Because of a peculiarity in the way Social Security is calculated, you are going to be shorted thousands of dollars' worth of retirement benefits -- unless Congress fixes the new "notch."
Here's the deal: According to the Center for Retirement Research at Boston College, the calculations on which Social Security is based aren't adjusted for inflation or even for an increase in earnings for people between the ages of 60 and 62. Most of the time that doesn't make any difference, but if you were born in 1947, you entered that hiatus in 2008, the year that Social Security recipients got a record-high 5.8 percent cost-of-living increase -- payable in January 2009 -- followed by two years of no increases.
Missing the increase means that people born in 1947 fall permanently behind. The center calculates that an average couple born in 1947 and claiming Social Security at 62 would receive a monthly payment of $2,374, $749 per year less than they would have received if they had been born in 1946. If they survive to 83, which is how long Social Security's actuaries think they'll live, this couple will get nearly $12,729 in lifetime benefits less than they would without this "notch."
Center researcher Andrew Biggs, who was previously the principal deputy commissioner of the Social Security Administration, recommends a quick fix. He would make benefits for those born in 1947 comparable to what those born in 1946 get by giving the 1947 crowd a 3.5 percent immediate raise. At the very least, he would give them a 2.7 percent increase, which would keep them in line with the amount received by those born between 1930 and 1946.
