What Is the Percentage Change?

Percentage change refers to the change between two values expressed as a percentage. It is widely used in finance and mathematics to measure how values increase or decrease over time, such as changes in stock prices.

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:

\[ \text{Percentage Change} = \frac{\text{Final Value} - \text{Initial Value}}{|\text{Initial Value}|} \times 100 \]

If you don’t want to go through the step-by-step calculations, simply use the percentage change calculator to get instant results.

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

To Find:

Percentage change =?

Solution:

The percent change formula is:

$ \text{PercentageChange} = \frac{\text{Final Value} - \text{Initial Value}}{|\text{Initial Value}|} \times 100 $

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

$ \text{PercentageChange} = \frac{1200 - 1000}{|1000|} \times 100 $

$ \text{PercentageChange} = \frac{200}{1000} \times 100 $

$ \text{PercentageChange} = 0.2 \times 100 $

$ \text{Percentage Change} = 20% $

Use our percent change calculator to quickly verify your manual calculations and get instant, accurate results for any percentage increase or decrease.

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

To Find:

Percentage change =?

Solution:

The formula for the percentage change is:

$ \text{Percentage Change} = \frac{\text{Final Value} - \text{Initial Value}}{|\text{Initial Value}|} \times 100 $

$ \text{Percentage Change} = \frac{4500 - 5000}{|5000|} \times 100 $

$ \text{Percentage Change} = \frac{-500}{5000} \times 100 $

$ \text{Percentage Change} = 0.1 \times 100 $

$ \text{Percentage Change} = 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

To Find:

Percentage change in price = ?

Solution:

The formula for the percentage decrease is:

$ \text{Percentage Change} = \frac{\text{Final Value} - \text{Initial Value}}{|\text{Initial Value}|} \times 100 $

$ \text{Percentage Change} = \frac{1800 - 2000}{|2000|} \times 100 $

$ \text{Percentage Change} = \frac{-200}{2000} \times 100 $

$ \text{Percentage Change} = 0.1 \times 100 $

$ \text{Percentage Change} = 10 $

For quick results, use the annual percent change calculator to determine the percentage change during a fiscal year.
