Protein Calculator
Calculate your optimal daily protein requirements based on weight, goals, and activity levels.
Auto-fill Goal Profiles
⚙️ Calculator Inputs
Optimal target multiplier of **1.4 g/kg** based on your inputs.
💡 Your target is **75% higher** than the traditional RDA minimum, optimizing muscle health, recovery, and appetite regulation.
⏰ Optimal Meal Distribution Planner
For maximum muscle synthesis, distribute your protein targets evenly rather than eating a giant dinner.
🥗 Global Protein Food Calculator
Combine global high-protein food servings to see how they meet your optimal daily target.

The Protein Calculator helps you determine your optimal daily protein intake based on your body weight, age, activity level, fitness goals, and whether you are trying to lose fat, build muscle, or maintain health.
Protein is an essential macronutrient for repairing tissues, maintaining muscle mass, supporting immune function, and regulating hormones. Evolving sports science and nutrition research suggest that active individuals and older adults benefit from protein intakes significantly higher than the standard Recommended Dietary Allowance (RDA) of 0.8 g/kg/day, which is designed only to prevent deficiency in sedentary adults.
This calculator supports both metric and imperial units. It provides target ranges, spreads protein targets across meals for optimal muscle protein synthesis, and includes an interactive global food tracker to help you visualize how to meet your protein target using real food.
How Does the Protein Calculator Work?
1. Select an Auto-fill Profile — Quick-fill options let you instantly set up the calculator based on common goals.
2. Enter Weight & Target Weight — Input your current body weight in kilograms or pounds. If you are overweight, you can enter an adjusted target weight to prevent overestimating requirements.
3. Select Activity / Goal Multiplier — Choose from sedentary, active, endurance, strength training, or fat loss, or enter a custom g/kg target.
4. Choose Dietary Preference — Toggle between Veg, Non-Veg, or Vegan to customize global high-protein food suggestions.
5. Simulate Meals & Foods — Adjust serving sizes of various global foods to see them count towards your daily target in real-time.
Formula & Calculation Method
Standard Daily Target (Optimal):
Daily Protein (g) = Weight (kg) × Goal Multiplier (g/kg/day)
Pounds to Kilograms Conversion:
Weight (kg) = Weight (lbs) ÷ 2.20462
Goal Multipliers (g/kg/day):
- Sedentary: 0.8 – 1.0 g/kg (minimum health baseline)
- Active: 1.2 – 1.6 g/kg (active lifestyle, light exercise)
- Endurance: 1.4 – 1.7 g/kg (running, cycling, cardio)
- Strength: 1.6 – 2.2 g/kg (muscle hypertrophy, bodybuilding)
- Fat Loss: 1.6 – 2.4 g/kg (calorie deficit while preserving lean mass)
- Older Adults (65+): 1.0 – 1.3 g/kg (combating age-related muscle loss)
Overweight Adjustment:
If body weight is significantly above a healthy range, protein targets are calculated using the adjusted target/goal weight, preventing excessively high targets.
Example Calculation
Example: Active Adult (75 kg), Goal = Active Lifestyle (1.4 g/kg)
- Weight = 75 kg
- Multiplier = 1.4 g/kg
- Daily Protein Target: 75 × 1.4 = 105 grams/day
- *RDA Minimum (0.8 g/kg) comparison: 75 × 0.8 = 60 grams/day. (Optimal target is +45g higher).*
