5500 QR is OK for a fresh engineering graduate struggling to get a foothold in the industry, but not for a sales rep in bank. I think you will be able to save here only as much as you do in your country, even if it is India. Also beware the laws here heavily favour the sponsors, and once you are here, you cannot dream about a change of job. About saving potential you can expect to save around 3000 QR from that if you are a bachelor.
