TikTok earnings are based off of the number of videos that use the artists music, not the number of streams those videos have. You may need to Google around and/or check their FAQs for current rates. Keep in mind that rates may change or fluctuate over time, depending on the total number of streams by all artists, the territory of the streams, and a bunch of other factors.
As always, DistroKid passes on 100% of whatever earnings the streaming services send us for your streams/sales, minus banking fees/applicable taxes. Unfortunately, the rates they pay aren't up to us -- and we have no control over changing them. We just send along the exact amounts that streaming services send to us.
