Roughly where this sits academically

GPA is a credit-weighted average, so a four-credit course moves it twice as far as a two-credit one with the same grade. Cumulative GPA combines total grade points over total credits — you cannot simply average semester GPAs unless every semester carried identical credits.

Quick Tool Overview

The GPA Calculator computes a semester grade point average from your courses and credit hours, then rolls it into a cumulative figure using your existing GPA and credits. Both unweighted 4.0 and weighted honours or AP scales are supported.

About the GPA Calculator

Calculate a semester GPA from your courses and credit hours, then roll it into a cumulative figure using your existing GPA and credits. Both unweighted and weighted scales are supported, with the extra points that honours and AP courses carry.

GPA is a credit-weighted average rather than a simple one, which is the detail that trips people up: a four-credit course moves your average twice as far as a two-credit course with the same grade. The calculator makes that visible by showing each course's contribution in grade points, so you can see where the number is actually coming from and what a change in any one course would do to it.

Key features of the GPA Calculator

Credit-weighted, correctly

A four-credit course moves your average twice as far as a two-credit one, and the tool shows each contribution.

Weighted and unweighted

Extra points for honours and AP courses, so a weighted GPA above 4.0 is calculated properly.

Cumulative rollup

Combines this semester with your existing record, rather than incorrectly averaging semester GPAs.

Per-course grade points

Shows where the number comes from, so you can see what changing one course would do.

Add as many courses as you need

Rows can be added or removed freely, and everything recalculates instantly.

Multiply each course grade point by its credit hours, add those products, then divide by the total credit hours. It is a weighted average, so bigger courses count for more.
