45M / married, 3 kids under 8 $6.6M NW, $5.6M investable.
Based on an $18K per month spend (soon to be $16K), my FA says I can quit tomorrow (87% success).

My question:
Right now, I am thinking about doing one more year. Although I hate my job, I feel like I could wrap my head around a “12 month countdown.”
And it would likely mean another $500K (before taxes, but after all other expenses).
But I worry is the market drops 25% in the next 12 months, and all of a sudden, I’m forced to do X more years until it recovers.
Is my plan prudent? Or am I over-thinking it, and I just need to bite the bullet and then figure it out as it comes?

Thank you all! I really appreciate the wisdom of this group.

Additional details:

1. Very low rate mortgage is almost paid off, once done, will eliminate $2K in monthly expense
2. Kids are almost out of daycare which will eliminate $3K in monthly expense
3. The elimination of daycare will likely be offset by private medical insurance

Additional levers:

1. I don’t ever plan on “not working.” Although at some point, I’d like to do some $0 jobs, I think my “first retirement job” might still be be in corporate tech, but at a much lower level with lower stress.
2. My wife and I both grew up without much, I think we could find a lot of flexibility in our budget if SORR started to emerge.
3. Although we’re not counting it at all, we expect a $1-$3M inheritance from my wife’s parents who are now 76 y/o

I believe I could achieve FIRE immediately if I was offered a severance package.  Has anyone here TRIED to get severed from their company?  Is that something I might be able to influence, or is it just a pipe dream?

My details:

I am in an executive band on a deferred compensation plan, so the severance package in total could be close to $1M.  (I’ve seen at least one peer dismissed with a similar package.)

I am 45, married, 3 kids 2/5/7.  $6.5M NW, 2.5M in 401, 2.5M in brokerage, 1M in primary residence, and .5M in 529s.  Yearly burn right now is 215K.  The two younger kids are in daycare, the older one is in public school, and all three are in summer camps (childcare=$3K/month).  Mortgage principal and interest is 1.8K a month, on a balance of 179K at a very low rate.  However, when I’m no longer paying daycare and mortgage, I will likely need to be paying for health insurance.

I was wondering if anyone else has thought about how severance might affect their FIRE goals and if anyone has intentionally gone after a severance package?

EDITS:

Adding for clarity - I really hate my job and am burnt out. So I am looking for a way out.
