What is Percentage Increase?

The percentage is used in many settings in order to compare two values. We often have to compare the values of a single variable at two different points or times. Both percent increase and decrease are measures of change in percent, that is the extent to which variable gains or loses intensity, magnitude, extent, or value. Lastly, we get the results by comparing the initial and final values according to a formula.

The term percentage increase is also called percentage change. It refers to the difference between the final and initial values of a quantity. If the percentage increase is a negative value, then we can say that there is a percentage decrease in quantity.

Also, it is very useful in analyzing how the value has changed over time. It is quite similar to an absolute increase. However, the former is more used when comparing multiple data sets.

For example, consider two changes, the first one is from 1 to 51 and another from 50 to 100. Both changes have an absolute change of 50. But the percentage change in the first case is 5000%, while in the second case, it is 100%. Thus, we can say that the first change grew a lot more. Moreover, the percentage increase is the most common way of measuring growth.

How to Calculate Percentage Increase?

The simplest and easiest possible way to calculate percentage increase is to use our percentage increase calculator. Along with that if you wish to learn the standard mathematical procedure to calculate the percentage increase on pen and paper, then follow the method below.

Firstly, let's know the Percentage Increase Formula.

Percentage Increase Formula

% Increase =  
Final - Initial
| Initial |
  ×  100

Now follow the steps below to calculate the percent increase.

  1. Identify the initial or starting value and the final value.
  2. Enter the values into the formula.
  3. Subtract the initial value from the final value and then divide it by the initial value.
  4. Lastly, multiply the value obtained in the previous step by 100.
  5. Finally, the value you get is a percent increase or decrease.
Example 1:

Consider you invest $1000 which is increased to $1500 in a period of one year. Then, as per the method discussed above, the percentage increase of your investment will be:


((1500 – 1000) / 1000) × 100
(500 / 1000) × 100 = 50% (increase)

Let's take one more example of a percentage decrease.

Example 2:

Suppose you invested $1500, whose value after one year decreased to $800, then the percent decrease would be:


((800 – 1500) / 1500) × 100
(-700 / 1500) × 100 = -46.67% (decrease)

% Increase = (Final Number - Starting Number / Starting Number) × 100

  1. Subtract the starting value by the final value and then divide it by starting value.
  2. Lastly, multiply the value that you get from the above step by 100 to get the percentage increase.
  3. If you get the negative value, it means there is a decrease in percentage.
