What's there to flaunt about $260K per annum? After tax, that's a scrape-by salary for expats. Even more so if one has children and wants to educate them privately. There won't be much left over for holidays back home (or much else) either. Why bother coming, unless you really don't have any other options.
1) Have you ever heard of a thing called Google? Using it you can find cost of living information for Singapore, you can find school tuitions, cost of a car, club memberships etc.
2) The OP did not have a specific question, he just asked "Is it enough?" What the hell is that supposed to mean? I wonder what kind of profession he is in, because he doesn't seem too skilled in information gathering.
3) Just looking at the cold hard statistics, 260K is NOT a scrape by salary for expats. I find it laughable you make such bombastic statements without any hard data to back up your wild assertions.
4) How is there not enough left for "holidays back home"? Maybe look at some travel websites and you will quickly see there is more than enough for a holiday.
I really wonder why you posted such nonsense. I can only conclude you don't really believe what you say, you are either repeating what you overheard or are just trying to wind people up.
