1. What is a Grade Calculator with Weight Percentage?

Definition: This calculator computes a weighted average grade based on individual grades and their respective weight percentages.

Purpose: It helps students and educators determine overall grades when different assignments or exams contribute different percentages to the final grade.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Grade — Individual grade (unitless, typically 0-100 scale)
• Weight % — Percentage contribution to final grade (0-100%)

Explanation: Each grade is multiplied by its weight percentage, summed together, then divided by the total percentage (typically 100).

3. Importance of Weighted Grade Calculation

Details: Weighted grades provide a fair representation of student performance when different assignments have different importance levels in a course.

4. Using the Calculator

Tips: Enter at least one grade and its weight percentage. You can enter up to three grade/weight pairs. Weight percentages should typically sum to 100%.

5. Frequently Asked Questions (FAQ)

Q1: What if my weight percentages don't add up to 100%?
A: The calculator will still work, but your results may not reflect standard grading practices where weights typically sum to 100%.

Q2: Can I use this for letter grades?
A: First convert letter grades to numerical equivalents (e.g., A=4.0, B=3.0) before entering them.

Q3: How many grade/weight pairs can I enter?
A: The calculator supports up to three pairs, but you can leave some fields blank if you have fewer.

Q4: What's the difference between weighted and unweighted grades?
A: Unweighted grades are simple averages, while weighted grades account for different assignment importance.

Q5: Can I use decimals for grades and weights?
A: Yes, the calculator accepts decimal values for both grades and weight percentages.
