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 2014 became $2,034 gross with the 1.7% adjustment — a rise of +$34. After the premium went from $104.90 to $104.90, the payment rose +$34, an effective 1.79%.
| 2014 | 2015 | |
|---|---|---|
| Gross monthly benefit | $2,000 | $2,034 |
| Part B premium | $104.90 | $104.90 |
| Net payment | $1,895 | $1,929 |

The 2015 income-related tiers
Anyone whose modified adjusted gross income on the 2013 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 | $104.90 |
| $85,001 to $107,000 | $170,001 to $214,000 | $42.00 | $146.90 |
| $107,001 to $160,000 | $214,001 to $320,000 | $104.90 | $209.80 |
| $160,001 to $214,000 | $320,001 to $428,000 | $167.80 | $272.70 |
| $214,001 and above | $428,001 and above | $230.80 | $335.70 |
