BMR Calculator

BMR Calculator – Understand Your Basal Metabolic Rate

The BMR Calculator helps you estimate your Basal Metabolic Rate (BMR). In simple terms, BMR is the number of calories your body needs each day to perform essential functions. These functions include breathing, blood circulation, temperature regulation, and cell repair while your body is at complete rest.

Even if you remain inactive all day, your body continues to burn calories to stay alive. Because of this, this minimum energy requirement is known as your BMR.

What Does Your BMR Result Mean?

Your BMR result shows how many calories your body needs to function properly without any physical activity.

In other words, it represents the baseline number of calories your body requires each day. However, eating far below your BMR for long periods may slow metabolism. Therefore, BMR should be used as a planning guide rather than a strict calorie limit.

How to Use the BMR Calculator for Weight Management

Once you know your BMR, managing your weight becomes easier and more structured.

For example, you can use your BMR as a starting point to plan daily calorie intake:

  • To maintain weight: Eat close to your TDEE (Total Daily Energy Expenditure)
  • To lose weight: Eat about 300–500 calories below your TDEE
  • To gain weight or muscle: Eat about 300–500 calories above your TDEE

As a result, BMR helps you build a realistic and sustainable nutrition plan.

👉 Use the TDEE Calculator to calculate your full daily calorie needs.

BMR Calculator vs TDEE Calculator – What’s the Difference?

Although BMR and TDEE are closely related, they measure different things.

  • BMR: Calories your body burns at complete rest
  • TDEE: Calories your body burns including daily activity and exercise

Because of this difference, TDEE is calculated by multiplying your BMR by your activity level. For accurate calorie planning, it is always best to calculate TDEE after finding your BMR.

BMR Calculator Formula Used in This Tool

This BMR Calculator uses the Mifflin–St Jeor Equation, which is widely regarded as one of the most accurate methods for estimating Basal Metabolic Rate.

BMR Formula

For Men:
(10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5

For Women:
(10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161

Due to its accuracy, this formula is commonly recommended by nutritionists and fitness professionals.
