Final Grade Calculator
Enter your current grade, the final exam's weight, and your final exam score. We compute the weighted average that will appear as your final course grade — and translate it to a letter grade.
Your course grade right now, before the final. · e.g. 86.4
How much of the course grade the final is worth. · e.g. 30
Your percentage on the final exam itself. · e.g. 92
Letter grade · B+
88.08%
+1.68 pts vs. before the final
Examples
B+ entering, 30% final, 92 on the final
= 88.08% (B+)
C entering, 25% final, 80 on the final
= 76.25% (C)
A− entering, 20% final, 100 on the final
= 92.80% (A−)
How it works
Your final course grade is a weighted average of two things: the grade you walked into the final with, and the grade you got on the final itself.
Final course grade · current × (1 − weight) + final × weight
weight is the final exam's share of the course grade, expressed as a decimal — so a 30% final contributes 0.30.
Frequently asked questions
A final grade calculator combines your current course grade with your final exam score, weighted by how much the final is worth, to give you the grade that will land on your transcript.
Use whatever your course portal (Canvas, Blackboard, PowerSchool, etc.) shows as your current weighted average — but make sure the final exam itself is not yet included in that number.
Check your syllabus. Final exams are commonly worth 15–35% of the course grade. If your final is not weighted (just one assignment among many), use the weighted grade calculator instead.
Use percentages. Convert your current letter grade to its midpoint percentage if needed (A = 95, A− = 91, B+ = 88, B = 85, etc.).
