Cost of being single in Copenhagen is rising to the point that mainstream consumer economists now argue that the best financial “advice” for many residents is simply to share a household — with a partner, a friend, or anyone who can split the fixed costs.
The warning comes as new figures show that single-adult households have become the majority in Copenhagen Municipality, while apartment prices remain at record levels and everyday expenses keep climbing.
Singles are now half of Copenhagen households
Danmarks Statistik data for 2025 put the number of single-adult households (with or without children) in Copenhagen Municipality at 167,399, equal to 50.7% of all households. The share has increased steadily since 2016.
For consumer economist Ida Marie Moesby (Nordea), the trend exposes a central dilemma: living alone is a choice many people value, but it is financially exposed in a city where housing costs dominate monthly budgets.
Copenhagen apartment prices keep rewarding two incomes
Copenhagen’s owner-occupied apartment market has continued to move upwards. According to Boligsiden’s market index, the average price in Copenhagen Municipality reached 66,226 Danish kroner (DKK) per square metre in October 2025 (about €8,900, using Denmark’s long-standing euro peg).
At that level, a 50-square-metre apartment costs around 3.3 million DKK (about €442,000) on average. TV 2 Kosmopol reported that prices were rising by close to 1,000 DKK per square metre per month (about €134) during the period described, with the average in October 2024 at 54,976 DKK per square metre — a yearly increase of more than 11,000 DKK per square metre, equivalent to roughly 550,000 DKK (about €73,700) for a 50-square-metre flat.
Moesby’s point is straightforward: housing-related costs are partly fixed, and splitting them across two incomes can change what is affordable — especially when it comes to buying a home in the capital.
Why sharing a home saves money for single residents
Moesby said previous calculations suggest that living alone can be about 20% more expensive than living with a partner, an estimate she considers plausible.
The advantage is not only rent or a mortgage. In Copenhagen, a large share of essential expenses are easier to absorb when shared, including electricity, heating, water, internet and streaming subscriptions, furniture, and household equipment.
For many residents, this is also why informal solutions — such as moving in with friends or relatives — have become part of the city’s coping strategies as the housing market tightens.
What a monthly budget looks like in the Capital Region
Using Danmarks Statistik consumption data, Moesby compiled a typical monthly budget for an average resident in the Capital Region (Region Hovedstaden), illustrating why singles feel squeezed.
The biggest items are:
- Housing, electricity, water and heating: 11,329 DKK (about €1,520)
- Transport: 5,157 DKK (about €690)
- Food and non-alcoholic drinks: 3,717 DKK (about €500)
In total, the budget reaches 34,635 DKK per month (about €4,640), with additional spending on restaurants and hotels, leisure and culture, household goods, insurance, communications, personal care, and health.
Moesby argued that the most expensive categories are also those where economies of scale matter most, including home-related costs and, in many cases, car ownership.
Inflation has eased, but everyday prices are still rising
Denmark’s inflation surge peaked in autumn 2022, when prices were around 10% higher than a year earlier. After easing in 2023, the annual rate has hovered around 2%.
Danmarks Statistik’s consumer price index showed that in October 2025, prices were 2.1% higher than in October 2024, adding pressure to household budgets at a time when housing costs are already elevated.
The “COLA” phenomenon and the social side of living alone
The growing number of people living alone does not necessarily mean they want to cut costs. Moesby pointed to the so-called COLA phenomenon (couples living apart), suggesting that higher prosperity and changing social norms may make solo living more common — even among people in relationships.
She also framed the trend as part of a longer change in Danish society: more financial independence can reflect higher levels of gender equality, making it easier for women and men to live alone if they choose.
What could change next
With single households rising and housing prices staying high, Copenhagen’s affordability debate is likely to intensify in 2026. If apartment prices continue to outpace incomes, more residents may be pushed toward shared living arrangements, suburban moves, or new housing models.
The Copenhagen case also echoes pressures seen across other Nordic capitals, where high-quality public services coexist with housing markets that increasingly reward dual incomes — and make solo life more expensive than many people expect.
