So what does the artist make per dollar when I buy a digital album?
* Apple still takes 30 percent of whatever you buy through iTunes, right? But then they cover transaction costs?
What do the other biggies do? Amazon, Google?
The ones I use:
* Bandcamp charges 15 percent (https://bandcamp.com/pricing) reducing to 10 at higher volumes - plus transaction costs (https://bandcamp.com/help/selling#fee). Make that 20 percent for a typical album?
* CDBaby charges 15 percent as well on a free account (https://members.cdbaby.com/retail), but only 9 percent for a paying account. Dunno about transaction costs.
What about Boomkat? Others?
IndieTorrent charges 15 percent, transaction costs included (https://indietorrent.org/docs/).
Found a couple of sources:
and (reliable or not)
http://www.hypebot.com/hypebot/2011/09/how-much-does-a-band-earn-from-each-music-platform-uniform-notion-shares-the-numbers.html and https://www.quora.com/What-is-the-revenue-breakdown-for-an-album-sold-on-iTunes-or-Amazon-mp3
So it seems the three big ones have all landed on 30 percent, but according to the above sources, it costs $35 a year to have an album available on iTunes or Amazon. Google Play has a somewhat more artist-friendly price tag: a one-time $25 for your "brand", that is, your band.
I don't know if it is (still) correct that you cannot sign up with iTunes directly?
No surprise that "the others" offer the artists more, of course.
