Enter the values in the **Percentage Change calculator**:

## 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%
