I just played around with the calculator, and it looks like for salary, the points are:
0 points for less than 25,000
5 points for 25,000 to 29,999
15 points for 30,000 to 34,999
20 points for 35,000 to 39,999
25 points for 40,000 to 49,999
30 points for 50,000 to 54,999
35 points for 55,000 to 64,999
40 points for 65,000 to 74,999
45 points for 75,000 to 149,999
75 points for over 150,000
