Percentage increase/decrease calculation

The percentage increase/decrease from initial 值 (Vinitial) to final 值 (Vfinal) is equal to the initial and final values difference divided by the initial 值 times 100%:

percentage increase =
Vfinal - VinitialVinitial
× 100%

Example #1

Price percentage increase from initial 值 of $1000 to final value of $1200 is caluclated by:

percentage increase =
$1200 - $1000$1000
× 100% = 0.2 × 100% = 20%

Example #2

Price percentage increase from initial 值 of $1000 to final value of $800 is caluclated by:

percentage increase =
$800 - $1000$1000
× 100% = -0.2 × 100% = -20%

So

percentage decrease = 20%

Difference and final 值 calculation

The difference d is equal to the initial 值 Vinitial times the percentage increase/decrease p divided by 100:

d = Vinitial ×
p100

The final 值 Vfinal is equal to the initial 值 Vinitial plus the difference d:

Vfinal = Vinitial + d
