Grade Calculator — Overview

The Grade Calculator helps students determine their overall course grade by calculating a weighted average of their assignment, quiz, test, and exam scores. Most university and college courses assign different weight percentages to different assessment types — for example, homework might count for 20%, midterms for 30%, and the final exam for 50%. Simply averaging all scores without accounting for these weights will give an incorrect result. This tool lets you enter each grade category, its earned score, and its weight percentage, then instantly calculates the weighted final grade. It also supports what-if scenarios: you can leave a future assignment blank to see what score you would need to achieve a target grade, helping you plan your study efforts strategically. The tool works entirely in the browser with no account required.

Common Use Cases

Calculating a current weighted GPA or course grade mid-semester

Determining what score is needed on a final exam to pass or achieve a desired grade

Verifying that a professor's grade calculation matches your own records

Planning effort allocation across remaining assignments based on their grade impact
