How to Calculate EER

EER, or estimated energy requirement, is a method to determine how much energy intake your body requires on a daily basis. The formula to find out includes the following variables: sex, height, weight and the amount of physical activity you do. As such, by finding out your EER, you can determine how much activity you need to perform on a daily basis to lose weight, gain weight or maintain your current weight. The formulas in this article use weight in kilograms and height in meters.

Things You'll Need

    • 1

      Between the ages of 0 and 24 months old: Multiply your weight by 89 and subtract that number by 100. Add 20 to that number. Your result is your EER.

      Formula form: EER = (89 * your weight - 100) + 20

    • 2

      Between the ages of 3 and 8: Multiply 61.9 by your age to get variable A. Multiply your weight by 26.7 to get variable B. Multiply your height by 903 to get variable C. Now add variables B and C together and multiply that number by PA, which is the amount of physical activity that you do. (For someone who is not active at all, their PA is 1.00. For someone who is sometimes active, their PA is 1.13. For someone who is very active, their PA is 1.26.) Take that number and add 20 and variable A. Now subtract that number from 88.5 and you will have your EER.

      In formula form: EER= 88.5 - (61.9 * your age) + PA * (26.7 * your weight + 903 * your height) + 20

      Between the ages of 9 and 18: Multiply 61.9 by your age to get variable A. Multiply your weight by 26.7 to get variable B. Multiply your height by 903 to get variable C. Now add variables B and C together and multiply that number by PA, which is the amount of physical activity that you do. (For someone who is not active at all, their PA is 1.00. For someone who is sometimes active, their PA is 1.13. For someone who is very active, their PA is 1.26.) Take that number and add 25 and variable A. Now subtract that number from 88.5 and you will have your EER.

      In formula form: EER = 88.5 - (61.9* your age) + PA * (26.7 * your weight + 903 * your height) + 25

      For 19 years old and above: Multiply 9.53 by your age to get variable A. Multiply 15.91 by your weight to get variable B. Multiply 539.6 by your height to get variable C. Add variables B and C together and then multiply it by PA, which is the amount of physical activity you do. (For someone who is not active at all, their PA is 1.00. For someone who is sometimes active, their PA is 1.11. For someone who is very active, their PA is 1.25.) Take that number and add variable A. Now subtract that number from 662 to get your EER.

      In formula form: EER = 662 - (9.53 * your age) + PA * (15.91* your weight + 539.6 * your height)

      Between the ages of 0 and 24 months old: Multiply your weight by 89 and subtract that number by 100. Add 20 to that number. Your result is your EER.

      Formula form: EER = (89 * your weight - 100) + 20

      Between the ages of 3 and 8: Multiply 30.8 by your age to get variable A. Multiply 10 by your weight to get variable B. Multiply 934 by your height to get variable C. Add variables B and C together and then multiply it by PA, which is the amount of physical activity you do. (For someone who is not active at all, their PA is 1.00. For someone who is sometimes active, their PA is 1.16. For someone who is very active, their PA is 1.31.) Take that number and add 20 and variable A. Now subtract that number from 135.3 to get your EER.

      Formula form: EER = 135.3 - (30.8 * your age) + PA * (10 * your weight + 934 * your height) + 20

      Between the ages of 9 and 18: Multiply 30.8 by your age to get variable A. Multiply 10 by your weight to get variable B. Multiply 934 by your height to get variable C. Add variables B and C together and then multiply it by PA, which is the amount of physical activity you do. (For someone who is not active at all, their PA is 1.00. For someone who is sometimes active, their PA is 1.16. For someone who is very active, their PA is 1.31.) Take that number and add 25 and variable A. Now subtract that number from 135.3 to get your EER.

      Formula form: EER = 135.3 - (30.8 * your age) + PA * (10 * your weight + 934 * your heright)+ 25

      For 19 years old and above: Multiply 6.91 by your age to get variable A. Multiply 9.36 by your weight to get variable B. Multiply 726 by your height to get variable C. Add variables B and C together and then multiply it by PA, which is the amount of physical activity you do. (For someone who is not active at all, their PA is 1.00. For someone who is sometimes active, their PA is 1.12. For someone who is very active, their PA is 1.27.) Take that number and add variable A. Now subtract that number from 354 to get your EER.

      In formula form: EER= 354 - (6.91* your age) + PA * ( 9.36 * your weight + 726 * your height)
