    What is BMR Calculator?

    BMR Calculator is a free online health and fitness tool that helps you calculate your basal metabolic rate and daily calorie needs. This tool provides instant, accurate results with detailed breakdowns and visual charts to help you understand the numbers behind the calculation.

    Formula Used

    The BMR Calculator uses the following formula: Mifflin-St Jeor Equation: For men: BMR = 10W + 6.25H - 5A + 5. For women: BMR = 10W + 6.25H - 5A - 161, where W is weight in kg, H is height in cm, and A is age in years. TDEE = BMR × Activity Multiplier. The calculation is performed automatically when you click the Calculate button, ensuring error-free results every time.

    How to Use This Calculator

    Follow these steps to use the BMR Calculator: 1. Enter the weight in the provided input field (e.g., 70). 2. Enter the weight unit in the provided input field. 3. Enter the height in the provided input field (e.g., 175). 4. Enter the height unit in the provided input field. 5. Enter the age in the provided input field (e.g., 30). 6. Enter the gender in the provided input field. 7. Click the "Calculate" button to compute your results. 8. Review the detailed results, including charts and breakdowns. 9. Use the "Reset" button to clear all fields and start a new calculation. 10. Try the "Load Example" button to see a sample calculation with predefined values.

    Example Calculation

    Here is a practical example to help you understand how the BMR Calculator works: Example inputs: Weight: 70, Weight Unit: kg, Height: 175, Height Unit: cm, Age: 30, Gender: male Enter these values into the calculator (or click "Load Example Values") to see how the formula produces accurate results. This example represents a typical use case and demonstrates the calculator's output format, including any charts or breakdowns.

    Frequently Asked Questions

    What is BMR?

    Basal Metabolic Rate is the minimum calories your body needs for basic life functions at rest.

    What is TDEE?

    Total Daily Energy Expenditure is BMR plus calories burned through activity and digestion.

    What factors affect my BMR?

    Age, gender, weight, height, muscle mass, and genetics all influence BMR. Muscle mass increases BMR, while aging decreases it.

    What is the Mifflin-St Jeor equation?

    It is the most accurate BMR formula: For men, BMR = 10W + 6.25H - 5A + 5. For women, BMR = 10W + 6.25H - 5A - 161.

    Does exercise increase BMR permanently?

    Exercise builds muscle, which raises BMR long-term. The calorie burn from the workout itself is temporary, but muscle mass provides lasting increases.

    How does age affect BMR?

    BMR decreases by about 1-2% per decade after age 20, primarily due to muscle loss. Strength training can help offset this decline.

    Can I use BMR to plan weight loss?

    Yes, eating below your TDEE (not BMR) creates a calorie deficit. Never eat below your BMR as it can slow metabolism and cause health issues.

    Why do men typically have higher BMR than women?

    Men generally have more muscle mass and less body fat than women of the same weight, and muscle tissue burns more calories at rest.
