Most people who start with Airbnb in Copenhagen think about income as a question of filling the calendar. That is the wrong way to think here. The 70 night limit means you cannot grow by renting more. You can only grow by selling the nights you have at a better price. Two neighbours with identical flats can end the year 50,000 kr apart on exactly the same number of nights.
In Copenhagen you may rent out your primary home for up to 70 nights a year when you use a platform like Airbnb that reports to the Danish Tax Agency. The municipality raised the limit from the default 30 nights. The cap is hard: once the 70 nights are used, the year is over, no matter how many guests still want to stay with you.
So think of your 70 nights as stock you get to restock only once a year. Every time you sell a night cheaply, one is gone. A night in February and a night in August cost you exactly the same, one out of 70, but they are not worth the same.
Copenhagen is a highly seasonal market. August is clearly the strongest month, with June and July close behind, while January, February and March are the bottom. In market data for 2026, occupancy in August runs at around 64 percent, while in February it can fall below 30 percent. An average Copenhagen listing sits at roughly 1,500 to 1,600 kr per night across the year, but in an ordinary February week you are fighting for guests at maybe 900 to 1,100 kr, while the same flat in a good August week comfortably reaches 2,000 kr and above.
