Percentage change calculation

The percentage change from old value (Vold) to new value (Vnew) is equal to the old and new values difference divided by the old value times 100%:

percentage change = (Vnew - Vold) / Vold × 100%

Example #1

Price percentage increase from old value of $1000 to new value of $1200 is caluclated by:

percentage change = ($1200 - $1000) / $1000 × 100%

 = 0.2 × 100% = 20%

Example #2

Price percentage decrease from old value of $1000 to new value of $800 is caluclated by:

percentage change = ($800 - $1000) / $1000 × 100%

 = -0.2 × 100% = -20%
