The Percentages Calculator to find the amount of chang, Value after Increase and Value after decrease.
Amount of change = Original value * Percentager change%.
Value after INcrease = Original value + Amount of change.
Value after DEcrease = Original value - Amount of change.
For example, Original value = 100, Percentage change = 1, Amount of change = 100*1% = 1.
Value after INcrease = 100 + 1 = 101, Value after DEcrease = 100 - 1 = 99.
