Walking 2,000 steps, or the equivalent of 1 mile, burns approximately 100 calories, according to Shape Up America. This figure is for an average American with an average stride. The exact number of calories burned by walking depends on the walker's age, weight, motion while walking and fitness level, explains About Health, which approximates that a 150-pound person expends 80 calories by walking between 2,000 and 2,500 steps.
