Weighted Grade Calculator
Determine your Class Average accurately
How Weighted Grading Works?
Formula Logic
Unlike basic averages, weighted grades multiply your score by the importance of the task. Final = (G1×W1 + G2×W2) / Total W
Student Focused
Designed for easy mobile entry. Input fields automatically adjust to your screen size for quick grade checking in class.
Flexible Calc
Didn't finish the course yet? No problem. The tool only calculates based on the weights you have entered so far.
Take Control of Your Semester Grade
Your Final Class Grade isn't a mystery—it's a math problem. Assignments, Quizzes, and Finals carry different values. Our Weighted Grade Calculator merges them instantly into one clear percentage.
Accurate Coursework
In many US/UK universities, Homework might only be 10%, while the Final Exam is 50%. Simple averaging gives the wrong answer. This tool uses the correct "Weighted Percentage" logic.
Goal Planning
Use the tool backward: Input your current grades and a hypothetical score for your upcoming Final. See if scoring a 90% helps you cross the borderline from a B+ to an A.
Letter Grade Preview
Stop calculating manual decimals. The tool auto-converts your percentage (e.g. 93.5%) into standard GPA letter grades (A/A-/B+) based on global norms.
Your Ultimate Guide: How to Calculate Weighted Grade?
Use this weighted grade calculator to calculate your final grade based on category weights like homework, quizzes, projects, midterms, and finals. If your course uses a weighted grading system, this weighted average grade calculator helps you get accurate results instantly—fast, simple, and mobile-friendly.
What Is a Weighted Grade?
A weighted grade means each category of work (like homework, tests, and the final exam) does not count equally. Instead, each category has a weight (percentage of your final grade).
For example:
- Homework = 20%
- Quizzes = 10%
- Midterm = 30%
- Final Exam = 40%
Why Accuracy Matters?
In this system, the final exam matters much more than quizzes. That’s why a specialized weighted grade calculator is more accurate than a simple average calculator.
Using our tool helps you understand your standing before the semester ends.
Weighted Grade Formula
A standard weighted grade calculator follows this universal mathematical formula:
Where:
- Score is your percentage score in that category
- Weight is how much that category contributes to the final grade
Homework: 80% (20%) | Midterm: 70% (30%) | Final: 90% (50%)
Final Grade = (80×0.20) + (70×0.30) + (90×0.50)
= 16 + 21 + 45 = 82%
How to Use This Weighted Grade Calculator
To use the calculate weighted grade tool correctly, follow these simple steps:
- Add categories (Homework, Quiz, Project, Midterm, Final).
- Enter each category’s weight (e.g., 20, 10, 30, 40).
- Enter your score for each category (percentage).
- Click Calculate to see your result instantly.
✅ Tip: The weights should usually add up to 100%. If they don’t, your teacher may be using a partial grading scheme (explained below).
Weighted Grade Calculator Examples (Most Important)
Example 1: Typical course
Homework: 85% (20%) | Quizzes: 75% (10%) | Midterm: 68% (30%) | Final: 80% (40%)
Final Grade = (85×0.20) + (75×0.10) + (68×0.30) + (80×0.40)
= 17 + 7.5 + 20.4 + 32 = 76.9%
A reliable weighted grade calculator saves you from doing this tedious math manually.
Example 2: Only some categories graded so far
Sometimes your final exam hasn’t happened yet. In that case, you can calculate weighted grade using graded categories only (Running Average).
Homework: 90% (20%) | Quizzes: 80% (10%) | Midterm: 70% (30%) | (Final not taken yet)
Current Grade (so far) = (1800 + 800 + 2100) ÷ (20+10+30) = 4700 ÷ 60 = 78.33%
This is exactly what a good weighted average grade calculator should show.
What Score Do I Need on the Final? (High-Value)
This is one of the most searched questions. Use this logic as a manual what do I need on the final calculator.
Method (simple):
If you know your target final grade, you can solve for the required final exam score:
Example Scenario:
Weights: Homework 20%, Quizzes 10%, Midterm 30%, Final 40%
Current scores: Homework 85%, Quizzes 75%, Midterm 68%
Current contribution (without final) = (85×0.20) + (75×0.10) + (68×0.30) = 17 + 7.5 + 20.4 = 44.9
Target final grade = 75% | Final weight = 0.40
Required final score = (75 − 44.9) ÷ 0.40 = 75.25%
So you need about 75% on the final to end with 75%. A strong final grade calculator with weights makes this planning easy.
Weighted Grade vs Simple Average
- Simple Average treats everything equally.
- Weighted Grade treats categories based on importance (weights).
If your class uses weights, always use a weighted grade calculator—a simple average calculation can be very wrong and misleading.
Common Mistakes Students Make (Avoid These)
1) Sum ≠ 100%
If weights add to 90% or 110%, results become confusing. Most classes use 100%. Always confirm your syllabus.
2) Points vs Percent
If homework is out of 200 points, convert it to a percentage first (or use a calculate weighted grade tool that supports raw points).
3) Dropped Scores
Some teachers drop the lowest quiz. Your weighted grade calculator won’t know this unless you remove that score manually.
4) Early Rounding
Don’t round each category. Calculate first, then round the final result for better precision.

Frequently Asked Questions
1) Do weights always add up to 100?
Usually yes. But some courses show weights differently until the final exam. If unsure, use the tool to "calculate weighted grade" based on completed weights only (Current Standing).
2) Can I calculate letter grades?
Yes. Convert your final percentage using your course grading scale (A, B, C…) after getting the numerical result from the weighted grade calculator. Many schools differ in grading cutoffs.
3) What if my teacher drops the lowest assignment?
Remove the dropped assignment from the category average yourself, then re-calculate using the weighted average grade calculator logic.
4) Is weighted grading used in college?
Yes—very common in universities, especially engineering, business, and online courses.
5) Can this calculator work for any subject?
Yes. Any course using category weights (Assignments, Labs, Theory) can be calculated accurately with a standard weighted grade calculator.
Short Disclaimer: This weighted grade calculator provides an estimate based on the category scores and weights you enter. Always confirm your course grading policy and rounding rules with your institution.
