The cost of living in Spain is roughly €1,093 per person per month, though this can vary significantly based on location and lifestyle. Monthly expenses for a single person can be as low as €1,200 if they are frugal, while a family might spend around €2,718 per month. Key costs include housing (which is highly location-dependent, especially in cities like Madrid or Barcelona), food, utilities, and transportation.

International students in Spain can work part-time, up to 30 hours per week, if their studies permit it and they have a valid student visa. The employer must apply for work authorization on the student's behalf, and the work must not interfere with their studies. Alternatively, students can work through an official internship agreement called a convenio de prácticas or prácticas.
