Final Grade Calculator — What Do I Need on My Final?

Stop guessing before finals week. Enter three numbers and get the exact minimum score you need on your final exam to lock in your target grade.

What do I need on my final?

Fill in all three fields to see the exact score you need on your final exam.

How it works

  1. 1

    Enter your current grade

    Your overall class percentage right now, before the final (check your syllabus or course portal).

  2. 2

    Set your target grade

    The overall percentage you want to finish the class with — for example 90% for an A-.

  3. 3

    Add the final's weight

    How much of your total grade the final exam is worth. This is listed in your syllabus (commonly 15–30%).

Final exam grade FAQs

How is the required final exam score calculated?

Required score = (Target − Current × (1 − Weight)) ÷ Weight, where Weight is the final's share of your grade as a decimal. Example: currently at 84%, targeting 90%, final worth 20% → (90 − 84 × 0.8) ÷ 0.2 = 114%, so that target isn't reachable without extra credit.

What if the calculator says I need more than 100%?

A required score between 100–110% may still be reachable if your professor offers extra credit on the final. Anything higher is mathematically impossible — consider targeting the next grade tier down.

What if I don't know my current overall percentage?

Add up your scores weighted by each category (homework, quizzes, midterms) per your syllabus, excluding the final. Many course portals like Canvas show this as your “current grade.”

Does this work for finals that replace a midterm grade?

Not directly — replacement policies change the math. Run it once with the standard weight for a baseline, and treat the result as the upper bound of what you'd need.
