## Percentage change formula

The percentage change formula is:

**PC = [(NV – OV)/OV] * 100**

- PC = Percentage change
- NV = New value
- OV = old value

## How to calculate percentage change?

- First, determine the new value or final value
- Secondly, determine the old value or initial value
- subtract the new value from the old value then divide by old value
- finally, multiply by 100 you get the percentage change

**For example – ***you bought a stock at $50, and its current value is $60. then calculate the percentage change.*

Initial value when you bought stock is $50

Now the current value of a stock is $60

Percentage Change = ((60 – 50) / 50) * 100

Percentage Change = (10 / 50) * 100

Percentage Change = 0.2 * 100

Percentage Change = 20%

So, the stock price increased by 20%.
