    How much detail would you like?

    Practical

    Relevant for acquisition budgets, customer loyalty, service prioritization and business models. The value is a model-dependent estimate, not a safe property of a person.

    A service company estimates the discounted contribution margin of typical customer cohorts and compares it with acquisition and support costs.

    Transparently calculate CLV by customer group and business model, document assumptions, test sensitivity and interpret it together with acquisition costs, retention and capacities.

    At a glance

    Core
    CLV may include expected turnover, contribution margin or net worth, depending on the model. Therefore, the period, margin, retention probability, discounting and included acquisition and support costs must be explicitly documented.

    Example

    A service company estimates the discounted contribution margin of typical customer cohorts and compares it with acquisition and support costs.

    Pitfalls and limits

    • Confuse sales and profit; mix historical and forecast values; issue a simple formula as a universal standard; ignore churn, margin, cost or discount; treat individuals unfairly; invest LTV duplicates.

    Origin & history

    Lifetime value models were disseminated especially with database and direct marketing. Today, numerous historical and prognostic calculation methods exist without a single universal formula.

    Use in mid-sized companies

    • Transparently calculate CLV by customer group and business model, document assumptions, test sensitivity and interpret it together with acquisition costs, retention and capacities.
