What it did to a Social Security payment
The Part B premium is withheld from the Social Security payment, so it lands in the same January as the cost-of-living adjustment and the two move against each other. A $2,000 monthly benefit in 2011 became $2,072 gross with the 3.6% adjustment — a rise of +$72. After the premium went from $115.40 to $99.90, the payment rose +$88, an effective 4.67%.
| 2011 | 2012 | |
|---|---|---|
| Gross monthly benefit | $2,000 | $2,072 |
| Part B premium | $115.40 | $99.90 |
| Net payment | $1,884 | $1,972 |

The 2012 income-related tiers
Anyone whose modified adjusted gross income on the 2010 tax return crossed the first threshold paid more than the standard premium. The adjustment is a flat dollar amount per tier, not a percentage of income, and it steps at the bracket boundary rather than phasing in.
| Single | Married filing jointly | Adjustment | Total Part B |
|---|---|---|---|
| Up to $85,000 | Up to $170,000 | none | $99.90 |
| $85,001 to $107,000 | $170,001 to $214,000 | $40.00 | $139.90 |
| $107,001 to $160,000 | $214,001 to $320,000 | $99.90 | $199.80 |
| $160,001 to $214,000 | $320,001 to $428,000 | $159.80 | $259.70 |
| $214,001 and above | $428,001 and above | $219.80 | $319.70 |
