Cómo usar esta calculadora
- Enter the score (%) and weight (%) for each category.
- Set unused rows' weight to 0.
- If the weights don't add up to 100% (for example, mid-semester), the result shows your current grade based on completed categories.
Fórmula
Each category's score is multiplied by its weight, and the sum is divided by the total weight.
Weighted grade = Σ(score × weight) / Σ weight
Example
- Homework 92% (20%), quizzes 85% (30%), exams 78% (40%), project 100% (10%).
- = (18.4 + 25.5 + 31.2 + 10) / 100 = 85.1%.
Preguntas frecuentes
What if my weights add up to more than 100%?
Some syllabi include extra credit. The calculator normalizes by the total weight; check whether your instructor does the same.
How do I calculate a weighted average in general?
The same formula applies to any values with weights, such as survey scores or portfolio returns.
What do I need on the final?
Use the final grade calculator with your current weighted grade and the final's weight.
