Calorie Calculator
Estimate your daily calorie needs for weight management and health goals.
What Are Calories and Why Do They Matter?
A calorie is a unit of energy. In nutrition, calories refer to the energy people get from the food and drink they consume, and the energy they use in physical activity. Understanding your calorie needs is the cornerstone of effective weight management and achieving your fitness goals. Your body requires a certain amount of energy just to perform its basic, life-sustaining functions like breathing, circulating blood, and cell production. This is known as your Basal Metabolic Rate (BMR). When you factor in your daily activities, the total amount of energy you burn is called your Total Daily Energy Expenditure (TDEE). This calculator helps you estimate both.
Understanding Your Results: BMR vs. TDEE
Basal Metabolic Rate (BMR)
Your BMR is the number of calories your body needs to function at rest. It accounts for the energy used by your vital organs, which makes up a significant portion of your daily energy use. This calculator uses the widely-accepted Mifflin-St Jeor equation to estimate your BMR, which is considered more accurate than older formulas.
Total Daily Energy Expenditure (TDEE)
Your TDEE, or maintenance calories, is your BMR plus the calories you burn through physical activity. This is the total number of calories you need to consume each day to maintain your current weight. Our calculator multiplies your BMR by an activity factor (from sedentary to extra active) to estimate your TDEE. This is the most important number for setting your weight goals.
How to Set Your Calorie Goals
Once you know your TDEE (maintenance calories), you can set goals for weight management based on the principle of energy balance.
- For Weight Loss: To lose weight, you need to be in a calorie deficit, meaning you consume fewer calories than your TDEE. A safe and sustainable deficit is typically 300-500 calories per day, which leads to a loss of about 0.5-1 lb per week. Our calculator provides targets for “Mild” and “Standard” weight loss to guide you.
- For Weight Maintenance: To maintain your current weight, simply aim to eat your TDEE (maintenance) calories each day.
- For Weight Gain: To gain weight, primarily muscle, you need to be in a calorie surplus. Consuming 300-500 calories more than your TDEE, combined with regular resistance training, is an effective strategy for lean muscle gain.
Frequently Asked Questions (FAQ)
How accurate is this calorie calculator?
This calculator provides a very good estimate based on the proven Mifflin-St Jeor formula. However, it’s an estimation. Individual factors like genetics, body composition (muscle vs. fat), and hormones can influence your exact calorie needs. Use this result as a starting point and adjust based on your real-world progress.
Why do men and women have different calorie formulas?
On average, men have a higher muscle mass and lower body fat percentage than women of the same size and weight. Since muscle tissue burns more calories at rest than fat tissue, their BMR is typically higher. The formulas are adjusted to account for these general physiological differences.
Should I eat the same number of calories every day?
Not necessarily. While your weekly average is most important for weight management, many people find success with “calorie cycling,” where they eat more on workout days and slightly less on rest days. The key is to ensure your average daily intake over the week aligns with your goal.

What is a Calorie Calculator?
A calorie calculator is a tool that helps you estimate the number of calories you need to consume daily to achieve your goals. These calculations are based on your Basal Metabolic Rate (BMR) and your level of physical activity. BMR is the number of calories your body needs to function at rest—just to keep your heart beating, lungs breathing, and cells functioning. By combining this with your activity level, the calculator gives you a personalized estimate of your Total Daily Energy Expenditure (TDEE)—the total number of calories you burn in a day.
The Calorie Calculator featured here is designed to be user-friendly, allowing you to enter your data and get results in a matter of seconds. Plus, with options for both US and Metric units, it’s adaptable to users worldwide.
Why Use a Calorie Calculator?
Understanding how many calories your body needs is essential for several reasons:
- Weight Management: Whether you want to lose, gain, or maintain your weight, knowing your daily caloric needs allows you to create a proper meal plan.
- Health and Fitness: By understanding your calorie needs, you can fuel your body properly to support workouts, muscle recovery, and overall health.
- Avoid Overeating: Monitoring your caloric intake can help prevent overeating, which often leads to unwanted weight gain or health issues.
- Optimized Nutrition: Using a calorie calculator can help you make more informed food choices, ensuring you get the right amount of calories and nutrients for your lifestyle.
How Does the Calorie Calculator Work?
This Calorie Calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR). This equation takes into account your age, gender, height, and weight to calculate the number of calories you would burn if you did nothing all day. Then, depending on your activity level, the tool multiplies your BMR by an activity factor to estimate your Total Daily Energy Expenditure (TDEE).
Here’s the equation used:
For men:
BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5
For women:
BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161
Once your BMR is calculated, it is multiplied by an activity multiplier based on how active you are. This gives you an estimate of how many calories you need each day, depending on whether you’re sedentary, lightly active, moderately active, or very active.
Step-by-Step Guide to Using the Calorie Calculator
Follow these simple steps to use the Calorie Calculator and find out how many calories you need daily:
- Choose Your Units (US or Metric)
At the top of the calculator, you will see two buttons: one for US units (feet, inches, pounds) and one for Metric units (centimeters, kilograms). Choose the unit system you prefer by clicking the appropriate button.
US Units: You’ll need to enter your height in feet and inches, and your weight in pounds.
Metric Units: Enter your height in centimeters and weight in kilograms.
The default unit is set to US, but you can easily switch to Metric by clicking the corresponding button.
- Enter Your Age
The age field accepts numbers between 15 and 80. Simply type in your age and make sure it falls within this range. Your age is an important factor in determining your metabolic rate, as metabolic function tends to decrease as we age.
- Select Your Gender
Next, you’ll select your gender. This is important because men and women have different metabolic rates. Choose between “Male” and “Female” from the dropdown menu.
- Enter Your Height
Your height plays a crucial role in determining how many calories you need. Depending on the unit system you’ve selected:
For US Units: Enter your height in feet and inches. There are separate fields for both.
For Metric Units: Enter your height in centimeters.
- Enter Your Weight
Your weight also has a significant impact on your BMR. Based on the unit system you’ve selected:
For US Units: Enter your weight in pounds (lbs).
For Metric Units: Enter your weight in kilograms (kg).
- Select Your Activity Level
The activity level section allows you to specify how physically active you are on a regular basis. Choose the option that best matches your lifestyle:
Basal Metabolic Rate (BMR): For the number of calories you burn at rest.
Sedentary: Little to no exercise, mostly desk work.
Light: Light exercise 1-3 days a week.
Moderate: Moderate exercise 3-5 days a week.
Active: Daily exercise or intense workouts 3-4 days a week.
Very Active: Intense exercise 6-7 days a week.
Extra Active: Very intense exercise or a physically demanding job.
Your TDEE will be higher if you are more active, meaning you will need more calories to maintain your weight.
- Click “Calculate”
Once all your data is entered, click the Calculate button to get your results. The calculator will display your daily calorie needs, which is an estimate of how many calories you should consume each day to maintain your current weight.
How to Interpret Your Results
The number you get from the Calorie Calculator is an estimate of how many calories you need each day based on your current lifestyle. Here’s how you can use that number:
