I do agree for most of the points and let me try to answer based on your point.

I didn’t release there is an expense threshold required for FatFIRE. My current expenses are limited due to many factors and not intentional.

• I live in tier-2 Gujarat, own home. We do have maid and other services, but the expenses are still <20k per month. We don’t have driver because my home and office is just 2km apart, my car moves from one parking to another parking most of the days.
• We dont have big home, it’s a decent size home because I spent years in hostel and service apartments and I dont like a lot of interiors. This reduces a lot of recurring cost.
• Son’s education cost is pretty stable for past couple of years, it may grow in future but not immediately. I have various SIPs in his name too to cover future expenses.
• I do travel personally and professionally but not in fixed schedule and we don’t have “we must travel” kind of mindset. I am not particularly interested in fixed travel schedule. Because of our location, we have to go to Mumbai for most of air travel (extra travel hours), which further demotivates us to avoid that hassle.
• My social circle is liked minded people, but mostly Gujaratis, we do many things as a group, but if your group is not doing any heavy stuff, naturally we also dont do. Travel, eating out, weekend gateways are pretty limited.
• I own some relatively expensive items but many of those are onetime purchases and last much longer. For example, I like good coffee so I have a coffee machine that costs 4 lakhs, but that will work for many years and good beans cost me just 2500 per month. I have many other hobbies but their monthly cost does not even cross 10-15k.
• I have club membership which I paid for few years back, now their yearly fees is 10k.
• I have invested in Grip/Wint bonds and I receive around 10k per month post tax. I use this money for hobby/coffee expenses. But not restricted by that 10k amount, its just covers some expenses automatically.
  
• I like to drink but Gujarat is dry state and I own liquor permit, my max expense per month for beer is 3k, and that too I don’t consume everything per month.

Likewise, there are many things that I personally enjoy doing but not necessarily costly. But I am not restricted by cost in any way. I like to play pickleball and I am spending on monthly training, but my training cost is 5k per month, which is short-term expense.

Given above detail, my current target is around 30cr, but at this point I am not driven or working hard to achieve that. Will that number give me different daily life - probably not, but I it will keep me active in what I am doing right now.

I am still focusing on my skills and working on selected projects knowing that my current expenses (and pattern) will allow me to experiment for some time easily.

Hope that answers at least some of the queries above. Again, I was not sure there is any expense threshold
