I was already not working when I made the decision to FIRE. MegaCorp fired my sorry ass at 58 yrs old so I went from full employment one day to unemployed the next. In fact, 17 years later, I still consider myself "long term unemployed" wherever and whenever that status is to my advantage
. My DW was already retired at the time.
I collected unemployment compensation, updated my resume and applied for jobs with no success. (My field was among the hardest hit of the Great Recession, especially for us older guys.) I also read up on FIRE, increased my presence on this site and improved my understanding of where DW and I stood financially. All the reading I did and the tools I used said we were in good shape. FireCalc indicated 100+%. So, I decided to change "fired" to "FIRED" and tossed the towel into the ring. Done. Finished. Haven't earned a cent since.
I likely would have worked until 62 if I hadn't been fired. I just wasn't tuned into the fact that we had plenty for me to join DW in retirement.
So, not a direct answer to your question, but my situation was different than yours is.
It seems like many folks on this forum are very, very conservative in making the FIRE decision including:
Using s 100% success rate.
Assuming they will live a long, long time.
Adding lots and lots of padding to their projected spend.
Understating their assets and holding much as "standby reserves."
Not including SS or at least discounting it.
Etc.
You may find that the 90% - 95% - 100% portfolio survival rate decision is less important than some of these other factors and, of course, how much you and DH want to get off the treadmill.
Good luck!
