Formulas Used

Overall Response Rate

response_rate = responses_received / surveys_sent * 100

Usable Response Rate

usable_rate = usable_responses / surveys_sent * 100

Completion Rate

completion_rate = usable_responses / responses_received * 100

Usable Responses

usable_count = usable_responses

How It Works

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.

    • Worked Example

    500 surveys sent, 175 responses received, 25 incomplete.

    surveys_sent = 500responses_received = 175incomplete_responses = 25
    1. 01Response rate: 175 / 500 x 100 = 35.0%
    2. 02Usable responses: 175 - 25 = 150
    3. 03Usable rate: 150 / 500 x 100 = 30.0%
    4. 04Completion rate: 150 / 175 x 100 = 85.7%
