How to calculate percent change

 To calculate the percent change between two values, you can use the following formula:

Percent Change = [(New Value - Old Value) / |Old Value|] x 100

Here's a step-by-step guide on how to calculate percent change:

1. Subtract the Old Value from the New Value.
2. Take the absolute value of the result from step 1 (ignore the negative sign, if any).
3. Divide the absolute value by the Old Value.
4. Multiply the result from step 3 by 100 to get the percent change.

Let's illustrate this with an example:

Suppose you want to calculate the percent change in the price of a stock from $50 (Old Value) to $60 (New Value):

Percent Change = [($60 - $50) / |$50|] x 100 Percent Change = [($10) / $50] x 100 Percent Change = (0.2) x 100 Percent Change = 20%

So, the percent change in the stock price is 20%. This means the price increased by 20%.
