How to Calculate Response Rate: 5 Easy Steps & Formula

Written by Alvin Amoroso | 7/24/25 1:24 PM

Knowing how to calculate response rate is a fundamental skill for anyone involved in gathering feedback, whether through surveys, marketing campaigns, or customer outreach. The simplest way to do this is by dividing the number of people who responded by the total number of people you contacted, and then multiplying that result by 100 to get a percentage. This single metric can tell you a powerful story about your audience's engagement and the effectiveness of your communication strategy.

In this comprehensive guide, we will walk you through everything you need to know. We'll start with a clear response rate definition, provide the exact formula with step-by-step instructions, show you real-world examples, and share expert strategies to improve your future survey response rates. By the end, you'll not only be able to calculate response rate accurately but also understand how to use it to make smarter, data-driven decisions.

What is a Response Rate? 

Before you learn the calculation, it's essential to understand the core response rate definition. The response rate is a metric expressed as a percentage that measures the number of people who completed a desired action (like finishing a survey) out of the total number of people who were asked to do so. In simple terms, it’s the percentage of your target audience that actually engaged and responded.

For example, if you send an email survey to 200 customers and 50 of them complete it, your response rate is 25%. This metric is a critical indicator of engagement, interest, and the overall success of your data collection efforts. A high response rate generally suggests that your survey was well-designed, relevant to the audience, and distributed effectively. Conversely, a low rate might signal issues with your questions, your delivery method, or your audience targeting.

Why is it Crucial to Calculate Response Rate?

Understanding how to calculate response rate goes far beyond just getting a number; it provides critical insights that can shape your strategies. Calculating this metric is crucial because it directly reflects the quality and reliability of your data.

  1. Indicates Data Validity: A higher response rate often leads to more accurate and representative data. If only a small fraction of your intended audience responds, your results may be skewed by nonresponse bias, where the group that responded differs significantly from the group that did not. This can lead to flawed conclusions and misguided business decisions.
  2. Measures Engagement and Relevance: Your response rate is a direct reflection of how engaging and relevant your audience finds your content. Low rates can be a red flag, indicating that your subject line didn't grab attention, your questions were confusing, or the topic simply wasn't important to the recipients.
  3. Evaluates Campaign Effectiveness: For marketers and researchers, the response rate is a key performance indicator (KPI) for evaluating the success of a survey or outreach campaign. By tracking this metric over time, you can test different approaches and identify which strategies—like timing, messaging, or incentives—work best for your audience.
  4. Helps Optimize Future Efforts: Analyzing why a response rate was high or low provides valuable lessons. Did personalization work? Was the survey too long? By learning from this data, you can refine and improve your future survey response rates, saving time and resources while gathering better insights.

The Simple Formula to Calculate Response Rate

At its core, the process to calculate response rate is straightforward. The formula requires only two pieces of information: the number of people who responded and the total number of people in your sample.

The universal formula is:

Let's break down the components:

  • Number of Responses: This is the total count of individuals who successfully completed and submitted the survey or action. It's crucial to only count completed or substantially completed responses, depending on your criteria.
  • Total Number of People in Sample: This is the total number of people you successfully contacted and invited to participate. This number should exclude any "bounces" or invalid contacts. For example, if you sent 1,000 emails but 50 of them bounced, your total sample size is 950, not 1,000.

Using this formula will give you a percentage, which is the standard way to represent a response rate.

How to Calculate Response Rate: A 5-Step Guide

Now that you understand the formula, let's walk through the practical process. Following these five steps will ensure you calculate response rate accurately every time.

Step 1: Determine the Total Number of People Surveyed

The first step is to identify your total sample size. This isn't just the number of emails you sent, but the number of people who successfully received your invitation. You must clean your list by removing any undeliverable contacts.

  • For Email Surveys: Subtract the number of hard bounces (invalid email addresses) from your total send list.
  • For Direct Mail Surveys: Subtract any mailers that were returned as "undeliverable."
  • For Phone Surveys: Subtract any disconnected or invalid numbers.

The final number is your true sample size. Let's say you emailed 5,000 people and 200 emails bounced. Your total sample size is 4,800.

Step 2: Count the Number of Completed Responses

Next, you need to count how many people actually responded. Define what a "response" means for your project. Does it mean the person answered every single question, or is answering 80% of the questions sufficient? Be consistent with your definition.

Most modern tools, like a comprehensive survey software, will automatically track this for you. For our example, let's say you received 960 completed surveys.

Step 3: Apply the Response Rate Formula

With your two numbers, you can now apply the formula. Divide the number of responses by your total sample size.

Using our example:

Step 4: Convert the Result to a Percentage

The result from Step 3 is a decimal. To make it easily understandable, convert it into a percentage by multiplying it by 100.

Continuing our example:

Your survey response rate is 20%.

Step 5: Analyze and Interpret Your Rate

The final step is to analyze what this number means. A 20% response rate could be excellent for an external marketing survey but might be low for an internal employee feedback survey. Compare your rate to industry benchmarks and your own historical data. Use this insight to evaluate the success of your project and identify areas for improvement. For complex datasets, consider using expert data analysis services to uncover deeper trends.

