A practical guide to customer lifetime value

October 6, 2026 · fcadmin

Customer lifetime value (LTV) is the total profit you expect from a customer over their relationship with your store.

How to calculate it

A simple version is average order value × average number of orders per customer × gross margin. Cohort-based LTV is more accurate: track how much each group of customers spends in the months after their first order.

Use LTV to set acquisition budgets

If a customer is worth $200 in profit over a year, spending $60 to acquire them can be a great deal, even if the first order loses money. Compare LTV with acquisition cost by channel to see where to invest.

Increase LTV

  • Follow up first orders with helpful post-purchase emails.
  • Recommend the products that lead to repeat purchases.
  • Offer subscriptions or replenishment reminders for consumables.

FCAnalytics calculates lifetime value by channel, first product and segment, and shows the payback period for every acquisition source.
