What Is the Cost per First Stream Metric? Amazon Prime Video Revenue Model Explained (2025 Update)

The cost per first stream (CPFS) remains a **critical performance metric** used by Amazon to evaluate the effectiveness of its Prime Video content investments. In 2025, this metric has evolved to incorporate not just production and marketing expenses divided by initial viewers, but also factors in advertising revenue and cross-platform engagement metrics. With Amazon’s streaming service now reaching **over 220 million global subscribers**, understanding this metric has become increasingly crucial for content strategy decisions.

### The Evolution of Amazon’s Streaming Economics

In 2025, Amazon Prime Video’s revenue model has transformed significantly from its earlier iterations. The platform now generates revenue through:

– **Premium subscriptions**: Starting at $139/year in the US
– **Advertising revenue**: Contributing **$56.2 billion** annually
– **Pay-per-view content**: Including sports events and new releases
– **Cross-platform merchandising**: Leveraging content for e-commerce sales

### Modern CPFS Calculation Framework

The 2025 CPFS calculation now incorporates several new elements:

“`
CPFS = (Production Costs + Marketing Expenses – Ad Revenue) / First 30-Day Viewers
“`

For example, Amazon’s hit series “The Continental” (2024-2025) had:
– Production budget: $185 million
– Marketing spend: $45 million
– First-month viewers: 28.3 million
– Ad revenue: $22 million

This resulted in a CPFS of approximately $7.35 per viewer, representing a **42% improvement** over 2023’s average CPFS of $12.80.
