What is Percentage Decrease?

A percentage decrease is basically how much a number has gone down, shown as a percentage of where it started. 

Formula,

Percentage Decrease = ((Original Value − New Value) / Original Value) × 100

Example, A product’s price falls from 500 to 350. Subtracting gives 150, and dividing 150 by 500 gives 0.3. Multiply that by 100 and you get a 30% decrease.
