After tax, rent, utilities, transport - expect around 6 - 8k sing$ - less if you have kids in private schools - now subtract what else you spend as lifestyle, food (can be cheap or expensive - just depends), etc. Don't always count on 70 hrs /mo either - there are vacation days that will be assigned to your roster if you don't bid them and you don't receive flt pay for those - some months will be alot less than 70 hrs, some will be a bit more. Take heed of the advice given earlier - Sing is getting very expensive - you are buying into a lifestyle here as much as anything and it takes alot of money to fund that lifestyle. The bonus is keeping everyone's head well above water for now - let's keep our fingers crossed that it doesn't go down in a big way
