How Percentage Decrease Works
Percentage decrease measures how much a value has fallen compared to its original value.
The formula used is:
Percentage Decrease = ((Original Value − New Value) ÷ Original Value) × 100
For example, if a price drops from $100 to $80:
Decrease = (100 − 80) ÷ 100 × 100
This equals a 20% decrease.
