How this calculates

LTV = average order value × purchases per year × customer lifespan in years. Revenue LTV is the top-line number. Contribution LTV applies your gross margin so you know how much real profit each customer produces. Use contribution LTV when comparing against CAC, because CAC is an after-margin cost you recover from after-margin revenue.
