Calculation Formula
If you want to know how to calculate quarter grades manually, the mathematical formula relies on multiplying your category averages by their respective decimal weights and summing the results.
Quarter Grade (%) = (Test Avg × Test Wt) + (Quiz Avg × Quiz Wt) + (HW Avg × HW Wt) + (Participation × Part Wt) + (Project Avg × Project Wt)
Example Calculation:
- Tests: 85 × 0.40 = 34
- Quizzes: 90 × 0.30 = 27
- Homework: 95 × 0.20 = 19
- Participation: 100 × 0.10 = 10
Total Quarter Grade: 34 + 27 + 19 + 10 = 90% → B+ (or A- depending on scale)

User Tips & Guide
- Verify Category Weights: Always double-check your category weights from your official school grading policy PDF or your teacher’s course syllabus.
- Plan Ahead: Use this 1st quarter grade calculator or 2 quarter final grade calculator before report cards are issued to strategically plan your study time for upcoming finals.
- Adjust for Projects: If you are taking project-heavy courses (like science labs or art portfolios), ensure you adjust the project weight and lower the test weights accordingly.
- Letter Grade Variances: Keep in mind that while this calculator provides standard letter grades, check your specific school’s letter grade scale as percentages may map differently (e.g., an A might be a 93+ instead of a 90+).
