When I look at the numbers I recall that they are almost the same as 2005. Unfortunately everything is 30 % more expensive in Singapore now...
Numbers for a family with two children:
Expect to pay around 10000 SGD per month for apartment, maid, car, school fees on top of allowance, utilities and standard household costs. If you are one of those not allowing yourself or your family any joy in life you might do with 7000 but don't be surprised if your wife goes home.
Your total salary will be 18-19000 per month. Taxes around 10 % for a new comer to Singapore.
Setting up as non rated you will need to bring around 80-90000 SGD to cover your costs before you start making any money (training bond, deposits for rent, schools paid in advance etc).
Singapore is a great place to live and SQ Cargo a good company to work for.
