## What is a percentage difference?

The percent difference is equal to the absolute change in value divided by the mean of the two numbers multiplied by 100. The absolute change between two percentages is expressed in percentage points. The two numbers are so far apart that such a large increase is actually very small.

The percentage difference can be found by first finding their difference, then finding the average, and then dividing and multiplying by 100.

To check the percentage difference between two values, such as two values of 60 and 95, simply use the percentage difference calculator and calculate the answer. This percentage difference calculator uses the absolute value of the difference between both values and divides the result by the average of the two values to calculate the percentage difference between the two values. The second step in calculating the percentage difference is to find their average.

## What is the formula for percentage difference?

- Formula of Percentage difference = |A – B| / ((A + B)/2) * 100
- Percentage difference = (Absolute change / Average value) * 100
- Absolute Change = |Value A – Value B|
- Average value = (Value A + Value B) / 2

## How to calculate the percentage difference?

**Example:-What is the percentage difference between 40 and 60?**

- Value A = 40; let v1
- Value B = 60; let v2
- Absolute difference = |v1 – v2| = |40 – 60| = 20
- Average value = (v1 + v2) / 2 = (40 + 60) / 2 = 50
- % difference = (Absolute difference / Average value) * 100
- % difference = (20 / 50) * 100
- Percentage difference 40%

**Example:-What is the percentage difference between 2 and 3?**

- Value A = 2; let v1
- Value B = 3; let v2
- Absolute difference = |v1 – v2| = |2 – 3| = 1
- Average value = (v1 + v2) / 2 = (2 + 3) / 2 = 2.5
- % difference = (Absolute difference / Average value) * 100
- % difference = (1 / 2.5) * 100
- Percentage difference 40%
