These state-sponsored plans let you exclude your college-savings earnings from federal and state taxes. Says Mark Kantrowitz of FinAid.org: "The long-run return, with the tax savings, typically exceeds the normal 6% to 8% yearly tuition increase."

For calculators to estimate your total costs, as well as details about your state's 529, go to finaid.org and savingforcollege.com. To find out how much a school will cost, use the calculator to the right.

If your local plan charges more than 0.5% a year, consider another state's. (Note that you might lose a state tax deduction on contributions, but this is sometimes worth it.)

Opt for an Illinois or Ohio direct program - both offer investments with low fees and strong management.
