The Loyalty Effect
Retention economics: why loyal customers and employees drive returns
Summary
Reichheld, a Bain consultant, argues that customer, employee and investor retention are the primary drivers of profitability and growth, and that most businesses measure and manage none of the three properly.
The economic argument is worked out for customers. A retained customer becomes more profitable over time through a sequence of effects: the acquisition cost is amortised over more years, base profit accumulates, purchase volume grows, operating costs fall as the customer learns to use the service, referrals generate new customers at no acquisition cost, and price premium becomes available as the relationship deepens. Reichheld presents the arithmetic showing that a five percentage point improvement in retention rate can raise customer lifetime value by a large multiple depending on the industry.
He extends the argument to employees, showing that turnover destroys the relationship knowledge that customer retention depends on, and to investors, arguing that fast-turnover shareholders push management toward decisions that damage the other two forms of loyalty. His cases include State Farm, USAA, Lexus, MBNA and Leo Burnett.
The book has had enormous influence and Reichheld later developed the Net Promoter Score from this work. The main criticism is causal direction: profitable customers are also more likely to stay, so retention and profitability are correlated without retention necessarily causing profitability. Later research has found the loyalty-profitability relationship weaker and more industry-specific than Reichheld claims, and the retention arithmetic is sensitive to assumptions the book does not stress.
Key takeaways 7
- A retained customer becomes more profitable over time through amortised acquisition cost, growing purchase volume, falling service cost, referrals and price premium.
- Small improvements in retention rate produce large increases in customer lifetime value, because the effects compound across several channels at once.
- Employee turnover destroys the relationship knowledge that customer retention depends on, so the two cannot be managed separately.
- Fast-turnover shareholders push management toward decisions that damage customer and employee retention, which makes investor loyalty part of the same system.
- Most companies do not measure retention accurately because they count transactions rather than relationships and do not track customers who leave.
- Referrals from existing customers acquire new customers at no cost and with better retention characteristics than paid acquisition produces.
- Growth achieved by acquiring customers who will not stay destroys value while appearing in every reported metric as success.
