Our BMR Calculator is a free online health tool that helps you calculate your Basal Metabolic Rate (BMR) quickly and accurately. By entering your age, gender, height, and weight, you can estimate the number of calories your body burns each day while at complete rest. Whether your goal is weight loss, weight maintenance, muscle gain, or improving your overall fitness, our BMR Calculator provides a reliable starting point for planning your daily calorie intake.
Basal Metabolic Rate (BMR) represents the minimum amount of energy your body requires to perform essential life-sustaining functions such as breathing, blood circulation, body temperature regulation, and cell production. Knowing your BMR helps you understand how many calories your body needs before considering physical activity or exercise.
What is a BMR Calculator?
A BMR Calculator is an online tool that estimates your Basal Metabolic Rate using scientifically accepted formulas such as the Mifflin-St Jeor Equation. It calculates the number of calories your body burns while at rest and serves as the foundation for estimating your Total Daily Energy Expenditure (TDEE).
How Does a BMR Calculator Work?
Enter your gender, age, height, and weight into the calculator. After clicking the Calculate button, the tool applies the Mifflin-St Jeor formula to estimate your BMR. It may also calculate your estimated daily calorie requirements based on different activity levels, helping you determine how many calories you need to maintain, lose, or gain weight.

Why Calculate Your BMR?
Knowing your BMR helps you understand the minimum number of calories your body needs each day to function properly. When combined with your activity level, it allows you to estimate your Total Daily Energy Expenditure (TDEE), making it easier to set realistic calorie goals for losing fat, maintaining weight, or building muscle.
Tips for Improving Your Metabolism
- Exercise regularly with a combination of strength and cardio training.
- Consume enough protein to support muscle maintenance.
- Stay hydrated throughout the day.

Frequently Asked Questions
What is Basal Metabolic Rate (BMR)?
Basal Metabolic Rate is the number of calories your body burns each day while performing essential functions such as breathing, blood circulation, and maintaining body temperature.
Is this BMR Calculator free?
Yes. Our BMR Calculator is completely free and can be used as many times as you need.
What formula does this calculator use?
Our calculator uses the widely accepted Mifflin-St Jeor Equation, which provides a reliable estimate of Basal Metabolic Rate for most adults.
What is the difference between BMR and TDEE?
BMR is the number of calories your body needs at complete rest, while TDEE (Total Daily Energy Expenditure) includes the calories burned through physical activity and daily movement.
Can I use my BMR to lose weight?
Yes. Knowing your BMR and estimated daily calorie needs can help you create an appropriate calorie deficit for weight loss or a calorie surplus for muscle gain while supporting your overall health.
