Percentage change Calculator

The Mathematics Master brings you a free Percentage Change Calculator that shows the percentage change, whether it is increased or decreased. Our online tool for calculating percentage changes speeds up the calculation and shows the result in a split second.

\(\%Change = 100 × \frac{final - initial}{|initial|} \)

While a negative change is expressed as a decrease in the absolute value of the percentage value, a positive change is expressed as an increase in the percentage value.

You may compute the percentage difference between two numbers—the initial value and the updated value—using a percentage change calculator.

What Does Percentage Change Mean?

Percentage Change describes the intensity of change over time. Either a percentage increase or a percentage decrease can be used to compute the percentage change.

How do I Calculate the Percent Change?

Take the difference between the starting value and the final value to determine the percent change.

Subtract the beginning value from its absolute value.

Add 100 to the result.

Alternatively, you can use our free percent change calculator online.

How to use Percent Change Calculator

Simply enter the new and starting values in the corresponding boxes.

Click “calculate” to start.

In a flash, you’ll receive your % change.

Percentage Change Formula

Percentage Increase or Decrease \( = \dfrac{NV – IV}{IV} × 100 \)

NV = New Value

IV = Initial Value

Different ways to Calculate the Percentage change

Use your preferred method from the following two examples of percentage change calculations:

Method 1

Calculate the change in step one (subtract the old value from the new value)

Subtract the new value from the change (you will get a decimal number)

Convert that to a percentage by multiplying by 100 and adding the symbol “%”

Method 2

Subtract the Old Value from the New Value (you will get a decimal number)

Multiply that by 100 and add the symbol “%” to convert it to a percentage.

Take 100% out of that.

Note that if the result is negative, just take away the minus sign and call it a drop. Positive results are shown as the percentage increases.


Example 1: In 2021, Oxford accept 2,000 requests for admission, and in 2022, they accept 3,000 requests for admission. Calculate the percentage change of admission past two years.

\(=100× \dfrac{3000-2000}{200} \)

\(=100× \dfrac{1000}{200} \)

\(=100× 0.5\)

\(=50\% \), it means admission increases by 50%. You can also calculate this by using a Percentage Increase Calculator.


What is the average rate of change?

The average rate of change measures how quickly one function is changing in comparison to another. Calculating the rate at which the output (y-values) changes in relation to its input is all that is required of it (x-values).

What is an amplitude calculator?

The term “amplitude” refers to the greatest distance that a point on a vibrating body can travel. The vertical distance between the wave’s peak and its equilibrium point is its amplitude. The amplitude calculator needs to know the wave’s frequency and its path’s length to calculate its amplitude.
