Unfortenately it's hard to answer your question without first asking "how you live". There is such a wide range of people in Qatar, earning anything from next-to-nothing to more than you could ever spend. To some QR10,000 would seem like a fortune, to others it would be loose change.

So unless we know what standard of living you're used to it's impossible to answer your question. How much do you currently spend a month? How much are you planning to save? How often will you travel out of Qatar?
