Final Exam Grade Needed

Enter your current course percentage, how much the final exam counts toward the total, and the overall grade you want. The calculator shows the minimum final exam score required—and flags targets that are already secured or not possible with a score above 100%.

Your mark on all work counted so far, on a 0–100 scale.

Share of the total course grade from the final (e.g. 30 for 30%).

The course percentage you want after the final is included.

How it works

Enter your current course percentage, how much the final exam counts toward the total, and the overall grade you want. The calculator shows the minimum final exam score required—and flags targets that are already secured or not possible with a score above 100%.


The Formula
Points from work so far = current grade × (100 − final weight) / 100
Required on final = (target grade − points from work so far) / (final weight / 100)

Worked Example
  1. Example: 78% now, final worth 40%, want 80% overall

    Work completed so far carries 60% of the grade: 78 × 0.60 = 46.8 points. You need 80 − 46.8 = 33.2 more points from the final. Because the final is 40% of the course, 33.2 ÷ 0.40 = 83%. You need at least 83% on the final to finish at 80% overall.


Tips, Assumptions & Limitations
  • Confirm whether your syllabus lists the final as a percentage of the total course grade.
  • Convert letter grades to percentages first if your mark book uses letters.
  • If the result exceeds 100%, the target may be out of reach—try a lower goal or review missing work.
  • Results are estimates; grading policies differ between schools and modules.
FAQ

Multiply your current percentage by the share of the grade already completed, subtract that from your target, then divide by the final's weight as a decimal. This calculator runs those steps automatically.

That means even a perfect final would not reach your target. You may need to adjust your goal or speak with your instructor about extra credit or resit options at your school.

Yes, as long as marks are on a percentage scale and you know how much the final counts. Letter-grade-only schemes need converting to percentages first.

No. Schools apply rounding, dropped scores, and different weighting rules. Use this as a planning estimate and check your syllabus.
