What Is an Average Grade Calculator?

An average grade calculator helps you find the simple arithmetic average of multiple grades or scores. It adds all the values together and divides by the number of values. This tool is perfect when you have several equal-weight grades—such as tests, quizzes, or assignment scores—and want to know your overall average.

Unlike a weighted grade calculator, this tool treats every grade equally. Just enter your scores and the calculator does the rest instantly.

How to Calculate an Average Grade

Calculating an average grade by hand is simple. Follow these steps:

  1. Add all your grades together.
  2. Count the number of grades.
  3. Divide the total by the number of grades.

Example:

Grades: 85 + 90 + 95 = 270

Number of grades: 3

Average: 270 ÷ 3 = 90

The calculator above does this automatically the moment you change any value.

Average Grade Formula

The mathematical formula for calculating a simple average is:

Average = Total of all grades ÷ Number of grades

This formula assumes every grade carries equal weight. If your grades have different levels of importance—for example, a final exam worth 40% and quizzes worth 20% each—use the Weighted Grade Calculator instead.

How to Use This Average Grade Calculator

  1. Enter your grades into the input fields.
  2. Add more rows if you have additional grades.
  3. The average updates automatically as you type, or you can click Calculate Average.
  4. Use Copy Result to save or share your average.
  5. Click Reset to restore the default example values.

You can enter whole numbers or decimals. The calculator works with any numeric grading scale—100-point, 4.0, 10-point, 20-point, or any consistent scale.

Average Grade vs. Weighted Grade

An average grade gives every grade equal importance. For example, scores of 80, 90, and 100 each contribute equally to the overall average.

A weighted grade, however, assigns different levels of importance to different assignments or categories. If your final exam counts for 40% of your grade while quizzes count for 20% each, a simple average would be inaccurate. Use the Weighted Grade Calculator for that scenario.

If you're trying to figure out what score you need on a future assessment to reach a target grade, use the Final Grade Calculator.
