<p>"if one were to assume an EFC of $40k for child 1, and child #2 goes to college in 2 year, it appears the total EFC generally remain @ $40k. Thus, FA Aid assistance for Child 1 might double to offset the increased burden of the family for 2 tuitions. Is this generally accurate."</p>
<p>No-</p>
<p>While the combined EFC's for the two kids will probably remain near 40K (assuming similar parental financial situation, and as violadad said similar finances between the two kids), that doesn't at all mean that the FinAid package for Child #1 will double. The financial aid package could go up much more than double the initial package.</p>
<p>Here's why. With an initial (relatively high) EFC of 40K for kid #1, and only one in college, your "need" will be relatively low (say for a school with a Cost Of Attendance of 45K, your need will be only 5K). So a school that meets 100% of need (many don't) might offer a financial aid package (grants and loans) of 5K.</p>
<p>Now, with two in college, Kiddo #1's EFC might be around 20K (and ditto Kiddo#2, so you still end up with a combined family EFC of around 40K). BUT kiddo #1's need is now 45K minus 20K or 25K, a fivefold increase. So if the school meets 100% of need (again, many don't), they might offer a financial
aid package (grants and loans) of 25K, or 5 times the financial aid offered the previous year.</p>
<p>Conversely, in a situation where a family has a very low EFC and a relatively high need with child #1, say an EFC of 5K and need of 40K, when child #2 comes into the picture, the EFC for child #1 may drop to around 2.5K resulting in only a minor change in need, and a minor change in the aid package (obviously, the aid won't double to 80K a year). :) </p>
<p>"My fear is accepting an EFC for Child 1, only to find out that 2 years down the road colleges now expect us to come up with an EFC of 2x."</p>
<p>No-- two years down the road, other things being equal, your family EFC (the two kid's EFC added together) should be similar to the current EFC for the one child. The forumulas adjust for the number in college so that a family with 3 in college concurrently isn't assumed to be able to pay 3X what they would pay with just one in college.</p>
