Reading your Customer Effort Score
CES distils one thing into a single number — how hard your customers had to work to get helped. Here's how it's calculated, what a good score looks like, and how it differs from CSAT and NPS.
How CES is calculated
After an interaction you ask one question — “[Company] made it easy to handle my issue” — on a 7-point scale (1 strongly disagree → 7 strongly agree). There are two ways to score the answers: take the average rating, or report the % who agreed (the top boxes). The calculator does both.
CES = Σ ratings ÷ responses
Average method
% easy = agree (5–7) ÷ total × 100
% easy (top-box) method
What a good CES looks like
On a 7-point average, the scale runs 1 to 7 — and your live result lands on this same axis the moment you calculate. (On the % easy method, the bands are 80%+ excellent, 65–79% good, 50–64% moderate, and below 50% high effort.)
Excellent — Top-tier. Customers find it genuinely easy to get help.
Good — Solid. Most interactions feel low-effort to your customers.
Moderate — Workable, but customers are hitting friction worth removing.
High effort — Customers are working too hard — a clear churn risk.
CES vs CSAT vs NPS
All three are one-question surveys, but they measure different things at different moments. CES is the best leading indicator for support: high effort predicts churn before satisfaction even drops.
Use CES right after a support conversation, CSAT for a specific touchpoint, and NPS for the overall relationship. Most teams run CES with one of the others rather than choosing a single metric — calculate all three with the CSAT and NPS calculators.
