How to Calculate Your Grades
Our grade calculator helps students determine their current course standing and what scores they need to achieve their desired final grade. Whether you’re calculating a weighted average, determining what you need on your final exam, or converting points to a percentage, this tool provides accurate results instantly.
Weighted Grade Calculation
Many courses use a weighted grading system where different assignment categories contribute differently to your final grade. For example:
- Exams: 40% of total grade
- Homework: 30% of total grade
- Projects: 20% of total grade
- Participation: 10% of total grade
To calculate your weighted grade, multiply each grade by its weight percentage, then sum all results. Our calculator automates this process for you.
Final Exam Grade Needed
Wondering what score you need on your final exam to pass the class or achieve a certain grade? Our final grade calculator uses this formula:
Required Final Grade = (Desired Grade – (100 – Final Weight) × Current Grade) / Final Weight
This calculation shows you exactly what you need to score on your final exam to reach your target grade.
Points-Based Grading
For classes that use a points system, simply divide the points you’ve earned by the total points possible, then multiply by 100 to get your percentage grade.
Frequently Asked Questions
How do I calculate my grade with weights?
Multiply each grade by its weight percentage, sum all these values, then divide by the total weight. For example, if you scored 85 on exams (40% weight) and 90 on homework (60% weight), your grade would be (85×0.40 + 90×0.60) = 88%.
What if my weights don’t add up to 100%?
Our calculator automatically adjusts for this by using the proportional weights. If your weights total 80%, each weight is effectively scaled up to reach 100%.
How accurate is the final exam grade calculator?
The calculator provides mathematically precise results based on your inputs. However, actual grading policies may vary by instructor, so always check your syllabus.
