Taking Control of Your Grades
"What do I need on the final to keep my A?" is the most common question during finals week. Whether you are in high school or college, understanding how your grade is calculated is the first step to academic success.
Most courses use a Weighted Grading System. This means a homework assignment worth 10% affects your grade differently than a midterm worth 30%. Our calculator handles this complex math for you, allowing you to run "what-if" scenarios and plan your study time effectively.
Key Features

Weighted & Unweighted
Supports percentage-based weights (Categories) and simple points-based grading.
Dynamic Calculation
Your grade updates instantly as you type assignments. No page reloads needed.
Letter Grade Scale
See the corresponding letter grade (A, B+, C-) alongside your percentage.
How to Calculate Your Grade
Using the calculator is straightforward. Grab your syllabus and follow these 3 steps:
Enter Assignments
Input your grades for completed categories like Homework, Quizzes, and Midterms.
Add Weights
Enter the "Weight" percentage for each category from your syllabus (e.g., Homework = 20%).
Check Final Exam
Scroll down to the "Final Exam" section. Enter the weight of your final to see the required score.
Understanding Weighted Grades
The Syllabus Secret: Always check your syllabus first. If "Participation" is worth 10% and you skip class, you are capping your maximum possible grade at 90% (an A- at best) before you even take a test.
How the Math Works
A weighted grade is calculated by multiplying the average grade of a category by its weight, and then summing up these products.
Example:
Homework (20% weight): You have a 95 avg.
Tests (40% weight): You have an 80 avg.
Final (40% weight): Not taken yet.
Current Calculation: (95 × 0.20) + (80 × 0.40) = 19 + 32 = 51 points accumulated so far out of the 60% completed.
