BMR & TDEE Calculator
Find out exactly how many calories your body burns every day.
Your Profile
Maintenance Calories (TDEE)
2,598 kcal/day
Basal Metabolic Rate (BMR): 1,676 kcal
Daily Calorie Goals
* BMR is calculated using the Mifflin-St Jeor equation. TDEE (Total Daily Energy Expenditure) is an estimate of how many calories you burn per day when exercise is taken into account.
The Science of Weight Loss
Weight management comes down to a simple equation: Calories In vs. Calories Out. Your TDEE (Maintenance Calories) is your "Calories Out". If you eat fewer calories than your TDEE, you will lose weight. If you eat more, you will gain weight.
BMR vs. TDEE
Basal Metabolic Rate (BMR)
The calories your body burns at rest just to keep you alive (breathing, pumping blood, brain function). It accounts for about 60-75% of your total daily calorie burn. You should never eat fewer calories than your BMR.
Total Daily Energy Expenditure (TDEE)
Your BMR plus the calories you burn through daily movement and exercise. This is your true maintenance level. Eating this exact amount will keep your weight perfectly stable.
Frequently Asked Questions
Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions, such as breathing, circulation, and cell production.
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 multiplying your BMR by an activity multiplier.
To lose 1 pound of fat per week, you need a caloric deficit of about 3,500 calories per week, which equals 500 calories per day less than your TDEE.
