Frequently Asked Questions
How do I calculate my weighted grade?
Enter each assignment or category with its score (percentage) and weight. The calculator multiplies each score by its weight, sums the results, and divides by total weight. For example: if homework (30% weight) is 90% and exams (70% weight) is 80%, your weighted grade is (90×0.3 + 80×0.7) = 83%.
How do I find out what I need on the final?
Click the 'Final Exam' tab. Enter your current grade, the weight of the final exam, and your target grade. The calculator shows exactly what percentage you need on the final to achieve your goal.
What grading scales are supported?
The standard US letter grade scale (A+ through F) with plus/minus variants is included. A letter grade reference table is shown so you can easily convert between letters and percentages.
Can I save my grades?
Yes. Your grades are automatically saved in your browser's local storage. They'll be there when you come back — no account needed.
