CLV / LTV Calculator

Customer lifetime value tells you what a customer is really worth — and therefore what you can afford to spend acquiring one and still come out ahead.

How this is calculated

Revenue LTV = average order value × purchases per year × customer lifespan in years. Profit LTV applies your gross margin to that figure, since revenue isn’t what you actually keep.

Profit LTV is the more useful number for acquisition decisions: it’s roughly the ceiling on what you can spend to acquire a customer (via ads, discounts, or otherwise) and still be profitable over their lifetime — not just on their first order.

FAQ

Should I target break-even ROAS on the first order, or on lifetime value?

Many profitable Shopify stores accept a loss (or break-even) on a customer's first order because repeat purchases make them profitable over time. If that's your model, size your acquisition spend against profit LTV, not first-order margin alone.

How do I estimate customer lifespan if I'm a newer store?

Use a conservative estimate (1–2 years) until you have enough repeat-purchase history to calculate it from real cohort data. It's better to under-estimate LTV and be pleasantly surprised than over-spend on acquisition.

Does this account for acquisition cost?

No — this calculates what a customer is worth, not what they cost to acquire. Compare the Profit LTV result against your actual CAC (spend ÷ new customers) to see if the relationship is healthy.
