How to Calculate Survey Response Rate

The response rate measures what fraction of distributed surveys were returned.

Formulas

Response Rate = Responses / Surveys Sent x 100

Usable Rate = (Responses - Incomplete) / Surveys Sent x 100

Completion Rate = Usable / Total Responses x 100

Benchmarks

  • Online surveys: 20-30% is typical
  • Mail surveys: 30-50%
  • In-person surveys: 50-80%
  • Response rates below 20% raise concerns about non-response bias.

    • Exemple Résolu

    500 surveys sent, 175 responses received, 25 incomplete.

    1. Response rate: 175 / 500 x 100 = 35.0%
    2. Usable responses: 175 - 25 = 150
    3. Usable rate: 150 / 500 x 100 = 30.0%
    4. Completion rate: 150 / 175 x 100 = 85.7%
