Calorie Calculator
Calculate BMR and TDEE from your body stats and activity level.
Get personalized calorie targets for diet, maintenance, or muscle gain.
About
A free tool that calculates your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) from your height, weight, age, gender, and activity level using the revised Harris-Benedict formula.
Set calorie targets for weight loss, maintenance, or muscle gain. All calculations run locally in your browser — no personal data is transmitted.
How to Use

View Results
BMR, TDEE, and goal-based calorie targets are automatically calculated.
Glossary
- BMR (Basal Metabolic Rate)
- Calories burned at rest to maintain basic life functions such as heartbeat, breathing, and body temperature.
- TDEE (Total Daily Energy Expenditure)
- BMR multiplied by an activity factor — the total calories you burn in a day.
- Harris-Benedict Equation
- A 1919 formula, revised in 1984, widely used to estimate BMR from body measurements.
- Activity Multiplier
- A factor (1.2–1.9) representing your weekly exercise intensity applied to BMR to get TDEE.
- Caloric Deficit
- Consuming fewer calories than your TDEE — required for weight loss.
- Caloric Surplus
- Consuming more calories than your TDEE — used for muscle gain (bulking).
FAQ
- Q.Mes données sont-elles envoyées à un navigateur ?
- Non. Tous les calculs sont exécutés localement dans votre navigateur.
- Q.Quelle est la précision des résultats ?
- La formule révisée de Harris-Benedict fournit des estimations. Le métabolisme réel varie en fonction de la masse musculaire, de la graisse corporelle et de la génétique.
- Q.Comment puis-je définir un objectif de réduction (perte de poids) de calories ?
- Un déficit d’environ 500 kcal/jour en dessous du TDEE est couramment utilisé, entraînant une perte de poids d’environ 0,5 kg/semaine.
- Q.Est-ce adapté aux adolescents ?
- La formule est conçue pour les adultes. Les adolescents devraient consulter un médecin ou un diététiste.
