Estimated Energy Requirement Calculator

This Free Estimated Energy Requirement Calculator is a tool similar to TDEE and maintenance calorie calculators and it will tell you how many calories you can eat throughout the day to maintain your current weight. The Calculator quickly calculates the estimated energy requirement needed to maintain the current bodyweight of the individual.

Estimated Energy Requirement Calculator: The EER Calculator can be used by both males and females and all age groups of people. Its value depends on various things such as age, weight, sex, height, physical activity level, and physiological state (i.e illness, pregnancy, lactation). Refer to the below-given module to learn about the estimated energy requirement definition, EER formula, and steps to calculate EER with solved example.

What is EER?

EER is an abbreviation of “Estimated Energy Requirement”. It is the average energy intake that is required to maintain the current weight of the person. This parameter can be used by people of any age group. Estimated Energy Requirement depends on age, gender, weight, height, and level of physical activity.

We can calculate the EER for some special cases like small children or pregnant and lactating ladies, for that one should consider the daily energy required & calorie intake to support a growing body or the lactation of milk at a healthy rate.

How Much Energy Does Your Body Need?

According to US government studies, the average man needs 2,700 kcal per day & the average woman needs 2,200 kcal per day. It shows that different people burn energy at different rates because people have different types of lifestyles than others.

EER Formula | Estimated Energy Requirement Formula

Here, the 1st chart is the EER equations for different age groups. The 2nd chart is the physical activity (PA) coefficient used in EER equations. The 3rd chart is the level of physical activity (PAL).

Here, PAL is used to check the energy required, while PA values are used in the EER equation to estimate the energy levels required for different physical activities.

EER Calculation with Steps

  • Select the formula for calculating EER.
  • Check the weight of a person.
  • Insert gender of a person & age of a person in years.
  • Enter the height of a person in proper measurement systems.
  • Select the level of your physical activity that reflects your lifestyle from the options: very active, active, low active, and sedentary
  • Enter the values in the formula & calculate the final answer.

If you are aiming to do regular calculations use our online collection of calculators from onlinecalculator.guide and calculate.

Solved Example on Estimated Energy Requirement with Formula

Determine the EER of a person who is 30-year-old and has a height of 1.85 meters, weight of 75 kg, and PA of 1.25.

Solution:

For a 30-year-old, the EER formula should be

EER = 662 - (9.53 × Age [yr]) + 1.25 × ((15.91 × Weight [kg]) + (539.6 × Height[m]))

Put height = 1.65m, weight = 75 kg & age = 32 yr in above equation

EER = 662 - (9.53 × 32) + 1.25 × ((15.91 × 75) + (539.6 × 1.65))

= 662 - (304.96) + 1.25 × ((1193.25) + (890.34))

= 2961.52 kcal/day
