BMR Calculator

You use energy (burn calories) no matter what you are doing, even while sleeping. This calculator will help you determine your Basal Metabolic Rate (BMR), which is the number of calories you would burn everyday even if you were to stay in bed (we do not recommend that!). This formula is based on multiple factors, which makes it more accurate than calculating calorie needs based on body weight alone. Remember, bodies that have more lean muscle burn more calories than those with less. Thus, for the very fit and those classified as obese, this formula will not be as accurate as with those falling in between.
