How to Calculate Response Rate in a Survey
Calculating your survey response rate is a critical metric for determining the validity and reliability of your data. Whether you are conducting market research, employee satisfaction polls, or customer feedback forms, understanding the percentage of people who participated versus those invited helps measure the effectiveness of your campaign.
The Survey Response Rate Formula
The core formula for calculating response rate is straightforward. It represents the ratio of completed surveys to the total number of people included in the sample.
Response Rate = (Number of Completed Surveys / Number of Invitations Sent) × 100
For a more accurate calculation, professional researchers often use the Adjusted Response Rate. This excludes "bounced" emails or undeliverable invitations from the total count, as those individuals never actually had the opportunity to respond.
Adjusted Rate = (Completed Surveys / (Invitations Sent – Undeliverable)) × 100
Example Calculation
Let's say you sent out an email survey to your customer base regarding a new product launch.
- Total Emails Sent: 1,000
- Bounced Emails (Undeliverable): 50
- Completed Surveys: 150
First, calculate the effective sample size: 1,000 – 50 = 950.
Next, divide the responses by the effective sample: 150 / 950 = 0.1578.
Finally, multiply by 100 to get the percentage: 15.78%.
What is a Good Survey Response Rate?
Benchmarks vary significantly depending on the channel, audience, and industry. Here are general guidelines:
External Surveys (Customers/Market Research)
- 5% to 10%: Average. Typical for cold audiences or long generic surveys.
- 10% to 20%: Good. Indicates a relationship with the brand.
- Above 20%: Excellent. Usually requires high incentives or loyal customers.
Internal Surveys (Employees)
- 30% to 40%: Average.
- 60% to 80%: Good.
- Above 80%: Excellent. Suggests a strong company culture of feedback.
Factors Influencing Your Rate
If your calculator results show a low percentage, consider these factors:
- Survey Length: Surveys taking longer than 5 minutes see high drop-off rates.
- Incentives: Offering a discount, gift card, or entry into a raffle can boost rates by 5-20%.
- Relevance: Ensure the survey topic matters to the recipient.
- Timing: Mid-week sends (Tuesday-Thursday) often perform better than weekends.
