BMR Calculator

The BMR Calculator estimates your Basal Metabolic Rate using your age, gender, weight, and height. BMR is the approximate amount of energy your body uses at rest to support essential functions such as breathing, circulation, and maintaining body temperature.

How to Use the BMR Calculator

1. Select the gender option requested by the calculator.
2. Enter your age in years.
3. Enter your weight in kilograms and height in centimeters.
4. Click Calculate BMR to view your estimate and the displayed activity-level calorie values.

What Is Basal Metabolic Rate?

Basal Metabolic Rate (BMR) estimates the energy your body needs at rest. It is different from your total daily energy expenditure, which also includes physical activity and the energy used to digest food.

BMR and Daily Calorie Needs

Your daily energy needs are generally higher than your BMR because you move, exercise, and carry out everyday activities. The activity-level estimates shown by this calculator can help provide additional context, but they are estimates rather than exact measurements of your individual needs.

Use this free BMR Calculator as an informational tool, not as a medical diagnosis or a personalized nutrition plan. Individual calorie needs can vary with health, body composition, and other factors. Consult a qualified healthcare professional for personalized guidance.
