How to Use Weighted Grade Calculator
The Weighted Grade Calculator lets you see your current standing and plan what score you need on upcoming assessments.
- Enter each grade item — Type a name (e.g. Homework, Midterm, Final Exam), your score out of 100, and the percentage weight for that item.
- Add more items — Click Add Item to include quizzes, projects, or any other graded components. The Weighted Grade Calculator supports an unlimited number of entries.
- Set a target grade (optional) — Enter your desired final grade, and the Weighted Grade Calculator tells you what score you need on the remaining unweighted portion.
The Weighted Grade Calculator updates instantly as you type, so you can experiment with different scenarios without any extra steps.
Formula & Theory — Weighted Grade Calculator
The Weighted Grade Calculator uses the standard weighted average formula:
Weighted Grade = Σ(Score × Weight) ÷ Σ(Weight)
If the sum of all weights equals 100%, the formula simplifies to:
Weighted Grade = Σ(Score × Weight%)
| Symbol | Meaning |
|---|---|
| Score | Points earned on each assessment |
| Weight | Percentage importance of each item |
| Σ | Sum over all valid entries |
Target Grade Calculation
When weights don't total 100%, the Weighted Grade Calculator can determine the score needed on the remaining weight:
Needed Score = (Target × 100 − Σ(Score × Weight)) ÷ Remaining Weight
If the needed score exceeds 100, the Weighted Grade Calculator flags the target as unachievable.
