Final Grade Calculator
Predict where you'll land. Enter your current grade, the final's weight, and the score you expect on the final — the Final Grade Calculator projects your overall course grade and its letter equivalent, so there are no surprises on results day.
Predicted final grade
79.2%
Letter grade: C+
How it works
- Enter your current grade as a percentage.
- Enter the final exam's weight in the course.
- Enter the score you expect on the final (or try a few scenarios).
- The calculator combines them: current × (1 − w) + expected × w.
- Adjust the expected score to see how each scenario changes your final grade.
The formula
Predicted final grade
final = current × (1 − w) + expected final score × w
The weighted combination of everything so far and the final. Try different expected scores to find the boundary between letter grades.
Worked example
Worked example
- Current grade: 82% · Final weight: 40% · Expected final score: 75%
- w = 0.40 → final = 82 × 0.60 + 75 × 0.40
- final = 49.2 + 30 = 79.2
Predicted final grade: 79.2% — a B+ even if the final goes below your current average.
Common mistakes
- Treating the final as if it replaces your current grade instead of being weighted.
- Only planning for your best case — run the numbers for a worst-case score too.
- Forgetting that the final's weight is out of the remaining 100%, not added on top.
Frequently asked questions
What's the difference between this and the required grade calculator?
This one predicts: given an expected final score, what will my grade be? The required grade calculator works backwards: given a target grade, what score do I need? They're two sides of the same equation.
Can I model multiple scenarios?
Yes — just change the expected final score. The result updates instantly, so you can compare a safe score, a stretch score, and a worst case.
What if the final has multiple parts?
Combine the parts into one expected percentage first (our grade calculator can average them), then enter that single percentage here.
