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:
- 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.
- 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 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):
- 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:
