What is CGPA?
CGPA (Cumulative Grade Point Average) is a widely used educational metric that represents a student's overall academic performance throughout their entire program (such as a Bachelor's degree, Diploma, or High School). While an SGPA (Semester Grade Point Average) only calculates your performance for a single specific term, your CGPA combines all of your semesters together into one master score.
This calculator is built to be universally compatible. Whether your university uses a 4.0 US grading scale or a 10.0 scale (common in India, Europe, and Asia), simply enter your credits and your numerical GPA for each semester to get your true cumulative score.
How CGPA is Calculated
A common mistake students make is simply adding their SGPAs together and dividing by the number of semesters. This is mathematically incorrect unless every single semester had the exact same number of credits. To find your true CGPA, you must calculate a weighted average.
To find your Total Grade Points, you multiply your SGPA for a semester by the number of credits you took that semester. You repeat this for every semester, add all those points together, and then divide by your total lifetime credits.
Frequently Asked Questions (FAQ)
1. What is the difference between GPA, SGPA, and CGPA?
GPA stands for Grade Point Average and is usually applied to individual classes. SGPA (Semester Grade Point Average) combines all your classes for a single term. CGPA combines all your SGPAs across your entire academic program from start to finish.
2. How do I convert a 10.0 CGPA to a percentage?
While this rule changes depending on the specific university or board (such as CBSE or AICTE in India), the most widely accepted formula is to multiply your CGPA by 9.5. For example, a 9.0 CGPA would be (9.0 × 9.5) = 85.5%.
3. Can my CGPA go down if I do poorly in one semester?
Yes. Because CGPA is a running average, a bad semester will lower your overall score. However, the further along you are in your degree, the less impact a single bad (or good) semester will have, because your pool of "Total Credits" is so large that the new grades carry less mathematical weight.
