The final took place on 12 March 2016 at the Friends Arena in Stockholm, hosted by Gina Dirawi and William Spetz. Twelve entries competed during the show. Eight of the entries qualified directly from the semi-finals, while four of the competing entries qualified from the Second Chance round. The winner was selected by a combination of viewer votes and eleven international jury groups. The viewers and the juries each had a total of 473 points to award. Each jury group distributed their points as follows: 1, 2, 4, 6, 8, 10 and 12 points. The viewer vote was based on the percentage of votes each song achieved through the following voting methods: telephone, SMS and mobile application. For example, if a song gained 10% of the viewer vote, then that entry would be awarded 10% of 473 points rounded to the nearest integer: 47 points. Viewers were able to cast their vote in the final from the start of the show until five minutes after the jury groups had distributed their points, allowing the viewers to respond to the outcome of the jury results. In the event of a tie, the viewer vote would overrule the jury. "If I Were Sorry" performed by Frans was selected as the winner after placing second with the international jury vote and winning the public vote to finish with an overall 156 point total.
