Enter your age, weight, height, and activity level to know exactly how many calories your body needs every day.
A calorie calculator is a simple online tool that helps estimate how many calories your body needs every day. Calories are the energy your body gets from food. We use this energy to walk, think, breathe, work, sleep, exercise, and perform all body functions. Knowing your daily calorie needs can help you plan your meals and understand your body better. This calculator is easy to use and gives a clear estimate based on your age, gender, weight, height, and daily activity.
Understanding your daily calorie needs is very helpful for many health and lifestyle goals. Even if you are not trying to lose or gain weight, knowing your calorie requirement gives you valuable information about your body. For people who want to stay fit, improve their diet, or plan a healthy lifestyle, this tool can be extremely useful.
This tool uses scientifically accepted formulas to estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). BMR calculates how much energy your body needs at rest. TDEE estimates how many calories you burn based on your activity level. Together, they give a close idea of the number of calories your body needs every day.
BMR is the number of calories your body needs to function while resting. Even if you do nothing all day, your body still needs energy to breathe, pump blood, and maintain body temperature.
TDEE includes all energy used in daily activities such as walking, working, exercising, and other movements. It depends on your lifestyle and activity level.
| Activity Level | Description |
|---|---|
| Sedentary | Little to no exercise |
| Lightly Active | Light exercise 1-3 days a week |
| Moderately Active | Moderate exercise 3-5 days a week |
| Very Active | Hard exercise 6-7 days a week |
| Super Active | Intense activity or physical job |
