Customer Acquisition Cost (CAC)

What it measures

Total cost to acquire a new paying customer, including marketing spend, sales salaries, tools, and overhead allocated to acquisition. Note: no standardized calculation method exists—companies calculate CAC differently, making benchmarking imprecise.

Calculation methods

• Paid CAC: Ad spend / New customers via paid channels. Best for measuring channel efficiency and optimizing specific acquisition campaigns.
• Blended CAC: Total acquisition cost / Total new customers. Best for measuring overall business health and unit economics across all channels.

Benchmarks

• No single "average" exists — CAC varies widely by industry and buyer segment.
• SMB-tier figures (FirstPageSage, 2025): ~$274 (e-commerce) up to ~$1,450 (fintech); enterprise-tier CAC runs several times higher.
• Treat any published figure as order-of-magnitude only — your own blended CAC is the number that matters.

Figures reviewed June 2026. Benchmarks vary by source and drift over time — treat as directional and verify against your own data.

What to watch

• Falling: Acquisition is more efficient, but verify quality. Cheaper customers may churn faster or spend less. Pair with LTV to ensure you're not sacrificing long-term value.
• Rising: Competition is intensifying, or you've saturated easy-to-reach audiences. Segment by channel, as some channels scale poorly. If LTV rises faster than CAC, rising costs can still be profitable.

In practice

A SaaS company saw paid search CAC rise from $120 to $180 over six months as competition increased. Content marketing CAC was $95 but took 6 months to show results. They maintained paid search for immediate pipeline while investing in content for long-term CAC reduction. Blended CAC stabilized at $135.
