1. What is a Grade Calculator by Weight Percent?

Definition: This calculator computes the weighted grade based on the sum of weighted scores and total weight.

Purpose: It helps students and educators determine final grades when different assignments or exams carry different weights.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Grade — Final weighted grade (unitless)
• Weighted Sum — Sum of all (score × weight) values
• Total Weight — Sum of all weight values

Explanation: The weighted sum represents the total earned points adjusted for weights, divided by the total possible weighted points.

3. Importance of Weighted Grade Calculation

Details: Proper grade calculation ensures fair assessment when different components of a course contribute differently to the final grade.

4. Using the Calculator

Tips: Enter the weighted sum (sum of all score×weight products) and total weight (sum of all weights). Total weight must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a weighted sum?
A: The sum of each score multiplied by its respective weight. For example: (Quiz1×10%) + (Midterm×30%) + (Final×60%).

Q2: What if my total weight doesn't equal 100%?
A: The calculator works with any total weight value. It will normalize the result automatically.

Q3: Can I use this for non-percentage weights?
A: Yes, the calculator works with any weight units as long as you're consistent (e.g., points instead of percentages).

Q4: How do I calculate the weighted sum?
A: Multiply each component's score by its weight, then sum all these products.

Q5: What does the result represent?
A: The result is your overall grade on the same scale as your input scores (e.g., if inputs were out of 100, result is out of 100).
