## About Percentage Decrease Calculator (Formula)

A Percentage Decrease Calculator is a handy tool used to quantify the reduction in a value as a percentage of its original amount. This calculator is invaluable for a wide range of applications, including finance, economics, statistics, and everyday decision-making. It helps individuals and businesses understand how much a value has decreased in relative terms, providing valuable insights for budgeting, financial analysis, and tracking trends.

**Formula for Percentage Decrease:**

The formula for calculating the percentage decrease is straightforward and involves comparing the original value (Old Value) with the reduced or current value (New Value):

**Percentage Decrease = [(Old Value – New Value) / Old Value] x 100%**

Where:

**Percentage Decrease**is the reduction expressed as a percentage.**Old Value**represents the initial or original value.**New Value**is the reduced or current value.

Let’s break down the formula with an example:

Suppose a product initially cost $200 but is now being sold for $160. To calculate the percentage decrease in its price:

Percentage Decrease = [(200 – 160) / 200] x 100% = (40 / 200) x 100% = 20%

So, the price of the product has decreased by 20%.
