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 2012 became $2,034 gross with the 1.7% adjustment — a rise of +$34. After the premium went from $99.90 to $104.90, the payment rose +$29, an effective 1.53%.

No income-related table is committed for this year
