How we calculate this score

  • Job relevance — 30%
  • Supporting examples — 25%
  • Personalisation — 20%
  • Clarity — 15%

Your final score

We multiply each category score by its weight, add the results, and round to the nearest whole number. If a category cannot be assessed, we leave it out and share its weight across the remaining categories.

This score reviews the letter as it was generated. Editing the letter does not update it automatically. This is a cover-letter review, not an ATS keyword score.
