Grade Average Calculator

To calculate your grade average, add up all your grades and divide by the number of grades. For example, if your grades are 85, 90, and 78, the average is (85 + 90 + 78) / 3 = 84.3%.

A simple average treats all grades equally, while a weighted average assigns different importance to each grade. For example, if tests count more than homework, you'd use a weighted average.

Check your syllabus. If your teacher assigns different weights to categories (like tests, homework, quizzes), use the weighted grade calculator. If all assignments count equally, use this simple average calculator.

You need at least one grade, but the average becomes more meaningful with more data points. Typically, teachers have 10-20+ grades by the end of a semester.

Yes, if your extra credit is given as a grade (like 105% on an assignment), include it in your average calculation. This may push your average above 100%.
