Grade Calculation Formula
The calculator uses standard academic formulas to determine your final percentage and grade.
Total Marks Obtained = Sum of Marks in All Subjects
Total Maximum Marks = Number of Subjects × Maximum Marks Per Subject
Percentage = (Total Marks Obtained ÷ Total Maximum Marks) × 100
The calculated percentage is then matched against the grading scale to determine the appropriate letter grade and academic performance level.

Example Calculation
Suppose a student has five subjects with a maximum of 100 marks each and obtains scores of 92, 85, 78, 88, and 81. The calculator first adds the obtained marks to determine the total score. It then calculates the percentage by dividing the total obtained marks by the total maximum marks and multiplying the result by 100. Finally, the corresponding letter grade and performance level are displayed instantly.
Because calculations update automatically, students can experiment with different marks to understand how improvements in individual subjects affect their final percentage and grade.
