When different components carry different importance, a simple average misleads. Our weighted score calculator computes accurate weighted grades for exams, assignments, projects, and fitness metrics — giving proportional credit to each component exactly as intended.
What is a Weighted Score?
A weighted score assigns different levels of importance (weights) to different components before averaging them. Unlike a simple average (where all items count equally), a weighted average reflects the relative significance of each element. University grading systems, performance reviews, financial indices, and quality scoring all use weighted calculations.
Formula
Weighted Score = Σ(Score × Weight) / Σ(Weights)
Example Calculation
A student scores 80 in midterm (40% weight) and 70 in final exam (60% weight).
- Weighted Score = (80×40 + 70×60) / (40+60) = (3200 + 4200) / 100 = 74
- Note: A simple average would give 75 — but the final exam matters more here.
How to Use This Calculator
- Enter your Score 1 (marks or rating out of 100).
- Enter the Weight for Score 1 (importance in %).
- Enter Score 2 and its weight.
- Click Calculate to see your final weighted score.
Real Life Use Cases
- Academic Grading: CGPA, semester grades, internal vs external exam weighting.
- Employee Reviews: Performance appraisals with different KPI weights.
- Investment Portfolio: Calculate weighted average return across holdings with different amounts invested.
- Quality Control: Product quality scores weighted by customer importance ratings.
FAQs
Do weights need to add up to 100?
Ideally yes. If they don't, the formula still works by dividing by the sum of weights — but percentages are the clearest way to define importance.
When should I use weighted average instead of simple average?
Use weighted average when components have unequal importance — like a final exam counting more than a quiz, or a high-value investment dominating a portfolio.
