The Social Security Retirement Age. Congressional Research Service. Zhe Li. March 7, 2019
The Social Security full retirement age (FRA) is the age at which workers can first claim full Social Security retired-worker benefits. Among other factors, a worker’s monthly benefit amount is affected by the age at which he or she claims benefits relative to the FRA. Benefit adjustments are made based on the number of months before or after the FRA the worker claims benefits. The adjustments are intended to provide the worker with roughly the same total lifetime benefits, regardless of when he or she claims benefits, based on average life expectancy. Claiming benefits before the FRA results in a permanent reduction in monthly benefits (to take into account the longer expected period of benefit receipt); claiming benefits after the FRA results in a permanent increase in monthly benefits (to take into account the shorter expected period of benefit receipt).
