Frequently Asked Questions

How is CAC calculated?

Customer acquisition cost = Total marketing & sales spend ÷ New customers acquired. Include ad spend, salaries, tools, and agency fees in the spend figure.

What is a good CAC?

A healthy CAC depends on LTV. Many SaaS businesses target LTV:CAC of 3:1 or higher — use the Customer Lifetime Value Calculator to compare.

Should I include sales team salaries?

Yes for a fully loaded CAC. Some teams report blended CAC (all channels) vs. paid CAC (ad spend only) — be consistent in what you include.

How does CAC relate to ROAS?

ROAS measures ad efficiency per dollar spent. CAC is cost per customer. Use the Return on Ad Spend Calculator to evaluate campaign performance.

Is this tool free and does it work on mobile?
