From California to Netherlands?

I got an offer from one of the Dutch companies in Amsterdam for software engineer position. The base salary (gross, excluding 13th-month package) is EUR Protected content one time sign on bonus. We are eligible for 30% ruling.

We have two young kids. We expect to send one to a childcare and another one stays with my wife at home.

From my research, we are not eligible for childcare benefit, since my spouse is not going to work. We expect to have the following expenses:
~ Protected content rent,
~ Protected content daycare,
~ Protected content ,
~700 towards food and other necessities

If I calculated correctly, our monthly paycheck should be ~6500
Protected content

So we should have $ Protected content for other things. We also plan to do 1 or 2 train trips a month to other cities or neighboring countries.

Does my math make sense?

I really appreciate your input
