Thanks to the Percentage Decrease Calculator, you can easily find out the increase from one value to another in terms of a percentage.

## How to use the Percentage Decrease Calculator?

- Write the Starting value in the first field (after “from”).
- Write the Ending value / Final Value in the second field (after “to”).

The Percentage Decrease Calculator immediately shows the percentage decrease result. If the value is negative then there was an increase, if it’s positive, then there was a decrease.

## How to calculate percentage decrease?

Here is the step-by-step guide on how to calculate percentage decrease:

- Subtract Starting value minus End value
- Divide that amount by the absolute value of the Starting value
- Multiply by 100 to get percent decrease value

Percentage Decrease = ((Starting Value – End Value) / abs(Starting Value))*100%

If the percentage is positive, it means that there was an increase not a decresae.

## Some other examples of percent changes:

A decrease of 100% in a quantity means that the final amount is 0 % of the initial amount (100% of initial – 100% of decrease = 0% of initial).

## Example of percentage decrease calculation

In the last month you saw a T-Shirt for $35 but now it’s on sale and the price is $21. Let’s calculate the decrease.

Percentage decrease= ((34 – 21) / abs(35))*100% = (14/35)*100% = 40%

So the price of the T-shirt you would like to buy is decreased by 40%.
