Gross 6500
- say 12% Swiss tax rounded up to 800
- 1500-2000 for housing (Internet, phones, electricity, gas, management etc)
- 500 for food both in and out of the airplane
- 500 for travel related expenses, bus, taxi and what was called Midicar
Leaves you with 2700 to 3200 a month to cover costs at home should you have a home and family elsewhere.
- Costs at home
Left at the end of the month: 500.
This I think makes the comparison easier.
