Find an accurate percent increase or decrease between two numbers. The percent change calculator allows you to enter an initial number and a final number to calculate the absolute difference in terms of percent change. Get step-wise calculations within moments.

Results as positive change show an increase while negative numbers show a decrease in the percentage.

What Is the Percentage Change?

It refers to the real-time change between two numbers as percent. Percentage change is widely used in finance and maths to predict the variation in stock values with respect to time.

The calculator uses a particular equation to tell you whether the change is an increment or decrement.

How to Calculate Percent Change?

The percent change calculations are used for measuring the increase or decrease of quantity or of a given value. 

The percent change formula is given by:

\(Percentage Change = \frac{\text{Final number  – Initial number}}{\text{|Initial number|}} × 100\)

The percentage change calculator provides a simple solution for the percentage change of products and services.

Example 1:

Let’s suppose the annual percentage increase price of a Mobile X increases from intail number $ 1000 to $ 1200. Then what is the percentage change in the price?

Given:

Intail price =  $1000

Final price =  $1200

Percentage change =?

Solution:

The percent change formula is:

\(Percentage Change = \frac{\text{Final Value  – Initial Value}}{\text{|Initial Value|}} × 100\)

Insert the values to calculate the percentage change in the price of mobile.

\(Percentage Change = \frac{\text{1200  – 1000}}{\text{|1000|}} × 100\)

\(Percentage Change = \frac{\text{ 200 }}{\text{1000}} ×  100\)

\(Percentage Change = {\text{ 0.2 × 100 }}\)

\(Percentage Change = {\text{ 20 % }}\)

The percentage change calculator addresses the issue of how much investment is required to get the required output.

Example 2:

Let’s suppose the annual percentage decrease in the cars from $ 5000 to $ 4500. Then what is the percentage change in the price?

Given:

Intail price =  $ 5000

Final price =  $ 4500

Percentage change =?

Solution:

The formula for the percentage change is:

\(Percentage Change = \frac{\text{Final Value – Initial Value}}{\text{|Initial Value|}} × 100\)
\(Percentage Change = \frac{\text{4500 – 5000}}{\text{|5000|}} × 100\)
\(Percentage Change = \frac{\text{ -500 }}{\text{5000}} × 100\)
\(Percentage Change = {\text{ 0.1 × 100 }}\)
\(Percentage Change = {\text{ 10 % }}\)

Here the starting price of the car is $ 5000, and it is decreased due to deflation in the marketplace. The change in the price of the car is 10% overall.

Example 3:

Let’s consider the price of the refrigerators decreased from $ 2000 to $ 1800. Then what is the percentage change in the price of refrigerators during a fiscal year?

Given:

Intail price refrigerators =  $ 2000

Final price refrigerators=  $ 1800

Percentage change in price  =?

Solution:

The formula for the percentage decrease is:

Percentage Change = \frac{\text{Final Value – Initial Value}}{\text{|Initial Value|}} × 100
Percentage Change = \frac{\text{1800 – 2000}}{\text{|2000|}} × 100
Percentage Change = \frac{\text{ -200 }}{\text{2000}} × 100
Percentage Change = {\text{ 0.1 × 100 }}
Percentage Change = {\text{ 10 % }}

The online calculator makes it possible to find the percentage increase or change during the fiscal year

FAQs:

What Does Percentage Change Tell You?

Calculating percent change about the change that occurs when the starting number is increased or decreased with respect to the initial number in terms of percentage. The percent change calculator provides a real-time estimation of the increase in the price of a particular quantity.

How to Calculate Percentage Change When 25 Is Increased to 45?

The percentage change when 25 is increased to 45 is calculated as

Initial Value = 25

Final value = 45

Change in Value = 45 – 25 = 20

Percentage Change = (change / initial) × 100

                                = 20/25 × 100

                                = 80%
