Formula Behind the Calculation
The calculator works using a simple formula:
Percentage Change = ((New Value − Original Value) ÷ Original Value) × 100
This formula determines whether the result is positive (increase) or negative (decrease).
Example Calculations
Example 1: Price Increase
- Original Value = $100
- New Value = $150
Change = 150 − 100 = $50
Percentage Change = (50 ÷ 100) × 100 = 50% Increase
Example 2: Price Decrease
- Original Value = $200
- New Value = $150
Change = 150 − 200 = -$50
Percentage Change = (-50 ÷ 200) × 100 = -25% Decrease
Example 3: Business Growth
- Original Revenue = $5,000
- New Revenue = $6,500
Change = $1,500
Percentage Change = 30% Growth
