How to Calculate Your Grade
If you want to know your current average, your weighted grade, or what you need on your final, this guide will show you exactly how to calculate your grade step-by-step.
Many students ask questions like How do I calculate my grade?, How do weighted grades work?, and What do I need on my final? The answer depends on how your class is structured. This page breaks down the most common methods in a simple, practical way.
Method 1: Simple Grade Average
If all assignments are worth the same number of points, you can calculate your grade by adding your scores together and dividing by the total points possible.
Formula:
(Total Points Earned ÷ Total Points Possible) × 100
Example
- Assignment 1: 18/20
- Assignment 2: 42/50
- Assignment 3: 90/100
Total earned = 18 + 42 + 90 = 150
Total possible = 20 + 50 + 100 = 170
Grade = 150 ÷ 170 × 100 = 88.2%

Method 2: Weighted Grade Calculation
Some classes use weighted categories, which means different parts of the class count more than others. For example, tests might be worth more than homework.
Example
- Homework: 92% worth 20%
- Quizzes: 85% worth 30%
- Tests: 88% worth 50%
Weighted grade =
(92 × 0.20) + (85 × 0.30) + (88 × 0.50)
= 18.4 + 25.5 + 44
= 87.9%

Method 3: What You Need on Remaining Work
If you want to know what grade you need on your remaining assignments, projects, or final exam, you can work backward from your target grade.
You need to know:
- Your current grade
- Your target grade
- How much of the class is still left

Method 4: Final Exam Calculation
If your final exam counts as a specific percentage of your class, you can calculate the score you need by using your current grade, your target grade, and the final exam weight.

Method 5: GPA Calculation
GPA is different from a class percentage. GPA converts letter grades into grade points and averages them across all your classes.
- A = 4.0
- B = 3.0
- C = 2.0
- D = 1.0
- F = 0.0
