1. What is Price Percentage Difference?

The Price Percentage Difference measures the relative difference between two prices as a percentage of their average. It's commonly used to compare prices, costs, or values in various fields including finance, retail, and economics.

2. How Does the Calculator Work?

The calculator uses the percentage difference formula:

Where:

• \( p1 \) — First price value
• \( p2 \) — Second price value
• The vertical bars \( | \) indicate absolute value

Explanation: The formula calculates the absolute difference between two prices, divides it by their average, and converts it to a percentage.

3. Importance of Percentage Difference

Details: Percentage difference is valuable for comparing price changes, evaluating discounts or markups, analyzing cost variations, and making informed financial decisions.

4. Using the Calculator

Tips: Enter both price values in the input fields. The calculator will automatically compute the percentage difference. Both values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: What does a 0% difference mean?
A: A 0% difference means the two prices are exactly the same.

Q3: Can the percentage difference be more than 100%?
A: Yes, if one price is significantly larger than the other, the percentage difference can exceed 100%.

Q4: When is percentage difference most useful?
A: It's particularly useful when comparing two equally important values where neither is clearly a "before" or "after" value.

Q5: How should I interpret a negative result?
A: The calculator uses absolute value, so results are always non-negative. The direction of difference isn't indicated.
