Enter your current grade, your target final grade, and what percentage your final exam counts for. The calculator instantly shows the minimum score you need on the final.
- Enter your current grade. This is your grade right now before the final, as a percentage (e.g., 82 for 82%).
- Enter your target grade. The overall course grade you want to finish with (e.g., 85 for a B).
- Enter the final exam weight. How much the final counts toward your overall grade as a percentage. A common value is 20-40%. Check your syllabus.
- Read the result. If the needed score is above 100%, your target is not mathematically achievable. If it is 0% or lower, you have already secured your target grade regardless of the final.
About the Final Grade Calculator
The formula used is: needed score = (target grade - current grade x (1 - final weight)) / final weight. For example, if your current grade is 82%, the final is worth 30%, and you want 85% overall: needed = (85 - 82 x 0.70) / 0.30 = (85 - 57.4) / 0.30 = 27.6 / 0.30 = 92%. You would need a 92% on the final.
The formula works because your final grade is a weighted average. The portion of your grade already locked in equals your current grade multiplied by the non-final weight. The remaining points come from the final. Solving for the final score needed to reach your target gives the formula above.
Frequently Asked Questions
What if the needed score is over 100%?
If the calculator shows a needed score above 100%, your target grade is not mathematically achievable given your current grade and the weight of the final. In this case, consider adjusting your target grade downward to find an achievable goal, or focus on doing as well as possible on the final to maximize your outcome.
How do I find out what my final exam is worth?
Check your course syllabus. Professors typically list the grading breakdown showing how much each component (homework, quizzes, midterm, final) counts toward the overall grade. The final exam weight is usually listed as a percentage, such as "Final Exam: 30%."
What does "current grade contribution" mean?
The current grade contribution is how many percentage points your current grade adds to your final course grade, after accounting for the weight of the final exam. If your current grade is 82% and the final is worth 30%, your current work contributes 82 x 0.70 = 57.4 percentage points toward your total grade. The remaining 42.6 points are possible through the final exam.
What grade do I need on the final to pass the class?
Set your target grade to 60 (or whatever your school's passing threshold is, often 60-70%) and enter your current grade and final weight. The calculator will show the minimum score you need on the final to pass. If you are already guaranteed to pass regardless of the final score, the result will show 0% or a negative number.
