"In royalty payments, there’s a writers share and a publisher’s share. To make things easy, let’s say each share is worth 100%. So the writer has a pie chart of 100% and the publisher has a pie chart of 100%. If there are multiple writers on the track, then they will split the shares accordingly, 50/50 or 25/25/25/25 if there were 4 writers. After the writers share is calculated, you can calculate the publisher’s share or vice versa. A record label would usually own 100% of an artist’s publishing rights, but if you enter into a co-publishing deal, then the label would only get 50% of your publishing. To break it all down, if an artist negotiated a 50/50 split for publishing, and retains 100% of the writers share, then the artist would get half of the publisher’s share and 100% of the writers share. This would be equal to 75% of the total royalty payment. If you publish your own music, this means you get to keep 100% of your royalties..."
