Chance of getting in and merit $?

Has anyone had any experience with receiving significant merit aid and if so, how much? Applied early action with a strong academic record with a 4.0 unweighted gpa, 4.8 weighted, and a 1420 SAT. All Ap and IB classes. Will be graduating with an IB diploma. Is there a chance to be accepted and to get some merit money? Thanks in advance.
