Find exactly what score you need on your final exam to reach a target overall grade in the course.
Final Exam Grade Calculator
LiveThe formula
Currently at 82%, final exam worth 30% of the grade, targeting an overall 85%: needed score = (85 - 82x0.70) / 0.30 = 92% on the final.
Step-by-step guide
- Enter your current grade - your overall percentage in the course before the final exam.
- Enter the final exam's weight - what percentage of your total grade it counts for, from the syllabus.
- Enter your target overall grade and see exactly what score you need.
When the answer says "not achievable"
If the required score comes out above 100%, it means your target grade is mathematically out of reach no matter how well you do on the final - even a perfect score won't get you there, given your current grade and the exam's weight. This is genuinely useful information early: knowing a target is out of reach lets you reset expectations or focus energy elsewhere, rather than studying toward an impossible number. Conversely, a result at or below 0% means you've already secured your target grade regardless of the final's outcome.
Common mistakes
Frequently asked questions
Where do I find my final exam's weight?
Your course syllabus should list it directly - commonly somewhere between 15-40% depending on the course and institution. If it's not listed, ask your instructor directly, since assuming a wrong weight will skew the result.
Does this work if I have both a final exam and other remaining assignments?
This version assumes the final exam is the only thing left. If other work remains too, estimate scores for those separately first, then treat the final exam's weight as just its own portion of the total remaining grade.
Can I use this for any exam, not just a final?
Yes - the same math applies to any single remaining assessment with a known weight, whether it's a midterm, final, or major project.
