Calorie Calculator
Calorie calculator helps you determine your daily caloric needs based on your age, gender, weight, height, and activity level. Calculate your BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure) to understand how many calories you need for weight maintenance, loss, or gain. Get personalized calorie targets to support your health and fitness goals.

Important Note:
These calculations are estimates. For personalized nutrition advice, especially if you have health conditions or specific goals, consult with a healthcare professional or registered dietitian. Healthy weight loss is typically 0.5-1 kg per week.
Frequently Asked Questions
- What is BMR?
- BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest. It's the energy needed for basic functions like breathing, circulation, and cell production. BMR typically accounts for 60-75% of your total daily calorie expenditure.
- What is TDEE?
- TDEE (Total Daily Energy Expenditure) is your BMR multiplied by your activity level. It represents the total calories you burn in a day including exercise and daily activities. TDEE is your maintenance calorie level.
- How many calories should I eat to lose weight?
- For healthy weight loss, aim for 500 calories below your TDEE, which typically results in losing about 0.5 kg (1 lb) per week. Avoid going below 1200 calories/day for women or 1500 for men without medical supervision.
- Which formula does this calculator use?
- This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR. It accounts for age, gender, weight, and height.
- Why does gender affect calorie needs?
- Males typically have more muscle mass and less body fat than females, resulting in a higher BMR. Muscle tissue burns more calories at rest than fat tissue, so biological differences affect baseline calorie needs.
- How accurate is this calculator?
- This calculator provides estimates based on validated formulas. Individual metabolism can vary by 10-15% due to genetics, body composition, hormones, and other factors. Use these numbers as a starting point and adjust based on your results over time.
