What is Percentage Difference?
Percentage difference is a mathematical concept used to quantify the change between two values as a percentage. It helps in understanding how much one value diverges from another in relative terms. The formula for calculating percentage difference is:
Percentage Difference = (|Value1 - Value2| / [(Value1 + Value2) / 2]) * 100Where:
- Value1 – the initial value
- Value2 – the final value

Examples of Percentage Difference Calculation
LetÂ’s look at a couple of examples illustrating how to use the percentage difference calculator:
Example 1: Price Changes
If a product originally costs $50 and is now priced at $70, the percentage difference would be:
Percentage Difference = (|50 - 70| / [(50 + 70) / 2]) * 100 = (20 / 60) * 100 = 33.33%Example 2: Test Scores
A student scored 80 on a math test and 92 on a subsequent test. The percentage difference is:
Percentage Difference = (|80 - 92| / [(80 + 92) / 2]) * 100 = (12 / 86) * 100 = 13.95%Frequently Asked Questions (FAQs)
