What is Percentage Change Calculator

What is Percentage Change Calculator is a tool that calculates the amount of change from one value to another as a percentage. This makes it clear and easy to know the growth, reduction or difference between the two quantities.

For example:

• In economics, it can be used to evaluate how much a company's revenue has changed between the previous year and the current year.
• In the field of education, a disparity can be found in the average scores of students.
• In statistics, it helps calculate the population growth of a city.

We need two key pieces of information when calculating the rate change:

• Initial Value
• Final Value

The importance of this calculator is its accuracy and time saving nature. It is easy to use in various fields, while reducing the chances of manual errors.

What is the Formula of Percentage Change

Percentage Change is a formal formula that calculates the percentage change from one value to another.

Formula of Rate Conversion:

Percentage Change = ((Final Value - Initial Value) / Initial Value) × 100

Using this you can accurately calculate the change in price, population, quantities.

Calculation Process:

Specify Initial Value and Final Value.

Example:
Initial value: 200
Final value: 250

Calculate the Difference for two values:

Difference = Final Value - Initial Value
Example: 250 - 200 = 50

Divide and multiply the difference by the initial value:

Percentage Change = (50/200) × 100
Calculate: Percentage Change = 25%

Note:

• If the resulting value is greater, it is an increase.
• If less, it is Decrease.

This formula enables users to provide fast and accurate results.
