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 the old value
  • finally, multiply by 100 you get the percentage change

Solved Example

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

The initial value when you buy a stock is $50

Now the current value of a stock is $60

Percentage Change = ((60 – 50) / 50) * 100 = (10 / 50) * 100 = 0.2 * 100 = 20%

Percentage Change = 20%

So, the stock price increased by 20%.
