LTV: customer lifetime value

LTV estimates how much revenue or margin a customer contributes over the full relationship—and sets the ceiling for CAC and growth ambition.

What it is

Lifetime value can be modeled simply (average order value × purchase frequency × lifespan) or cohort-based with repeats and expansions. Finance and marketing must agree whether the numerator is gross revenue, net revenue, or margin.

Why it matters for business

Without LTV you optimize channels for cheap traffic while the business may never recover acquisition spend. Investors and CFOs anchor unit economics on LTV, not reach KPIs alone.

How to apply it

Build cohorts from first purchase dates. Separate revenue from margin; handle refunds. Tie to churn and retention plays in email and CRM. Align the definition of “customer” with finance.
