The cost of living in Ireland varies significantly by location, with Dublin being the most expensive. A single person can expect to pay around €1,200–€1,800 per month, depending on their lifestyle and accommodation. Basic costs include rent, utilities (averaging €120 monthly, but varying by building and climate), groceries (such as bread, milk, and eggs), and transportation. For those seeking to live comfortably, a salary of €50,000 to €70,000 is often recommended, though this can change based on location and family size.

International students in Ireland can work part-time (up to 20 hours per week) during term time and full-time (up to 40 hours per week) during designated holidays, provided they have a Stamp 2 immigration permission. A PPS number is required for employment, and graduates with a Stamp 1G permit can work full-time. EU/EEA students have the same unrestricted access to the job market as domestic students.
