The formula for percentage change

% Change = ((new value – original value) × 100) / original price

There are two types of the percentage change. They are

  1. Percentage increment
  2. Percentage reduction

Percentage increment

When the new price is greater than the original price, the percentage change in price indicates the percentage increase from the original number, so that:

Percent increase (% increase) = original price / value x 100 increase

Where price increase = new value – original price

Percentage reduction:

When the new price is less than the original price, the percentage change in price represents a percentage less than the original number, so that:

Decreasing percentage (decreasing%) = decrease in original value / value x 100

Where Price Reduction = Original Price – New Price

Also check: Percent increase and decrease