Real-World Examples of Calculating Response Rate

Let's apply the formula to a few different scenarios to solidify your understanding.

Example 1: Customer Feedback Email Survey

  • You send a feedback survey to 1,200 customers.
  • 75 emails bounce back as undeliverable.
  • You receive 225 completed surveys.
  • Step 1: Total Sample = 1,200 - 75 = 1,125
  • Step 2: Number of Responses = 225
  • Step 3 & 4: Response Rate = (225 / 1,125) * 100 = 20%

Example 2: In-App Pop-Up Survey

  • A pop-up survey is shown to 10,000 unique app users.
  • 1,500 users click "submit" after answering the questions.
  • Step 1: Total Sample = 10,000
  • Step 2: Number of Responses = 1,500
  • Step 3 & 4: Response Rate = (1,500 / 10,000) * 100 = 15%

Example 3: Direct Mail Survey for a Political Campaign

  • A campaign sends 20,000 flyers with a QR code to a survey.
  • 500 are returned by the post office as "return to sender."
  • The campaign receives 800 completed online surveys via the QR code.
  • Step 1: Total Sample = 20,000 - 500 = 19,500
  • Step 2: Number of Responses = 800
  • Step 3 & 4: Response Rate = (800 / 19,500) * 100 = 4.1%

What is a Good Survey Response Rate? 

One of the most common questions after you calculate response rate is, "Is my rate good?" The answer is: it depends. What constitutes "good" survey response rates varies widely based on the survey method, the target audience, the industry, and the relationship you have with the respondents.

Here are some general benchmarks to give you context:

  • Internal Surveys (e.g., employee satisfaction): 30% to 40% is considered good, but rates can often exceed 50% in highly engaged organizations.
  • External B2C Surveys (e.g., customer feedback): 10% to 20% is often a realistic target. Response rates can be lower if there's no existing relationship with the customer.
  • External B2B Surveys (e.g., market research): 20% to 35% is a strong range. B2B audiences are smaller and often more invested, but their time is also more limited.
  • Lead Generation Surveys: 5% to 15% is typical. The goal is often volume, and the audience may have less motivation to respond.
  • Academic or Research Surveys: Response rates can vary dramatically, but established research organizations like the Pew Research Center often achieve high rates through rigorous methodology.

Remember, these are just guidelines. The most important benchmark is your own historical performance. Always aim to improve upon your previous results.

7 Actionable Strategies to Improve Your Survey Response Rates

If your response rate is lower than you'd like, don't worry. There are many proven strategies you can implement to encourage more people to participate. Improving your survey response rates is key to gathering higher-quality data.

1. Personalize Your Outreach

Address recipients by their first name in emails. Mention a recent interaction they had with your company. Personalization shows you value them as an individual, not just a data point, and can significantly lift open and response rates.

2. Keep the Survey Short and Simple

Respect your audience's time. A survey that takes 20 minutes will have a much lower response rate than one that takes 3-5 minutes. Only ask essential questions. A key part of this is writing effective survey questions that are clear, concise, and easy to answer.

3. Offer a Compelling Incentive

An incentive can be a powerful motivator. This could be a discount code, a gift card, a free resource, or entry into a prize drawing. Ensure the incentive is relevant and valuable to your specific audience.

4. Optimize for Mobile Devices

A significant portion of your audience will open your survey on a smartphone. If the survey is difficult to navigate on a small screen—requiring pinching, zooming, or excessive scrolling—they will abandon it. Ensure your survey platform is fully mobile-responsive.

5. Send Strategic Reminders

People are busy and often forget. Sending one or two polite reminder emails to non-respondents can dramatically boost your final numbers. Time your reminders carefully—a few days after the initial send and perhaps a day before the survey closes.

6. Choose the Right Time and Channel

Think about when and where your audience is most likely to be receptive. For a B2B audience, sending a survey mid-week during business hours might be best. For a B2C audience, an evening or weekend might work better. Test different channels like email, SMS, or social media to see what yields the best results.

7. A/B Test Your Subject Lines and Questions

Don't guess what works best—test it. Use A/B testing on your email subject lines to see which one gets more opens. You can also test different versions of a question to see which one is clearer and easier for people to answer.

Response Rate vs. Completion Rate vs. Answer Rate: Key Differences

The terminology around survey metrics can be confusing. While "response rate" is the most common, you might also hear about "completion rate" and "answer rate." Understanding the difference is crucial for accurate analysis.

  • Response Rate: The percentage of people who responded out of the total sample size you contacted. (Responders / Total Sample).
  • Completion Rate: The percentage of people who finished the survey out of those who started it. If 1,000 people clicked the survey link but only 700 finished it, your completion rate is 70%. This metric helps you identify if your survey is too long or has confusing questions that cause people to drop off.
  • Answer Rate (or Item Response Rate): The percentage of respondents who answered a specific question within your survey. If 700 people completed your survey but only 600 answered an optional demographic question, the answer rate for that specific question is about 86%. This helps you identify problematic or sensitive questions.

While all are useful, the overall response rate remains the primary metric for judging the initial success of your outreach.
