How to Use the Calculator

The BMR & TDEE calculator can be used to get an accurate estimate of your Base Metabolic Rate and Total Daily Energy Expenditure.  Fill in the fields above with your information.  If you know your Body Fat %, enter it into the appropriate field above, as it will increase the accuracy of the calculator.  If you do not know your Body Fat %, then leave that field blank.  Click "Calculate" and that's it!


Base Metabolic Rate (BMR) is the measure of how many calories your body burns in a day before any exercise or activity is taken into account.  If you lay in bed all day, your body still burns calories to perform basic functions such as maintaining body temperature, breathing, digestion, etc.


Total Daily Energy Expenditure is the measure of how many total calories total your body burns in a day.  TDEE takes into account BMR plus the calories burned during exercise and daily activities.  To calculate TDEE, you will need to estimate your activity level.

TDEE and Weight Loss

Inspite of all the dietary hype we hear each day, weight loss remains a very simple concept:  to lose weight, you must burn more calories than you consume.  Your TDEE is an estimate of how many calories you burn in a day.  To lose weight, choose a target number of calories to consume each day that is less than your TDEE and consistently hit your target.


This BMR & TDEE calculator does not provide medical advice and is for information purposes only.  You should always consult your Doctor before starting a new diet or exercise program.
