Calculate exactly what score you need on your final exam to achieve your desired grade
Quick Answer:
Required final grade = (Target − Current × Current weight) ÷ Final weight. Example: want 80%, have 75%, 70% of grade done, final worth 30% → you need (80 − 75×0.70) ÷ 0.30 = 91.67% on the final. Use our calculator for your numbers.
Wondering what grade you need on your final exam to pass or get the grade you want? Our comprehensive guide shows you exactly how to calculate this using simple math and our free final exam calculator.
Use the formula: Required Final Grade = (Target Grade - Current Grade × Current Weight) ÷ Final Weight
Your current average in the class (as a percentage)
Percentage of grade already completed (e.g., 70%)
The final grade you want to achieve
Percentage the final exam is worth
Required Final Grade = (Target Grade - Current Grade × Current Weight) ÷ Final Weight
Required Final Grade = (80 - 75 × 0.70) ÷ 0.30
= (80 - 52.5) ÷ 0.30
= 27.5 ÷ 0.30
= 91.67%
You need 91.67% on your final exam to get an 80% in the class.
If you need a 60% to pass and your current grade is 55% with 70% of the grade completed, you need 70% on your final exam.
If you have an 88% and want to maintain an A (90%), you need 96% on your final exam (assuming 30% final weight).
Use our free final exam calculator to instantly find out what grade you need on your final.
If the required grade is over 100%, it means you cannot achieve your target grade with the final exam alone. You may need to talk to your professor about extra credit opportunities or grade adjustments.
Our calculator is mathematically accurate based on the standard weighted average formula. However, always verify with your professor as grading policies may vary.
Yes! This calculator works for any course with a weighted final exam, including high school, college, and graduate-level courses.
Enter 50 as the final exam weight. The calculator works for any weight from 10% to 100%. Heavier finals have a bigger impact on your grade.
Check your syllabus, gradebook, or learning management system (Canvas, Blackboard, etc.). Use the percentage or average shown before the final.
