Whether your goal is to gain muscle, lose fat, or maintain your current physique, this calculator provides a personalized protein target backed by scientific research.

Protein plays an essential role in muscle recovery, metabolism, hormone production, and overall health.

How to Use the Protein Amount Calculator

Using the Protein Amount Calculator is simple and user-friendly. Follow these steps to calculate your personalized protein needs:

1. Enter Your Weight
   • Input your current body weight in either kilograms (kg) or pounds (lb).
   • The tool accepts values between 20 and 400.
2. Select Your Sex
   • Choose either “Male” or “Female.”
   • This helps adjust recommendations slightly for biological differences in metabolism and muscle mass.
3. Enter Your Age
   • Input your age (between 12 and 100 years).
   • Protein needs tend to increase slightly with age due to muscle preservation requirements.
4. Choose Your Activity Level
   • Options range from Sedentary (little to no exercise) to Athlete (heavy training).
   • The more physically active you are, the more protein your body requires for muscle repair and recovery.
5. Select Your Goal
   • Choose from three main goals:
     • Maintain Weight/Health – for general wellness or stable weight.
     • Lose Weight (Fat Loss) – higher protein intake helps preserve lean muscle during caloric deficits.
     • Gain Muscle – increased protein supports muscle growth and recovery after resistance training.
6. Click “Calculate”
   • The tool will display a loading bar labeled “Calculating your protein needs…”
   • Within seconds, your personalized daily protein recommendation will appear.
7. View Your Results
   • You’ll see:
     • Recommended Protein (grams)
     • Protein Range (grams)
     • Per kg Body Weight (g/kg)
     • Per lb Body Weight (g/lb)
8. Copy or Share Your Results
   • Use the “Copy Results” button to save your numbers for later.
   • Click “Share Results” to post your recommendation on social media or send it to a friend.

Practical Example

Let’s say Maria, a 35-year-old woman who weighs 65 kg (143 lb), exercises moderately (3–5 days per week), and wants to lose fat.

Here’s how her calculation might look:

• Weight: 65 kg
• Activity Level: Moderate
• Goal: Fat loss

Based on the calculator’s algorithm, Maria’s protein range would be approximately 117 g – 176 g of protein per day, with an average recommendation of around 146 g.

This means Maria should aim to consume roughly 145 grams of protein daily to support fat loss while maintaining lean muscle mass.
