Finals week is stressful enough without the uncertainty of not knowing what you need to score. Our Final Exam Calculator instantly tells you exactly what grade you need on your final exam to achieve your target course grade. Whether you're trying to maintain your A, push from a B to an A-, or just need to pass, this calculator shows you your required score, tells you if it's achievable, and lets you explore different scenarios. Enter your current grade, your final exam weight, and your goal—we'll handle the math and give you a clear game plan for finals.
Your final course grade is calculated as a weighted average of two components: your current grade (all work before the final) and your final exam score. Each component is multiplied by its weight, then added together. For example, if your final exam is worth 25% of your grade, your current coursework counts for the remaining 75%. The formula works backward from your target grade to determine what final exam score, when combined with your current grade contribution, will equal exactly the grade you want. This weighted average system is standard at virtually all high schools and colleges.
Required Final Exam Score Formula
Required Score = (Target Grade - Current Grade × (1 - Final Weight)) ÷ Final WeightStop guessing what you need. Get a precise percentage so you can study with a clear goal in mind.
Immediately see if your target is realistic, challenging, or mathematically impossible—before you waste time on an unattainable goal.
See how scoring 70%, 80%, 90%, or even 100% on your final would affect your course grade.
When you have multiple finals, knowing exactly what you need helps you allocate study hours effectively.
Sometimes discovering you only need a 65% to keep your B is incredibly relieving—and helps you perform better.
View minimum scores needed for each letter grade so you have backup targets if your primary goal isn't achievable.
Calculate your required scores for all classes at once. Create a study schedule that prioritizes the exams where small score improvements yield the biggest grade bumps.
Use the calculator early to see where you're headed. If you'd need 120% on the final to get an A, it's time to recalibrate your semester goals.
A low midterm score can feel devastating, but the math might surprise you. See exactly what's still achievable and what grade you can realistically recover to.
When you're on the borderline (like between a 3.49 and 3.50 GPA), knowing whether you can push one class from B+ to A- can make or break your honors status.
Many scholarships require maintaining a minimum GPA. Calculate the minimum final exam scores across your classes to ensure you don't lose funding.
If you're applying to grad school and need a certain GPA threshold, use the calculator to strategize which classes to focus your final efforts on.
If the calculator shows you need more than 100%, your target grade isn't mathematically possible with a perfect score. This happens when your current grade is too low relative to your target and the final's weight. Options: 1) Check if extra credit is available, 2) Ask your professor if any previous work can be revised, 3) Adjust your target to something achievable. Sometimes accepting a B instead of chasing an impossible A is the healthiest choice.
