Inspirato

In an SEC-filed 2021 investor presentation, Inspirato defined CAC as total acquisition spend divided by customers acquired in a given period. It reported estimated LTV-to-CAC and payback metrics alongside assumptions about subscription types and retention. These are company-defined measures, not a standard accounting ratio.

Inspirato’s SEC-filed presentation defines LTV using expected subscription and usage-based revenue over the expected subscriber period, adjusted for an assumed margin and possible upgrades. That definition is useful for reading its estimates, but the model remains sensitive to future retention and mix.
