The number in the “QTY” column refers to number of streams or downloads per that song or album. The number in the “Unit” refers to your takeaway per quantity. “Payable” is the amount owned to you (after the partner and CD Baby cuts). You can multiply the QTY by the Unit = Payable.
For example, if you see 3 under the QTY, that means that particular song or album was downloaded or streamed 3 times during that sales period. The amount under “unit” is the amount payable to you per download or stream, let’s say it’s $0.63700000. That’s the amount per download or stream. Now if we multiply that by 3 (3 downloads times the unit price of $0.63700000) = $1.911 and that’s your take home per that line.
Beginning in September, 2020 you will see more detailed Spotify earnings with a greater number of different "unit" (amount payable) amounts. Because Spotify has numerous plans listeners can enroll in, you may see more than one unit for the same song.
