Formula used
- Component percentage: pi = (scorei / maxi) × 100
- Weighted mode: Overall = (Σ wi·pi) / (Σ wi), weights in percent.
- Points mode: Overall = (Σ scorei / Σ maxi) × 100
- Unweighted mode: Mean of pi across included components.
- Dropping N lowest: remove N smallest pi before computing.
- Target (weighted): With remaining weight Wr: required average x = [T(Σw + Wr) − Σ(w·p)]/Wr.
How to use this calculator
- Choose your mode: weighted, points-based, or unweighted.
- Add rows. Enter Score, Max, and, if weighted, Weight %.
- Optional: assign Category labels to enable per-category subtotals.
- Use Drop lowest N to ignore weakest components.
- Set a Target overall %; remaining weight auto-calculates from unused weights.
- Open Grade scale to customize letter thresholds and 4.0 mapping.
- Pick a Course or create one, then define its Grade bands.
- Click Copy link to save/share the state via URL.
- Export items with Download CSV or print a clean PDF report.
Generated with the Overall Grade Average Calculator
What is an overall grade average?
The overall grade average summarizes performance across course components as a single percentage. Depending on the syllabus, you may compute it as a weighted mean of component percentages, a pure points ratio, or an unweighted mean.
- Weighted: use component percentages pi with weights wi (in %). Result = Σ(w·p)/Σw.
- Points: sum raw points earned and possible, then divide to get a course-wide percentage.
- Unweighted: treat each component’s percentage equally regardless of max points or weight.
Weighted vs points: quick worked example
| Component | Score | Max | Weight % | pi |
|---|---|---|---|---|
| Homework | 180 | 200 | 30 | 90% |
| Midterm | 78 | 100 | 20 | 78% |
| Quizzes | 85 | 100 | 20 | 85% |
| Final | 0 | 100 | 30 | 0% |
- Weighted: (30·90 + 20·78 + 20·85 + 30·0) / (30+20+20+30) = 50.6%.
- Points: (180+78+85+0) / (200+100+100+100) × 100 = 57.6%.
- Unweighted: (90 + 78 + 85 + 0)/4 = 63.25%.
Different choices can produce different results—match the mode to the syllabus.
