Grade Calculator

A grade calculator is an online tool that helps students calculate their final course grade based on individual assignment scores and weights. Whether you're tracking current progress, planning study priorities, determining what score you need on the final exam, or understanding your overall performance, our grade calculator handles weighted grading systems used in most educational institutions.

This calculator determines your final grade by multiplying each assignment category's average score by its weight percentage, summing the weighted scores, and converting the total to a letter grade. It supports multiple assignment categories (tests, quizzes, homework, projects, participation), custom weighting systems, and what-if scenarios to show what grades you need on remaining assignments to achieve target final grades.

Understanding your current grade and projecting your final grade is essential for academic planning and stress reduction. Students benefit from knowing exactly where they stand in a course, which assignments have the most impact on their grade, and what scores they need on future assignments to achieve their goals. This knowledge helps prioritize study time, manage workload, and reduce anxiety about grades.

Educators use grade calculators to verify grading calculations, help students understand grading policies, and demonstrate how weighted categories affect final grades. Students facing challenging final exams use it to calculate minimum required scores to pass or achieve desired grades. Parents and tutors benefit from understanding students' grade situations to provide appropriate support.

The tool ensures accuracy by precisely calculating weighted averages, provides instant results as you input scores, and allows scenario testing to set realistic goals. It's particularly valuable when planning study time before finals, understanding the impact of late assignments, evaluating whether to invest extra effort in high-weight assignments, or communicating with teachers about grade standings.

Final Exam Planning: Calculate what score you need on the final exam to achieve your desired course grade, helping focus study efforts.

Current Standing: Track your current grade throughout the semester by entering completed assignments and their weights.

Grade Goals: Determine what scores you need on remaining assignments (projects, papers, exams) to reach target final grades.

Assignment Priorities: Understand which assignment categories have the most impact on your final grade to prioritize study time effectively.

What-If Scenarios: Test different grade scenarios to understand how performance on upcoming assignments affects your final grade.

Using our grade calculator is straightforward: enter each assignment category (tests, homework, quizzes, etc.), the category's weight as a percentage of the final grade, and your current average or score in that category. The calculator instantly shows your current grade percentage and letter grade. For future assignments, enter expected or required scores to see projected final grades.

The calculator uses the weighted average formula: Final Grade = Σ(Category Score × Category Weight). Weights must total 100%. For example, if tests are 50% (with 85% average), quizzes are 30% (with 90% average), and homework is 20% (with 95% average), the calculation is: (85 × 0.50) + (90 × 0.30) + (95 × 0.20) = 42.5 + 27 + 19 = 88.5%. Most schools use: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%). All calculations are performed locally in your browser for privacy.
