What is a Grade Calculator?

This tool calculates your overall grade as a percentage and letter grade. It supports two modes:

Points mode: Enter earned points and total possible points
Weighted mode: Enter multiple scored items each with a weight percentage

Grading scale

B	80% – 89%
C	70% – 79%
D	60% – 69%
F	Below 60%

How to use this tool

Points mode: Enter your earned points (e.g. 87) and the total points possible (e.g. 100).

Weighted mode: Add each graded item (quiz, exam, homework), enter your score (0–100%), and assign each item a weight percentage. The tool calculates the weighted average.

Example use cases

Exam: Scored 42 out of 50 points → 84% → B
Course grade: Homework (30%), midterm (30%), final (40%) → weighted final grade
