How to Use the Grade Curve Calculator

This calculator helps to adjust your score as if the highest score in the class represents a perfect score of 100%. Simply enter the highest score someone achieved in the class, then enter your own score. Click “Calculate” to see your curved grade.

How It Calculates

The calculator computes the curved grade by dividing your score by the highest score in the class and then multiplying by 100. That gives you a percentage which implies your performance as if the top score is the maximum possible score.

Limitations

Please note that this calculator assumes linear scaling and that the top score is the ideal score of 100%. It may not accurately reflect grading policies that use different scaling methods or incorporate other factors like participation, attendance, or extra credit.
