How do you solve a percent change equation?

You have to use this formula: %change = ((new amount - original amount) / original amount) x 100

For example, if you originally had an investment of $300 and 5 years later you had $326.25 in your account and you want to see the percent change, you'd use the formula above % change=((326.25-300)/300) x 100 % change=(26.25/300) x 100 % change=.0875 x 100 % change= 8.75

Therefore, the change in percent is 8.75%
