For a registered dietitian to estimate his or her earnings potential, all it takes is a simple online form from the Academy of Nutrition and Dietetics. The calculator asks the user to provide info such as education level, years of experience, certifications held, gender, and geographic location. With 11 drop-down choices and four checkboxes, the form takes barely a minute to complete. Click “Calculate” and—presto!—the page displays an expected hourly wage and annual salary, based on the Academy’s biannual compensation research. The simple interface makes it easy to adjust individual variables and see how changes would affect a dietitian’s pay.
