Calculate your daily calorie needs using BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure). Perfect for meal planning, weight management, and fitness goals.
BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic physiological functions like breathing, circulation, and cell production. It represents the minimum energy your body needs to function.
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn in a day, including BMR plus calories burned through physical activity. TDEE = BMR × Activity Level Multiplier. This is the number of calories you need to maintain your current weight.
To lose weight, consume fewer calories than your TDEE (typically 500-1000 calories less per day for 1-2 lbs per week). To gain weight, consume more calories than your TDEE (typically 300-500 calories more per day). Always consult with a healthcare professional before making significant dietary changes.
Choose the activity level that best describes your typical week: Sedentary (little/no exercise), Light (exercise 1-3 days/week), Moderate (exercise 3-5 days/week), Active (exercise 6-7 days/week), or Very Active (hard exercise daily or physical job).
The calculator uses the Mifflin-St Jeor Equation, which is considered one of the most accurate BMR formulas. However, individual metabolism varies, and these are estimates. Factors like muscle mass, genetics, and medical conditions can affect actual calorie needs.
You can use either system - the calculator supports both metric (kg/cm) and imperial (lbs/inches) units. Simply select your preferred unit system and enter your measurements. The calculations are identical regardless of which system you use.
