yo, rell everything in the music business is broken down in pennies not dollar amount.
in a "all in" deal, you combine artist and producer % together.
your artist @ 12% and the producer(s) @ 3%. and let's say you have 5 different producers on the album all of the %'s will be added and broken down to pennies. the artist would get 12 cent and all the producers will get 3 cent apiece, per number of tracks that they produce.
example:
producer #1 produce 2 tracks = .06
producer #2 produce 3 tracks = .09
producer #3 produce 4 tracks = .12
producer #4 produce 1 tracks = .03
so if the album sells 100,000 units
producer #1 get's $6,000.00
producer #2 get's $9,000.00
producer #3 get's $12,000.00
producer #4 get's $3,000.00
this doesn't reflex advance money or recording cost.
