LTV:CAC (Customer Lifetime Value to Customer Acquisition Cost ratio) and CAC payback period are the two primary measures of capital efficiency in SaaS. The "3:1 rule of thumb" suggests a company should generate at least three dollars in lifetime value for every dollar spent on acquisition, but the ratio alone is incomplete without context on gross margins and payback timing. A ratio below 3:1 warrants careful scrutiny of unit economics, while a ratio above 5:1 may indicate under-investment in growth.

Key insight: CAC payback periods have increased significantly across the industry since 2021–2022, when 12–15 month payback was common. The shift toward efficiency and profitability has raised the bar for acceptable CAC, but self-serve PLG models continue to outperform sales-led models on capital efficiency by a wide margin.
