<prompt> Human: Hi PF,My wife and I need help budgeting for college education in 20-25 years. We have 0 kids now but expect to have 2 in the next 4-5 years. One thing that baffles me is how to plan for their education.With investing, I know time is money but just how much should we budget for college seeing that theyre 25 years from college graduation. Do we think 7-8 increases will hold forever like they have the past decade?We ideally want to have in-state California college tuitionfoodbookshousing all taken care of for both kids. We are in our late 20s and make very good money. Our undergrads were mostly paid for by parents and we believe its only fair that we pay it forward to our kids. We didare putting ourselves through grad school.What we estimate to cost 100K now with a 3 increase should cost 200K when theyre ready. At 7-8 that number would be 500K!?  <response>: No one has any idea. Its all just guessing.
