Another little known social security / Medicare issue. In 2009 the Medicare part B premium that seniors pay as their share of the Medicare insurance was $96.40 (for most people), in 2010 that premium was raised to $110.50, and in 2011 it will be set at $115.40. However those increases were not passed on to seniors because there was no social security COLA in 2010 or in 2011. If by chance there is a Social Security COLA in 2012, the first $19.00, plus what ever the 2012 increase is, will be immediately eaten by those premiums.
Whatever it goes up will be rolled in to what the next cola % is based on. Just like savings with compounded interest.
