What is the Vegan Protein Calculator?
This calculator uses scientifically-backed formulas to determine your personalized protein requirements based on a vegan diet. Unlike conventional protein calculators, ours takes into account the specific needs of plant-based eaters, considering protein digestibility and amino acid profiles.

The Science Behind Vegan Protein Requirements
Basic Protein Calculation Formula
Protein Required (g) = Body Weight (kg) × Protein Factor
Sedentary
0.8 g/kg
Moderately Active
1.0-1.2 g/kg
Very Active
1.4-1.8 g/kg
Vegan Protein Adjustments
Plant proteins generally have lower digestibility and different amino acid profiles compared to animal proteins. Our calculator applies the following adjustments:
Digestibility Adjustment
Plant proteins have a digestibility of ~80-90% compared to animal proteins. We adjust by applying a factor of 1.1 to account for this difference.
Amino Acid Completeness
To ensure adequate intake of all essential amino acids, our calculator recommends a diverse range of plant protein sources for optimal nutrient absorption.
Goal-Specific Adjustments
Weight Loss
+10-15% increase
Maintenance
Standard calculation
Muscle Gain
+20-30% increase
Special Considerations
Age & Gender
Older adults (65+) may need slightly more protein (+10%) to prevent age-related muscle loss. Gender-specific adjustments are applied based on body composition differences.
Pregnancy & Nursing
Pregnant individuals require an additional 20-25g protein per day, while those who are nursing need approximately 20g extra per day.
