You need to define " new in his job "

What do you mean a pvt banker new in his job? I.e a private banker who just begin to manage his own portfolio?

Private banker is a very generic term. Just like investment banker.

A private bank has back, middle, front office positions. I am assuming that by private banker you mean the front office RM (note within the private bank, there are product specialists (e.g. fixed income, equity, FX etc), Relationship Managers, Portfolio consultants and even a mini Investment banking team that does P/E & M/A functions for these HNW individuals)

So to really provide good/accurate information, need to drill down and define - else the info/data will be misleading.

If you are narrowing down the term private banker to refer only to the RM type role. This is a role you don't start off in (as I had pointed out). You join the Private bank as some sort of support role in the front office, or as trainee role. Starting pay is 3k-4k.

How much do you get when you become senior enough to start covering clients? This is harder to answer because it depends on the size of your portfolio, profitability and also your years of experience. A VP typically earns 15-20k. Usually, when you start being incharge of a portfolio, you are a VP by then. Bonus entirely depends on your performance.
