BMR is short for Basal Metabolic Rate and represent the amount of calories your muscles burn every day just to maintain vital operations such as breathing or thinking. In other words, BMR rate is the amount of calories your body would burn if you were to stay in bed the whole day and do nothing at all!
Please select either metric BMR calculator (EU) or imperial BMR calculator (US).
Note: If entering height in foot and inches please only use 2 digits. Example: height of 6 foot and 1.5 inches should be entered as 6 foot 2 inches.

Please note: BMR calculator will calculate your basal metabolic rate. This is not your total daily calorie expenditure! If you want to know more about BMR read this article on what is basal metabolic rate.
If you have selected activity level when calculating BMR than the above tool will calculate your approximate daily calorie expenditure. If you exceed that number (caloric surplus) you will start to gain weight as your body will gain extra fat. If you do not exceed that number (caloric deficit) you will maintain or lose weight (if caloric deficit is high).

The results provided by our BMR calculator are not 100% accurate as BMR calculator does not take into account the following factors:
The accuracy of this calculation is still fairly accurate for non-obese and non-athlete person.
In order to calculate your Basal Metabolic Rate (BMR), please input your physical characteristics. You can use metric (kilograms, centimeters) or imperial (lbs, inches) BMR calculator. When entering values, do not add “cm” “kg” “lbs” or “ft” to your number, but only input plain numbers. Select your gender (man / woman) and select your activity level. By selecting activity level your calculated value will be moderately higher. This is normal.
