Welcome to DeepAdvices.com, your trusted place for simple health tools. Use our free BMR Calculator to learn how many calories your body burns while resting. This number is called your Basal Metabolic Rate—or BMR. Knowing it helps you plan meals, set fitness goals, and keep a healthy weight.
BMR Calculator
What Is Basal Metabolic Rate?
Your basal metabolism is the energy your body needs to stay alive when you are not moving—just breathing, pumping blood, and keeping warm. A basal metabolic rate calculator (sometimes called a metabolic rate calculator or basal metabolism calculator) measures this daily energy use in calories.

| Activity Level | Description | Multiplier* |
|---|---|---|
| Sedentary | Little or no exercise | 1.2 |
| Light | Light exercise 1–3 days/week | 1.375 |
| Moderate | Exercise 3–5 days/week | 1.55 |
| Active | Hard exercise 6–7 days/week | 1.725 |
| Very Active | Physical job + daily exercise | 1.9 |

How to Calculate My Basal Metabolic Rate
Click the “Start” button on the calculator above. Type in your details and press “Calculate.” Our tool uses the trusted Mifflin-St Jeor equation, the same method used by nutrition experts.
Sample Daily Calorie Needs
| Gender | Weight (kg) | Height (cm) | Age (yrs) |
|---|---|---|---|
| Male | 70 | 175 | 30 |
| Female | 60 | 165 | 30 |
| Male | 80 | 180 | 40 |
| Female | 55 | 160 | 25 |
What to Do After You Know Your BMR
Once you know your BMR, you can figure out your total daily calories by adding your activity level. For example, if you walk or exercise often, you need more calories than someone who sits most of the day.
