Final Exam Calculator

1. Enter your current weighted course grade as a percentage.
2. Enter the final course grade you want to finish with.
3. Enter how much the final exam counts toward the course grade.
4. The calculator solves the final exam score required to reach that target.

If your current grade is 85, your target is 90, and the final is worth 20%, the required score is (90 - 85 x 0.8) / 0.2 = 110%.

A required score over 100% means the target is not reachable on the final alone unless your class has extra credit, a curve, or other adjustments. A score below 100% is mathematically reachable if all inputs are correct.

What final exam weight should I enter?

Use the percentage listed in your syllabus or gradebook. If the final is worth 20% of the course, enter 20.

What if my final has multiple parts?

Combine the parts into one final exam percentage if they share one final category. If they have separate course weights, calculate each category first.

Why is the required score over 100?

Your target is too high for the final exam weight and current grade. You may need extra credit, a lower target, or more graded work before the final.

Does this account for curves?

No. Curves and instructor adjustments are not predictable from the basic formula.
