Once you have worked through all of the mathematics and arrived at a primary insurance amount, including cost-of-living increases, the next step is to convert it to a benefit, either for the worker, for a dependent, or for a survivor.rnThe worker's benefit. The old-age benefit of a worker who has reached full retirement age (65 for those bom prior to January 2, 1938, but age 66 for those who attain age 65 in 2008, i.e., those bora between January 2,1943 and January 1,1944) will be approximately the same as his or her PIA, but the benefit will be reduced for every month in which benefits are paid prior to full retirement age. Note that no worker attaining age 65 in 2008 will attain full retirement age in 2008. The only workers attaining full retirement age in 2008 are those who attained age 65 in 2007 and attain the full retirement age of 65 and 10 months in 2008.
