Final Grade Calculator
Use this calculator to find the grade needed on your final exam to get a desired grade in a course.
How Grade Calculators Work
A Grade Calculator determines your overall course grade by combining scores from assignments, quizzes, projects, exams, and other assessments according to their assigned weights. Each grade contributes a percentage of the final course grade based on its importance in the course syllabus.
For example, if homework counts for 20% of the course and exams count for 80%, the exam scores will have a much larger impact on the final grade than homework scores. Grade calculators automatically perform these weighted calculations, helping students track academic performance accurately.
Weighted Grade Formula
Most courses use a weighted grading system where each assignment category contributes a specific percentage to the final grade. The weighted grade formula is:
Final Grade = Σ (Grade × Weight)
Example:
- Homework: 85% × 20% = 17.0
- Project: 92% × 30% = 27.6
- Final Exam: 88% × 50% = 44.0
Final Grade = 17.0 + 27.6 + 44.0 = 88.6%
Final Exam Grade Formula
If you want to know the score required on a final exam to achieve a desired course grade, the following formula can be used:
Required Final Exam Grade = (Desired Grade − Current Grade Contribution) ÷ Final Exam Weight
Example:
- Current Grade: 82%
- Desired Course Grade: 85%
- Final Exam Weight: 30%
The calculator determines the minimum score needed on the final exam to reach the target grade.
