About this site
This calculator provides several useful outputs including the calculated 'Body Mass Index' or BMI. It will also estimate your 'Basal Metabolic Rate' or BMR. Also included is an estimate of your 'Total Energy Expenditure' or TEE which indicates the number of calories needed per day to maintain your current weight.
Several of these NEW calculators may be particularly useful for dieters. Just about every single MAJOR calorie/ energy equation that has been released over the last 90 years is included below. Each calculator has a customized printout option for easy analysis.
: Try each calculator - print out the results - then compare!
Estimated 'Calorie' Calculators
Calorie calc (BMR) Harris-Benedict------------------>
Estimation of total calories needed. MOST widely used equation for calculating basal metabolic rate and total calories.
Updated Harris-Benedict Equation------------------>
Revised Harris-Benedict Equ.
The original Harris Benedict equation was revised in 1984. This updated equation can be used to calculate the basal metabolic rate and total calories.
RESTING Metabolic Rate (RMR)----------------------->
This equation can be used to calculate the RESTING metabolic rate and total calories. Mifflin-St Jeor equation.
Schofield equation (BMR)------------------------------->
Schofield equation (BMR)
This equation was part of the previous government guidelines to formulate RDA's and can be used to calculate the basal metabolic rate and total calories needed.
Institute of Medicine Equation- LATEST EQUATION
Estimation of total calories needed. Widely used equation for calculating basal metabolic rate and total calories.
How much weight do you want to lose
(same units as above)
Current daily activity level
: No regular exercise.
Mild activity level:
Intensive exercise for at least 20 minutes 3 times per week. This may include such things as bicycling, jogging, basketball, swimming, skating, etc. If you do not exercise regularly, but you maintain a busy life style that requires you to walk frequently for long periods, you meet the requirements of this level.
Moderate activity level:
Intensive exercise for at least 30 to 60 minutes 3 to 4 times per week. Any of the activities listed above will qualify.
Heavy or (Labor-intensive) activity level:
Intensive exercise for 60 minutes or greater 3 to 4 times per week (see sample activities above). Labor-intensive occupations also qualify for this level. Labor-intensive occupations include construction work (brick laying, carpentry, general labor, etc), farming, landscape worker or similar occupations.
