Customer Effort Score (CES) ROI Calculator
Customer Effort Score (CES) predicts loyalty 1.8x better than CSAT per HBR research. Calculate revenue impact of improving CES from 5 to 6 — retention lift, expansion lift, and support cost reduction.

Customer Effort Score (CES) — measured by 'How easy was it to solve your problem?' on a 1-7 scale — predicts customer loyalty 1.8x better than CSAT or NPS per HBR research. Reducing customer effort lifts retention 3-5 points per CES point and cuts support volume 8-12% per CES point. Calculate the revenue impact of moving CES from 5 to 6.
Why CES Beats CSAT and NPS
HBR research by Dixon et al. studied 75,000 customers and found CES predicts repeat purchase 1.8x better than CSAT and 1.4x better than NPS. The insight: customers don't care about delight — they care about effort. A frictionless renewal beats a delightful gift basket. Apply CES to the moments that matter: onboarding, support resolution, billing, renewal. These are the high-effort moments that drive churn or loyalty.
How to Reduce Effort
(1) Self-serve documentation: well-indexed knowledge base reduces 'how do I' tickets 25-40%. (2) In-app guidance: tooltips and walkthroughs reduce confusion at first-use. (3) Single-touch resolution: support agents trained to solve in one contact reduce CES dramatically. (4) Frictionless renewal: auto-renew default, one-click portal, transparent pricing. Each lever moves CES 0.3-0.7 points; combined improvements of 1+ points are common within six months.
