# BMR Calculator

Calculate your Basal Metabolic Rate (BMR) with this calculator tool. Your BMR is the amount of energy you expend each day when at rest. Gender, age, height and weight are important for this calculation.
All fields are mandatory.
 Gender: Female Male Age: Your Height: Feet:      Inches: Weight (pounds): Select your activity level: I am sedentary (little or no exercise)   I am lightly active (light exercise or sports 1-3 days per week)   I am moderately active (moderate exercise or sports 3-5 days per week)   I am very active (hard exercise or sports 6-7 days per week)   I am super active (very hard exercise or sports and a physical job or 2x training) Confirm you are not a robot! 9 x 5 =

The results given by this BMR calculator should be used only as a guide and should not replace medical advice. Please bear in mind that, when interpreting the results of this BMR calculator, other factors such as your lean body mass should be considered. More information on that is available below.
This calculator uses the Harris-Benedict equation to calculate figures.
You should always speak to a qualified Doctor or health professional for advice and guidance before making any dramatic changes to your lifestyle.

### What is BMR?

BMR stands for basal metabolic rate and represents the number of calories you would burn in a day if you were inactive and stayed in bed all day. Our BMR calculator allows you to calculate not only the number of calories you burn when inactive but also a daily calorie figure that takes into account your lifestyle activity level. These two figures together give you a representative figure for your daily calorie intake. The BMR tool uses two formulas to calculate figures:

• ###### Basal Metabolic Rate (BMR)

This formula takes basic variables such as your age, weight and height and provides you with the number of calories you might burn each day if you were inactive for that day.

• ###### Harris Benedict Formula

We use the original Harris Benedict Formula to calculate your daily calorie burn based upon your activity level. The calculation is fairly straight forward, taking your BMR and multiplying it by a set figure based on how active you are.

Using these equations, our calculator can provide you with an accurate gauge of your daily calorie burn. Do bear in mind that the one thing this method omits is lean body mass, which will obviously have a factor of its own. Very muscular people, for example, with receive a figure that probably under-estimates their calorie needs and very overweight people will get a calculation that over-estimates their calorie requirements.
