Living Expenses in Zealand
All though you will have a relative high salary in Denmark, some of the money you earn will be paid back to the state through tax and fees. Roskilde and the province in the region is not an expensive city compared to Copenhagen. Actually the price level of housing and consumer prices are 20% lower.
The housing market in the region is in general not in high demand, which makes your rent lower and possible investment cheaper compared to housing costs in Copenhagen
.There are local differences between the different cities, so you need to visit the provincial cities to get a feeling whether you like it or not, and assess how much you are willing to pay to fx. live in Køge, Roskilde or Ringsted. According to expatistan.com a 3 rooms flat of 85m2 in a normal area costs in average 950 Euro pr. month in Roskilde.
Restaurants and cafés
You will not find many expensive restaurants on Michelin star level, instead you will find many value for money places with acceptable food, within the price level of 17-20 Euro pr. dish without wine or other beverages. Besides this there are many high quality coffee places with a typical café latte price around 4 euro.
The train system is in general a bit pricy all over Denmark
and the same counts for the Zeeland region. You will probably spend more money on public transport living in Zealand
compared to your transport costs in Copenhagen
, especially if you are commuting to a job in Copenhagen or just visiting Copenhagen often. A fare from Næstved to Copenhagen (1 hour transport costs around 11 Euro on discount card or 17 euro on standard ticket). If you are traveling in short distance, you could benefit by buying a bike and bike instead. The cities are not that big and there are many bike lanes all over - and biking is also sustainable.
