Estimate your basal metabolic rate and daily calorie needs with a free BMR and TDEE calculator. Compare calorie targets for weight loss, maintenance, or weight gain.
Educational use only. Tool outputs have important limitations and cannot replace an individual assessment by an appropriately qualified healthcare professional.
Estimate BMR, TDEE, and daily calorie needs
Basal metabolic rate estimates the energy the body uses at rest. Total daily energy expenditure applies an activity estimate to explore possible daily calorie needs. The calculator supports metric and imperial measurements.
How to interpret the estimate
BMR and TDEE formulas are population estimates, not exact measurements or individualized nutrition plans. Activity level, health conditions, pregnancy, age, body composition, and other factors can change actual energy needs.
