Cover Letter Score and Checks

Cover Letter Score 93%

How we calculate this score

AI gives each category a score out of 100. Some categories count more toward the final score:

  • Job relevance — 30%
  • Supporting examples — 25%
  • Personalization — 20%
  • Clarity — 15%
  • Structure — 10%

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.

What this score means

Our cover-letter score is an AI-assisted estimate, not an employer rating. It may contain errors and does not guarantee an interview or a job. Check the feedback before relying on it. You are responsible for relying on this score.
