Frequently asked questions

What is Blended CAC vs Paid-only CAC?

Blended CAC uses all sales-and-marketing spend. Paid-only CAC uses paid-media spend. Never say "blended" alone.

When is CAC Payback Period shown?

Only when you enter a monthly ARPU (and Gross Margin). It is absent — not zero — otherwise, so an AOV is never labelled as months.

Do I need an account?

No. On-screen results are free. Enter an email only if you want to download the report.
