Customer equity, the asset value of customers, can be measured using different aggregate- and disaggregate-level approaches. The authors compare how customer equity is measured and maximized under various approaches. We find that, in the disaggregate-level approach, customer lifetime value is maximized by implementing customer-level strategies such as optimal resource allocation, purchase sequence analysis and balancing acquisition and retention spending. At the aggregate-level, improving the drivers of customer equity maximizes customer equity. A comparison of different aggregate approaches shows that, while an emphasis on retention is a common feature across approaches, conceptual differences in terms of accounting for existing customers and prospects, acquisition, and the projection period exist across the different approaches. The authors propose a hybrid approach, which addresses the issues and challenges in existing approaches and helps firms to measure and manage customer equity.
