@Madison85 – if the OP uses the Medicare Wages amount from the W-2, that captures 401K contributions.
IRA contributions would needed to be separately added in. (Roth or 401K Roth, of course, would not need to be added at all.)
Harvard’s net price calculator might be easy to use…for students applying to Harvard. But don’t assume that the aid provided at Harvard will be forthcoming everywhere else.
