Final Grade Calculator
Your final course grade from a hypothetical exam score.
Quick answer
- Formula: Final grade = Current × (1 − exam weight) + Exam score × exam weight
- Worked example — Final course grade: 86.50% (full example below).
Final Grade Calculator
| Final course grade | 86.50% |
| Letter grade | B |
A current 85% with a 90% on a final worth 30% finishes at 86.5% — a B on the standard scale used here.
This calculator works forwards instead of backwards: enter your current grade, the weight of the final exam, and a score you might get on it, and see exactly what your final course grade would be.
Try a few exam scores — a realistic one, a best case and a worst case — to see the range of final grades still possible before you sit the exam.

Frequently asked questions
How is this different from the Grade Calculator?
The Grade Calculator solves backwards for the exam score a target requires. This one computes forwards: you supply an exam score and it returns the resulting final grade.
Which letter-grade scale is used?
The common scale A ≥ 90%, B ≥ 80%, C ≥ 70%, D ≥ 60%, F below 60%. Your school may use plus/minus or a different cutoff, so treat the letter as a guide.
