPA = Total Grade Points ÷ Total Credits
SGPA = 122 ÷ 14
SGPA = 8.71
So, the SGPA is 8.71 out of 10.
🔄 How to Calculate SGPA Using a Calculator or Excel
If you want to save time, you can use an SGPA calculator tool online or use Excel:
- Create a table with subjects, credits, and grade points.
- Multiply grade points with credits.
- Use Excel formula:
=SUM(Product of credits and grade points)/SUM(credits)
🎓 Why SGPA is Important
- Helps you track semester-wise performance.
- Required for calculating your CGPA (Cumulative Grade Point Average).
- Often asked in placement interviews, internships, and higher education applications.
🧠 Tips to Improve Your SGPA
- Focus more on high-credit subjects – they impact SGPA more.
- Submit assignments and practicals seriously.
- Avoid failing any subject (F grade = 0 points).
- Revise before exams and maintain consistency throughout the semester.
📌 Final Thoughts
Calculating SGPA is not rocket science. Once you understand the basics – credits and grade points – it becomes very easy. Whether you’re aiming for top scores or just want to track your academic progress, knowing your SGPA helps you stay on the right path.
Start tracking your grades from the first semester and take control of your academic journey.
