A healthy CAC depends on your LTV. Aim for an LTV:CAC ratio of 3:1 or higher. If your CAC is too high, focus on organic channels, improve sales efficiency, or reduce marketing spend on low-performing channels.

How often should I calculate CAC?

Monthly is standard for SaaS businesses. Tracking trends over time matters more than any single data point. Compare CAC month-over-month and year-over-year.

What costs should I include in CAC?

Include all sales team salaries and commissions, marketing salaries, advertising spend, content creation costs, sales tools and software, and any overhead allocated to acquisition. Exclude product development and support costs. Tools like [Baremetrics](https://baremetrics.com?via=saastainednumbers) can help track acquisition costs.

Should I calculate CAC by channel?

Yes. Channel-level CAC reveals which acquisition channels are most efficient. Compare paid channels (ads, sponsorships) vs organic (SEO, referrals, content marketing) to optimize budget allocation. Use [ProfitWell](https://www.profitwell.com) to track channel-level unit economics.

What is the difference between CAC and blended CAC?

Blended CAC averages acquisition costs across all channels. Channel-specific CAC isolates costs for individual channels. Track both for a complete picture.

How does CAC change over time?

CAC typically increases as you scale due to market saturation and channel competition. Early adopters acquired through organic channels are cheapest; later growth often requires paid acquisition.

What is a good CAC payback period?

A payback period under 12 months is ideal for SaaS. Under 18 months is acceptable. Above 24 months signals potential unit economics issues.

How does product-led growth affect CAC?

PLG companies often have lower CAC because users self-serve. Self-serve CAC can be 2-10x lower than sales-assisted CAC, though conversion rates may differ.
