What is the Percentage Increase Calculator?
The Percentage Increase Calculator computes the exact percentage growth from a starting value (V₁) to a higher ending value (V₂), or increases a base number by a specified percentage rate. It uses the growth formula: Percentage Increase = ((New Value − Original Value) ÷ |Original Value|) × 100.
It also displays the absolute unit gain (New Value − Original Value) and growth multiplier.
Formula: ((New Value − Original Value) ÷ |Original Value|) × 100
Example: A salary increase from $60,000 to $69,000 is ((69,000 − 60,000) ÷ 60,000) × 100 = +15% increase.

Calculation Notes
Helpful tips:
- • Doubling and Tripling in Percentages:Doubling a value is a 100% increase (× 2), while tripling a value is a 200% increase (× 3).
- • Non-Zero Baseline Required:Calculating percentage growth from a starting value of 0 is mathematically undefined.
