About This Calculator
The Percentage Change Calculator quickly shows the percentage increase or decrease between two price points. This is essential for tracking investment performance, comparing portfolio values, and making quick trading decisions.
How It Works
- Old Price: Your entry price or previous value
- New Price: Current price or exit value
- Formula: ((New - Old) / Old) × 100
- Positive values: Indicate profit or gain
- Negative values: Indicate loss or decline
Quick Reference
- 50% gain requires 100% gain to double
- 50% loss requires 100% gain to recover
- 2x = 100% gain, 3x = 200% gain, 10x = 900% gain
