Growth-stage companies average about $2,250 CAC as they move from product-led to sales-assisted models. B2B SaaS CAC often ranges from $200 to $700 for smaller deals, while enterprise-focused products reach the upper end because of longer sales cycles and more complex buyer journeys.

LinkedIn advertising usually generates $120 to $200 cost per lead, which translates to $2,000 to $4,000 CAC depending on conversion rates. HR Tech and staffing verticals often achieve lower CAC around $410 because precise targeting keeps wasted spend low.

Common CAC Mistakes and 2026 Efficiency Trends

Many teams make the mistake of chasing vanity metrics like impressions and clicks instead of revenue outcomes. Percentage-of-spend agency models create conflicts of interest because agencies benefit when you spend more, even if efficiency drops. Systematic CAC work can cut acquisition costs by 40 to 60 percent without slowing growth when you apply accurate channel attribution and strict negative keyword hygiene.

Key 2026 trends include AI-powered attribution modeling that tracks dark funnel interactions and LinkedIn’s continued dominance for B2B targeting. Companies that hit G Squared benchmarks lean into transparency, revenue-based metrics, and deep vertical expertise instead of broad, generalist strategies.
