Percent increase formula

A = old value

B = new value

C = percent change

C = [ (B-A)/A ] * 100%

Example:

Lets say we start at A = 10 and increase to B = 15. The percent change would be...

C = [ (B-A)/A ] * 100%

C = [ (15 - 10)/10] * 100%

C = (5/10) * 100%

C = 0.5 * 100%

C = 50%

The positive C value means we have a percent increase. Going from 10 to 15 is a 50% increase.
