It uses your account settings (height, weight, and age) and utilizes your heart rate to decide how many calories. It looks at how long you are in the fat burn, cardiac, or high peak zone and takes that into account. Steps alone don't really burn that many calories unless you are walking intensely and increase your heart rate or if you are walking at least 8,000 steps/day to burn some more calories. Hope this helps.
Sorry, there was a problem.

Your BMR usually accounts for at least half of the calories you burn in a day and is estimated based on the physical data you entered when you set up your account: gender, age, height, and weight. The calorie burn estimate that Fitbit provides takes into account your BMR, the activity recorded by your tracker, and any activities you log manually. If your tracker measures heart rate, the calorie burn estimate also takes heart rate into account. Your tracker's calorie count will reset each night at midnight and begin counting immediately thereafter. BMR is the reason your tracker starts the day with calories already burned—even if you haven't been active yet, you've still burned calories just by being alive."
Sorry, there was a problem. Please try again later.Its strictly *calculating* calories burned - it does not 'know'. Ie.- if you put your height/weight into your profile, it will make assumptions based on your base metabolic rate and your activity rate to calculate approx. calories burned. Yes, it will tell you how many calories burned per day - and even those you burned while sleeping.

Sorry, there was a problem. Please try again later.I believe it depends on your level of activity and steps taken.
Sorry, there was a problem. Please try again later.The factors that are taken into consideration are height, weight, placement of device, and the sensitivity of the sensor. All of this info is needed to accurately calculate calories burned. On fitbit.com you will go to the dashboard and get into the settings. From there is where you can fine tune your device.
Sorry, there was a problem. Please try again later.I think it also takes your HR into consideration when calculating your calories.
Sorry, there was a problem. Please try again later.Not by steps alone. Once you set it up and sync it (online), it will enter "typical" calories burned for activities you enter. These can also be modified (online) for what you think you burned in calories. You have to enter the activities under the "exercise" button/tab (w/ your smart phone), along with the duration, and it will give you the number of calories expended in that activity.
Sorry, there was a problem. Please try again later.No it tracks more than just your steps. I think it must use your heart rate as part of the formula. It also tracks flight of stairs you climb.
Sorry, there was a problem. Please try again later.you can fake it out just by shaking your arms but that is cheating, the calories are defined i believe by your steps and other information you put it. I.E. weight, Ht. ect.
