Introduction
This Final Grade Calculator helps you figure out what you need on your final exam or what your overall grade will be after the exam. It works in three simple modes. First, you can find out what score you need on your final to reach the grade you want. Second, you can see what your overall grade will be if you already know how you did on the final. Third, you can calculate your weighted average across all your class categories like homework, quizzes, midterms, and the final exam. Just enter your numbers, hit calculate, and get your answer right away. Each mode also shows a chart so you can see how different scores change your grade.
How to Use Our Final Grade Calculator
This calculator helps you figure out your grades. Pick one of three modes, type in your numbers, and get your answer right away.
Mode 1: Final Exam Needed
This mode tells you what score you need on your final exam to reach your goal grade.
Current Grade: Enter the grade you have in the class right now as a percent. You can find this in your gradebook or by asking your teacher. If you need help figuring out your current standing, our Grade Calculator can help you work that out.
Desired Grade: Enter the overall grade you want to end the class with as a percent. For example, type 90 if you want an A-.
Final Exam Weight: Enter how much your final exam counts toward your total grade as a percent. Check your syllabus to find this number.
Click Calculate to see the score you need on your final exam. The chart below shows how different final exam scores would change your overall grade.
Mode 2: Overall Grade from Final
This mode tells you what your final course grade will be after you take your final exam.
Current Grade: Enter the grade you have in the class right now as a percent.
Expected Final Exam Score: Enter the score you think you will get on your final exam as a percent.
Final Exam Weight: Enter how much your final exam counts toward your total grade as a percent.
Click Calculate to see your predicted overall grade and letter grade. The chart shows how your overall grade changes based on different final exam scores.
Mode 3: Weighted Average
This mode calculates your overall grade using all your graded categories like homework, quizzes, and exams. If you want a dedicated tool for this type of math, you can also try our Weighted Average Calculator.
Category: Type the name of each grading category, such as Homework, Quizzes, Midterm, or Final Exam.
Score: Enter the grade you earned in that category as a percent.
Weight: Enter how much that category counts toward your total grade as a percent. All weights should add up to 100. If you need help working with percentages, our Percentage Calculator is a handy resource.
Click Add Category to add more rows. Click the trash icon to remove a row. Click Calculate to see your weighted average grade and letter grade. The chart shows how your grade weight is split across categories.
What Is a Final Grade Calculator?
A final grade calculator helps you figure out what score you need on your final exam to get the grade you want in a class. It uses a simple math formula that takes your current grade, the grade you want to end up with, and how much your final exam counts toward your total grade. With those three numbers, it tells you exactly what you need to score. For a broader look at how your grades stack up across an entire semester, check out our Semester Grade Calculator.
How Final Grades Are Calculated
Most classes split your grade into parts called categories. For example, homework might be worth 20% of your grade, quizzes 15%, a midterm 30%, and the final exam 35%. Each category has a weight that shows how much it matters. Your overall grade is found by multiplying each score by its weight, adding those numbers up, and dividing by the total weight. This is called a weighted average. You can use our Average Calculator to quickly compute simple averages, or our Weighted Average Calculator for more complex setups.
Here is the basic formula to find what you need on your final exam:
Final Exam Score Needed = (Desired Grade − Current Grade × (1 − Final Exam Weight)) ÷ Final Exam Weight
For example, if your current grade is 82%, you want a 90% overall, and your final is worth 20% of your grade, you would need a 114% on the final. That is impossible, so you would know to aim for a lower target.
Why This Tool Is Useful
Knowing what you need on your final exam helps you study smarter. If you only need a 70% to keep your grade, you can spend less time stressing. If you need a 98%, you know to study hard or adjust your goal. This calculator takes the guesswork out of grade planning so you can focus on what matters most. Once you have your final grades locked in, you can use our GPA Calculator to see how they affect your overall GPA, or try the College GPA Calculator and Weighted GPA Calculator for more detailed breakdowns. If you are preparing for standardized tests alongside your finals, tools like the SAT Score Calculator, ACT Score Calculator, or Test Grade Calculator can also come in handy.
