Use this to calculate the potential change or savings in fees you can offer to a merchant or customer. For example, on a customer's electric bill, the current administration fee might be $7.50 and the offered rate might be $5.00. The calculated savings would be 33%.
The Percentage Change (savings) Calculator (% change calculator) will quantify the change from one number to another and express the change as an increase (savings) or decrease (loss).
This is a % change calculator. From 10 apples to 20 apples is a 100% increase (change) in the number of apples.
This calculator will be most commonly used when there is an “old” and “new” number or an “initial” and “final” value. A positive change is expressed as an increase amount of the percentage value while a negative change is expressed as a decrease amount of the absolute value of the percentage value.
You will generally use the percent change calculation when the order of the numbers does matter; you have starting and ending values or an "old number" and a "new number."
