SurveyReflex offers a set of standalone utilities you can use without creating an account. There is nothing to install and no sign-up required — just open the tool, enter your numbers or topic, and get an instant result.
All five tools are available at surveyreflex.com/tools.
NPS Calculator
URL: surveyreflex.com/tools/nps-calculator
Net Promoter Score is one of the most widely used customer loyalty metrics, but calculating it by hand is error-prone. Enter your raw counts of Promoters, Passives, and Detractors and the calculator instantly computes your NPS along with a plain-English interpretation of what the score means.
Useful for anyone who has already collected NPS survey data and wants a quick, shareable number.
Sample Size Calculator
URL: surveyreflex.com/tools/sample-size-calculator
Before you launch a survey, you need to know how many responses to collect for your results to be statistically meaningful. Set your desired confidence level and acceptable margin of error, and the calculator tells you the minimum sample size you need.
Use this before purchasing a response package to make sure you are buying the right amount.
Survey Question Generator
URL: surveyreflex.com/tools/question-generator
Staring at a blank survey is frustrating. This AI-powered tool helps you get started quickly. Choose a category, describe what you are trying to learn, and the generator produces eight professionally phrased survey questions tailored to your goal.
You can copy the questions directly into your SurveyReflex survey builder or use them as a starting point for your own edits.
Cost of Churn Calculator

Customer churn has a direct impact on revenue, but the full annual cost is often larger than it appears. Enter your key business metrics and the calculator shows you how much revenue churn is costing you each year — and how much you could recover by improving customer satisfaction through regular feedback.
A useful tool for building an internal business case for customer research.
