How accurate are calorie counters on a treadmill?

When you enter your age, weight, and time on a treadmill how accurate is the calorie counter. After the time has expired if it reflects 300 calories, is it very accurate?

Recommended Answer:

About 20 - 30 percent either way is as accurate as they can be, and one would expect manufacturers to want to overestimate, giving you a sense that their machine is more effective.They are not really calorie "counters," but calorie "estimators." They have a memory bank of the rate at which a typical person of any given age and weight might burn at any given level of exercise intensity.There are no official standards, nor is there an accepted verification process. So you can expect the number they tell you to be only a rough guess. In addition, any comparability is limited to sessions on the same machine - you can't expect "500 calories" on one treadmill to be the same as "500 calories" on another treadmill.
