Welcome to the Community @Amanagar96. The calorie burn you are seeing is the result of your Basal Metabolic Rate (BMR). Your BMR is the rate at which you burn calories as a result of maintaining vital body functions. These functions include breathing and heartbeat and brain activity, among others. Your BMR usually accounts for at least half of the calories you burn in a day.
When you created your Fitbit profile, you entered your gender, age, height and weight. Your profile and tracker use that data to configure your daily BMR.
I hope this helps, let me know the outcome.
