The IndustryWeek salary calculator is a combination of the actual IW Salary Survey data, which include responses from 1,400 participants, bolstered by predictive analytics. It’s meant to complement the actual salary data, but it isn’t meant to be an exact representation of potential earnings.
The IW salary calculator includes eight possible fields. You may select a response for each field, or you may exclude a field simply by leaving "No Answer" in the response area.
