How to use the EER Calculator?

The process of the advanced Estimated Energy Requirement calculator is very simple. First, you have to fill up the EER Calculator form.

- Choose Gender

- Enter Age in years.

- Enter height in feet/inches or cm you can choose them in the dropdown.

- Enter your current weight in lbs or kg.

- Select your 1 working day of Physical Activity.

- Click on the "Calculate" button.

The EER Calculator will show your Estimated Energy Requirement for one day in the result section

Estimated Energy Requirement 0 Calories/day

To live a healthy life, there is a minimum requirement of energy to perform all the key activities. This energy requirement has to be balanced. Estimated Energy Requirement (EER) defines the energy you need to maintain this balance.

The important thing is that this energy requirement is not the same for all individuals. If one person of 25 years has a certain EER, it is not mandatory that another person of the same age would have the same EER. The use of a quality calculator is the best way to determine correct EER values. 

What is EER?

EER (Estimated Energy Requirement) is the intake of diet required by an individual to maintain balance. Certain factors play roles in deciding the EER value. These include gender, height, weight, age, and physical activity. 

EER Formula:

The general EER equation is

EER = Total Energy Expenditure + Energy Deposition \textbf{EER = Total Energy Expenditure + Energy Deposition}

How to Calculate EER?

The process of calculating EER is very simple and easy to understand. In the above formula, we can see that the two components involved in the EER formula are Total Energy Expenditure and Energy Deposition.

The value of Total Energy Expenditure varies from one individual to the other on the basis of age, gender, and other factors. It's better to calculate your body fat by body fat calculator before calculating EER. 

EER Example

Calculate the EER of a child who is 2 months old and has a weight of 15 kg.

To start with, consider the formula of EER written above

(89×weight [kg]100)+175(89 \times \text{weight [kg]} - 100) + 175

Let us break down this formula further for a child of 2 months.

(89×weight [kg]100)+56(89 \times \text{weight [kg]} - 100) + 56

the weight is 15kg in this case. Thus, EER is given.

(89×weight [kg]100)+22(89 \times \text{weight [kg]} - 100) + 22

(89×weight [kg]100)+20(89 \times \text{weight [kg]} - 100) + 20

EER formulas table:

Gender Age Formula
boy/Girl 0-3 months EER = 88.561.9×Age+physical activity×(26.7×weight [kg]+903×height [m])+20 88.5 - 61.9 \times \text{Age} + \text{physical activity} \times (26.7 \times \text{weight [kg]} + 903 \times \text{height [m]}) + 20
boy/Girl 4-6 months EER = 135.3(30.8×Age)+physical activity×(10.0×weight [kg])+(934×height [m])+20135.3 - (30.8 \times \text{Age}) + \text{physical activity} \times {(10.0 \times \text{weight [kg]}) + (934 \times \text{height [m]}) } + 20
boy/Girl 7-12 months EER = 88.561.9×Age+physical activity×(26.7×weight [kg]+903×height [m])+2588.5 - 61.9 \times \text{Age} + \text{physical activity} \times (26.7 \times \text{weight [kg]} + 903 \times \text{height [m]}) +25
boy/Girl 13-36 months EER = 135.3(30.8×Age)+physical activity×(10.0×weight [kg])+(934×height [m])+25135.3 - (30.8 \times \text{Age}) + \text{physical activity} \times { (10.0 \times \text{weight [kg]}) + (934 \times \text{height [m]}) } + 25
Boy 3-8 years EER =  662(9.53×(Age))+physical activity×(15.91×weight [kg])+(539.6×height [m])662 - (9.53 \times \text(Age)) + \text{physical activity} \times { (15.91 \times \text{weight [kg]}) + (539.6 \times \text{height [m]}) }
Girls 3-8 years EER = 354(6.91×Age)+physical activity×(9.36×weight [kg])+(726×height [m])354 - (6.91 \times \text{Age}) + \text{physical activity} \times { (9.36 \times \text{weight [kg]}) + (726 \times \text{height [m]}) }
Boy 9-18 years EER = Non-pregnant EER+0\text{Non-pregnant EER}+ 0
Girl 9-18 years EER = Non-pregnant EER+340\text{Non-pregnant EER} + 340
Boy 19 years or above  EER = Non-pregnant EER+452\text{Non-pregnant EER} + 452
Girl 19 years or above EER = Non-pregnant EER+330\text{Non-pregnant EER}+ 330

EER Formuls for Pregnant Women (14-50 years old)

1st trimester EER = Non-pregnant EER+400\text{Non-pregnant EER}+ 400
2nd trimester EER = EER(kcal/day)=Total Energy Expenditure + Energy Deposition \mathrm{EER_{(kcal/day)}} =\textbf{Total Energy Expenditure + Energy Deposition}
3rd trimester EER = EER=(89×Weightkg100)+175 \mathrm{EER} = (89 \times \mathrm{Weight_{kg}} - 100) + 175


0-6 months postpartum EER = EER=((89×15)100)+175 \mathrm{EER} = \big( (89 \times 15) -100 \big) + 175
7-12 months postpartum EER = EER=1410 \mathrm{EER} = 1410

All of these formulas and calculations can be performed very quickly and accurately by our estimated energy requirement calculator.

Physical activity is an important factor

What kind of physical activities do you perform during the course of the day? Some people are not active at all. They do not walk or do any form of exercise. On the other hand, certain people work out regularly to keep themselves in shape. For them, the energy requirement would be more than people who are not very active physically. It depends on the physical tasks you perform during the course of the day.
