For example, currently, the population of Bangladesh is a lot more than it was in the year 2007. But this information is not enough to measure the severity of this issue. To determine the relative scale or the rate of the increasing population, we will have to use the mathematical formula.

Percent Increase Formula:

Percent Increase Formula:

The formula of percentage increase is as follows:

Percentage increase = [(New number – Original Number) / Original Number] × 100


How to Calculate Percentage Increase

The percentage increase can easily be measured by using the formula mentioned above. All you need to do is remember the following steps:

  • The first step that you need to follow is to identify the original number and the new number correctly.
  • Then, put the numbers into the formula.
  • The next step requires subtracting the original number from the new number.
  • Then you would have to divide the result by the original number.
  • Then comes multiplying. Multiply the result by 100 and voila! The answer you get is the rate of percentage increase.
  • Last but not the least, if you want to be sure whether it’s correct or not, check your answer using a calculator.

Steps to Calculate Percentage Increase over time

  • To calculate the percentage increase over time, the first thing that you need to do is divide the larger value by the original value.
  • Then, deduct one from the result you got from the first step.
  • Multiply this new number by 100. The result you will get is the percentage change.
  • Now divide this result by the difference of period time between the numbers.
  • The result you get is the percentage increase over time.

Steps to Add A Percentage Increase to A Number

  • The first step requires dividing the number you want to increase by 100.
  • Then multiply 1% by the percentage that you chose.
  • Add the result to the original number and you are all set!

Steps to Calculate An Average Percent Increase

  • First, you would have to calculate all the individual percent changes.
  • Then, Sum all of the individual percentages.
  • Divide the result you got by the number of years, events, trials, etc and there you go!
