Percentage Value = (Percentage ÷ 100) × Number

= 120

Percentage = (Part ÷ Total) × 100
Example:
40 out of 200:
(40 ÷ 200) × 100
= 20%
Result:
40 is 20% of 200
Formula 3: Percentage Increase
Formula:
Percentage Increase = ((New Value - Original Value) ÷ Original Value) × 100
Example:
Original value: 100
New value: 150
Increase:
((150 - 100) ÷ 100) × 100
= 50%

Formula:
Percentage Decrease = ((Original Value - New Value) ÷ Original Value) × 100
Example:
Original value: 500
New value: 400
Decrease:
((500 - 400) ÷ 500) × 100
