FAFSA EFC only really matters for federal or state aid. Once the EFC is around $6,000 there is no Pell Grant, and depending on school/state there might or might not be federal work study or state grant.
Very few schools meet need based on FAFSA EFC alone.
2019 is almost 3/4 over.
FAFSA doesn’t look at primary home equity.
You can try to update the old spreadsheet with the new EFC formula values, or work through the 20/21 FAFSA EFC formula by hand.
