📘 About the Semester GPA and Cumulative GPA

Your semester grade point average weights each course by its credits: a 4-credit course counts twice as much as a 2-credit one. Your cumulative average combines all semesters in the same way, which is why one good or bad semester moves it less as you progress.

Type a letter grade (O, A+, A, B+ … on the 10-point scale; A, A−, B+ … on the 4.0 scale) or the grade point itself. Add your previous CGPA and credits to see the new cumulative figure, and a target to find the GPA you need next semester.

🧮 Formula

SGPA / GPA

Σ(grade point × credits) ÷ Σ credits

New CGPA

(previous CGPA × previous credits + this semester's points) ÷ total credits

Percentage (AICTE)

❓ Frequently asked questions

What is the difference between SGPA and CGPA?

SGPA is the grade point average for one semester; CGPA is the credit-weighted average of all semesters so far.

How do I convert CGPA to percentage?

AICTE and many universities use (CGPA − 0.75) × 10; CBSE used CGPA × 9.5. Check your university's rule.

Can I raise my CGPA from 7 to 8?

It depends on credits done. With 120 credits at 7.0, you need about 8.0 in the remaining credits only if they are as many again; the calculator's target option shows what one semester can do.
