Calculate your CGPA from subject-wise grade points and credits.
Your CGPA
8.11
Across 9 total credits
CGPA (Cumulative Grade Point Average) is not a simple average of your grade points โ it is a credit-weighted average, meaning subjects with more credit hours count for more. A 4-credit subject affects your CGPA more than a 2-credit subject, even if both have the same grade point.
This calculator lets you add each subject with its grade point (usually 0-10) and credit hours, and works out the correct weighted CGPA โ the same method your university actually uses.
Formula
CGPA = ฮฃ(Grade Point ร Credits) รท ฮฃ(Credits)
This is a credit-weighted average, not a plain average of the grade points.
Worked Example
Worked example
Why a simple average would be wrong
A plain average of 9, 7, and 8 would give 8.0 โ but because Subject A (grade point 9) carries more credits than Subject C (grade point 8), the correctly weighted CGPA of 8.11 is slightly higher, reflecting that the higher-scoring subject counted for more.
CGPA across multiple semesters
For a CGPA spanning several semesters, add every subject from every semester into this one calculation โ the credit-weighted formula naturally combines them correctly, without needing to average semester SGPAs separately.
Frequently Asked Questions
How is CGPA calculated?
Multiply each subject's grade point by its credit hours, add all of those up, then divide by the total credit hours โ this gives a credit-weighted average, not a simple average.
Is CGPA just the average of my grade points?
No โ a plain average ignores credit weighting. Two subjects with the same grade point but different credits should not count equally, which is why the credit-weighted formula is used instead.
Can I use this across multiple semesters at once?
Yes โ add every subject from every semester you want included, and the formula will correctly compute your combined CGPA in one step.
