How to Use the Final Grade Needed Calculator

  1. Enter your current grade in the course.
  2. Enter the grade you want to end up with.
  3. Enter how much the final exam is worth (%).
  4. Click Calculate to see the score you need.

Formula

Needed Score = [Desired − Current × (1 − Weight)] ÷ Weight

Worked Example

With an 82% current grade, a 90% goal, and a final worth 20%, you'd need a 122% — meaning the goal isn't reachable, so aim to raise your current grade instead.

About This Calculator

This calculator uses your current weighted grade and the final exam's weight to back-solve for the score needed to hit your target — useful for setting realistic study goals.

Frequently Asked Questions

How is the final grade needed calculated?

It works backward from your target overall grade, current grade, and the weight of the remaining assignment/exam to find the minimum score you need on it.

What information do I need to use this calculator?

Your current grade, the weight percentage of the remaining assignment or final exam, and your target overall course grade.

What if the required score is above 100%?

That means it's mathematically impossible to reach your target grade with the remaining weight available — you'd need extra credit or a grade recalculation to hit that goal.
