CGPA Calculator - Check Your CGPA Online
An online CGPA calculator instantly computes your Cumulative Grade Point Average. Simply select your grading scale (e.g., 10.0 for India, 4.0 for USA), enter your grades and credit hours per semester, and the tool applies the standard formula: CGPA = Total Grade Points ÷ Total Credit Hours. It provides an accurate, weighted average of your academic performance across all semesters.
How the CGPA Formula Works
1. Gather Your Data
Collect your grades and the credit hours for each subject from your official transcript.
2. Convert & Multiply
Convert each letter grade to its equivalent grade point. Multiply this by the subject's credit hours.
3. Sum & Divide
Add all grade points and all credit hours. Divide the total points by total credits for your final CGPA.
The universally accepted formula for calculating CGPA is a weighted average. This ensures that subjects with higher credit hours contribute more significantly to your final score, providing a true measure of your academic effort. The formula is:
Standard Formula
CGPA = Σ (Grade Pointsᵢ × Credit Hoursᵢ) / Σ (Credit Hoursᵢ)

Frequently Asked Questions (FAQs)
How to calculate overall CGPA of all semesters?
Sum the total grade points earned across ALL semesters and divide by the sum of total credit hours from ALL semesters. Our tool does this automatically when you add more than one semester.
What is the difference between GPA and CGPA?
GPA (Grade Point Average) typically refers to a single semester's score. CGPA (Cumulative Grade Point Average) is the combined average of all semesters, giving a complete picture of your academic performance.
How to calculate CGPA from marks or percentage?
