The median annual wage of dietitians and nutritionists was $53,250 in May 2010. The median annual wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $33,330, and the top 10 percent earned more than $75,480.
Most dietitians and nutritionists work full time, although about 20 percent work part time. Self-employed, consultant dietitians have more flexibility in setting their schedules.
