Protein is the foundation of a healthy, strong body. It builds and repairs muscles, supports metabolism, boosts recovery, and helps you feel full longer.
But the question many people ask is:
“How much protein do I need each day?”
The Protein Daily Intake Calculator gives you the answer — fast and accurately.
It helps you calculate exactly how many grams of protein you should eat per day to match your body weight, activity level, and fitness goals — whether that’s building muscle, losing fat, or simply staying healthy.
⚙️ How the Protein Daily Intake Calculator Works
The calculator uses evidence-based nutritional formulas to estimate your daily protein requirement.
Your ideal intake depends on these main factors:
- Weight: Heavier individuals require more protein for maintenance and repair.
- Activity Level: The more active you are, the higher your protein needs.
- Fitness Goal: Muscle gain, fat loss, or maintenance all affect your target.
- Age and Gender: Protein requirements can vary slightly with age and sex.
The calculator uses a simple formula:
Daily Protein (grams) = Body Weight (kg) × Protein Factor
The Protein Factor is based on your activity and goals:
| Goal / Activity | Protein Factor (g/kg of body weight) |
|---|---|
| Sedentary (little exercise) | 0.8 – 1.0 |
| Lightly Active | 1.0 – 1.2 |
| Moderate Exercise | 1.2 – 1.6 |
| Muscle Gain / Strength Training | 1.6 – 2.2 |
| Fat Loss / Cutting | 2.0 – 2.4 |
| Endurance Athlete | 1.4 – 1.8 |
Once you select your details, the calculator instantly shows your recommended daily protein intake in grams.
🧭 How to Use the Protein Daily Intake Calculator
Using the calculator is simple and takes less than 30 seconds.
Step-by-step guide:

💡 Tip: For best accuracy, enter your current body weight rather than your target weight.
🍳 Example: Daily Protein Intake Calculation
Let’s take a practical example:
- Weight = 75 kg
- Activity = Moderate Exercise
- Goal = Muscle Gain
Formula:
75 × 1.8 = 135 grams of protein per day
✅ Result: You should consume about 135g of protein daily for muscle growth and maintenance.
🥦 Example Protein Distribution
To hit 135g of protein daily, you can divide it across meals like this:
| Meal | Food | Protein (g) |
|---|---|---|
| Breakfast | 3 eggs + 1 cup Greek yogurt | 30 |
| Snack | Whey protein shake | 25 |
| Lunch | Chicken breast + rice + veggies | 40 |
| Snack | Almonds or cottage cheese | 10 |
| Dinner | Grilled fish + quinoa | 30 |
| Total | — | 135g |
