## What is Percentage Decrease?

Percentage decrease is a measure used to express the relative reduction in a value from its original or previous state as a percentage. It is commonly used to quantify how much a quantity has decreased or to compare two values in terms of their relative decline.

## All Formulae Related to Percentage Decrease

Percentage decrease is a measure used to calculate the relative reduction in a value compared to its original or previous state as a percentage. The formula for calculating percentage decrease is as follows:

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

Where:

• Percentage Decrease: The percentage by which the value has decreased.
• Old Value: The initial or previous value.
• New Value: The updated or current value.
• The absolute value (denoted by | |) is used to ensure that the result is always positive. A positive percentage decrease indicates a reduction in the value, while a negative percentage decrease would imply an increase.

Here are some additional formulae and variations related to percentage decrease:

1. Percentage Decrease from Original Value:
• To calculate the percentage decrease from the original or old value to the new value, use the formula provided above.
2. Percentage Decrease from Current Value:
• To calculate the percentage decrease from the current or new value to the old value, you can use the following formula:
Percentage Decrease = [(New Value – Old Value) / |New Value|] x 100%This formula gives you the percentage by which the value has decreased from the current value.
3. Percentage Increase as a Negative Decrease:
• In some cases, you may encounter data where a “negative decrease” implies an increase. In such situations, you can use the following formula to calculate the negative percentage decrease (which represents an increase):
Negative Percentage Decrease = -Percentage DecreaseThis formula allows you to convert a percentage decrease into a negative value to indicate an increase.
4. Percentage Decrease in Consecutive Values:
• To calculate the percentage decrease between consecutive values in a time series (e.g., month-to-month or year-to-year decrease), you can use this formula:
Percentage Decrease = [(Old Value – New Value) / |Old Value|] x 100%In this formula, the “Old Value” represents the value from the previous time period, and the “New Value” is the value from the current time period.
