1,000,000,000,000 - (- 14.2% × 1,000,000,000,000)
1. Calculate the End Value
decreased by a percentage of its Initial Value
End Value =
1,000,000,000,000 - Value of Percentage Decrease =
1,000,000,000,000 - (- 14.2% × 1,000,000,000,000) =
1,000,000,000,000 + 14.2% × 1,000,000,000,000 =

114.2 × 1,000,000,000,000 ÷ 100 =
114,200,000,000,000 ÷ 100 =
1,142,000,000,000
2. 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 =
- 14.2% × 1,000,000,000,000
The second method:
Value of Percentage Decrease =
The original value - New Value
Value of Percentage Decrease =
- 142,000,000,000
The value of the decrease is negative, so we are actually dealing with a Percentage Increase.
The end value: 1,000,000,000,000 decreased by - 14.2% percent = 1,142,000,000,000
Value of Percentage Decrease = - 142,000,000,000
