Students could save around €7,000 a year by staying at home instead of moving out while attending college.
According to the TU Dublin Student Cost of Living Guide, students who move to Dublin need a budget of €13,000.
Shopping around for utilities, making lists for groceries and moving in with a family are all suggested in the guide to save money.
Student Engagement and Experience Officer for TU Dublin, Rachel O'Connor, says digs can provide a homely start to college for those who might struggle living alone.
"Students don't often see it as their first option but actually when they go into digs, they realise how good it is and how satisfied they are with it.
"In purpose built student accommodation, you're probably looking in and around the €250 a week mark but if you were to go with digs, you're looking at €165.
"Often, that's over 5 days and it will include meals and utilities."
