Customer Lifetime Value Explained
Customer lifetime value estimates what a customer is worth over the relationship. Gross-profit LTV is usually more useful than revenue-only LTV.

The quick answer
Customer lifetime value, often shortened to LTV or CLV, estimates the total value a customer produces over the relationship. For decision-making, gross-profit LTV is usually better than revenue-only LTV because it accounts for cost of delivery.
Formula
revenue_ltv = average_purchase_value * purchase_frequency * customer_lifespan
gross_profit_ltv = revenue_ltv * gross_marginThe Customer Lifetime Value Calculator supports both direct lifespan and churn-based lifespan assumptions.
Example
A customer spends 100 per purchase, buys 6 times per year, stays for 3 years, and has a 70% gross margin. Revenue LTV is 1,800 and gross-profit LTV is 1,260.
LTV and CAC together
LTV becomes most useful when compared with customer acquisition cost. The CAC Calculator shows how much it costs to win customers.
Common mistakes
Do not use revenue LTV when gross margin varies widely. Do not average together very different customer segments. Do not ignore payback period; a strong LTV-to-CAC ratio can still strain cash if payback is slow.
Actionable recommendations
Calculate LTV by customer segment, use gross margin, review cohorts over time, and pair LTV with conversion rate, CAC, and retention. Use the Conversion Rate Calculator to understand funnel movement before acquisition spend scales.
FAQ
Is LTV the same as revenue?
No. Revenue is a sales amount. LTV estimates value across the customer relationship, ideally after gross margin is considered.
What is LTV-to-CAC ratio?
It compares customer value with acquisition cost. It is useful, but it should be read with payback period and cash constraints.
