That seems to be a reasonable age assumption - I’ve heard similar figures elsewhere.
My full retirement age is 66 and 10 months. I have a silly idea that I’ll die at 75, as each of my parents did. To be fair, I’m unlikely to go from what killed either of them (never smoked, don’t have a prostate) but I have other health issues.
Neither my husband nor I work PHYSICALLY strenuous jobs, but we’re just tired of the whole rat race. And I do worry that by the time we have the free time to, say, travel, we won’t be in any shape to do so.
One argument for continuing to work is that every year I delay taking Social Security is a year where I have my full income, as opposed to my SS benefit which would be about 1/3 of that. And when we DO retire, our expenses really will not drop appreciably unless we move to someplace smaller / cheaper - we both telework, so clothing expenses are a nonissue, we only own one car (well, two, but the second one is nominally my son’s), which needs fuel only every month or so.
Continuing to work only bumps up my SS benefit a few dollars a month for every additional year. Not nearly as much as the difference made by delaying TAKING the benefit, e.g. if I retired now and waited 3 years to take it. My husband’s work makes a bigger difference (though I have not crunched the numbers); his salary has gone up a lot faster than mine (after a few years of earning quite a bit less than I did).
The project I’m on has a contract recompete about the time I turn 65. I’ve just about decided that if we don’t win the recompete, that’ll be it for me.
Health insurance is the big kicker for us too. I’m just over a year away from Medicare eligibility; my husband is just a couple months more than that. In either case, we could COBRA our health insurance to cover the gap. A close friend is doing exactly that - she’s my age, and is retiring in another month or so. In her case, she never married, had no kids, and now owns her condo free and clear - so she’ll likely have MORE disposable income than she did 6 months ago.
We were in Florida selling our condo a couple months back. It was small, but with some major downsizing we could certainly have lived in it. It was quite sobering to realize that had we kept it, we could have afforded to retire right away (once we sold the place we live in). But… Florida!
My older brother just snuck in under the wire for an option that is no longer available to anyone younger than him (born 1953 or earlier, I think). He was able to claim under his (ex) wife’s coverage, and receive half her benefit, while waiting until 70 to claim on his own. He was still working part time until quite recently - so between that and his own investments, he was doing fairly well. I gather his income will go up once he claims under his own, later this year, since he will be getting it at age 70.
In general though, waiting until 70 seems like it’ll be tough to have that pay off in the long run - especially if you go with the assumption that you’ll use your own retirement assets to live on until then. You can leave your assets to your heirs. You can NOT leave your unused SS benefits to your heirs.
