Why contribution margin LTV

Gross LTV makes everyone feel better but only contribution-margin LTV is the dollar amount you can spend acquiring a customer and still be profitable. If you've ever seen an agency quote "LTV:CAC of 5×" against gross — that's the move. We never report it that way.

At 55% margin and a 2.5-year horizon, your usable LTV for paid acquisition decisions is $440.
