Percentage Change Formula
((Final Amount - Initial Amount) / Initial Amount) × 100
Example: An investment increasing from $100 to $120 represents a 20% gain.
Loss Recovery Formula
(Percentage Loss / (100 - Percentage Loss)) × 100
Example: If an investment falls by 50%, it must increase by 100% from its reduced value to break even.
