Check your current class grade
Add completed assignments and exams to calculate your total earned percentage before the next gradebook update.
Grade Calculator
Calculate your grade from points or weighted categories, then find the exact score you need on your final exam to reach a target course grade.

Results use the percentages you enter. Letter-grade cutoffs, rounding, dropped assignments, extra credit, and course policies vary, so confirm the result against your syllabus or gradebook.
What Is Grade Calculator?
A grade calculator converts assignment scores, category weights, or a current course average into a clear percentage result. Use the points mode when your class is based on total points, or use the weighted grade calculator when homework, tests, projects, and the final exam contribute different percentages.
The final grade calculator works backward from your desired course grade. It combines your current grade with the percentage assigned to the final exam and calculates the exam score needed to meet your target.
How to Use Grade Calculator
1
Choose a Calculation Mode
Select Points Grade, Weighted Grade, or Final Grade Needed based on how your course is graded.
2
Enter Your Scores
Add earned and possible points, category grades and weights, or your current grade and final exam details.
3
Calculate Your Grade
Run the calculation to see your percentage, weighted contribution, or required final exam score.
4
Check Your Course Policy
Compare the result with your syllabus for rounding, extra credit, dropped assignments, and letter-grade cutoffs.
How the Grade Calculator Works
For a points-based class, the calculator divides total points earned by total points possible. For a weighted class, it multiplies every category grade by that category's decimal weight and adds the contributions.
To calculate the grade needed on a final, the tool subtracts the completed-work contribution from the target course grade and divides the remainder by the final exam weight.
Points grade = earned ÷ possible × 100; weighted grade = Σ(grade × weight) ÷ Σ(weights); required final = [target − current × (1 − final weight)] ÷ final weight
Example
If your current grade is 87%, your target is 90%, and the final is worth 30%, you need 97% on the final: [90 − 87 × 0.70] ÷ 0.30 = 97.
Grade Calculator Features
- Calculates an overall grade from earned and possible points
- Supports weighted categories with different percentage values
- Normalizes partial category weights when they do not total 100%
- Calculates the final exam score needed for a target course grade
- Identifies targets that require more than 100% or are already secured
Common Use Cases
Calculate a weighted final grade
Combine homework, quizzes, projects, midterms, and finals when each category has a different course weight.
Plan for a final exam
Enter your current average, desired course grade, and final exam weight to see the minimum final score you need.
Limits and Important Notes
- The common A–F estimate uses 90/80/70/60 cutoffs, but your school or instructor may use a different grading scale.
- Dropped scores, curved grades, extra credit rules, category caps, and instructor rounding are not applied automatically.
- The final-grade mode assumes the current grade represents all work completed before the final and that no other assignments remain.
- A result above 100% is mathematically correct for the entered target but may be impossible without extra credit.
