This beats the €22m spent in 2013 when Malmö last hosted the event, as 51,430 unique visitors from more than 80 countries came to the city.
Eurovision also attracted 163 million television viewers.
“With Eurovision, we have advanced Malmö’s position even further in the right direction,” said chair of tourism board Destinationssamverkan Malmö AB Karin Martesson.
“Despite a challenging global situation, we succeeded in planning and executing the event to the benefit of the event itself, visitors, and Malmö residents.
“We have further developed our collaborative model between the city and the hospitality industry into something very effective, which now serves as a solid foundation for future large-scale events.”
The City of Malmö states that Eurovision visitors stayed longer than the average tourist, used commercial accommodation, and spent generously.
It claims that visitors highly rated accessibility and travel options to and within the city, as well as safety and security around the event.
The staging of Eurovision was helped by 550 volunteers and it is hoped that it will lead to hosting of further events in the future.
“When we began planning Eurovision, we encountered great enthusiasm within the city’s cultural and business sectors,” said Malmö’s director of leisure Johan Hermansson.
“Through collaboration with Malmö residents, businesses, and cultural practitioners, Malmö continues to create conditions for future major events and sustainable growth for the city.”
