I have a relative who is considering moving/Staying in Madrid Spain after the completion of medical studies. 
I had a talk to her about the costs of the EU and the option of coming here to practice. 
Can any of out EU members here show me a resource that illustrates the total cost of life in the EU. Specifically Madrid Spain.

I looked at income taxes but that may not be an accurate measure of all the taxes o e would be burdened with. 

Thanks

Spain, for Northern Europeans, I’m from Belgium, is not expensive.

It should be cheaper than the US.

Keep in mind that Madrid and Barcelona will be more costly than the average.
