About this calculator
WeightedGrade is a focused calculator for students, parents, tutors, and teachers who need to understand a percentage-based weighted course grade.
The tool is designed for the common syllabus model where each course category has a weight, such as homework 20%, quizzes 15%, exams 45%, and a final exam 20%. It calculates the current grade from included categories and helps estimate what score is needed on remaining work.
What it is best for
- Checking a weighted average from category scores.
- Planning what grade you need on a final exam.
- Finding whether category weights add to 100%.
- Explaining weighted grading with a simple formula.
What it does not replace
This calculator does not replace your official gradebook, school policy, instructor rules, or syllabus. Some classes use dropped scores, curves, extra credit, late penalties, or custom rounding. If your class uses those rules, adjust the inputs first and compare the result with your official gradebook.
Privacy-first design
