The Percentage Increase Calculator

How to use a Percentage Increase Calculator in

The online percentage increase calculator computes percentage increases, growth rates, and price increases in percentages. You can use it to track financial growth, analyze market trends, or if you are curious, understand how numbers change. 

While it plays a significant role in mathematical calculations, the growth calculator is handy in science when calculating the percent increase in the mass of a chemical element in a compound.

Using Increase Calculator

The percentage increase calculator calculates how much a value has grown compared to its Starting Value. The results are expressed as a percentage to indicate the changes in that specific context.

To use the percentage increase calculator, enter starting value and final value. The calculator will then instantly calculate the percentage increase. 

How to Calculate Percentage Increase

Here is the complete percentage increase formula:

Percentage Increase =(Final Value - Starting Value) / Starting Value * 100

Let’s have a look at an example using the growth calculator: 

Suppose a product's price was $50, and it increased to $60. Calculate the percentage increase.


  • Enter the Starting Value ($50) in the calculator 

  • Then enter the Final value ($60)

  • Tap on the “Calculate” Button

  • The calculator generates results as 20%

If we were to use the manual approach:

Percentage Increase 

Final value - Staring value


($60 - $50)

($10/$60) *100

% Increase


How to Calculate a Percentage Decrease

The formula to calculate the percentage decrease changes slightly to avoid calculation with the negative sign after subtraction.

Percentage Decrease =(Starting Value - Final Value) / Starting Value * 100

Suppose the price of a product was $100 last month, and this month it is selling for $80. Calculate the percentage decrease in price.

  • Enter the Starting Value ($100) in the calculator 

  • Then enter the Final value ($80)

  • Tap on the “Calculate” Button

  • The calculator generates results as 20%

The price of the product has decreased by 20% this month.
