What Is Subscriber Acquisition Cost (SAC)?

Subscriber Acquisition Cost is the average expense a company incurs to acquire a new subscriber. It's a key metric in subscription-based models like SaaS, streaming, digital newsletters, and gated communities.

The standard formula is:

SAC = Total Marketing Spend / Number of New Subscribers

Why SAC Matters

• It helps you assess your marketing performance

• It’s essential for CAC-to-LTV modeling

• It guides channel investment decisions

• It defines the ceiling for sustainable customer acquisition

How SAC Gets Out of Control

• Platform bans disrupt campaign continuity

• Poor ad targeting reduces conversion efficiency

• Broad targeting leads to junk traffic

• Review bots inflate clicks and kill funnel performance

How Cloaking Helps Optimize SAC

Ad cloaking, when done ethically, protects your ad infrastructure and increases campaign stability:

• Avoids unnecessary account shutdowns

• Filters bots and reviewers from ad funnels

• Improves ad approval and uptime ratios

• Supports GEO-specific or behavioral targeting with split delivery
