# Percentage Change Calculator

Enter the values in the Percentage Change calculator:

Start Value: End Value:

## How to use the Percentage Change Calculator

Let’s review several examples/scenarios in order to demonstrate how to use the Percentage Change calculator.

### Example 1: End Value is greater than the Start Value

Suppose the you have the values below, and your goal is to calculate the percentage change:

• Start Value = 400
• End Value = 500

You can then type those values in the calculator:

Then, click on the “Calculate Percentage Change” button and you’ll get the percentage change of 25%:

### Example 2: Start Value is greater than the End Value

• Start Value = 1000
• End Value = 800

Now enter the above values in the calculator and you’ll get the percentage change of -20%:

### Example 3: Both the Start Value and the End Value are negative

• Start Value = -700
• End Value = -500

For the above values you’ll get the result of 28.571%:

### Example 4: Start Value is positive, while the End Value is negative

• Start Value = 200
• End Value = -500

Now you’ll get -350%:

### Example 5: Start Value is negative, while the End Value is positive

• Start Value = -200
• End Value = 800

And finally, you’ll get the percentage change of 500%:

## How to Manually Calculate the Percentage Change

You may use the formula below in order to derive the percentage change:

100 * (End Value - Start Value)
Percentage Change = |Start Value|

For example, let’s say that you’d like to calculate the percentage change for the following information:

• Start Value = 400
• End Value = 500

If you plug those values in the formula, you’ll get the percentage change of 25%:

100*(End Value - Start Value)    100*(500 - 400)
Percentage Change = |Start Value| = |400| = 25%
