Calculate semester and cumulative grade point averages from credit-weighted grades.
GPA is credit-weighted, so a high grade in a four-credit course moves the average more than the same grade in a one-credit course. The cumulative figure becomes progressively harder to shift as credits accumulate. After sixty credits a single strong semester moves the cumulative average by only a fraction of a point, which is why early grades matter disproportionately.
CGPA/SGPA
GPA = Σ(grade point × credits) ÷ Σ(credits)

This calculator takes 8 inputs: Course 1 grade point, Course 1 credits, Course 2 grade point, Course 2 credits, Course 3 grade point, Course 3 credits, Previous cumulative GPA, Previous credits earned. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
