Grade Calculator Online

The grade calculator helps you quickly determine your final course grade using weighted averages. Instead of performing manual calculations, this tool automatically computes results based on percentage or letter grades and their assigned weights.

How to Calculate Your Final Grade

The standard formula for calculating a final grade is:

G = (F × w) + (C × (1 − w))

Where:

G = Final course grade
F = Final exam grade
w = Weight of the final exam (in decimal form)
C = Current course grade before the final exam

Example Calculation

Suppose a student has:

Current grade = 85%
Final exam grade = 92%
Final exam weight = 20% (0.20)

G = (92 × 0.20) + (85 × (1 − 0.20))
G = 18.4 + (85 × 0.80)
G = 18.4 + 68
G = 86.4

Final Grade = 86.4%

How to Use the Grade Calculator

Select your grading format (percentage or letter grade).
Enter each assignment, exam, or course component grade.
Input the corresponding weight for each component.
Click Calculate to view your final result instantly.
