Grade Calculator
Calculate your weighted grade average and find out what score you need on the final exam to achieve your target grade. Free grade calculator for students.
What is Grade Calculator?
The Grade Calculator computes your weighted average grade across assignments, quizzes, and exams based on their assigned weights. It also calculates the minimum score needed on remaining assessments to achieve your target grade.
How to Calculate Weighted Grade
- Enter each assessment name, your score, and its weight (%)
- Enter your target overall grade
- Click Calculate to see your current weighted average and required scores on remaining assessments
How Grade Calculator is Calculated
Weighted Average = Σ(Score × Weight) / Σ(Weights). Required score on final = (Target × Total Weight − Current Weighted Sum) / Remaining Weight.
Worked Example
Assignments (30% weight): scored 85%. Midterm (30%): scored 78%. Final exam (40%): need at least 88% to get 84% overall. Calculation: (84 × 100 − 85 × 30 − 78 × 30) / 40 = 87.75%.
Common Use Cases
- Current course grade check
- Final exam target calculation
- GPA impact analysis
- Semester planning and grade tracking
Common Mistakes to Avoid
- Treating all assessments as equal weight — a quiz worth 5% matters far less than a final exam worth 40%. Use weighted averages.
- Not accounting for dropped/excluded grades — if your professor drops the lowest quiz, exclude it from the calculation.
- Calculating percentage of percentage incorrectly — scoring 90% on a 10% quiz adds only 9 points to your weighted total, not 90.
- Forgetting extra credit or curve adjustments — these can change your effective score but are hard to predict in advance.
Frequently Asked Questions
How do weighted grades work?
Each assessment contributes proportionally to your overall grade based on its weight. A 90% on a 40% final impacts your grade more than a 90% on a 5% quiz.
Is it possible to still get an A?
Enter your current scores and target grade. The calculator will tell you the exact score needed on remaining assessments, or if the target is mathematically impossible.
