Your CGPA
0.00What This CGPA Calculator Does
This tool calculates a properly credit-weighted average across every course you enter, correctly accounting for the fact that a higher credit-hour course should count proportionally more toward your overall average than a lower credit-hour course, rather than simply averaging every course grade equally regardless of its credit weight.
How to Use the CGPA Calculator
Enter each course's letter grade or grade point value, along with that specific course's credit hours. Add as many courses as needed, spanning as many semesters as you want to include in your cumulative calculation. Your overall CGPA appears instantly once calculated, correctly weighted by credit hours across every entered course.
The CGPA Formula This Calculator Applies
CGPA is calculated as the sum of each course's grade point value multiplied by its credit hours, added together across all courses, then divided by the total sum of all credit hours. This weighted approach ensures a 4-credit course with a strong grade has proportionally more influence on your overall CGPA than a 1-credit course, correctly reflecting each course's actual contribution to your total academic workload.
Pro Tip: CGPA (Cumulative Grade Point Average) is calculated by taking the weighted average of each semester's GPA, using credit hours as the weight — giving you an overall average across your entire academic record.
CGPA = Σ (GPA × Credits) ÷ Σ Credits
Weighted average by credit hours.
Understanding the Difference Between Semester GPA and Cumulative CGPA
Semester GPA reflects performance within a single specific term, while cumulative CGPA reflects performance across every term completed to date. A single particularly strong or particularly weak semester tends to have a proportionally smaller impact on cumulative CGPA as more total semesters and credit hours accumulate over time, since CGPA essentially averages performance across an increasingly larger academic body of work.
How CGPA Relates to a Percentage Grade Scale
Many institutions using a 4.0 GPA scale also provide an approximate conversion to a percentage scale for reference, though the exact conversion formula varies somewhat between institutions and countries. Checking your specific institution's official conversion policy is worthwhile if you need an accurate percentage equivalent for a scholarship application, graduate school admission, or similar external requirement.
Frequently Asked Questions
Semester GPA reflects performance within one specific term, while cumulative CGPA reflects a credit-weighted average across every semester completed to date in a degree program.
A higher credit-hour course represents more of a student's total academic workload, so it should proportionally influence the overall average more than a lower credit-hour course, which simple unweighted averaging would not reflect correctly.
The impact tends to shrink as more total semesters and credit hours accumulate over time, since cumulative CGPA essentially averages performance across an increasingly larger overall body of academic work.
This calculator focuses on the standard 4.0-scale CGPA calculation. Percentage conversion formulas vary by institution, so checking your specific school's official conversion policy is recommended for precise external requirements.
GPA usually refers to one semester or term, while CGPA is your cumulative average across all semesters completed so far.
