i think having 2- 3k if you live by yourself is preety comfy

That's provided you don't pay rent or have a mortgage.

Well, depends on country and city, in some places 2-3k is def enough to be comfy renting, I'm doing that rn. But I can agree that for big or expensive north american or european cities it's probably not enough to be pretty comfy and it's more like, a bit better than paycheck to paycheck, if anything.

I will vote for the 3-5k a month depending on where you live is okay to comfy
5-7k a month is the good amount and hope that you're saving/investing
7-12k of individual income is quite effing good, and def on the okay side of combined income (with kids)

I survived most of my upbringing with a lot less than that, so, still sounds doable.
