Answer
For two adults, a comfortable month without luxury can be estimated at $2,400–$2,700. This estimate excludes lavish spending but assumes an ordinary standard of living rather than strict austerity.
Cafés and leisure should be budgeted separately: going out two or three times a month can add about $150–$200. In the first weeks, expenses are usually higher because of temporary housing, communications, transport, small purchases and setting up daily life.
The budget depends heavily on the area, rent, healthcare, transport and eating habits. Instead of an abstract average, calculate a personal basket: housing, utility bills, groceries, communications, health, transport and a reserve.
