Figure the FAFSA EFC for parent income and assets. Then divide by two, then add to that the asset contribution of the student.
Since both had income lower than $6,840, that didn’t add to the EFC. One will add $240 and the other $210 from assets (20% of $1,200 or $1,050) to arrive at each individual EFC.
Something else must have happened to add $1,000 to the EFC of only one student.
Did they both indicate 2 students in college? Did they both indicate the same household size? Do they both have the same income from work for both parents?
If the parents had to list asset amount (over asset protection amount or state requires it, no simplified needs etc), are those amounts the same on both FAFSAs?
