I'm still working, at the age of 54, and hoping to go out at 55. I think I've probably gone overkill with how much I've saved up, and could probably have retired a couple years ago. But I fell into the OMY (One More Year) Syndrome trap. It's just that the job is easy, flexible, and fairly low stress (although it does annoy me from time to time)
FireCalc gives me a 100% chance of success, at the annual rate I think I'll be comfortable with. And the annual rate I've picked is well above my current take-home pay, and I have trouble even spending that!
Even bumping up my annual withdrawal rate by 50%, I'm still at 99.1% success, and at 62.5% above, I'm at 94.4%. I didn't bother calculating any annual withdrawal rates any higher than that, because I can't imagine spending that much money. At least, not consistently.
As for inflation, I do worry about it, and gripe about it from time to time, but it doesn't keep me up at night. The big things that have jumped lately are homeowner's insurance, electricity, and groceries. Well, and gasoline. But, those are relatively minor expenses overall. I locked into a 30 year fixed mortgage at 2.875% back in 2020, so my mortgage is fairly low, especially by today's standards. So I'm set, on the housing front, which is a good thing. If I was in the market for a home, I think I'd be worried.
Cars are expensive, but I think adjusted for inflation, they're really not that bad when you factor in all the standard equipment and technological advances. And, I don't see myself needing a new car anytime soon.
As for that "retired, broke, or dead" calculator, I have a feeling I'll be one of those who ends up with "too much" money, if there is such a thing, when I do finally kick off, but right now I feel comfortable with it. And I'd rather have too much, than not enough!
