How Semester GPA and Overall CGPA Are Calculated
Semester GPA (SGPA) is calculated as the credit-weighted average of the grade points you scored in each subject: SGPA = Σ(Credit × Grade Point) ÷ Σ(Credit). A subject with more credit hours has a bigger impact on your GPA than one with fewer credits.
Overall CGPA combines all your completed semesters the same way — it's the credit-weighted average of your semester GPAs across every semester you've finished: CGPA = Σ(Semester GPA × Semester Credits) ÷ Σ(Semester Credits).
This calculator works with any grading scale — 10-point (used by most Indian universities including Anna University and VTU), 4-point (used by some private/international universities), or any custom scale — since you enter the grade points directly rather than picking from a fixed list.

SGPA (Semester Grade Point Average) is your credit-weighted average for one semester only. CGPA (Cumulative Grade Point Average) is the credit-weighted average across all semesters you've completed so far. Your CGPA updates every semester as new SGPAs are added.
Check your university's official grade point mapping (for example, many Indian universities use O=10, A+=9, A=8, B+=7, B=6, C=5, P=4), then enter the numeric grade point for each subject in this calculator instead of the letter grade.
Yes. GPA is a weighted average, so a 4-credit subject influences your GPA twice as much as a 2-credit subject with the same grade point. This is why doing well in high-credit core subjects matters more than in low-credit electives.
Yes — since you enter the grade point value directly (not a letter grade), this calculator works for any scale your university uses, whether that's a 10-point Indian university scale or a 4.0 US-style scale.
