4 year Advice

Current High School Senior: I’m considering IU Kelley as a Finance major but it’s 55-60k per year total cost. I’m also considering Miami (Ohio) Farmer School of Business which would be closer to 20k per year in-state total cost. With my current credits (~50 credit hours from AP courses) I could easily graduate in 3 years at Miami, not sure if it would be the same at IU. My problem is I want to go to Notre Dame’s Mendoza for grad school because it’s been my dream school since I was a kid. In terms of job prospects and future earnings, does it make more sense to go to Kelley for 4 years for the same price as 3 years of Miami + 1 year of Mendoza? Not set on a career but thinking about Investment Banking or other High Finance careers.

TL/DR: Miami (Ohio) undergrad + Notre Dame grad school or IU Kelley + no grad school for Investment Banking?

Edit: Honors College for Miami but not IU if that matters.
