I lived on savings and then took SS at 62. I did not do it lightly, I would have had to wait until age 67, not 65 to get the max and I would have had to borrow money to live on, this way, my savings give me a cushion for a good life. I did the math and took my pension at 62 as well, also a good idea. You have to not only calculate the money difference but what it would cost you in loss of interest on savings. Now I am crying as my savings is aging out of the 5+ percent I had invested them in several years ago, but eh. would happen no matter what. i did get the interest on the money all those years. it is not you would have gotten x much in so many years, but x much plus interest - so it's more like 85 is the break even year. No one in my family has lived that long.
I lost 15% on my pension, but as I said, it paid off. Now the stupid company is trying to get me to take a lump sum and I am refusing, ha ha . But they may win eventually.
ETA - I already died and was resuscitated due to error in a prescription and the instruction on taking it. Thanks Doc, , years before refused to have an anesthesiologist work on me because he looked distracted, got another one, his patient on elective surgery did not come out of the anesthesia. Not sure if she ever recovered because they threw me out of the hospital when they woke me up in the recovery room way too soon by screaming so much, guess they did not want to have a witness, they made me leave the hospital right away instead of the promised 3 hour recovery time. I am living on borrowed time.
