<p>People say that it goes up a bit with 2 in college, but not double. So $45K might go up to 50-55K to be split. I don’t know this from experience, just going by what others say. </p>
<p>I think the lower contribution for 2 or more children is in consideration of the extra costs involved with raising the extra child, or maybe because of all the extra money you have to set aside for college for more than one?</p>
<p>I looked for tables, thinking that though of course any 2D table would have to fix all the ‘extras’ at zero, at least it gives a starting point for understanding it.</p>
