But I think that’s just it, some people are talking about FAFSA EFC and some are using EFC as a term forthe contributions families need to make.
I don’t think a FAFSA EFC for siblings should vary by more than a few hundred dollars unless one has a huge savings or big time job (actor, model, rock band). My kids’ EFCs were within a few hundred dollars because on had some savings the other didnt.
OP said FAFSA EFC but hasn’t clarified if the difference was off a SAR or generated by the schools.
