How to Use the Grade Calculator
Our grade calculator helps students determine their letter grade from a percentage, compute weighted averages for multiple assignments, and find out what score is needed on a final exam to achieve a target overall grade.
Grading Scale

Weighted Grade Formula
Weighted Grade = Σ (Assignment Grade × Weight) / Σ Weights. All weights should sum to 100% for accurate percentage. Our tool calculates the weighted average even if weights don't sum to 100%.
Final Exam Score Formula
Required Final Score = (Desired Grade − Current Grade × (1 − Final Weight)) / Final Weight, where weights are in decimal form (e.g., 25% = 0.25).
