B2B Sample Size Calculator

Devised especially for business-to-business research, in which there are limited numbers of companies in the universe, our Sample Size Calculator will tell you how many companies you need to interview for a valid sample.

Using the Sample Size Calculator

  1. Select your ‘population size’ (i.e. your estimate of the total number of companies in the market).
  2. The ‘sample size’ box will automatically show the number of companies you need to interview.

The ‘sample size’ is the number of companies you need to survey to achieve a response that is accurate to within 5% (and to 95% confidence).
