Calorie Calculator
Estimate daily calories (BMR & TDEE) from age, height, weight, and activity
Daily calorie needs
Estimates your Basal Metabolic Rate (BMR) with the Mifflin-St Jeor equation and your Total Daily Energy Expenditure (TDEE) by applying an activity multiplier. TDEE is roughly the calories needed to maintain your current weight. Calculated locally in your browser.
FAQ
What's the difference between BMR and TDEE?
BMR is the energy you'd burn at complete rest. TDEE multiplies BMR by an activity factor to account for daily movement and exercise — it's the better target for maintenance calories.
How do I lose or gain weight?
A deficit of about 500 calories/day under your TDEE targets roughly 0.5 kg loss per week; a similar surplus supports gradual gain. The result box shows both.
Is this medical advice?
