SGPA to CGPA Calculator
Add your SGPA from each semester and get your overall CGPA in one tap — with a percentage estimate too. Handles equal credits or credit-weighted semesters.
Turn Your Semester SGPAs Into One CGPA
Your SGPA tells you how a single semester went. Your CGPA is the number that actually goes on your transcript and gets asked about in placements and applications. This tool does the bridge between them: enter each semester's SGPA, hit calculate, and you get your cumulative CGPA plus a quick percentage estimate.
If all your semesters carry the same credits — which is the case for most students — your CGPA is just the average of your SGPAs, and you can leave the credit boxes empty. If your semesters have different credit loads, add the credits and the calculator switches to the exact credit-weighted formula. Either way it runs entirely in your browser, with nothing saved or sent anywhere.
The Maths Behind SGPA to CGPA
There are two versions, and which one is correct depends on your university.
Equal credits (the simple case):
CGPA = (SGPA₁ + SGPA₂ + … + SGPAₙ) ÷ number of semesters
Different credits (the weighted case):
CGPA = Σ(SGPA × credits) ÷ Σ(credits)
Most Indian universities — VTU, Anna University, JNTU, Mumbai University and others — publish their own rule, but in practice the credit-weighted average above is what they compute. If your semesters all carry roughly the same credits, the simple average lands within a rounding error of the official number anyway.
SGPA vs CGPA, in Plain English
- SGPA is a snapshot — how one semester went.
- CGPA is the full story so far — every semester rolled into one number.
- A weak semester drags your CGPA less as you add more semesters, because each one counts for a smaller slice of the whole.
What to Do With the Number
Once you know your CGPA, two things help. First, if you have a target in mind, work backwards: our GPA Goal Calculator shows what you need in upcoming semesters to get there. Second, if recruiters or universities want a percentage, run the CGPA through the CGPA to Percentage converter so you quote the figure your university actually recognises.
How to Use the SGPA to CGPA Calculator
- Enter the SGPA for your first semester.
- Click "Add Semester" and fill in each remaining semester.
- Add credits only if your semesters carry different credit loads (optional).
- Adjust the percentage multiplier if your university does not use 9.5.
- Click "Calculate CGPA" to see your cumulative CGPA and percentage.
Frequently Asked Questions
If every semester carries equal credits, your CGPA is the average of all your SGPAs. If semesters differ in credits, it is the credit-weighted average: multiply each SGPA by its credits, add them, divide by total credits. This calculator handles both.
SGPA is your average for a single semester. CGPA is your cumulative average across all completed semesters combined.
It depends on your university. CGPA × 9.5 is common (CBSE and several universities), but VTU, Mumbai and Anna University use different formulas. Use our CGPA to Percentage tool to apply the correct one.
No. Credits are optional. Leave them blank and every semester is weighted equally (a simple average). Add credits only if your semesters carry different credit loads.
