Final Grade Calculator
Stop stressing. Instantly calculate exactly what you need to score on your final exam to keep your A or pass the class.
Required Exam Score
Enter your current grade and exam weight to calculate your requirement.
This calculation requires the exam weight to be expressed as a percentage of your total grade. If your class uses a points system instead, divide your desired total points by your current total points.
Taking the Guesswork Out of Finals Week
Finals week is extremely chaotic. Prioritize your studying by knowing exactly where you need to focus.
Smart Study Planning
If you realize you only need a 45% on your Biology final to keep your B, but need a 92% in Chemistry to pass, you instantly know to shift all your studying hours to Chemistry.
Extra Credit Awareness
Avoid false hope. Our visual warnings immediately let you know if a target grade requires over 100%, allowing you to proactively reach out to professors before it is too late.
Stress Relief Outcomes
Often times, you have significantly more wiggle room than you believe. Simply seeing that you "just need to pass" the test relieves test anxiety and improves performance.
The Mathematics of Your Final Grade
The Standard Weighted Formula
Most syllabuses break down grades into weighted percentages (e.g., Homework 20%, Quizzes 30%, Final Exam 50%). To calculate your requirement, you must establish what portion of the class is locked in versus what remains. If the final is worth 20%, that means 80% of your current grade is already locked.
Final = (Desired Grade - (Current Grade × (1 - Final Weight))) / Final WeightUnderstanding Your Wiggle Room
If you currently sit at a 94% and only want to secure a 90%, you have a 4% cushion. However, whether that cushion allows you to fail the final depends entirely on the weight. If the final is weighted heavily, you can miss a lot of questions. If the final is barely weighted, that 4% cushion disappears fast, meaning you must still study rigorously.
Frequently Asked Questions
How does the Final Grade Calculator work?
It uses a weighted average formula. By taking your current grade and multiplying it by its weight (which is 100% minus the final exam weight), the calculator determines how many percentage points you already have secured. It then calculates the remaining points you need from the final exam to reach your desired overall grade.
What if the calculator says I need over 100%?
If the required score is over 100%, it means it is mathematically impossible to reach your target grade through standard testing alone. You will need to ask your professor or teacher for extra credit opportunities to bridge the gap.
What if my class uses a point system instead of percentages?
This calculator is designed for percentage weights. If your class uses total points, you'll need to calculate your current percentage manually first: divide your current points by the total possible points so far. Then, determine the 'weight' of the final by dividing the final exam points by the total points for the entire semester.
Why does the required score seem so low/high?
The required score is heavily influenced by the weight of the final exam. If your final is only worth 10% of your grade, it will barely move the needle—meaning you need an incredibly high score to raise your grade, but even a terrible score will not hurt you much. If your final is worth 40%, it will drastically swing your grade.
