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%
