Weighted Grade Calculator
Calculate your final course grade using weighted categories. See your current grade and find out what you need on remaining work.
Most courses weight different components differently — your final exam might count for 40% while homework only counts for 20%. A simple average would give you the wrong answer. This weighted grade calculator accounts for each category's importance and tells you exactly where you stand, plus what you need on remaining work to hit your target grade.

Frequently Asked Questions
What is a weighted grade calculator?
A weighted grade calculator computes your final course grade based on the relative importance (weight) of each assignment category. For example, if homework counts for 20%, quizzes 15%, midterm 25%, and final exam 40%, your grade is not a simple average — each category contributes proportionally to its weight.
How do I calculate my weighted grade?
For each category, divide your score by the maximum possible score to get a percentage, then multiply by the category weight. Sum these weighted scores across all completed categories. Divide by the total completed weight to get your current grade. Our calculator handles all of this automatically.
Do my weights need to add up to 100%?
Yes — your weights should total 100% for the result to be accurate. The calculator shows a running weight total with a green check when you reach exactly 100%. If some categories are not yet graded, leave the score blank and the calculator will compute your grade based only on completed work.
What does "leave score blank" mean?
If a category has not been graded yet — for example your final exam is still upcoming — leave the score field empty. The calculator will compute your current grade from only the categories you have entered scores for, and tell you how much of your total grade that represents.
How do I find out what I need on my final exam?
After calculating your current grade, enter your target final grade in the "What do I need on remaining work?" section and click Calculate. The tool will tell you what average score you need across all remaining (unscored) categories to hit your target.
Can I add custom categories?
Yes — click "+ Add category" to add any category your course uses, such as labs, participation, projects, or extra credit. Name it anything you like and set its weight.
