What is my CGPA?
Put in each semester's GPA and how many credits that semester carried.
Put in at least one semester and its credits, and your CGPA will show up here.
How to calculate CGPA
A cumulative grade point average combines every semester into one figure. It is not the average of your semester GPAs, because semesters carrying more credits count for more.
Put in each semester's GPA and the credits that semester was worth. Multiply each GPA by its credits, add those together, then divide by the total credits.
It works on any scale
This calculator does not assume a 4.0 or a 10-point scale. It averages whatever numbers you give it, weighted by credits, so it works the same whether your semester GPAs come out of 4, 10 or anything else.
The answer comes back on the same scale you put in.
Common questions
How do I calculate CGPA?
Put in each semester's GPA and the number of credits that semester carried.
By hand: multiply each semester GPA by its credits, add those results together, then divide by the total credits across all semesters.
How do I convert CGPA to percentage?
There is no single formula, and this is the part people get caught by. The conversion is set by your board or university, not by any general rule.
Three are common. CBSE officially uses percentage = CGPA × 9.5. Many Indian universities use (CGPA − 0.75) × 10. Some simply use CGPA × 10. On a CGPA of 8, those give 76%, 72.5% and 80% — a spread of seven and a half points, which is more than enough to matter on an application.
Check which one your institution states before using any of them. We would rather tell you that than hand you a number that looks official and is wrong for your school.
Can I just average my semester GPAs?
Only if every semester carried the same number of credits. If they did not, averaging gives the wrong answer.
A semester of 24 credits should count for more than one of 12, and weighting by credits is what this calculator does.
What if I do not know my credits?
They are usually on your transcript or marksheet next to each course or semester, sometimes called credit hours or credit points.
If every semester genuinely carried the same load, you can enter the same number for each — say 1 for all of them — and the result will be the plain average.
