Got an offer and planning to move

I got an offer from a MNC to join them in Spain. They are offering base salary of 60,000 euros. One quarter of this will go into taxes as they charge 24% flat in taxes from NRI. We are family of 3 and sometimes my parents will also be visiting. With my calculation I don’t think can survive in 3800 euros every month. I need advice on how you guys manage expensive who moved with family? What you expenses looks like? Should i move to Spain?
