Adjusted gross income (AGI) is gross income from taxable sources (including wages, interest, capital gains, income from retirement accounts, alimony received) minus allowable deductions, such as unreimbursed business expenses, some medical expenses, alimony paid, and deductible retirement plan contributions. You calculate your AGI on the first page of your federal tax return and it serves as the basis for figuring the income tax you owe.

A report by Milliman, commissioned by Covered California and released today, shows that those individuals with incomes less than 400% of the federal poverty level purchasing an individual plan next year are likely to pay about 47 to 84 percent less in monthly premiums compared to 2013. These consumers will benefit directly from the federal tax credits that will be available through Covered California. The study also concludes that those earning above 400 percent of the federal poverty level may see a cost increase that would average 20 percent due to increases in their monthly premiums but would be partially offset by reduced out-of-pocket cost. For many individuals facing increased premiums, they could potentially avoid some or all of the potential price increase by shopping for lower priced plans either in Covered California or on the individual market.

Fair share means that even if your income is below 400% of Poverty Level, if you can get the Silver Plan for less than 9.5% of income, you don’t get a subsidy. Cahba.com The Kaiser Foundation Calculator does a pretty good job of showing more detail of how this is calculated.
