Final Grade Calculator: What Do I Need on My Final?
Enter your current grade and final exam weight to instantly see the score you need. Compare scenarios for different target grades and plan your study time strategically.
Quick Answer:
To find out what you need on your final, use the formula: Required Score = (Target Grade - Current Grade × (1 - Final Weight)) / Final Weight. For example, if you have an 85% and your final is worth 30%, you need a 101.7% to get a 90% — meaning a 90% is not possible. CourseLink's free calculator does this instantly for all your courses.
How to Calculate What You Need on Your Final Exam
Finals week is one of the most stressful periods of the college semester. One of the biggest sources of anxiety is not knowing where you stand in a class or what score you need on the final to hit your target grade. CourseLink's final grade calculator removes the guesswork so you can study strategically.
The Final Grade Formula
The formula behind every final grade calculation is: Required Score = (Target Grade - Current Grade × (1 - Final Weight)) / Final Weight. This works because your final grade is the weighted average of your current grade and your final exam score. If your current grade is 82%, the final is worth 25%, and you want an 88%, the math is: (88 - 82 × 0.75) / 0.25 = 106%. That means an 88% is not achievable, and you should aim for a more realistic target like 85%.
Understanding Weighted Grading
Most college courses use weighted grading, where different assignment categories count for different percentages of your final grade. A common breakdown might be: Homework 20%, Quizzes 15%, Midterm 25%, Final Exam 30%, Participation 10%. Your current grade is the weighted average of all completed categories. To calculate it manually, multiply each category average by its weight and sum the results. Our calculator handles any number of categories with any weights.
Strategic Study Planning Based on Your Final Grade Needs
Knowing what you need on each final lets you allocate study time where it matters most. Not every exam deserves equal preparation time. Smart students triage their finals based on impact and achievability.
Prioritizing Your Finals
After running the numbers for all your courses, sort your finals by two criteria: the weight of the final exam and how close you are to a grade threshold. A course where you have an 89.2% and need a 90% for an A deserves more focused study time than a course where you have a comfortable 94%. Use CourseLink's multi-course final planner to see all of your finals ranked by impact on your GPA.
When to Focus on Other Courses Instead
Sometimes the math shows that no realistic final exam score will change your letter grade in a particular course. If you have a 92% and the final is only worth 15%, even a 70% on the final only drops you to an 88.7% — still a B+. In that case, redirect your study hours toward courses where the final can actually move the needle. This strategic approach can raise your overall semester GPA by focusing effort where it counts.
Common Mistakes When Estimating Final Grades
Many students miscalculate their standing because they forget to account for assignment weights, assume all categories are equally important, or overlook dropped grades. Another common error is using the simple average of all scores rather than the weighted average. For example, if you have a 95% homework average (worth 15%) and a 75% midterm (worth 30%), your weighted average is not 85% — it is 81.7%. Always use weighted calculations, and let CourseLink's calculator handle the math so you can focus on studying rather than spreadsheets.

Frequently Asked Questions
How do I calculate what I need on my final exam?
Use the formula: Required Final Score = (Target Grade - Current Grade × (1 - Final Weight)) / Final Weight. For example, if you have an 85% and your final is worth 30% of your grade, and you want a 90%, you need: (90 - 85 × 0.70) / 0.30 = 101.7%. CourseLink's calculator does this math instantly for any combination of grades and weights.
What if I need more than 100% on my final?
If the calculator shows you need more than 100%, it means reaching that target grade is not mathematically possible with the final exam alone. Consider aiming for a more realistic target grade. The calculator will show you the highest grade you can still achieve given your current standing.
Is the final grade calculator free?
Yes, CourseLink's final grade calculator is completely free. Calculate what you need on any number of finals without creating an account. Sign up for free to save your courses and track grades across the semester.
How do I find the weight of my final exam?
Check your course syllabus. The grading breakdown section will list the percentage each component is worth (e.g., Final Exam: 25%, Midterm: 20%, Homework: 30%, Participation: 10%, Quizzes: 15%). If your syllabus is unclear, ask your professor or TA.
Can I calculate my current grade without the final?
Yes. Enter all of your completed assignments, quizzes, and exams with their respective weights. The calculator will show your current weighted average before the final. This is your starting point for figuring out what you need on the final.
What if my professor uses points instead of percentages?
Convert to percentages by dividing earned points by total possible points. For example, if your midterm was 78 out of 100, that is 78%. If your homework total is 180 out of 200, that is 90%. Our calculator also supports direct point entry if you prefer.
Does extra credit affect the calculation?
If extra credit is already reflected in your current grade, the calculator accounts for it automatically. If you have upcoming extra credit opportunities, add those points to your projected score. Our tool lets you factor in bonus points when calculating your required final exam score.
Can I use this for midterm exams too?
Absolutely. The calculator works for any weighted exam or assignment. Enter your current grade, the weight of the upcoming midterm, and your target grade to see what you need. It works the same way regardless of whether the exam is a midterm, final, or any other weighted assessment.
