1. What is an Overall Grade Percentage Calculator?

Definition: This calculator computes the weighted average percentage based on individual grades and their respective weights.

Purpose: It helps students and educators determine overall course grades when different assignments/exams have different weights.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Grade — Individual grade percentage (0-100%)
• Weight — Relative importance of that grade
• ∑ — Sum of all grade-weight products

Explanation: Each grade is multiplied by its weight, these products are summed, then divided by the total of all weights.

3. Importance of Weighted Average Calculation

Details: Provides accurate course grading when different components (exams, homework, projects) contribute differently to the final grade.

4. Using the Calculator

Tips:

• Add all your grades and their respective weights
• Weights can be percentages, points, or arbitrary values
• The calculator automatically normalizes the weights
• Click "Add Another Grade" for additional entries

5. Frequently Asked Questions (FAQ)

Q1: What if my weights don't add up to 100?
A: The calculator automatically normalizes weights, so they don't need to total any specific number.

Q2: Can I use points instead of percentages?
A: Yes, as long as you maintain consistent units (all percentages or all points).

Q3: How many grade entries can I add?
A: You can add as many as needed - the calculator will handle them all.

Q4: What if I get 100% on everything?
A: Your overall percentage will be 100% regardless of weights.

Q5: How accurate is this calculator?
A: It provides precise mathematical calculations based on your inputs.
