That score is over 100%, so the target grade is not mathematically possible with these inputs.

Moving from 0% to 100% on a final worth 30% changes the overall course grade by 30% — from 59.50% to 89.50%.

How to Calculate the Score You Need on Your Final Exam

Step-by-step method to find the exact score needed on a final exam to hit your target course grade, using either your current percentage or completed assignment scores.

  1. 1. Enter current grade or assignment scores: Choose "Yes" to type your current grade directly, or "No" to enter each completed assignment's score and points possible. The calculator works out your current grade for you.
  2. 2. Enter target course grade: Type the percentage you want to achieve, or use one of the quick letter-grade buttons provided.
  3. 3. Enter final exam weight: Input the percentage of your course grade that the final exam determines (e.g., 20%, 30%).
  4. 4. Review required score and projections: See the exact score you need, whether your target is mathematically reachable, and explore what-if scenarios for different final exam scores.

How to Use the Final Exam Calculator

  1. Enter current grade or assignment scores. Choose "Yes" and type your current grade directly, or choose "No" and enter each completed assignment's score and points possible — the calculator works out your current grade for you.
  2. Enter target course grade. Type a percentage, or use one of the quick letter-grade buttons.
  3. Enter final exam weight. The percentage of your course grade that the final exam determines.
  4. Calculate required final score. The result updates live, and the Calculate button re-confirms it.

How Is the Required Final Exam Score Calculated?

The calculator solves for the final exam score using:

  • Required Final Score = (Target Grade − Current Grade × (1 − Final Weight)) ÷ Final Weight
  • Current Grade — your grade from coursework completed before the final, as a percentage.
  • Target Grade — the overall course grade you want to reach, as a percentage.
  • Final Weight — the fraction of the course grade the final exam determines (entered as a percentage, converted to a decimal for the formula).

What Does Current Grade Mean?

Current grade should represent only the coursework completed before the final exam — homework, quizzes, tests, projects, participation, and anything else already graded. The final exam itself must not already be included in that percentage, or the calculation will double-count it.

What If the Required Score Is Over 100%?

A required score above 100% means the target is not mathematically reachable with the current grade, target, and final weight supplied — no exam score can push the course grade that high. The calculator still shows the exact mathematical requirement (for example, 101.67%) rather than silently capping it at 100%, alongside the highest course grade actually attainable — the Maximum Possible Course Grade, which assumes a perfect final.

How Is the Maximum Possible Grade Calculated?

The maximum possible course grade assumes a 100% score on the final exam: Maximum Course Grade = Current Grade × (1 − Final Weight) + 100 × Final Weight. The minimum possible course grade uses the same formula with a 0% final exam score instead.

Worked Example

Current grade: 85%. Target course grade: 90%. Final exam weight: 30%.

  • Required final score: (90 − 85 × 0.70) ÷ 0.30 = 101.67%
  • Minimum possible course grade (0% on the final): 59.50%
  • Maximum possible course grade (100% on the final): 89.50%

Frequently Asked Questions

Q: What grade do I need on my final?

Enter your current grade, target course grade, and the final exam's weight, and the calculator solves for the exact score you need.

Q: How is the required final exam score calculated?

Required Final Score = (Target Grade − Current Grade × (1 − Final Weight)) ÷ Final Weight, with Final Weight entered as a percentage and converted to a decimal.

Q: What if I don't know my current grade?

Choose "No" and enter your completed assignment scores — the calculator adds up total points earned over total points possible to find your current grade automatically.

Q: Can I calculate my current grade from assignment scores?

Yes. This calculator uses the total-points method: (sum of points earned ÷ sum of points possible) × 100. It does not weight assignments by category.

Q: What if the required final score is over 100%?

It means the target isn't mathematically reachable with your current inputs. The calculator still shows the exact number rather than capping it, plus the highest course grade you can actually reach.

Q: What is the highest grade I can get in the course?

The Maximum Possible Course Grade, calculated assuming a perfect 100% on the final exam.

Q: What happens if my final exam is worth 100%?

Your current grade has no influence on the final course grade — the required final score simply equals your target grade.

Q: What happens if my final exam is worth 0%?

The final exam cannot change your course grade at all. If your current grade already meets the target, it's secured; otherwise the target can't be reached through the final.

Q: Does my current grade include the final exam?

No — it should reflect only coursework completed before the final. Including the final in your current grade will double-count it.
