Cost per acquisition is the metric that separates sustainable businesses from those burning cash. In 2026, with rising ad costs and increasing competition, CPA optimization isn't optional—it's survival.
Understanding CPA in 2026
CPA = Total Ad Spend / Number of Acquisitions
Simple math, complex optimization. Every lever you pull affects the equation.
Industry Benchmarks
| Industry | Average CPA | Good CPA | Excellent CPA |
|---|
| E-commerce | $45-100 | $30-45 | Under $30 |
|---|---|---|---|
| SaaS B2B | $100-200 | $70-100 | Under $70 |
| Lead Gen (B2B) | $50-150 | $35-50 | Under $35 |
| Lead Gen (B2C) | $25-75 | $15-25 | Under $15 |
Your acceptable CPA depends on LTV, margins, and business model. A $200 CPA is great if LTV is $2,000.
