Quickly calculate a grade curve for any set of scores. Whether you're an educator looking to adjust class averages or a student understanding potential grading, this free Grade Curve Calculator simplifies the process. Choose from various curving methods to instantly see adjusted grades.
Formula:
The formula for a simple Grade Curve often involves adding a constant or scaling proportionally:
- Add Fixed Points:
Adjusted Grade = Original Grade + Offset - Scale to Highest:
Adjusted Grade = Original Grade + (Max Possible Score - Highest Original Score) - Scale to Target:
Adjusted Grade = Original Grade + (Target Score - Highest Original Score)
Where:
Original Gradeis the student's initial score.Offsetis the number of points added to each grade.Max Possible Scoreis the maximum achievable score (e.g., 100).Highest Original Scoreis the highest score among all submitted grades before curving.Target Scoreis the desired highest score after curving.
