Calculate - BMI/BMR/TDEE

Learn exactly how many calories you need each day! In just a few seconds you can calculate the exact number of calories you should eat each day. Whether you are looking to lose weight or gain weight, learning your daily calorie needs is crucial to getting results!

Your Total Daily Energy Expenditure (TDEE) is an estimation of how many calories you burn per day when exercise is taken into account. It is calculated by first figuring out your Basal Metabolic Rate, then multiplying that value by an activity multiplier.


Since your BMR represents how many calories your body burns when at rest, it is necessary to adjust the numbers upwards to account for the calories you burn during the day. This is true even for those with a sedentary lifestyle. Our TDEE calculator uses the best formulas and displays your score in a way that's easy to read and meaningful.

Activity Level

Activity level:

Activity level is a factor that is based on the amount of activity a person undergoes. This includes deliberate exercise as well as other activities that a person may undergo as part of their job or typical daily activities. These factors are more specifically referred to as the thermic effect of activity, and non-exercise activity thermogenesis (energy expended for non-sleeping, eating, or sports-like exercise).

Thermic effect of food:

The thermic effect of food, also referred to as specific dynamic action, is the amount of energy required by the body to process and use food. It is sometimes estimated as 10% of food energy intake, but this can vary significantly depending on the type of food consumed. Protein, for example, has a far larger thermic effect than dietary fat, since it is more difficult to process.
