Which calculator do I need?
Before you send your survey
Start with the sample size calculator to find out how many completed responses you need. Combine that number with the response rate you expect and you know how many people to invite.
While responses are coming in
Use the response rate calculator to track how many of the people you invited have taken part, and to decide whether a reminder is worth sending.
When you analyse the results
The margin of error and significance calculator tells you how precise a percentage is and whether a difference between two groups is likely to be real. For rating questions and other numeric answers, the mean, median and mode calculator gives you the average, the middle value and the spread.
When you report a score
Calculate customer loyalty with the NPS calculator, employee loyalty with the eNPS calculator, and satisfaction with a specific experience with the CSAT calculator.
