How to Calculate & Formula Details
Mathematical Model Formula
BMR calculated via Mifflin-St Jeor equation, then multiplied by an activity multiplier (1.2 to 1.9) to find TDEE.A calorie calculator helps you determine your Total Daily Energy Expenditure (TDEE) — the total number of calories your body burns in a day. Knowing your TDEE is the starting point for any nutrition plan, whether you want to lose weight, maintain weight, or build muscle.
Basal Metabolic Rate (BMR) vs. TDEE
Your BMR is the number of calories your body burns at complete rest just to keep you alive (breathing, pumping blood, cell production). TDEE takes your BMR and adds the energy burned through daily activity and exercise.
Mifflin-St Jeor Equations
- Men: BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age (y) + 5
- Women: BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age (y) - 161
