Luxembourg can be expensive, especially for housing. The scholarship's accommodation support can therefore be very valuable, but it does not remove every cost. Students should calculate rent after any support, tuition fees, food, public transport or mobility costs, insurance, residence documents, books, laptop, phone, and emergency funds.
Cash-flow timing matters. If the scholarship is paid by semester, students may need money before the first payment for travel, deposits, first groceries, local registration, and setup. A student should not arrive with only the assumption that the award will solve the first week.
If you are comparing Luxembourg with Germany, France, Belgium, or the Netherlands, compare total annual cost rather than scholarship headline. Luxembourg's location and labour market can be attractive, but the budget must be realistic from the start.
