Percentage FAQ

How do I calculate percentage increase?
Percentage increase = ((new value - original value) / original value) × 100. For example, if a price goes from $80 to $100, the increase is ((100-80)/80) × 100 = 25%.
How do I find what percentage one number is of another?
Divide the part by the whole and multiply by 100. For example, to find what percentage 25 is of 200: (25/200) × 100 = 12.5%.
