How to Calculate Weighted Grades
Most college and high school classes use a "weighted" system where exams are worth more than homework. Here is how the math works.
Identify Categories
Look at your syllabus. Example: Homework (20%), Quizzes (30%), Midterm (20%), Final (30%).
Average Each
Calculate your average score for each category. (e.g., if you got 90, 80, 100 on HW, your HW average is 90).
Multiply & Sum
Multiply each average by its weight (90 × 0.20 = 18 points). Sum these up to get your final class grade.
Common Grading Scales
The "Do or Die" Final Exam
If your final is worth 40%, it is mathematically impossible to get an A if your current grade is below 83.3%. Know your limits.
Calculate your "minimum to pass" score. It is often much lower than you think, reducing anxiety.
Always input extra credit as a separate row with 0 weight (if it's pure bonus points) or add it to an existing category numerator.
GPA vs. Weighted Percentage
Weighted Grade
This is your raw score (0-100) for a specific class. It determines the Letter Grade you receive on your transcript.
GPA
Grade Point Average converts that letter into a scale (0.0 to 4.0). It averages all your classes together for college admissions.
AP/Honors
Some schools use a 5.0 scale for AP classes. This calculator uses the standard unweighted 4.0 scale for simplicity.
