BMR Calculator
Calculate your Basal Metabolic Rate (BMR) to understand your body's daily energy needs at rest.
Understanding BMR and TDEE
Your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) are crucial metrics for understanding your body's energy needs.
Basal Metabolic Rate (BMR)
BMR is the number of calories your body burns at rest to maintain basic life functions like breathing, circulation, and cell production.
For Men: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age + 5 For Women: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age - 161
BMR forms the basis for determining your daily calorie needs.
Total Daily Energy Expenditure (TDEE)
TDEE is your total daily calorie burn when accounting for your activity level.
TDEE = BMR × Activity Level Multiplier
Activity Multipliers
- Sedentary: BMR × 1.2
- Light Activity: BMR × 1.375
- Moderate Activity: BMR × 1.55
- Active: BMR × 1.725
- Very Active: BMR × 1.9
Factors Affecting BMR
- Age: BMR typically decreases with age
- Gender: Men generally have a higher BMR than women
- Body Composition: More muscle mass increases BMR
- Height and Weight: Larger bodies require more energy
- Genetics: Individual variations can affect BMR
