Percentage Change Calculator

Step 1: Select the Calculation Type
On the tool's interface, you'll see two radio buttons:
- **% Change**: Calculates the percentage change between two values.
- **% Of**: Calculates the percentage of the final value with respect to the initial value.
Choose the desired calculation type by selecting the corresponding radio button.
Step 2: Enter the Initial Value
In the **"Initial Value"** field, enter the starting value for your calculation. Example: Enter the price of a stock at the start of the period.
Step 3: Enter the Final Value
In the **"Final Value"** field, enter the value after the change has occurred. Example: Enter the price of the stock at the end of the period.
Step 4: Click on "Calculate"
Once both values are entered, click on the **"Calculate"** button to compute the result. The percentage change or percentage of the final value will be displayed.
Step 5: View the Results
After clicking **"Calculate"**, the result will be shown. You will see: - **Percentage Change**: How much the value has increased or decreased in percentage terms. - **Difference**: The actual difference between the initial and final values.
Step 6: Reset the Fields (Optional)
If you want to clear the entered values and start a new calculation, click the **"Reset"** button.

Note: This tool is helpful for calculating percentage changes in values like stock prices, sales figures, and more.

Step 1: Understand the Formula
The formula for calculating the percentage change between two values is:
```
% Change = ((Final Value - Initial Value) / Initial Value) * 100
```
This formula helps you determine how much a value has increased or decreased in percentage terms.
Step 2: Identify the Values
- **Initial Value (X1)**: The starting value (e.g., price of a stock at the beginning of the period).
- **Final Value (X2)**: The value at the end of the period (e.g., price of the stock at the end of the period).
Step 3: Subtract Initial Value from Final Value
To calculate the change in value, subtract the initial value (X1) from the final value (X2):
```
Change = Final Value - Initial Value
```
Step 4: Divide the Change by the Initial Value
Next, divide the change by the initial value (X1) to get the relative change:
```
Relative Change = Change / Initial Value
```
Step 5: Multiply by 100
Finally, multiply the relative change by 100 to convert it into a percentage:
```
% Change = (Relative Change) * 100
```
This gives you the percentage change between the initial and final values.
Step 6: Example Calculation
Suppose the initial value of a stock is $100 and the final value is $120. The calculation would be:
```
% Change = ((120 - 100) / 100) * 100 = (20 / 100) * 100 = 20%
```
Therefore, the percentage change is +20%, indicating a 20% increase.
