Grade Average Calculator
Calculate an unweighted or weighted grade average from assignment, quiz, exam, or category scores.
Use unweighted for equal items, or weighted when each item/category has a weight.
Enter the score as a percentage from 0 to 100.

Introduction
The Grade Average Calculator estimates a current grade from percentage scores using either equal weighting or custom weights.
For an unweighted average, add the scores and divide by the number of scores. For a weighted average, multiply each score by its weight, add the weighted points, and divide by the total weight.
Formula and method guide
Unweighted average
Average = sum(scores) / number of scores
Use this when every assignment or exam should count the same.
Weighted average
Average = sum(score x weight) / sum(weights)
Use this when exams, homework, quizzes, or projects count differently.
Letter estimate
A >= 90, B >= 80, C >= 70, D >= 60
Use this only as a quick interpretation, not as an official grade.
Variables
A grade entered as a percentage from 0 to 100.
The relative importance of a score or category.
The sum of all weights included in the calculation.
A score multiplied by its weight.
Controls whether weights are used or every score counts equally.
