1. Calculate the End Value
decreased by a percentage of its Initial Value
End Value =
715,000 - Value of Percentage Decrease =
715,000 - (30.7% × 715,000) =
715,000 - 30.7% × 715,000 =

495,495
2. Calculate the absolute difference between the End Value and the Original Value
The Absolute Difference =
End Value - The original value =
495,495 - 715,000 =
- 219,505
3. Value of Percentage Decrease
It can be calculated in two ways.
The first method:
Value of Percentage Decrease =
Percentage of the Decrease % × The original value =
30.7% × 715,000
The second method:
Value of Percentage Decrease =
The original value - New Value
Value of Percentage Decrease =
219,505
The end value: 715,000 decreased by 30.7% percent = 495,495
The Absolute Difference = - 219,505
