You get less than if you worked until age 65 because you obviously aren't paying into it as long. We decided it was worth it to retire younger and be able to collect for more years and enjoy life a bit. He was laid off for several months every winter anyway so his pay actually went up when he retired because he was collecting year round and wasn't spending a fortune on gas/tolls, etc. traveling to Lake County to work all the time. He never had jobs close to home.
For social security.
for my pension, I don't think i'll get less.
