In February 2016, Femern A/S produced an analysis of the economics of the project, including construction costs, operating costs, maintenance and reinvestments, EU subsidies, traffic revenue and interest expenses.  The analysis showed that the economics of the project are sound.

The Fehmarnbelt Fixed Link’s overall financial framework of DKK 55.1 billion (2015 prices) is determined in the 2015 Construction Act. Femern A/S follows a construction budget of DKK 52.6 billion as its management and reporting basis of which DKK 7.3 billion are reserves. The size of reserves has been determined by the professional services organisation, EY, on the basis of a thorough external audit of the economics and risks of the project.
