I wrote a post last month about the then-soon-to-be-available net price calculator, an online tool that estimates your financial aid eligibility, subtracts that from the sticker price of your chosen college, and estimates how much you will need to pay to attend that school next year. The federal government has mandated that colleges must have the tool available on their websites by October 29, 2011. But if you don’t want to wait until then, the College Board has it available here.
