Social Security Benefit Detailed Calculator (USA)

The Social Security Benefit Calculator produces the Social Security benefit for an old-age, survivor, or disability claim, given the characteristics of a particular worker (such as birth date, past earnings, and type of benefit). It also produces the "primary insurance amount" (PIA), "maximum family benefit", the actuarial reduction or increment factor (for early or delayed retirement), and the monthly benefit amount (MBA). The calculator can produce a benefit for any historical case from the first Social Security benefit paid (1940). It can also produce a projected benefit, based on standard or user-specified assumptions, through 2095.
