Calorie Calculator

A calorie calculator is a tool that estimates your daily calorie needs based on factors like age, gender, height, weight, and activity level. It calculates your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) to help you understand how many calories you need to maintain, lose, or gain weight.

Calorie calculators provide estimates that are generally accurate within 10-15% for most people. However, individual metabolism can vary due to factors like genetics, muscle mass, hormones, and medical conditions. Use the results as a starting point and adjust based on your actual results over time.

Daily calorie needs vary greatly by individual. Generally, adult women need 1,800-2,400 calories per day, while adult men need 2,200-3,000 calories per day. Your specific needs depend on age, size, activity level, and goals. Use our calculator to get a personalized estimate.

BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic physiological functions like breathing, circulation, and cell production. It typically accounts for 60-75% of your total daily calorie expenditure. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor to account for physical activity.

Yes, calorie calculators are valuable tools for weight management. For weight loss, you need to create a calorie deficit (eat fewer calories than you burn). For weight gain, you need a calorie surplus. A safe rate is typically 0.5-1 kg (1-2 lbs) per week, which requires a deficit or surplus of about 500-1000 calories per day.
