Percentage Increase Calculator is an online tool for calculating percentage change (increase or decrease) between two values. Formula: ((new-old)/old)×100%. Supports increase/decrease modes, processing speed <5ms.
Increase percentage = ((new value - old value) / old value) × 100%. Example: old=100, new=120, increase = ((120-100)/100)×100% = 20%. Negative result indicates decrease.
Yes. When new value is less than old value, automatically shows as decrease percentage (negative). Example: old=100, new=80, change = ((80-100)/100)×100% = -20%, meaning 20% decrease.
