Mifflin-St. Jeor Calculator
Enter your Age, Gender, Height (Feet & Inches), Weight and select the appropriate Activity Correction Factor and click Calculate to get an estimate of your Total Daily Energy Expenditure.
You can calculate your TDEE manually using the Mifflin-St. Jeor formula.
Mifflin-St. Jeor Formula
For men: BMR = [9.99 x wt (kg} + 6.25 x ht (cm) – 4.92 x age (yrs) + 5)] kcal/day
For women: BMR = [9.99x wt (kg) + 6.25x ht (cm) – 4.92 x age (yrs) – 161] kcal/day
Note: Convert pounds to kilograms by dividing by 2.2; convert inches to centimeters by multiplying by 2.54
The BMR value derived from the prediction equation is then multiplied by the appropriate activity correction factor:
Sedentary (little or no exercise): 1.200
Lightly active (light exercise/sports one to three days per week): 1.375
Moderately active (moderate exercise/sports six to seven days per week): 1.550
Very active (hard exercise/sports six to seven days per week): 1.725
Extra active (very hard exercise/sports and a physical job): 1.900
Note: 1 kg= 2.2 lb; 1 inch = 2.54 cm
