How do I calculate my grade average?
Calculate your weighted grade average from major tests and quizzes – fast and easy to follow.
When assignments have different weights, a weighted average gives a more useful result than a simple average.
How the calculation works
- Enter the grades.
- Set the weight for each grade.
- The calculator multiplies grade and weight.
- The sum is divided by the total weight.
The calculation is the sum of grade × weight divided by the total weight. Your school rules remain decisive.
Calculator
Enter grades and weights. Empty rows are ignored.
Example: Example: grade 2 with weight 2 and grade 3 with weight 1 produce an average of 2.33.
Pro tips
- Major tests often count double compared to quizzes – check your school's weighting rules.
- For point-based grading systems (e.g. 0-15), convert to your local grade scale first.
Frequently Asked Questions
How do you calculate a weighted grade average?
Each grade is multiplied by its weight, the results are added up, and the sum is divided by the total of all weights.
What's the difference between a simple and a weighted average?
In a simple average every grade counts equally; in a weighted average, e.g. major tests count more than oral grades.
How can I calculate the grade I need?
Enter your existing grades and try different values for the missing grade to see what final average results.
Do oral grades count less than written tests?
It depends on the school system and subject – written grades like major tests often carry more weight, which you can reflect using the weighting in the calculator.
