What is the mathematical formula to calculate growth % ?
The amount of increase is the new value after growth less the original amount before the growth. The percent growth is the amount of increase times 100% divided by the original amount. As an example, let’s say the number of students in a school grows from 800 one year to 896 the next. First, subtract: 896 – 800 = 96. This is the increase. Next, divide by the original amount: 96(100%) / 800 = 12%. This is the percent increase.
