IMHO, you pay depends on your portfolio but not until few months of working, that is if your a fresh grad.

If you are already a senior, which means u have worked in the same design firm/studio for at least a year, you can get more out of your portfolio,

you know just act like you wanna quit, or just talk to your boss, of course you need to do this when you seem to be an asset to the company, it would be easier to do this in a small studio rather than a big firm, they might just fire you.

In malaysia, if you really want to earn, you have to be one of the best,

you have to be that someone studios/firms die for, they want you so much they would even ask you how much you want as your salary.

In a different perspective, don't design for money, design because you love designing, when you have this mindset, you would definitely have a good portfolio.
