How to Calculate CGPA / SGPA
Calculating your Cumulative Grade Point Average (CGPA) or Semester Grade Point Average (SGPA) manually can be confusing due to credit weightings. Our calculator does the heavy lifting for you based on the standard 10-point credit system used by most universities worldwide.
The Formula
The mathematical formula used to calculate your GPA is:CGPA = Σ (Credit_i × GradePoint_i) / Σ (Credit_i)
In simple terms: Multiply the credits of each subject by the grade point you achieved. Add all those numbers together. Finally, divide that sum by the total number of credits you took.
Using the Calculator
- Subject Name: (Optional) Helps you keep track of what you're entering.
- Credits: The academic weight of the subject (usually 1, 2, 3, or 4).
- Grade Point: The score you achieved on a 10-point scale (e.g., an 'A' might be a 9 or 10).
Frequently Asked Questions
What is the difference between SGPA and CGPA?
SGPA (Semester Grade Point Average) is the average of grade points you earn in a single semester. CGPA (Cumulative Grade Point Average) is the average of your grade points across all completed semesters in your course.
How do I use this to calculate SGPA?
To calculate SGPA for a single semester, add each subject you took in that semester, along with its specific credit weight and the grade point you achieved. The resulting number is your SGPA.
How do I calculate overall CGPA across semesters?
To calculate your overall CGPA, you can enter your SGPA for each semester. Just treat each 'Subject' row as a 'Semester', enter the total credits for that semester, and the SGPA you achieved as the 'Grade Point'.
How is CGPA converted to percentage?
Most Indian universities and boards (like CBSE) use a standard conversion formula: Percentage = CGPA × 9.5. However, some autonomous universities might use CGPA × 10 or have a specific formula. Always check with your university's official guidelines.
