Online Average Grading Calculator: Easily Calculate Percentages, Letter Grades, and Grade Points
Grading Calculator — A widely used tool widely used to get the best results in finding the grades for students, teachers, and parents. It offers grading systems, and supports them, for percentages, letters, and points, meaning it is an all-in-one package. Let’s look at how this tool works, what formulas it uses, and practical examples of each type of grading.
How Does a Grading Calculator Work?
Most of the time, there are three sections/tabs in the grading calculator for different grading systems:
- Percentage-Based Grading
- Letter-Based Grading
- Points-Based Grading
Each section features adjustable inputs where grades and weights are entered along with a reset button to remove or adjust the data. Below is how their respective formulas break down, and examples of what it means for each grading system.
1. Percentage-Based Grading
This approach has the grades averaged per percentages and their discrete weights.
Formula:
Example:
You have:
- Assignment 1: 85% (weighted at 40%).
- Assignment 2: 90% (weighted at 60%).
Calculation:
Result: The final grading is 88%.
2. Letter-Based Grading
You assign number equivalents to letter grades (for example, A = 95, B = 85), weight the courses, and average.
Letter to Percentage Conversion Table (example mapping):
- A+ = 100
- A = 95
- A- = 90
- B+ = 89
- B = 85
- B- = 80
Formula:
Example:
You have:
- Assignment 1: A (95) (weighted at 50%).
- Assignment 2: B (85) (weighted at 50%).
Calculation:
Result: The final grading is 90% (A-).
3. Points-Based Grading
So, if the assignments are weighted, this method gives you a grading earned/total possible points.
Formula:
Example:
You have:
- Quiz 1: Scored 45 out of 50 (weighted at 30%).
- Quiz 2: Scored 80 out of 100 (weighted at 70%).
Step 1: Convert Points to Percentage:
- Quiz 1: 45/50 X 100 = 90%
- Quiz 2: 80/100 X 100 = 80%
Step 2: Apply Weights:
Result: The final grading is 83% (B).
