I'm moving from one company to another but I don't know how to ask for a better pay raise. How do I ask for a pay raise the right way without overstepping? What traits about me should I highlight?

1) Check for your industry's salary jump range (glassdoor, recruiter salary reports etc)

2) Were you headhunted or did you source for it yourself?

3) Is this a lateral jump (same level, different pay) or an upwards jump (promotion)?

4) like Yudit mentioned, factor annual compensation instead of just looking at monthly salary.

5) For traits, quantify as much as possiible what you have done for your existing company (e.g. bring in X dollars of sales within 6 months, clinched 10 new clients in a year, grew a team from 1 to 5 within 2 years etc).

6) Lastly, what's the worse that could happen even if you ask for a higher range? Of course don't be ridiculous and ask for 50% increase, what I like to do is ask for 30% with the expectation that they would go to 15-20% -- so far it has worked for me!

The only thing you need to stress on is your work output and how much you've contributed as an indispensible part of the company.
