Input Parameters
Enter your details to calculate your daily protein requirement.
Protein Intake Guidelines
Recommended Dietary Allowance
0.8 g/kg for adults, based on WHO and USDA guidelines.
Activity Adjustments
Athletes and active individuals may need 1.2-2.0 g/kg for optimal performance.
Protein Sources
Include lean meats, fish, eggs, dairy, legumes, nuts, and seeds in your diet.
Daily Protein Requirement Formula
Daily Protein (g) = Weight (kg) × Activity Factor × Adjustment
Where: Weight = body weight in kg, Activity Factor = 0.8-2.0 based on activity level, Adjustment = factor for age and gender
Sedentary
0.8 g/kg - Little to no exercise
Moderately Active
1.2 g/kg - Regular exercise 3-5 days/week
Extremely Active
2.0 g/kg - Intense training or physical job
Daily Protein Requirement Calculator – Calculate Your Optimal Protein Intake
Protein is essential for muscle repair, immune function, hormone production, and overall health. Our Daily Protein Requirement Calculator helps you determine how much protein you need daily based on your body weight, activity level, age, and gender. Whether you're an athlete, fitness enthusiast, or simply maintaining a healthy diet, this tool provides personalized recommendations to support your nutritional goals.
🔹 What is Daily Protein Requirement?
Daily protein requirement refers to the amount of protein you need to consume each day to maintain good health, support bodily functions, and meet your specific needs based on lifestyle and goals.
The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight for adults. However, this can vary significantly based on factors like physical activity, age, gender, and health conditions.
Athletes, bodybuilders, and individuals engaged in intense physical activities may require 1.2 to 2.0 grams per kilogram to support muscle repair and growth.
🔹 Daily Protein Requirement Formula
The calculator uses the following formula to estimate your daily protein needs:
Daily Protein (g) = Weight (kg) × Activity Factor × Adjustment Where: Weight (kg) = Your body weight in kilograms Activity Factor = Multiplier based on activity level: - Sedentary: 0.8 - Lightly Active: 1.0 - Moderately Active: 1.2 - Very Active: 1.6 - Extremely Active: 2.0 Adjustment = Factor for age and gender: - Older adults (>65 years): 0.9 - Women (<50 years): 0.95 - Others: 1.0

🔹 Example Calculations
Example 1: Sedentary Male, 70 kg, 30 years old
Weight = 70 kg, Activity Factor = 0.8 (sedentary), Age = 30 (no adjustment), Gender = Male
Daily Protein = 70 × 0.8 × 1 = 56 grams
👉 This person needs about 56 grams of protein per day.
Example 2: Very Active Female, 60 kg, 25 years old
Weight = 60 kg, Activity Factor = 1.6 (very active), Age = 25, Gender = Female (5% reduction)
Daily Protein = 60 × 1.6 × 0.95 = 91.2 grams
👉 This active woman needs approximately 91 grams of protein daily.
Example 3: Moderately Active Senior Male, 75 kg, 70 years old
Weight = 75 kg, Activity Factor = 1.2 (moderately active), Age = 70 (10% reduction), Gender = Male
Daily Protein = 75 × 1.2 × 0.9 = 81 grams
👉 This senior needs about 81 grams of protein per day.
