The short answer, it varies.
The rates streaming services pay aren't up to us -- and we have no control over changing them. We just send along the exact amounts that stores send to us. DistroKid passes on 100% of whatever earnings the stores send us for your sales/streams, minus banking fees/applicable taxes. 💯
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.
Spotify has a great video that explains how earnings are calculated on their end: How Spotify Pays You
