Please help me understand-- I mean this sincerely--- not a sarcastic comment. You currently spend very little and live a frugal life--- something like 14-22k/year. When you retire, you expected to fatFIRE at around 50k or so if you stayed at your current house, but now considering inflation and moving, you expect that to be around 90k. Quite the jump in lifestyle, isn't it? Do you feel like you're currently missing out on life and retirement is your chance to go wild?
I hate to derail the thread but I'll answer your sincere question.
$14,670 actual spent in 2020, including discretionary spending, but excluding taxes.
The $22K figure was estimated FIRE bare bones spending including sinking funds for longer term expenses averaged out, living in my existing home, but excluding discretionary spending.
The $50K + 50% more that I mentioned in the earlier quoted post that my stache could support at that time was $75K/yr.
Since then, delaying FIRE another year, additional growth in my stache, additional contributions to my stache, and including a received inheritance, my total stache will now support $90K/yr. That would include all spending including taxes and large expenses/purchases averaged out over time. This makes it more affordable to relocate but isn't dependent upon it.

While the $14.6K and $22K figures are based on actual 2020 spending and expected bare bones expenses for FIRE in my current home, the $75K and $90K figures are a function of the math of what my stache will provide for spending rather than wanting to go wild, but I certainly expect more discretionary spending needs just with all the extra free time I'll have, especially compared to how restrictive I've been in recent years (although I did splurge and finally bought a $1500 e-bike this year). Relocating would be an additional expense that would offset how much is available for discretionary spending. So either way, $90K/yr spending would be averaged out. After taxes and significant home repairs/improvements that I've put off, and all bare bones expenses, and excluding inheritance from the calculation, that will only leave about $50K/yr for discretionary spending, maybe less depending on relocating. I'm reserving the inheritance for possible house selling and buying at this time. $50K/yr discretionary still feels like fat fire to me since it's close to 20X my current discretionary spending, but I've seen people on this site talk about $30K/yr travel budgets and even $20K on a single trip! So $50K over a whole year doesn't seem too crazy. The inheritance would only boost that about $4K/yr if not spent on housing changes.
So, yes, it's a big jump in discretionary spending from my current working lifestyle because the math will require it to spend down my stache. I don't expect my inherent frugal nature to suddenly change, though, so it might be difficult for me to suddenly spend that much when I FIRE, but I'll have to work my way through that.
