The final took place on 3 March 2018 where the six entries that qualified from the preceding two semi-finals competed. In the semi-finals, all competing entries were required to be performed in Icelandic; however, entries competing in the final were required to be presented in the language they would compete with in the Eurovision Song Contest. Two entries remained in Icelandic ( "Í stormi" performed by Dagur Sigurðsson and "Kúst og fæjó" performed by Heimilistónar), while the other four entries competed in English. In the first round of voting, votes from a jury panel (50%) and public televoting (50%) determined the top two entries: "Our Choice" performed by Ari Ólafsson and "Í stormi" performed by Dagur Sigurðsson. Jury voting involved international jurors alongside Icelandic members. The top two entries advanced to a second round of voting, the superfinal, where the winner, "Our Choice" performed by Ari Ólafsson, was determined solely by televoting. In addition to the performances of the competing artists, the interval acts featured guest performances by 2013 Eurovision Song Contest winner Emmelie de Forest, who won for Denmark with the song "Only Teardrops", and 2017 Swedish Eurovision entrant Robin Bengtsson.
