A weighted grade is calculated by multiplying each category score by its weight percentage and summing the results. Formula: Total Grade = (Score1 * Weight1) + (Score2 * Weight2) + ... For example, if a Midterm contributes 40% and a Final 60%, and you score 80 and 90, your grade is (80*0.4) + (90*0.6) = 86.

Know exactly what score you need on your final to reach your target grade.

Formula

Weighted Grade = Sum(Score_i * Weight_i) / Sum(Weights). Ensure all weights add up to 100%.

How It Works

List your assignments or categories (e.g., Midterm, Projects).
Enter the weight for each (ensure they total towards 100%).
Input your scores for each category.
Set a target grade to see what you need on the final exam.

Formula:

Final Grade = (Score1 * Weight1 + Score2 * Weight2 + ...) / 100

Examples

Homework (20%) at 90, Midterm (30%) at 80, Final (50%) at 85.

Result: Total: (18) + (24) + (42.5) = 84.5%.

You have 40% of the grade at 90, and want an A (93%). What do you need on the remaining 60%?

Result: You need a 95% average on the remaining components.

Frequently Asked Questions

What if weights don't add up to 100%?

The calculator will normalize your current grade based on the weight you have entered so far, but the "needed score" works best when target and remaining components complete the 100% scale.

Can I use this for GPA?

Yes, if you use the 4.0 scale points instead of percentages for the "score".

How to handle extra credit?

If extra credit adds more than 100% weight, your grade may exceed 100. If it just adds points to a category, increase that category score.

Key facts

Weighted grading accounts for the relative importance of different course components. Common categories include Homework (10-20%), Quizzes (10-20%), Midterm (25%), and Final (35-40%). To find the required final exam score: Final Needed = (Target - CurrentWeighted) / FinalWeight. Academic performance tracking reduces test anxiety by providing clear mathematical goals.

Trend & Behavior Analysis

The Final Exam (typically high weight) acts as a high-leverage point. A small 10% improvement on a final worth 40% of the grade improves the overall course grade by 4 points—more than double the impact of a similar improvement on a 15% midterm.
