百分比增长计算器

计算从初始值（旧值）到最终值（新值）的百分比增长：

最终值 calculator

计算最终 (new) value from 初始 (old) value and percentage increase:

从初始值（V_初始）到最终值（V_最终）的百分比增长/减少等于初始值和最终值的差值除以初始值乘以100%：

百分比增长 =

V_最终 - V_初始V_初始

× 100%

Price percentage increase from 初始 value of >Price percentage increase from 初始 value of 000 to 最终 value of $1200 is caluclated by:

百分比增长 =

>200 - >000>000

× 100% = 0.2 × 100% = 20%

Price percentage increase from 初始 value of >Price percentage increase from 初始 value of 000 to 最终 value of $800 is caluclated by:

百分比增长 =

$800 - >$800 - 000>000

× 100% = -0.2 × 100% = -20%

所以

百分比减少 = 20%

The difference d is equal to the 初始 value V_初始乘以百分比增长/减少 p 除以 100：

d = V_初始 ×

p100

The 最终 value V_最终 is equal to the 初始 value V_初始加上差值 d：

V_最终 = V_初始 + d
