The percentage difference calculator is a powerful tool that allows you to quickly and accurately compare two numbers. In this article, we will examine in detail how this calculator works, providing examples and explanations. Additionally, we will discuss who this tool can be particularly useful for and how it can make users' lives easier.

🧬 Did you know that the idea of using percentages to compare numbers dates back to the famous ancient scholar Pythagoras? He was the one who pioneered this approach. His discovery became the basis for modern percentage difference calculators.

## How to find the percentage difference

1️⃣ Finding the Absolute Difference:
First, find the absolute difference between the numbers.
For example, for the numbers 30 and 50:
50 - 30 = 20.

2️⃣ Finding the Average:
Then find the arithmetic mean of these two numbers:
(30 + 50) / 2 = 40.

3️⃣ Calculating the Percentage Difference:
Next, divide the absolute difference by the average, and then multiply by 100 to get the percentage value. In our case:
(20 / 40) * 100 = 50%.

## Percentage difference formula

Before considering the percentage difference formula, let's clarify what this indicator is. The percentage difference indicates the difference between two numbers in percentages. This allows us to understand how one number differs from another in percentage terms.

The percentage difference formula is calculated as follows:

Percentage Difference = 100 × |a - b| / ((a + b) / 2)
Where a and b are the numbers we are comparing.
