Spotify’s monthly worldwide ARPU has declined dramatically over the past three years, most recently falling to €4.73 ($5.50) in Q3 2018. That was down over €2 per month, or €24 per year, on the equivalent figure at the close of 2015 (€6.84). One way to push ARPU back up, suggest some, would be for Spotify to increase the price of its offering to consumers.
