Social Security retirement calculators can be found online at the official website of the Social Security Administration. A number of different calculators are available, including a retirement estimator, a retirement age calculator and a life expectancy calculator, notes the Social Security Administration.
The retirement estimator calculator helps individuals calculate the amount of monthly benefits they may receive based on their work record, the Social Security Administration explains. The retirement age calculator helps people see the difference in their retirement benefit amount based on different ages of retirement. The life expectancy calculator helps people estimate how long they may live in order to determine how long benefits may last.
