I think the guy who started this whole thing is looking to maximize his appeal by not being too prescriptive. That said, most adherents would say living on 70-100K is exploding-volcano-of-waste territory regardless of how much money you make. I would say it's hard to design a mindful and intentional lifestyle that consistently consumes that level of resources, though theoretically possible. Depends on what the expenses are for.
Oh, sorry about that! My situation is that I make $120k per year but since finding MMM am trying to get my yearly expenditures down to $25k or so.
Sorry for what?
FWIW, my situation is very similar. Total (FT+PT+rents) is about $120k, used to spend more or less the entirety, cut spending below $3k/mo with a goal of <$2K.
There are various reasons for doing that... in my case, I don't think it's wrong to spend more, but I have to get there temporarily to ensure I can quit FT work and be able to pay my bills with only my existing PT jobs. Once I have that free time I expect income to rise again but my highly risk-averse nature demands baseline costs below baseline income
before I make the leap, regardless of savings. I've been broke more than once, and I don't ever want to go backwards again.
I don't see a reason to harp on the 25k number (which, btw, isn't really 25k. It's 25k + opportunity cost of having a paid for house + your property taxes if you live in an area where your property taxes are more than MMMs 1200/yr or whatever they are).
Yeah, I've seen people do the math on that and it worked out to more like a $40K equivalent via the paid-for house, etc.
edit:But it's still a good baseline figure if you plan on using the same strategy. It does represent actual spending, after all.
