About Customer Effort Score Calculator

Customer effort score asks how easy it was to get an issue resolved, and it predicts loyalty better than satisfaction in service contexts. Normalising to a percentage lets scores from different scale lengths be compared.

Formula

Effort score

Average = sum of scores / responses; normalised = average / scale maximum × 100

  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates based on the inputs given. Marketing performance, platform fees and conversion behaviour vary by audience, channel and season. Use this as a planning guide, not a forecast.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.
