Grade Calculator – Calculate Final & Weighted Grades Easily
The Grade Calculator helps you estimate your final course grade by calculating the weighted average of your assignments, quizzes, exams, and participation. Whether you’re in high school or college, this tool lets you track your academic performance in real time.
How to Use the Grade Calculator
For each component (e.g., exam, homework, project), enter:
- Your earned score (e.g., 87%)
- The weight of that component (e.g., 20%)
The calculator will compute the final grade based on all the weighted components.
Grade Calculation Formula
Final Grade = Σ (Score × Weight)
Ensure the sum of weights equals 100% for an accurate result.
Example
Homework (20%): 90% → 0.20 × 90 = 18.0
Midterm (30%): 80% → 0.30 × 80 = 24.0
Final Exam (50%): 70% → 0.50 × 70 = 35.0
Total = 18 + 24 + 35 = 77%
→ Final Grade = 77%
Common Use Cases
- Planning what score you need on a final exam
- Estimating current grade in a course
- Tracking progress in multiple subjects
- Determining eligibility for scholarships or honors
Why Use a Grade Calculator?
Manually calculating grades can be tedious and error-prone. This tool helps you visualize your progress and make strategic decisions — like whether you need to study more for the final or if you’ve already secured your target grade.
Frequently Asked Questions (FAQs)
What is a passing grade?
Generally, 60% is the minimum passing score, but this may vary by institution.
How do I calculate what I need on the final?
Use the calculator by entering known weights and scores. Leave the final score blank and solve backward.
What if my weights don't add up to 100%?
The results will be inaccurate. Make sure your total weight equals 100% for best accuracy.
Can I use this for all school levels?
Yes, this works for middle school, high school, college, or university level grading.
How do weighted grades differ from simple averages?
Weighted grades consider the importance (weight) of each assignment. A simple average treats all scores equally.
