How to use this calculator

Use this calculator to estimate what score is needed on a final exam to reach a target course grade. Enter your current grade, the grade you want, and how much the final exam is worth.

Example

If your current grade is 82%, your target grade is 90%, and the final exam is worth 20% of the course, the calculator estimates what final exam score you need to reach that goal.

Common mistakes to avoid

  • Enter the final exam weight as a percent, not as a decimal.
  • Make sure your current grade is accurate before calculating.
  • Remember that some schools round grades differently.

This tool gives an estimate based on the numbers entered. Always follow the grading rules used by your teacher, class, or school.

Who this tool helps

This calculator helps students plan for a final exam, parents understand a target-grade scenario, and teachers explain how a final exam can affect a course grade.

When to use this tool

Use it when you know your current course grade, the grade you want to finish with, and the percentage of the course that the final exam is worth.

Frequently asked questions

Why does the required score sometimes go above 100%?
That means the target grade may not be reachable from the numbers entered unless the class allows extra credit or uses different rules.

Should a 20% final be entered as 20 or 0.20?
Enter 20. The final-exam weight field uses a percentage.

Does this include future assignments before the final?
Only if those assignments are already reflected in the current grade you enter.
