I retired at 56 with a pension and 33 years paying into SS.

Social security assumes a 40 year work life. The rough calculation for my SS is 33/40 of what I would get if I had worked until 62.

“Social security assumes a 40 year work life. The rough calculation for my SS is 33/40 of what I would get if I had worked until 62.”

For me 62 is next year. However, I am in a good job so I am trying for 67. If my company mandates anything, 62 it is.
