Final Grade Calculator — What Do I Need on My Final?
Find out what grade you need on your final exam to reach your desired course grade. Also see Grade Calculator and GPA Calculator.
How the Final Grade Calculator Works
The final grade calculator determines the minimum score you need on your final exam to achieve a specific overall course grade. It uses the weighted average formula, taking into account your current grade in the class and the percentage weight of the final exam. Enter your current grade, the weight of the final exam, and your desired overall grade, then click Calculate to see exactly what you need to score.
This tool is especially useful during finals week when students need to prioritize study time across multiple courses. If you already have a comfortable margin in one class, you can focus your energy on courses where a higher final exam score is critical.
Final Grade Formula
Required Final Exam Score = (Desired Grade - Current Grade x (1 - Final Weight / 100)) / (Final Weight / 100)
Overall Grade = Current Grade x (1 - w) + Final Exam Score x w
where w = Final Exam Weight / 100
Step-by-Step Example
Current Grade: 85%
Final Exam Weight: 30%
Desired Grade: 90%
Step 1: w = 30 / 100 = 0.30
Step 2: Required = (90 - 85 x (1 - 0.30)) / 0.30
Step 3: Required = (90 - 85 x 0.70) / 0.30
Step 4: Required = (90 - 59.5) / 0.30
Step 5: Required = 30.5 / 0.30
Result: Required = 101.67%
You would need 101.67% on the final — above 100%, so extra credit may be needed.

Tips for Finals Preparation
Knowing what you need on your final exam helps you allocate study time wisely. If you only need a 60% on one final but a 95% on another, focus your energy accordingly. Start by calculating the required score for each class, then rank them by difficulty. Create a study schedule that gives more time to the courses where you need the highest scores. Review past exams and homework problems, as final exams often follow similar patterns. Study in focused blocks of 25-50 minutes with short breaks (the Pomodoro technique) to maximize retention.
Frequently Asked Questions
What if I need more than 100% on my final?
If the calculator shows you need more than 100%, it means achieving your desired grade through the final exam alone is mathematically impossible without extra credit. Consider whether your professor offers extra credit opportunities, or adjust your target grade to something more realistic.
How do I find my current grade?
Check your school's learning management system (Canvas, Blackboard, Moodle, etc.) for your current grade. It is usually displayed as a percentage. If your professor uses weighted categories, use our Grade Calculator to compute your current weighted average first.
How do I find the weight of my final exam?
The final exam weight is listed in your course syllabus. Common weights are 20%, 25%, 30%, or 40%. If the syllabus says "Final Exam: 30% of total grade," enter 30 in the Final Exam Weight field.
Does this work for classes with curved grading?
This calculator assumes a standard percentage-based grading system. If your class uses a curve, the required score may be lower than what the calculator shows. Ask your professor about the curve before relying solely on these numbers.
What is a weighted grade?
A weighted grade means different assignments or categories count for different percentages of your total grade. For example, homework might be 20% of your grade while the final exam is 30%. The final grade is calculated by multiplying each category score by its weight and summing the results.
Can I use this for midterm exams too?
Yes. Enter your current grade (from assignments completed so far), the weight of the midterm exam, and your desired grade. The formula works the same way regardless of which exam you are calculating for.
What grade do most students need to pass?
Most colleges require a C (70%) or D (60%) to pass a course, though some programs require a C or higher in major courses. Graduate programs typically require a B (80%) or higher. Check your school's academic policies for specific requirements.
