Calculating 20% of a number gives you only that portion of the number. For example, 20% of 100 is 20. Increasing by 20% means adding that percentage to the original number. If you increase 100 by 20%, you get 100 + 20 = 120. They're different concepts: one tells you how much the part is, the other tells you the total after the increase.
