Just to give a different perspective, I am budgeting for a not-ascetic but also not-extravagant lifestyle (cook at home, buy nicer clothes less often, buy cars new but stick to low maintenance budget models, etc.), dual-income family, kid(s), one or two trips a year (one to travel, another to visit family), some hobbies with equipment costs, a chronic medical condition I was diagnosed with at 25 that is minimal impact right now but will almost certainly get expensive when I'm retirement age, some ongoing memberships like for state parks, etc.

Factoring in taxes, it adds up to more than I'd like but less than I would intuitively assume.
