Netflix pays an estimated $100 to get a new subscriber in the US

"Netflix’s cost of adding new subscribers on its home soil in the US has rocketed in recent years, reaching $100 (€86) per net new subscriber, according to Ampere Analysis. Acquisition costs for domestic subscribers have increased significantly in recent years; from 2013-2015 the cost of a net new domestic subscriber stood at a stable figure of around $60.
In contrast, Netflix’s cost of adding international subscribers has remained relatively flat at $40-$45 for each new customer it adds. So, while headlines about content spend dominate, this report focuses on Netflix’s significant investment in marketing."
