How Calorie Calculator Works?

Calculate your daily calorie needs based on your age, weight, height, gender, and activity level.

1

Enter your weight, height, age, gender, and activity level.

2

Your Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor equation.

3

BMR is multiplied by your activity level factor to get your maintenance calories.

4

A 500-calorie deficit is subtracted for the weight loss target, and 500 calories are added for weight gain.

5

Results show your BMR, maintenance calories, and calorie targets for weight loss and gain.

Formula Used

Men: BMR = 10 x weight(kg) + 6.25 x height(cm) - 5 x age - 5 | Women: BMR = 10 x weight(kg) + 6.25 x height(cm) - 5 x age - 161 | Maintenance = BMR x Activity Multiplier

These are estimates based on averages. Individual calorie needs vary based on metabolism, body composition, and health conditions.

Important — Read Before You Decide

  • Calorie calculators provide estimates — individual needs vary
  • Crash diets below 1200 cal/day can be dangerous
  • Quality of calories matters as much as quantity
  • Consult a doctor before starting extreme calorie restriction
  • Metabolism slows with age, requiring gradual adjustments

What Happens If You Ignore These?

  • Chronic overeating leads to obesity and related diseases
  • Severe undereating causes muscle loss and nutrient deficiencies
  • Yo-yo dieting damages metabolism over time
  • Ignoring nutrition quality leads to hidden health problems

Smart Tips

  • A 500 calorie deficit per day leads to ~0.5 kg weight loss per week
  • Eat protein with every meal to maintain muscle mass
  • Drink water before meals — thirst is often mistaken for hunger
  • Track your food intake for at least 1 week to understand patterns
