This BMR Calculator (BMR stands for Basal Metabolic Rate) takes your age, gender, height, and weight as inputs to estimate your per day Basal Metabolic Rate or BMR. BMR indicates the calorie spent every day when your body rests in a pleasant environment. The BMR Calculator uses the Mifflin – St Jeor’s equation of measuring Basal Metabolic Rate.


Your current age rounding to the nearest year.


Mention whether you are male or female. The equation of Mifflin – St Jeor calculates the BMR for male and female.


Mention your height in this field. Use the US Units if you prefer feet and inches to measure your height.

What is Basal Metabolic Rate (BMR)?

The required amount of calorie or energy to run your vital body parts when your body is resting in a pleasant environment after the absorptive state is known as Basal Metabolic Rate or BMR. BMR is the energy required when the digestive system is not in action. So, where will the energy be used if the digestive system is inactive? Yes, they will be used only to run your vital organs like heart, liver, kidneys, lungs, muscles, intestines, nervous system, sex organs, and skin.

The Mifflin – St Jeor equation of BMR

10 * weight(kg) + 6.25 * height(cm) – 5 * age(y) + 5
10 * weight(kg) + 6.25 * height(cm) – 5 * age(y) – 161
