如何计算Percent Change

learn.whatIsHeading

A percentage change calculator computes the relative increase or decrease between two values: percent change = (new − old) ÷ old × 100. A stock rising from $50 to $65 increased by 30%; the same stock falling from $65 back to $50 dropped by only 23.1% — asymmetry that trips up many investors.
