What Is Percentage Decrease?
Percentage decrease measures the relative reduction between an initial (old) value and a final (new) value, expressed as a percentage. It is widely used in finance, economics, business, and education to analyze reductions or losses.
Formula:
Percentage Decrease=Old Value−New Value / Old Value ×100
Where:
- Old Value = the initial or starting value
- New Value = the final or current value
Example:
Old Value = 500
New Value = 400
500−400 / 500×100=20
The value decreased by 20%.
