ELI5: How does Netflix determine how much value it gets from its original programming if there are no ads?

How do they know how these shows affect their bottom line?

Well they can tell how many people are watching them, and because it's a paid service, eyeballs are directly equated to money.  

But a lot of the income is from product placement.  So advertising is still being paid, you're just not seeing commercials.

Consider the totally organic, not obvious Playstation Vita conversation in the first season of House of Cards, or the headphones that provide such perfect noise cancellation that they save the day in Jessica Jones.
