Salary negotiations before moving germany

It all depends on what you're going to do. Will you be janitor or CEO?
Taxes and other deductions depend on your personal circumstances so that's also difficult to say.

Hi , I am a software Test engineer with 5+ years of experience in automotive , embedded domain

This site would be a good starting point for your research: http://www.gehalt.de/einkommen/suche/software-ingenieur

@chiku

The base template of costs and the main ones in my opinion would be ;

> Accommodation (furnished or unfurnished)
> Commuting to and from work,
> Food expenses
> A vehicle (if needed)
> Tax of the country you live in

Then the other costs can be related to your life style..

> Entertainment (socializing, going out + eating out)
> Holiday

This is just a general outline.

Benefits, i'd push for is paid flight cost home (annually) & Medical cover.

Hope this helps.
