Your son isn’t graduating from high school until 2028. The net price calculators are currently set up for students graduating in 2026, and that’s not you.
The 2028-2029 academic year financial aid will use 2026 tax year income information, and that year hasn’t even started yet.
Please use these NPCs as a very gross estimate for a 2028 grad. Financial aid policies and awarding formulas do sometimes change.
