EER Calculator
Calculate your Estimated Energy Requirement using Institute of Medicine formulas
Calculate Your EER
Personal Information
Age in years
Activity & Conditions
Typical daily activities plus 30-60 minutes of moderate activity
Your Estimated Energy Requirement
Formula used (male):
EER = 662 - (9.53 × Age) + PA × [(15.91 × Weight) + (539.6 × Height)]
Energy Balance Assessment
Example Calculation
Adult Male Example
Profile: 40-year-old male, 70 kg, 172 cm, low active
PA coefficient: 1.11 (low active male)
Formula: EER = 662 - (9.53 × 40) + 1.11 × [(15.91 × 70) + (539.6 × 1.72)]
Calculation: 662 - 381.2 + 1.11 × [1113.7 + 928.1]
Result: 662 - 381.2 + 1.11 × 2041.8 = 2547 calories/day
Physical Activity Levels
Sedentary
PA = 1.0
Minimal activity beyond daily functions
Low Active
PA = 1.11-1.12
30-60 minutes moderate activity daily
Active
PA = 1.25-1.27
60+ minutes moderate activity daily
Very Active
PA = 1.45-1.48
60+ minutes vigorous activity daily
Additional Energy Needs

- • 1st trimester: +0 kcal
- • 2nd trimester: +340 kcal
- • 3rd trimester: +452 kcal
Lactation
- • 0-6 months: +330 kcal

EER Tips
EER represents calories needed to maintain current weight
Based on Institute of Medicine formulas
Includes adjustments for pregnancy and lactation
Individual needs may vary ±10-20%
Understanding Estimated Energy Requirement (EER)
What is EER?
The Estimated Energy Requirement (EER) is the average dietary energy intake that is needed to maintain energy balance in healthy, normal-weight individuals. It represents the daily calorie intake required to maintain your current weight.
Key Factors
- •Age: Metabolic rate decreases with age
- •Sex: Males typically have higher energy needs
- •Weight: Larger body mass requires more energy
- •Height: Taller individuals have higher needs
- •Physical Activity: More activity increases energy needs
EER vs Other Calculations
EER vs TDEE
EER: Uses standardized formulas from Institute of Medicine
TDEE: Calculates BMR + activity factors + thermic effect
Applications
- •Weight maintenance planning
- •Nutritional assessment
- •Dietary guidelines development
- •Clinical nutrition planning
Medical Disclaimer: EER provides general estimates. Individual energy needs may vary significantly. Consult healthcare providers for personalized nutrition advice, especially for medical conditions, pregnancy, or weight management.
