- What the source says
By retaining a mere 5% more customers, e-companies can boost profits by 25–95%
- Method & sample
- Bain analysis of e-business economics, dot-com era (Reichheld & Schefter, HBR July–Aug 2000). The figure is often credited to the earlier 1990 HBR paper 'Zero Defections' (Reichheld & Sasser), but that paper gives a different range, 25–85%, from a handful of service businesses (85% in one bank's branch system, 50% in an insurance brokerage, 30% in an auto-service chain), for a 5-point cut in the defection rate, and its chart measured customer value (net present value of the average customer's profit stream), not company-wide profit.
- Drift between quote and source
- Population: e-companies in 2000 → every business today
- Attribution: the 25–95% range comes from the 2000 e-loyalty article; the 1990 'Zero Defections' paper often cited for it says 25–85%
- Metric: the 1990 figures measured value per customer (NPV of the profit stream), widely re-quoted as total company profit
- Date: 26 years old (36 for the 1990 cases)
- Interest
- Bain sells loyalty consulting (Net Promoter).
Safe rephrasing
Bain's Reichheld estimated in 2000 that retaining 5% more customers could lift e-commerce profits by 25–95%; his 1990 HBR cases (bank, insurance, auto service) showed 25–85% gains in customer value. The effect varies by industry, so model it with your own retention and margin data.
