Key Takeaways
- CPA must be evaluated against Customer Lifetime Value: CPA < CLV/3 is the healthy benchmark.
- Target CPA bidding in Google Ads automates bid optimization but needs 30+ conversions/month for reliable machine learning.
- CPA varies by conversion type: a lead form submission has lower CPA than a completed purchase because it is earlier in the funnel.
CPA Benchmarks by Industry
| Industry | Avg CPA (Search) | Avg CPA (Display) |
|---|---|---|
| E-commerce | $45-65 | $65-80 |
| SaaS / Technology | $80-150 | $100-200 |
| Legal | $85-135 | $50-75 |
| Real Estate | $75-120 | $55-80 |
| Education | $70-100 | $100-150 |
These are average CPAs for Google Ads. Your target CPA should be calculated from your specific CLV and margin, not from industry averages. A SaaS company with $50,000 CLV can afford $500+ CPA that would be unsustainable for an e-commerce store with $200 CLV.
