Protein is one of the most essential nutrients your body needs to thrive. It builds muscle, repairs tissues, supports hormones, and keeps you feeling full and energized. But the big question many people have is: “How much protein should I eat every day?”
The Protein Amount Calculator is an easy-to-use tool that helps you determine your optimal daily protein intake based on your weight, activity level, and goals. Whether you want to gain muscle, lose fat, or stay healthy, this calculator gives you an accurate number that matches your personal lifestyle and body type.
No more guessing or following generic diet charts — this tool helps you create a customized nutrition plan tailored to your body’s needs.
⚙️ How the Protein Amount Calculator Works
Your daily protein requirement depends on several factors, including your body weight, activity level, age, and fitness goal. The calculator uses scientifically backed formulas from nutrition research and the World Health Organization (WHO) to give you a precise protein target.
The basic formula used is:
Protein (grams/day) = Weight (kg) × Protein Factor
The Protein Factor changes depending on your goals and lifestyle:
| Goal | Protein Factor (grams per kg of body weight) |
|---|---|
| Sedentary (Minimal activity) | 0.8 – 1.0 g/kg |
| Active (Regular exercise) | 1.2 – 1.6 g/kg |
| Muscle Gain (Strength training) | 1.6 – 2.2 g/kg |
| Fat Loss (Preserve muscle while cutting) | 2.0 – 2.4 g/kg |
| Endurance Athletes | 1.4 – 1.8 g/kg |
The Protein Amount Calculator automatically applies the correct multiplier and provides your daily protein intake goal in grams.

🍗 Example: How to Calculate Your Protein Needs
Let’s look at an example.
- Weight: 75 kg
- Goal: Fat Loss
- Activity Level: Moderate
Using the formula:
75 × 2.2 = 165 grams of protein per day
✅ Result: You should consume approximately 160–170 grams of protein each day to support fat loss while maintaining muscle.
Here’s what that looks like in real food:
| Food | Protein (grams) |
|---|---|
| 2 eggs | 12g |
| 1 chicken breast | 30g |
| 1 cup Greek yogurt | 10g |
| 1 protein shake | 25g |
| 1 cup lentils | 18g |
| 100g fish | 22g |
| Handful of almonds | 6g |
| 1 glass milk | 8g |
| Total: ~131g (Add another shake or serving to hit 160g) |
