How to Use the Percentage Calculator

Enter your current grade percentage in the course
Set the weight of your current work (e.g., 70% for assignments, quizzes, etc.)
Set the weight of your final exam (e.g., 30%)
Enter your desired final grade percentage
The calculator will show you exactly what score you need on the final exam

Understanding the Calculation

This calculator uses the weighted average formula to determine what you need on your final exam:

Required Final Score = (Desired Grade - (Current Grade × Current Weight)) ÷ Final Weight × 100

Example Calculation

If you have:

Current Grade: 80%
Current Work Weight: 70%
Final Exam Weight: 30%
Desired Final Grade: 85%

Required Final Score = (85 - (80 × 0.70)) ÷ 0.30 × 100 = (85 - 56) ÷ 0.30 × 100 = 96.7%

Important Notes

Make sure your current work weight and final exam weight add up to 100%
If the required score is over 100%, your target grade may not be achievable
If the required score is negative, you've already achieved your desired grade
