Percentage Change Calculator
Top

Percentage Change Calculator (or Percent Difference Calculator or Percentage Difference Calculator) is an online tool to find the percentage difference between the original value and the changed value (or new value).

Enter original value in this calculator as V1 and the changed value as V2, and click solve. It will calculate the difference between them, percentage difference between them and will tell whether it is percentage increase or percentage decrease.

Difference between the values is calculated as -
(Bigger value among V1 & V2) - (Smaller value among V1 & V2) = mod of (V1 - V2)

Percentage Difference (% difference) between the values is calculated as -
(Difference between the values) / Original value = (mod of (V1 - V2)) / V1

If changed value, V2 is smaller than original value, V1, it is a percentage decrease. If changed value, V2 is greater (bigger) than original value, V1, it is a percentage increase.

If changed value, V2 is same as (equal to) the original value, V1, then it is no change.
