Grade Calculator
Calculate current weighted course averages and determine the exact score needed on your final exam to achieve your target class grade.
About the Grade Calculator
The Grade Calculator features two vital academic modes: a Weighted Grade Calculator for combining assignments, quizzes, midterms, and participation, and a Final Exam Calculator that answers the question: "What score do I need on the final exam to get an A (or pass)?"
Teachers and university professors frequently grade courses using percentages with assigned category weights (such as Homework 20%, Midterms 30%, Final 50%). This calculator automates weighted distribution math so you can plan your study time effectively.
How to Calculate Grade
To calculate current course grade: Enter assignments with scores (%) and their respective category weights (%).
To calculate what you need on the final: Switch to "Final Exam Mode", enter your Current Grade, Target Grade, and Final Exam Weight.
Click Calculate to view your required exam score and whether that score is attainable.
Weighted Grade & Final Exam Formulas
Current Grade = ∑(Assignment Score × Weight) / ∑(Weights) Required Final Score = [Target Grade - (Current Grade × (1 - Final Weight%))] / Final Weight%
Multiply each earned score by its category percentage weight. To find the required final score, isolate the remaining uncompleted weight percentage against your target grade.
Variable Descriptions
- Current Grade
- Average percentage earned on completed coursework
- Target Grade
- The minimum course percentage desired (e.g., 90% for an A, 70% for a C)
- Final Weight
- Percentage of the overall class grade determined by the final exam
Worked Example
Important Considerations & Tips
- If the required final score is over 100%, the target grade is mathematically impossible without extra credit curve points.
- Make sure that all category weights sum up to 100% for full syllabus balance.
- Different colleges apply different grade boundaries; check your syllabus for specific letter cutoffs.
Frequently Asked Questions
How do you calculate a weighted class grade?
Multiply each grade category by its weight percentage in decimal form, add all the resulting products together, and divide by the total weight sum.
What do I do if my weights do not add up to 100%?
The calculator automatically normalizes your entered weights by dividing the total weighted points by the sum of weights entered so far.
How is the final exam score calculated?
Subtract the grade points you have already secured from your target course grade, then divide the remaining points by the final exam’s weight percentage.
