The monthly baseline
Three independent trackers converge on a similar range. CityCost puts a single person at about US$1,113 a month including housing, or US$627 without it, and a couple at US$1,669 including rent. Wise's average lands at US$1,235 a month, with housing accounting for roughly half of it. A mid-tier remote-work budget comes in near US$905.
The practical reading: below about US$900 you are compromising on location or space; above about US$1,500 you are buying comfort rather than necessity.
