The Minnesota Health Insurance Exchange, in conjunction with UC Berkeley, has published an individual and family subsidy calculator. It can be located here: Individual and Family Subsidy Calculator
Notes: This calculator shows expected spending for families and individuals eligible to purchase coverage in the Exchange under the Affordable Care Act. Under the law, maximum contributions to premiums will be based on modified adjusted gross income, while estimates in this calculator are based on the annual income entered by the user. Actual premiums in the Exchange are not yet known. The premiums in this calculator reflect national estimates from the Congressional Budget Office for 70% actuarial value plans, adjusted for premium inflation and age rating. Premiums are shown in two tiers: individual and family (two or more family members), though premiums in the Exchange will vary based on additional family tiers which are yet to be determined. Coverage in the Exchange will begin in 2014, but the spending amounts are estimated in 2012 dollars.
