1. What is a Percentage Difference Calculator?

Definition: This calculator measures the relative difference between two values as a percentage of their average.

Purpose: It helps compare two values to understand how much they differ relative to their average size.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A \) — First value
• \( B \) — Second value
• The vertical bars \( | \) indicate absolute value

Explanation: The difference between the two values is divided by their average, then multiplied by 100 to convert to a percentage.

3. Importance of Percentage Difference

Details: Percentage difference is useful when comparing two values where neither is clearly a reference or "correct" value.

4. Using the Calculator

Tips: Enter any two numerical values (positive or negative). The result shows how much they differ relative to their average.

5. Frequently Asked Questions (FAQ)

Q1: How is this different from percentage change?
A: Percentage change compares a new value to an old value, while percentage difference compares any two values without reference.

Q2: Can I compare negative numbers?
A: Yes, the calculator works with both positive and negative values.

Q3: What does a 0% result mean?
A: A 0% difference means the two values are identical.

Q4: What's the maximum possible percentage difference?
A: When comparing a value with zero, the percentage difference approaches 200%.

Q5: When should I use this calculator?
A: Use it when comparing experimental results, prices, performance metrics, or any two values where relative difference matters.
