🍗 Protein Calculator: Calculate Your Daily Protein Needs Easily
Intro
A Protein Calculator is a valuable tool that helps you determine how much protein you need each day based on your body, lifestyle, and fitness goals. Protein is one of the most important macronutrients, essential for muscle growth, repair, immune function, and energy balance.
This tool is ideal for athletes, bodybuilders, weight-loss seekers, or anyone who wants a healthy and balanced diet. While some people may not get enough protein, others may consume too much without realizing it. A Protein Calculator online removes the guesswork and provides a customized daily protein intake in grams, making it easier to plan meals and achieve your health goals.
Formula / Working
Protein needs are typically calculated based on body weight and activity level. The general formula is: Protein (g/day)=Body Weight (kg)×FactorProtein \, (g/day) = Body \, Weight \, (kg) \times FactorProtein(g/day)=BodyWeight(kg)×Factor
Where the factor depends on your goal:
- Sedentary lifestyle: 0.8 g/kg
- Light activity: 1.0 g/kg
- Moderate exercise: 1.2 – 1.6 g/kg
- Strength training or athletes: 1.6 – 2.2 g/kg
For people tracking calories, protein also provides 4 calories per gram.

Examples
Example 1: Sedentary Lifestyle
- Weight: 70 kg
- Factor: 0.8 g/kg
- Protein = 70 × 0.8 = 56 g/day
✅ Enough for basic health and body maintenance.
Example 2: Weight Loss + Moderate Exercise
- Weight: 65 kg
- Factor: 1.4 g/kg
- Protein = 65 × 1.4 = 91 g/day
✅ Supports fat loss while preserving lean muscle mass.
Example 3: Muscle Building
- Weight: 80 kg
- Factor: 2.0 g/kg
- Protein = 80 × 2.0 = 160 g/day
✅ Helps repair muscles and promote strength gains.
