Basal Metabolic Rate (BMR)

Your BMR is the amount of energy you expend each day when at rest in a neutrally temperate environment. To get your BMR, simply input your height, gender, age and weight below. Once you’ve determined your BMR, you can begin to monitor how many calories a day you need to maintain or lose weight.Calculate your Basal Metabolic Rate with this BMR calculator.

What is Basal Metabolic Rate Calculator?

The Basal Metabolic Rate Calculator uses a formula known as the Harris-Benedict equation to measures the amount of energy our body spends per day given our activity level and lifestyle.

Equation to Calculate Your BMR

BMR for men

BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5
BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) – (5 × age) + 5

BMR for women

BMR (metric) = (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161

BMR (imperial) = (4.536 × weight in pounds) + (15.88 × height in inches) – (5 × age) – 161

Metabolic age

Basal metabolism rises as a child matures and peaks at around 16 or 17, after this point it typically starts to decrease. A low BMR means you have to eat less calories in order to lose body fat and weight

Metabolism refers to all physical and chemical bodily processes that convert or expend energy. This includes bodily functions such as:

  • Blood circulation
  • Respiration
  • Muscle contraction
  • Waste elimination
  • Brain and nerve functions
  • Body temperature regulation
