This calculator will help you to determine how much money you need to invest on a monthly basis now, in order to be able to pay for your child's college education by the time they are ready to start college. The calculator allows you to choose between In-State and Out-of-State, between Resident and Commuter and between Public or Private -- and adjusts the estimated costs according to those selections. The calculator also adjusts the future cost of attending college based on your own estimated rate of inflation.
