Calculator for Obamacare Insurance Premiums

From NPR:

Nearly all Americans starting Jan. 1, 2014, or else they'll be liable for a tax penalty. If you've asked yourself, "How much will Obamacare cost me?"  We can help you find the answer.

A calculator produced by the Kaiser Family Foundation in collaboration with NPR allows shoppers to find out if they qualify for subsidized insurance coverage or Medicaid. Enter your ZIP code, income, age, family size and a few other factors into the calculator to get subsidy estimates and insurance premiums available for coverage sold on the marketplaces, or exchanges, once enrollment begins.

The calculator makes use of premium data from 46 states plus the District of Columbia. The remaining four states (Kentucky, Massachusetts, New York and Vermont) either set premiums using different formulas or haven't provided data yet.
