Grade Calculator

Calculate your current course grade from assignment points. Add as many assignments as you need and see the percentage and letter grade instantly.

Your assignments

Equal-weight points

Use points earned and points possible for each assignment. This calculator treats the course as a total-points system.

How to calculate a grade

1. Add each assignment

Enter the points you earned and the total points possible. For example, 42 out of 50 points is entered as 42 and 50.

2. Add all assignments

The calculator adds your earned points and possible points across the list. This is a total-points method, so a 10-point quiz and a 100-point exam affect the result according to their point values.

3. Read the result

Your percentage is the total earned points divided by total possible points, multiplied by 100. The letter grade shown is based on the standard scale displayed below.

Grade % = Total Points Earned ÷ Total Points Possible × 100
Need category weights? Use the Weighted Grade Calculator instead. It is designed for classes where homework, quizzes, exams, or projects have different weights.

Important note about grading scales

Schools and instructors can use different letter-grade boundaries. Our default scale is a common reference, not a universal academic policy.

Frequently asked questions

What is a grade calculator?

A grade calculator turns the points or percentages you earned on assignments, quizzes, and exams into a single course percentage and letter grade, so you don't have to add everything up by hand.

How does a percentage turn into a letter grade?

Once your total percentage is calculated, it's matched against a grading scale — a table of percentage ranges mapped to letters like A, B, C, D, and F. Check the Grading Scale page, since your school or syllabus may set different cutoffs.

Does this calculator work for GPA too?

This tool calculates a single course grade, not a GPA. A GPA combines the grades from multiple courses, usually weighted by credit hours. Convert a percentage to a GPA point value on the Grading Scale page.

What if my class uses total points instead of weighted categories?

This calculator already works on a total-points basis — enter points earned and points possible for each assignment. If your syllabus instead lists percentage weights for categories like homework and exams, use the Weighted Grade Calculator instead.
