# Percentage Decrease Calculator

By Mateusz Mucha and Dominik Czernia, PhD candidate

The percentage decrease calculator determines the change from one amount to a lesser amount in terms of percent decrease. It is important to understand how to calculate percent decrease manually using the percent decrease formula. The content below will explain these concepts in further detail.

## How to calculate percent decrease

1. Suppose original value is `750` and new value is `590`. Input this into the formula below.
2. Perform the operation `750 - 590 = 160`.
3. Divide `160` by `750` to get `0.213`.
4. Multiply `0.213` by `100` to get `21.3` percent.
`Percent decrease = [(original_value - new_value)/original_value * 100]`
