Daily Protein Calculator — How Much Protein to Eat

The daily protein calculator helps you estimate how much protein you need each day. Enter your body weight, choose a goal (maintenance, cutting or muscle building) and activity level — the calculator returns the recommended protein range and an approximate portion per meal. Useful for planning your diet and macros.

How the calculator estimates protein needs

g/kg range by goal: Maintenance = 1.2–1.6 g/kg Cutting = 1.6–2.2 g/kg Muscle building = 1.6–2.0 g/kg Activity adjustment: Low × 0.9 / Medium × 1.0 / High × 1.1 Min protein = weight × lower range × adjustment Max protein = weight × upper range × adjustment Per meal = max protein / 4

Example: 75 kg, maintenance, medium activity

A 75 kg person, maintenance goal, medium activity: range 1.2–1.6 g/kg

minimum protein 75 × 1.2 = 90 g, maximum 75 × 1.6 = 120 g. With 4 meals that is about 30 g of protein per meal.

Frequently asked questions

How much protein should I eat per day?

Protein needs depend on body weight, goal and activity level. For maintenance, 1.2–1.6 g/kg is recommended. For cutting it rises to 1.6–2.2 g/kg, and for muscle building to 1.6–2.0 g/kg. For a 75 kg person at maintenance that is about 90–120 g per day.

Why do I need more protein when cutting?

During a calorie deficit the body tends to lose muscle mass. Higher protein intake (1.6–2.2 g/kg) protects muscle, increases satiety and has a higher thermic effect. That is why higher protein intake is recommended when losing weight.

Is too much protein harmful?

For healthy people, intake up to about 2.0–2.2 g/kg is considered safe. Very high intake (over 3 g/kg) brings no added benefit and may burden the kidneys in people with kidney disease. Those with kidney problems should consult a doctor about protein intake.

How much protein per meal?

Spread daily protein across 3–5 meals of about 20–40 g each. The calculator assumes 4 meals and divides the upper value. For a 75 kg person at maintenance that is about 30 g of protein per meal.

What are good sources of protein?

Rich sources include: chicken breast (31 g/100 g), beef (26 g), fish (20–25 g), eggs (6 g/egg), cottage cheese (18 g), legumes (8–9 g/100 g) and tofu (8 g). Combining animal and plant sources provides a full amino acid profile.

Can vegetarians meet their protein needs?

Yes. Plant-based diets can fully cover needs with legumes, tofu, tempeh, seitan and quinoa. Plant proteins have lower digestibility, so vegans are advised about 10% higher intake and varied sources.
