Calculate your basal metabolic rate (BMR) from your gender, age, height and weight.

It also displays your average basal metabolic rate for that age and gender.

Basal Metabolic Rate (BMR) is the minimum amount of energy required to be consumed even when a person is not doing anything.

Even when you lie down and rest, organs such as the heart and lungs are active and consume energy.

The amount of energy you expend during this time is your basal metabolic rate.

The basal metabolic rate changes with age, peaking at the ages of 15-17 for men and 12-14 for women.

The basal metabolic rate is calculated using the following formula.

Male: BMR = 88.362 + (13.397 x Body weight(kg)) + (4.799 x Height(cm)) - (5.677 x Age(years old))

Female: BMR = 447.593 + (9.247 x Body weight(kg)) + (3.098 x Height(cm)) - (4.330 x Age(years old))

Harris-Benedict equation (improved version)

The average basal metabolic rate by gender and age is calculated with reference to the table below.
