How it is calculated
Annual gross profit per customer = average order value × margin ÷ 100 × purchases per year. LTV = annual gross profit × years retained — the total profit a customer generates over their whole time with you.
Calculating LTV from revenue instead of gross profit is a common mistake: it inflates the number and makes any ad spend look profitable. Margin is what separates a customer's real value from the turnover they push through you.
LTV only means something next to acquisition cost (CAC): the LTV/CAC ratio is the main health indicator of a customer acquisition model. Below 3, the model usually can't carry the rest of the business's costs at scale; above 5 can be a sign you could spend more aggressively on ads.
