Calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) to understand your daily calorie needs based on your age, sex, weight, height, and activity level.
Basal Metabolic Rate (BMR)
0 calories/day
Total Daily Energy Expenditure (TDEE)
0 calories/day
Maintenance Calories
0 calories/day
How It Works
This calculator uses the Mifflin-St Jeor equation, which is one of the most accurate methods for calculating BMR. The equation takes into account your age, sex, weight, and height to determine how many calories your body burns at rest.
Understanding Your Results
BMR (Basal Metabolic Rate): The number of calories your body needs to perform basic life-sustaining functions while at rest.
TDEE (Total Daily Energy Expenditure): Your BMR multiplied by your activity level factor, representing the total calories you burn in a day.
Maintenance Calories: The number of calories you need to consume to maintain your current weight (same as TDEE).
How to Use Your Results
To maintain weight: Consume calories equal to your TDEE
To lose weight: Consume 300-500 calories less than your TDEE (safe deficit)
To gain weight: Consume 300-500 calories more than your TDEE (safe surplus)
