Grade Calculator
Weighted Grade Calculator for weighted categories, assignment weights, and weighted course averages. The tool normalizes the weights you enter, runs in your browser, and does not upload grades.
What this means: The calculator normalizes the weights you entered. If your weights add to 80 instead of 100, it still returns the average for the 80% of graded work represented here.
How it works
- Enter each graded category or assignment, such as homework, quizzes, exams, or projects.
- Type the grade as a percentage and the category weight as a percentage.
- The calculator multiplies each grade by its weight, adds the weighted points, then divides by the total weight entered.
- If your weights do not add to 100 yet, the result shows the average for the graded work represented by those weights.
Example calculation
If homework is 92 at 30%, quizzes are 84 at 20%, and exams are 88 at 50%, the weighted grade is (92 x 30 + 84 x 20 + 88 x 50) / 100 = 88.4%.
Calculate grades by weight
Use this page when a syllabus or gradebook gives different weights to homework, quizzes, exams, projects, participation, or individual assignments. Enter each category grade as a percentage, then enter the category weight or assignment weight.
The calculator uses normalized weights. That means weights do not have to total exactly 100 in this mode. For example, weights of 30, 20, and 50 produce the same weighted course average as weights of 3, 2, and 5 because the relative weight of each row is the same.
If you only know earned points and possible points, convert those raw points to a percentage first with the Percentage Grade Calculator. Then return here and enter that percentage as the category grade before applying the category weight.
What this means
This is your estimated course average for the categories you entered. It is useful for planning, but your official gradebook may include rounding rules, dropped scores, curves, late penalties, or extra credit.
FAQ
- Is this a weighted grade calculator?
- Yes. This page calculates a weighted course grade from category scores or assignment scores and their weights.
- Do weights have to add up to 100?
- No. In normalize mode, the calculator uses the relative weights you enter. Weights of 30, 20, and 50 return the same result as 3, 2, and 5.
- Can I use assignments instead of categories?
- Yes. Use each assignment as a row and enter its grade percentage and assignment weight. Use categories when your gradebook groups work such as homework, quizzes, and exams.
- What if I only know points earned and points possible?
- Use the Percentage Grade Calculator first to convert earned points and possible points into a percentage. Then enter that percentage here as the category or assignment grade.
- Does this calculate the final exam score I need?
- Use the final grade calculator or final exam calculator for that question. This page estimates the current weighted grade.
- Is this official gradebook math?
- No. This is a browser-local estimate. Official gradebooks may apply rounding, dropped scores, curves, late penalties, extra credit, or school-specific rules.
