A weighted average grade is not just a simple average — it takes into account how much each assignment is worth in your overall course grade. Most university and school courses use weighted grading, where a final exam may be worth 40% and weekly quizzes only 10%.
The formula for calculating a weighted grade is:
Weighted Grade = Σ (Grade × Weight) ÷ Σ (Weight)
• Quizzes: 85% — Weight: 20%
• Midterm Exam: 72% — Weight: 30%
• Final Project: 90% — Weight: 20%
• Final Exam: 78% — Weight: 30%
Calculation: (85×20 + 72×30 + 90×20 + 78×30) ÷ (20+30+20+30) = 79.7% → C+
This is one of the most searched questions by students before exams: "What score do I need on my final to pass the course?"
The formula is:
Final Needed = (Target − Current × (1 − Final%)) ÷ Final%
• Your current grade: 74%
• Grade you want: 80% (B)
• Final exam is worth: 35%
Final Needed = (0.80 − 0.74 × 0.65) ÷ 0.35 = 91.1%
You need a 91% on your final to achieve a B in the course.
Pro Tip: If your required final exam score is above 100%, it means your target grade is mathematically impossible based on your current standing. Consider revising your target grade downward.

Many students confuse weighted and unweighted grades. Here is the simple difference:
An unweighted grade treats every assignment equally. If you have 5 assignments, each contributes 20% to your final grade regardless of its importance. A weighted grade gives each assignment a specific percentage contribution — so your final exam might be worth 40% and a short quiz only 5%.
Most universities and colleges use weighted grading, which is why our Grade Calculator offers a dedicated weighted mode. Always check your course syllabus to confirm each assignment's weight.
Quick answers to the most common questions about calculating grades.
Multiply each assignment grade by its weight, add all the results, then divide by the total weight. Formula: Weighted Grade = Σ(grade × weight) ÷ Σ(weight). For example: 80%×40% + 90%×60% = (32 + 54) ÷ 100 = 86%. Our calculator does this instantly.
Use our Final Exam Planner tab. Enter your current grade, your target grade, and how much the final is worth. The formula is: Final Needed = (Target − Current × (1 − FinalWeight)) ÷ FinalWeight. If the result is above 100%, your target may not be achievable.
An unweighted grade treats every assignment equally. A weighted grade gives each assignment a different contribution based on its importance. Most university courses use weighted grading — for example, a final exam worth 40% has far more impact on your grade than a 5% quiz.
Standard US conversions: A+ = 97–100%, A = 93–96%, A− = 90–92%, B+ = 87–89%, B = 83–86%, B− = 80–82%, C+ = 77–79%, C = 73–76%, C− = 70–72%, D+ = 67–69%, D = 63–66%, D− = 60–62%, F = below 60%.
