How to Calculate a Weighted Grade
A weighted grade gives each assignment a different slice of your final mark. Multiply each score by its weight, add the results, and divide by the total weight:
Weighted grade = (Score₁ × Weight₁ + Score₂ × Weight₂ + …) / Total weightExample:Homework 95% (weight 20%) and Tests 80% (weight 40%) give (95 × 0.20) + (80 × 0.40) = 19 + 32 = 51 points. Over the 60% of the course graded so far, that's a 85% weighted grade.
Percentage Weights vs. Points-Based Grading
Percentage weights are syllabus categories — Tests 40%, Homework 20%, Participation 10%, Final 30%. Points-based classes instead total raw points: a 100-point exam, a 20-point quiz, a 50-point project. Both are weighted grading; the calculator switches between them with one toggle, so match whichever your gradebook shows.
The Weighted Final Exam Formula
Required final = (Target × Total weight − Weighted points earned) / Final weightExample:you've earned 62.6 weighted points, the final is worth 30%, and you want a 90%: (90 − 62.6) / 30 = 91.3% needed on the final. The solver above runs this live for every row you enter — no need to average categories by hand first. If you only know your current grade as a single number, the final grade calculator solves the same question from that starting point, and the weighted gradebook calculator is built for syllabus category averages.
Common Grading Weights
| Category | Typical Weight Range |
|---|---|
| Homework | 10-20% |
| Quizzes | 10-20% |
| Tests/Exams | 30-50% |
| Final Exam | 15-30% |
| Projects | 10-25% |
| Participation | 5-15% |
Frequently Asked Questions
Multiply each assignment score by its weight (as a decimal), add those products together, and divide by the total weight you’ve entered. For example, Homework 95% × 0.20 = 19 and Tests 80% × 0.40 = 32, so your weighted grade over those 60% of the course is (19 + 32) / 0.60 = 85%. This calculator does it live as you type and normalizes automatically when your weights don’t total 100%.
Use the formula: Required = (Target × Total Weight − Points Already Earned) / Final Weight. If you’ve earned 62.6 weighted points, your final is worth 30%, and you want a 90%, you need (90 − 62.6) / 30 = 91.3% on the final. The solver above runs this against every assignment row you enter and shows A, B, C, and D scenarios at once.
The calculator still works: it normalizes your grade to the weights you’ve entered and flags the total in yellow so you know. Early in a semester many gradebooks only count graded categories, so a partial total is normal — but double-check your syllabus, because a typo’d weight is the most common cause of a grade that looks wrong.
If your syllabus says things like "Tests 40%, Homework 20%, Final 30%", use Percentage weights. If your gradebook (Canvas, Blackboard, Google Classroom) instead shows point values per assignment — a 100-point test, a 20-point quiz — switch to Points based and enter earned vs. possible points. Both modes produce the same live weighted grade and final-exam solver.
