Grade Calculation Formula:
| From: | To: |
The Weighted Grade Calculator computes your overall grade percentage based on individual assignment grades and their respective weights. This is particularly useful for courses where different assignments contribute different percentages to your final grade.
The calculator uses the weighted average formula:
Where:
Explanation: Each grade is multiplied by its weight, these products are summed, and then divided by the total weight to get the final grade percentage.
Details: Accurate grade calculation helps students understand their current standing in a course, identify areas needing improvement, and predict final grades based on future performance.
Tips: Enter each grade as a percentage (0-100) and its corresponding weight as a percentage (0-100). You can calculate with 1-3 grade/weight pairs. The total weight doesn't need to equal 100% as the calculator normalizes the result.
Q1: What if my weights don't add up to 100%?
A: The calculator automatically normalizes the weights, so they don't need to add up to exactly 100%.
Q2: Can I calculate with more than 3 assignments?
A: This calculator supports up to 3 assignments. For more assignments, you may need to use multiple calculations or a spreadsheet.
Q3: How accurate is the calculated grade?
A: The calculation is mathematically precise based on the inputs provided. Accuracy depends on correctly entering grades and weights.
Q4: Can I use this for different grading systems?
A: This calculator works with percentage-based grading systems. For letter grades or point systems, you'll need to convert to percentages first.
Q5: What if I have extra credit assignments?
A: For extra credit, add it as an additional assignment with the appropriate grade and weight value.
