Grade Calculator
Calculate your weighted average grade from assignments and their weights. Enter each item as "Grade Weight" per line (e.g. 85 20 for 85% worth 20%). Free online grade calculator for students.
Grade calculator
Format: Grade Weight (e.g. 85 20). Weight as percentage. One per line.
Weighted grade
What is this?
A grade calculator computes weighted average when assignments have different weights. Formula: sum(grade × weight) ÷ sum(weights). Example: 85% (20%) + 90% (30%) + 88% (50%) = 88.1% final. Enter each assignment as "Grade Weight" per line—e.g., "85 20" for 85% worth 20% of the total. Weights can be percentages that add to 100, or the calculator normalizes them. Use it to track your current grade, project your final grade, or work backward to find what you need on an upcoming assignment. Essential for students who want to stay on top of their grades.
When to use
Use to calculate current grade, project final grade, or see what you need on the final. Example: Homework 85 (20%), Midterm 90 (30%), need 88 on Final (50%) for 88% overall. Students track progress throughout the semester. See what score you need to pass or get an A. Plan which assignments to prioritize. Teachers can verify grade calculations. Parents help kids understand their standing. Essential for academic success. Know your numbers before the final.
How to use
Enter one assignment per line: grade (0–100) followed by weight (percentage). Weighted grade = sum(grade × weight) ÷ sum(weights).
Example: 85 20, 90 30, 88 50 → (85×20 + 90×30 + 88×50) ÷ 100 = 88.1%
Frequently asked questions
- Weighted grade = sum(grade × weight) ÷ sum(weights). Each assignment grade is multiplied by its weight (percentage), then divided by total weight.
- The calculator normalizes automatically. Enter weights as percentages (e.g. 20, 30, 50). If they sum to 100, the result is the final grade. Otherwise it's the weighted average.
- Enter each assignment or category with its grade and weight. For example: Homework 85% weight 20, Midterm 90% weight 30, Final 88% weight 50.
