It allows you to fill the x and y inputs and click on the calculate button. In a short span of time, you will find the percent change result with a detailed explanation. .

**What Is The Percent Change From X To Y? Online Calculator:** Are you looking for the perfect tool that helps you in calculating the percent change of x and y? You've stepped into the right page as we have developed a simple tool ie., What Is The Percent Change From X To Y? free online calculator. It makes your calculations much easier and faster.

A percent change also known for percent increase/decrease. It is defined as percent increase and percent decrease in the sense that we can notice both directions of change.

The formula that is used to calculate the percent change is as follows:

**(new_value - original_value) / |original_value| * 100**

Here, we are calculating the percent change from x to y so the formula is written as

**((Y-X)*100)/Y**

The following steps on calculating the percent change are pretty simple to understand the concept. Thus, proceed with the steps and get accurate results manually:

- Initially, we have to identify both x and y values from the given question.
- Now, calculate the difference between the x and y values.
- Take the resultant and divide it by x value.
- In this step, you have to simplify the above expression and multiply the result by 100.
- Finally, you will get the desired percent change from x to y output.

**Example 1:**

What is the percentage change from 40 to 50?

**Solution: **

Given X = 40

Y = 50

The percent change formula is **((Y-X)*100)/Y**

Substitute the values in the formula

Percent change = ((50-40)*100)/50

= 10*100/50

= 1000/50

= 25%

Hence, the percent change from 40 to 50 is 25%.

**Example 2: **

What is the percent change from 76 to 34?

**Solution: **

Given X = 76

Y = 34

Apply the formula of percent change ie., **((Y-X)*100)/Y**

Put the x and y values and simplify the expression;

Percent change = ((Y-X)*100)/Y

= ((34-76)*100)/34

= -42*100/34

= -4200/34

= -55.26

Thus, 34 is a **55.26% **decrease of 76.

**1. What is the percentage change between two numbers?**

The result calculated by using this ((Y-X)*100)/Y is called the percentage change between two numbers.

**2. What is the percent change from 120 to 108?**

-10% is the percentage change from 120 to 108.

**3. What is the formula of percentage change between initial value and final value?**

The formula of percentage change between initial value and final value is **(final_value - initial_value) / |initial_value| * 100. **
