    Survey Completion Rate

    Completion rate is the percentage of survey starters who finished all questions.

    Distinct from response rate — completion measures how many of the people who STARTED also FINISHED. Drop-off between start and finish reveals friction in the survey design. Long surveys, sensitive questions, and unclear wording all cause incompletion.

    Formula

    Completion Rate (%) = (Finished surveys / Started surveys) × 100
