CAC vs what a customer returns
Read it like an operator
First orders cover 51% of CAC, and full payback lands at 7.4 months. Everything after that point is compounding return — which is why retention work moves this model harder than one more point of CVR.
The math, shown
| CAC | (ad spend + team & tools) ÷ new customers | Fully loaded — media-only CAC flatters the number and hides real economics. |
| LTV | AOV × orders/yr × gross margin × lifespan | Gross-profit LTV. Revenue LTV overstates what you can actually spend. |
| LTV : CAC | LTV ÷ CAC | Under 1 loses money; 3:1–5:1 is healthy; far above 5:1 often signals underinvestment in growth. |
| Payback | CAC ÷ monthly gross profit per customer | The cash-flow number: how long acquisition capital is tied up before it returns. |
