274% and FIREd.
Wow, @secondcor521 ! 274%!!! Did you fire some years back and your stash has grown in the bull market?
I retired in February 2016. There are several reasons for the large number.
First, I hit my FIRE number somewhere in 2014 but was still enjoying the job and liked the additional safety factor, so I kept working another two years.
Second, I made a conservative assumption that I would earn no money (except portfolio income like dividends) after FIRE. This has not been the case - I currently receive about 1.25% of my FIRE stash in what I call non-portfolio income - this directly reduces my WR.
Third, as you note, I retired at a fortunate time vis-a-vis the markets. My portfolio, which is mostly VTSAX, is up perhaps 25% since I retired.
Fourth, I've found that some of my spending was stress-related. As I FIREd and my stress level dropped, the spending associated with that stopped as well.
Fifth, now that I'm FIREd I can optimize some of my spending even more just because I have the time to do so. I don't need to, but it's a game I like to play. For example, I flew to my sister's house for Thanksgiving. The flight back home on a Monday would have been about $300. I stayed until Wednesday since I didn't have to be back at work and flew home for about $50. My auto insurance has dropped since the miles I drive are fewer. My utilities should drop over time as I do home improvement projects such as improve the insulation and so forth.
As a general rule, I'm extraordinarily conservative and enjoy not spending money probably more than I enjoy spending money most of the time. I also claim to be nervous about my three kids' college expenses that are coming up over the next several years, but that may turn out to be an excuse to be uber safe. Finally, I am unimaginitively boring, so paying $1 or $2 to play bridge for an afternoon or $5 for a Starbucks coffee is my idea of blowing dough.
