Calculate your course grade with weighted categories. Perfect for classes where different assignments have different importance like homework 20%, tests 50%, final 30%.
Enter category grades and weights to calculate
Weighted Grade = Σ(Grade × Weight) ÷ 100
Sum of (each grade multiplied by its weight percentage) divided by 100
Course with three categories:
Result: 83.6% = B grade
A weighted grade means different categories have different importance. For example, if tests are 60% of your grade and homework is 40%, tests are weighted more heavily. A 90% on tests contributes more to your final grade than a 90% on homework.
Yes, ideally weights should sum to 100%. If they don't, you may be missing a category or have incorrect weights. Check your syllabus to ensure you've entered all graded categories with their correct percentages.
Course weights are listed in your syllabus, usually in the grading policy section. They show how much each category (homework, tests, final, etc.) contributes to your final grade. If you can't find them, ask your instructor.
Leave that category blank for now. The calculator will compute your current weighted grade based on completed work. To see what you need on remaining work, use our Final Grade Calculator.
Regular grade treats all work equally. If you have three grades (80%, 90%, 100%), your average is 90%. Weighted grade multiplies each score by its importance. With weights of 20%, 30%, 50%, the same grades give 93%.
Yes, extra credit typically adds to your percentage in a specific category. If you have 85% in homework and earn 5% extra credit, your homework grade becomes 90%, which then gets weighted according to the category weight.
If your instructor drops the lowest test score, calculate your test average without that score before entering it. For example, if you have three tests (70%, 85%, 90%) and the lowest is dropped, enter 87.5% (average of 85% and 90%).
If weights are given as ratios (like 2:3:5), convert to percentages. Add them up (2+3+5=10), then divide each by the total: 2/10=20%, 3/10=30%, 5/10=50%. Enter these percentages in the calculator.
Weighted grading systems recognize that different types of work require different levels of effort and demonstrate different levels of mastery. A comprehensive final exam that tests all course material naturally deserves more weight than a single homework assignment.
When instructors design weighted grading systems, they typically assign larger weights to assessments that better demonstrate overall understanding, like major exams and projects, while giving smaller weights to practice work like homework and participation.
