Under the Affordable Care Act, families making less than 400 percent of the poverty level are eligible for a subsidy. That subsidy ensures they don't pay more than 9.56 percent of their income on their premium for a mid-level plan (the second-lowest silver standard plan purchased on the state's insurance exchange); the cap is even lower is you make less. But those making above 400 percent of the poverty level aren't eligible for a subsidy — and for some, especially those making slightly above 400 percent of the poverty level, the same plan will cost substantially more.
Experiment with your family members below, and see how that affects the amount you would pay for a mid-level plan, relative to your income. (Based on Hartford County rates.)
