Phil says 10-15% of their Content and Services revenue comes from subscriptions. If we take 15% of the ~$5.41B C&S revenue that means $811.5M sub revenue for the quarter, or $270.5M per month. Divide that by the 34M customers paying, that would mean an average of $7.95 per month per subscriber.
That kind of seems low to me given the base price of $10, or $11, or $17. Of course, there are $60 for 12 month Core subs that will bring the average down. But he says these are paid up subs not promotionary ones, so not $1 subs. But still, Ultimate conversion users are approximately $8/mo, too, so that can explain some of that.
