Our free Calorie Calculator helps you estimate how many calories you may need each day based on your age, gender, height, weight, activity level, and fitness goal.
Use this calculator to get an estimate of your Basal Metabolic Rate (BMR), maintenance calories, weight-loss calories, and weight-gain calories.
Note: The results are estimates and individual calorie needs can vary depending on factors such as body composition, health conditions, lifestyle, and daily activity.
What Are Calories?
Calories are a measure of energy. Your body needs energy to perform everyday functions such as breathing, moving, digesting food, maintaining body temperature, and exercising.
The number of calories you need each day depends on several factors, including your age, sex, height, weight, activity level, and goals.
Understanding your estimated calorie needs can help you make more informed decisions about your diet and lifestyle.
How Does the Calorie Calculator Work?
This calculator uses your basic personal information to estimate your daily energy requirements.
It first estimates your Basal Metabolic Rate (BMR) and then adjusts the result according to your activity level.
Your BMR represents the approximate amount of energy your body needs to perform essential functions while at rest.
The calculator then uses an activity multiplier to estimate your approximate daily calorie needs.
What Is BMR?
BMR (Basal Metabolic Rate) is the estimated number of calories your body uses at rest to support essential functions such as breathing, circulation, and maintaining body temperature.
BMR does not represent the total number of calories you burn throughout the day because your daily energy expenditure also includes physical activity and digestion.
Our calculator uses the Mifflin-St Jeor equation to estimate BMR.
What Are Maintenance Calories?
Maintenance calories are the approximate number of calories you may need each day to maintain your current body weight at your current activity level.
If you regularly consume around your maintenance calorie level, your weight may remain relatively stable over time. However, actual results can vary between individuals.
Calories for Weight Loss
Weight loss generally requires a sustained calorie deficit, meaning you consume fewer calories than your body uses over time.
Our calculator provides an estimated calorie target for weight loss based on your estimated maintenance calories.
However, calorie requirements are different for every person. Extremely low-calorie diets may not provide adequate nutrition and should not be followed without appropriate professional guidance.
For sustainable results, focus on a balanced diet, adequate protein, regular physical activity, sufficient sleep, and healthy lifestyle habits.
Calories for Weight Gain
Weight gain generally requires consuming more calories than your body uses over time.
Our calculator provides an estimated calorie target for weight gain based on your estimated maintenance calories.
Choosing nutrient-dense foods such as whole grains, dairy or suitable alternatives, nuts, seeds, legumes, fruits, vegetables, and protein-rich foods can help support a balanced diet.
