What Is Protein Calculator?
A protein calculator is a sophisticated nutritional tool that determines your daily protein requirements based on your body composition, activity level, age, gender, and fitness goals. This professional protein calculator provides comprehensive nutritional analysis to help you optimize your protein intake for health, performance, and body composition goals.
Our online protein calculator uses scientifically validated formulas and research-based recommendations to calculate your personalized protein needs. This free protein calculator tool helps you understand your unique nutritional requirements and plan your meals accordingly for optimal results.
Protein Calculator Formula
The protein calculator uses precise mathematical formulas and nutritional science to determine your daily protein requirements. Understanding these protein calculator formulas helps you appreciate the accuracy of your personalized nutrition recommendations.
Core Protein Calculator Calculations
BMR Calculation (Mifflin-St Jeor Equation)
Male: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5
Female: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161
The protein calculator uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR), which represents the calories your body needs at rest.
TDEE Calculation
TDEE = BMR × Activity Multiplier
Activity Multipliers: Sedentary(1.2), Light(1.375), Moderate(1.55), Active(1.725), Very Active(1.9)
The protein calculator applies activity multipliers to determine your Total Daily Energy Expenditure (TDEE).
Protein Requirement Calculation
Daily Protein = Body Weight(kg) × Protein Multiplier
Protein Multipliers: Weight Loss(2.2g/kg), Maintenance(1.6g/kg), Muscle Gain(1.8g/kg)
The protein calculator determines your protein needs based on your body weight and specific fitness goals.
