Calorie Calculator
About This Calorie Calculator
Our Calorie Calculator helps you determine how many calories you need per day based on your age, gender, height, weight, and activity level. Whether your goal is weight loss, weight gain, or weight maintenance, this tool gives an accurate daily calorie estimate.
Calories are units of energy your body needs to perform daily functions such as breathing, digestion, walking, and exercise. Eating too many calories leads to weight gain, while eating fewer calories helps in weight loss.
This calculator uses the Mifflin-St Jeor equation, one of the most accurate formulas to calculate Basal Metabolic Rate (BMR). It then multiplies BMR with your activity level to determine total daily energy expenditure (TDEE).
If your goal is weight loss, the calculator subtracts 500 calories per day. For weight gain, it adds 500 calories. This is a commonly recommended safe range for gradual and healthy weight change.
Maintaining the correct calorie intake helps reduce the risk of obesity, heart disease, diabetes, and other lifestyle-related health issues.
This tool is free, mobile-friendly, and easy to use.
