Final Grade Calculator — Score Needed on the Final Exam
CalculatorA final grade calculator solves needed = (target - current × (1 - w)) ÷ w to find the minimum score required on a final exam with weight w.
What is it
If your course grade is a weighted average of the current grade and the final exam, subtracting the current grade’s contribution from the target and dividing by the final weight gives the score you need. A result above 100 means the target is unreachable, and a result below 0 means the target is already secured. Grading policies vary by school, so check the weight in your syllabus.
How to use
- 1Enter your current grade (%).
- 2Enter the target course grade (%).
- 3Enter the final exam weight (%) and check the required score.

FAQ
What do I need on the final worth 40% if my current grade is 85 and I want a 90?
(90 - 85 × 0.6) ÷ 0.4 = 97.5, so you need at least 97.5 on the final.
What if the needed score is over 100?
It means the target is mathematically unreachable even with a perfect final. Consider a lower target or extra-credit options.
