Weighted Grade Calculator
What Is a Weighted Grade Calculator?
This tool calculates your final grade when different categories of work - homework, quizzes, tests, final exams - each count for a different percentage of your total grade. See our full guide to weighted grade calculation for the underlying formula.
For Any Weighted Grading System
Useful whenever your syllabus lists category weights instead of a simple point total - which describes most high school and college courses.
How to Use This Calculator
Find your category weights
Check your syllabus for the percentage each category (homework, tests, etc.) counts toward your total grade.

Tips & Tricks
- Always double check that your category weights add up to exactly 100% - the tool will flag it if they don't, but it's worth confirming against your syllabus too.
- Recalculate your category averages (not just guess them) before entering them here for the most accurate final result.
- If one category is dragging your grade down significantly, that's usually your highest-leverage place to focus study time.
- See our full guide for a worked example if the concept still feels confusing.
Frequently Asked Questions
What if my category weights don't add up to 100%?
Double-check your syllabus - if weights genuinely don't total 100%, ask your instructor for clarification, since this usually indicates a transcription error.
How do I find my average score within a category?
Average all your scores within that category first (e.g., all homework grades), then enter that average here.
Can I add more than four categories?
Yes, click 'Add Category' as many times as needed to match your syllabus.
What's the formula behind this calculator?
Final Grade = the sum of (each category's average × its weight). See our full guide for a worked example.
Does this work for college and high school classes equally?
Yes, the weighted formula is identical regardless of grade level.
Can I use this to predict my final grade before all assignments are in?
Yes - enter your current averages, and update them as new grades come in throughout the term.
What if a category has no weight listed?
Check with your instructor - every graded category should have a defined weight that contributes to your final grade.
Is this different from a simple average?
Yes significantly - a simple average treats every assignment equally, while weighted grading respects your syllabus's category importance.
Can this handle extra credit?
Include extra credit within the relevant category's average score before entering it.
