Adding…if the net price calculator specifically asks for incomes from step parents and non-custodial parent, it might….might be a decent estimate. Most NPCs do not do this.
With a step parent with $250,000 in income, it’s unlikely you would qualify for need based aid anywhere on this list of schools.
The schools that use the FAFSA only won’t consider the income from the parent you don’t live with this year. But those schools don’t meet full financial need.
The parent info will be changing for divorced families likely for the 2023-24 school year. When this happens, the FAFSA will be asking for the parent who has the higher income. But in your case, it sounds like either way, you are looking at parents income that is in the $250,000 a year range.
You need to look where you will have either a guarantee or strong chance for merit aid as family finances don’t factor into this.
