BMR Calculator

Estimate your Basal Metabolic Rate (BMR) – the calories your body burns at rest – and calculate your daily calorie requirements for maintenance, weight loss, or weight gain.

Why Calculate Your BMR?

Knowing your BMR helps you plan your diet, manage weight, and improve fitness goals by understanding how many calories your body needs daily.

BMR: kcal/day
Daily Maintenance Calories (TDEE):

Calories for Weight Loss (−500 kcal):
Calories for Mild Loss (−250 kcal):
Calories for Weight Gain (+500 kcal):

How the BMR Calculator Works

Our BMR Calculator uses your age, weight, height, gender, and activity level to estimate your Basal Metabolic Rate. It then calculates Total Daily Energy Expenditure (TDEE) for various goals such as maintenance, weight loss, or weight gain.

Why Use a BMR Calculator?

Understanding your BMR helps you make informed decisions about diet and exercise, track your calorie needs, and plan your nutrition for optimal results.

Frequently Asked Questions about BMR

What is BMR?

BMR (Basal Metabolic Rate) is the number of calories your body needs at rest to maintain basic functions such as breathing, circulation, and cell production.

How do I calculate BMR?

Use our BMR Calculator by entering your age, gender, height, weight, and activity level. It applies standard formulas to estimate your daily caloric needs accurately.

What is TDEE?

TDEE (Total Daily Energy Expenditure) is the total number of calories you burn daily, considering your BMR and physical activity. Our calculator provides TDEE estimates for maintenance, weight loss, and weight gain.

Can I use metric and imperial units?

Yes, the calculator supports both metric (kg/cm) and imperial (lb/in) units for your convenience.

How accurate is this BMR calculator?

The calculator provides a reliable estimate using standard BMR formulas. Individual metabolism varies, so results are approximate and for guidance.
