You can check net price calculators on various colleges’ web sites to see what financial aid may look like, then compare the results with what your parents will pay.
Note that while UCs, CSUs, and many other colleges will base financial aid only on your custodial parent finances, some colleges (e.g. USC, Pomona) require both parents’ finances. Check the financial aid web pages of the college carefully so that you know whether to include both parents’ finances in the net price calculator.
