Luxembourg is one of the costliest countries in Europe. A single person needs around €2,200 to €2,800 per month to live comfortably. Rent is the highest expense, especially in the city center, where a one-bedroom apartment can cost €1,800 to €2,400. Utilities, internet, and mobile bills may add another €200 to €350. Groceries and daily expenses can range from €300 to €550 every month. Eating out and entertainment are also expensive. Public transport is free across the country, which helps reduce some daily costs.
