Compared with other western European locations, the cost of living in the Netherlands is relatively low. From my own experience and from my friends’, you will need between €800 and €1,000 per month. To fund this, you can combine part-time jobs and study finance. If you are a EU student, you can work 32 hours a month and be eligible for a €265 grant and a student OV-Chipkaart for free public transportation either during the week or weekends.
There are many useful websites for students to find student accommodation. I would advise you to start looking for accommodation early, because there is a huge demand. From my experience, if starting studies in September, the best months to start looking for accommodation are May, June and July. Definitely don’t wait until August, as you will end up either finding expensive or low quality rooms.
As a student, you can also get discounts in many bars, restaurants, museums and cinemas. You can get around town easily on a bicycle. This is not only typically Dutch, but also a cheap means of transportation. You should definitely ask for an ISIC Student Card to get many more benefits and discounts.
