Formula Used in Added Percentage Calculator
Understanding the formula helps you better interpret results.
1. Percentage Increase Formula
When a value increases:
Formula:
Percentage Change = (Added Value ÷ Original Value) × 100
Final Value:
Final Value = Original Value + Added Value
Example (Increase)
Original Value = 1000
Added Value = 200
Step 1: Percentage Change
(200 ÷ 1000) × 100 = 20%
Step 2: Final Value
1000 + 200 = 1200
2. Percentage Decrease Formula
When a value decreases:
Formula:
Percentage Change = (Added Value ÷ Original Value) × 100
Final Value:
Final Value = Original Value − Added Value
Example (Decrease)
Original Value = 1000
Added Value = 150
Step 1: Percentage Change
(150 ÷ 1000) × 100 = 15%
Step 2: Final Value
1000 − 150 = 850
