Weighted Average Calculation
The weighted average is calculated as:
Where:
- Score: The score for each assignment (e.g., %, points, letter grade converted to %)
- Weight: The percentage weight of each assignment
- Σ: Sum across all assignments
Usage Notes:
- Scores and weights must be positive numbers.
- Letter grades are converted to percentages (e.g., A = 90%, B = 80%, etc.).
- Results are rounded to 2 decimal places.
- Total weights typically sum to 100% for a complete grade.

Frequently Asked Questions (FAQs)
What is an Assignment Weighting Ratio?
The assignment weighting ratio calculates the weighted average of assignment scores based on their respective weights, reflecting their contribution to the final grade.
Why is weighted average important?
It provides a fair assessment of academic performance by accounting for the varying importance of assignments, such as tests, projects, or homework.
How are letter grades handled?
Letter grades are converted to percentages (e.g., A = 90%, B = 80%, C = 70%, D = 60%, F = 0%) before calculation.
What if weights don’t sum to 100%?
The calculator normalizes the weighted average by dividing by the sum of weights, allowing partial grade calculations.
How does this help students?
It helps students understand how each assignment impacts their final grade, aiding in planning and prioritizing study efforts.
