BMR Calculator

Using the BMR Calculator tool to measure the Basel Metabolic Rate (BMR). Your BMR is the amount of energy you spend when you’re in rest every day. Also, this app maps out your daily calorie needs.

Basal Metabolic Rate is the number of calories required to keep the body restless. BMR is also known as metabolism in your body, so any increase in your metabolic weight, such as exercise, will increase your BMR. Simply enter your height, gender, age, and weight below, to get your BMR. If you have decided your BMR you will start tracking how many calories you need to maintain or lose weight a day.

How To Manually Calculate The BMR

It is important to remember that for Basel Metabolic Rate (BMR) calculations, men and women have different formulae. This is because the men have a higher proportion of lean body weight relative to women. We refer to the Mifflin-St Jeor formula (established in 1990, superseding the Harris-Benedict formula of 1919) for the BMR calculations below. You can use one of the formulae below to measure 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

Daily Required Calories

You can calculate your daily calorie requirement once you’ve worked out your BMR by multiplying your BMR by one of the following activity level factors:

  1. If you are sedentary (little or no exercise)
    Calories Per Day = BMR x 1.2
  2. If you are lightly active (light exercise or sports 1-3 days/week)
    Calories Per Day = BMR x 1.375
  3. If you are moderately active (moderate exercise 3-5 days/week)
    Calories Per Day = BMR x 1.55
  4. If you are very active (hard exercise 6-7 days/week)
    Calories Per Day = BMR x 1.725
  5. If you are super active (very hard exercise and a physical job)
    Calories Per Day = BMR x 1.9

What Is BMR Calculator?

BMR stands for the Basal Metabolic Rate which is the amount of calories that you would eat in a day if you were inactive which lay in bed all day. Our BMR calculator lets you measure not just the amount of calories you burn while inactive, but also a daily calorie figure that takes into account the degree of your lifestyle operation. Together these two estimates give you a representative figure of your daily calorie intake.

It is important to bear in mind that estimates of the Basal Metabolic Rate do not take into account the lean body mass which will naturally have its own impact. For example, very muscular people will receive a statistic that possibly underestimates their calorie needs and people who are very overweight will probably get a number that overestimates their calorie requirements.
