The calculator (https://www.deezer.com/us/ucps/me) is blatantly incorrect. 

It states that 1000 streams in a month means that 99% of my subscription goes to artists I didn't listen to. 

Example:

There are 3 million subscribers in September paying $10. 

The total pot is $10 * 3,000,000 = $30,000,000

They each stream 1500 times in a month, for a total of 4.5 billion streams. 

User A streaming 1000 times in the same month, means they have (1000 / 4,500,000,000) of the total streams. 

The payout for those 1000 streams will be (1000 / 4,500,000,000) * $30,000,000 = $6.66

The percentage of their subscription going to their artists ($6.66/$10) * 100 = 66.6%

If User B streamed the average amount of 1500 streams, their generated royalties would be (1500/4,500,000,000) * 30,000,000 = $10

100% of User B's subscription would go to their artists. 

In order for https://www.deezer.com/us/ucps/me to be correct, the average Deezer subscriber would have listened to 100,000 streams in September. At an average of 3 minutes per song, that would require 5000 hours of monthly listening, or 166 hours per day.
