Average Grade Calculator

What Is an Average Grade Calculator?

An Average Grade Calculator helps you find the average percentage of several grades. It is useful when you want to quickly combine grades from tests, quizzes, assignments, or other coursework and see your overall average.

For example, if your grades are 80%, 90%, 70%, and 100%, the calculator adds the grades together and divides the total by the number of grades. Your average grade would be 85%.

This calculator works when each grade has the same importance or weight.

How to Calculate Your Average Grade

To calculate an average grade manually:

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

For example, if your grades are:

• 80%
• 90%
• 70%
• 100%

The calculation is:

80 + 90 + 70 + 100 = 340

There are 4 grades, so:

340 ÷ 4 = 85%

Your average grade is therefore 85%.

How to Use the Average Grade Calculator

Using the calculator is simple:

1. Enter your first grade as a percentage.
2. Enter your other grades in the available fields.
3. Click + Add Another Grade if you need more grade fields.
4. Enter each grade you want to include.
5. Click Calculate Average Grade.

The calculator will show your average percentage and the number of grades included in the calculation.

Average Grade Formula

The standard average grade formula is:

Average Grade = Sum of All Grades ÷ Number of Grades

For example:

(85 + 90 + 78 + 92) ÷ 4 = 86.25%

This calculation assumes that all grades have equal weight.

Example of an Average Grade Calculation

Suppose you received the following grades:

• Test 1: 85%
• Test 2: 90%
• Assignment: 78%
• Quiz: 92%

First, add the grades:

85 + 90 + 78 + 92 = 345

Then divide by the number of grades:

345 ÷ 4 = 86.25%

Your average grade is 86.25%.

What If My Grades Have Different Weights?

If your assignments, tests, quizzes, or exams have different weights, a simple average may not accurately represent your course grade.

For example, a final exam worth 40% of your course grade has a much greater effect on your overall grade than a quiz worth 5%.

In that situation, you should use a weighted grade calculation instead of a simple average.

Our Average Grade Calculator is designed for calculating the standard average of percentage grades where each grade is treated equally.
