About this calculator

This final grade calculator finds the score you need on a final exam to reach a target course grade.

Formula notes

Required final exam grade = (target grade - (1 - final weight) × current grade) / final weight.

Worked examples

  1. Example: current grade 70%, target 80%, and final worth 30% require about 103.33% on the final.
  2. With a current grade of 85%, a target of 90%, and a 40% final, you need 97.5% on the final.

How to use it

  1. Enter your current course grade.
  2. Set your target grade and the final exam weight.
  3. Read the required final-exam score and see whether it is achievable.

Frequently asked questions

What if the required score is above 100%?

That means the final exam must be perfect or the target is unreachable unless the teacher curves or offers extra credit.

Does the calculator support letter grades?

This version uses numeric percentages; enter your percentage equivalents for letter grades.

Limits and interpretation

  • The formula assumes the final is the only remaining grade component and ignores extra credit or dropping the lowest score.
  • Your school's rounding and weighting policy may produce a slightly different required score.
