Your Free Protein Calculator for Smarter Daily Protein Intake

Protein is the building block of muscle, but figuring out exactly how much you need every day is anything but simple. That is why we built this free protein calculator: to answer the most common question of all — how much protein should I eat daily? Instead of following vague advice to "just eat more protein," our online protein calculator uses your age, gender, weight, height, and activity level to compute a precise protein target in grams. Whether you are planning meals for fat loss or training hard for muscle growth, this daily protein calculator delivers a science-backed number you can actually use — and it is completely free, with no sign-up required.

How the Protein Intake Calculator Works

Our protein intake calculator is built on trusted sports nutrition standards from the International Society of Sports Nutrition (ISSN) and the American College of Sports Medicine (ACSM), alongside WHO/FAO reference intake guidance. It starts by calculating your Basal Metabolic Rate using the Mifflin-St Jeor equation, then applies your activity multiplier to estimate your Total Daily Energy Expenditure. From there, it applies an evidence-based grams-per-kilogram ratio based on your fitness goal, so you receive a recommended target, a healthy range, and your protein calories as a percentage of your daily energy — all calculated for your individual body. A protein calculator for women and a protein calculator for men both start from the same science; your gender only adjusts the starting metabolic estimate so the result fits you personally.

Protein Calculator for Women and Girls

Protein needs do not differ by sex — but the right amount for women and girls still depends on your own body, not a generic average. Our protein calculator for women and the same protein calculator for girls start from your exact weight, age, height, and activity level, so a 60 kg woman training three times a week gets a very different target from a 45 kg girl just starting out. In both cases the recommendation follows the same evidence-based grams per kilogram of body weight — a protein intake calculator for women is not about a separate "female" ratio, it is about calculating your number with accuracy instead of guessing.

Many women ask how much protein to eat to build muscle, lose fat, or simply stay healthy. Using the protein calculator for women, a typical active woman aiming for muscle gain would target about 1.6–2.2 g per kg of body weight per day, while one focusing on maintenance falls in the 1.2–1.8 g range. The calculator also factors in that women's resting metabolism is estimated differently than men's, so supporting numbers like calories and macros are tailored rather than copied from a male default. Enter your details, hit Calculate Protein, and the protein intake calculator for women gives you a target, a healthy range, and a full-day plan built around real foods.

Protein Calculator for Weight Loss

Trying to lose fat without losing muscle? Switch your goal and the protein calculator for weight loss automatically applies a higher protein ratio of up to 2.2 g per kg of body weight. Higher protein during a calorie deficit helps preserve lean mass, keeps you fuller for longer, and supports recovery between workouts. Because targets are calculated from your own body data, this protein calculator for weight loss female and male users alike is accurate to the individual rather than a one-size-fits-all guess. You also get a target range, so you can aim for the sweet spot that protects muscle while you cut.

Protein Calculator for Muscle Gain, Bodybuilding, Cutting and Bulking

Building muscle? Set your goal to muscle gain and the protein calculator for muscle gain recommends 1.6–2.2 g per kg of body weight — the range that research shows maximizes muscle protein synthesis. That same evidence base powers protein intake for bodybuilding, whether you are in a clean bulk or a strict cut. The protein calculator for bulking uses the higher end of the range to fuel growth, while the protein calculator for cutting keeps the ratio high so you hold onto hard-earned muscle while dropping fat. Every number is tailored to your height, age, and activity level for the best possible results.

How Much Protein for Your Body Weight?

Wondering about a specific weight? An adult using the protein calculator 70 kg target typically needs roughly 112–154 g daily for muscle gain, while a protein calculator 60 kg user targets around 96–132 g on the same plan. At the upper end, the answer to how much protein for 80 kg is usually 128–176 g per day. These are only starting points — your exact target depends on age, gender, and activity level, which is exactly what this calculator computes for you in seconds.

Protein Calculator in Food: Turn Your Target into a Plate

Knowing your number is only half the battle — you also need to know where your protein comes from. That is why this daily protein calculator includes an interactive high protein foods page. Search across animal and plant sources, from chicken breast and whey isolate to tofu and lentils, and see protein grams, calories, leucine content, and quality ratings for every serving. The plate builder totals your selections against your goal with a live progress bar, so you always know how much protein in food you still need before the day ends.

Build My Protein Day: A Full-Day Meal Plan from Your Target

Turning a number into actual meals is the hardest part — so this protein day plan builder does it for you. Hit "Build My Day" and the calculator arranges a complete high protein meal plan for the day across breakfast, lunch, snack, and dinner using real foods from the high protein foods page. Each meal shows exact portions and protein grams, with a running total against your target. Whether you want a vegetarian protein day plan built from tofu, lentils, and chickpeas or a meat-based plan with chicken and salmon, the builder gives you a workable starting point you can swap and adjust.

More Than Just a Daily Protein Intake Calculator

Beyond the headline number, this female protein intake calculator and male-focused tool delivers a complete nutrition dashboard: BMR calories, total daily energy expenditure, BMI, a daily water target, and four macronutrient presets. Results are easy to share — copy a link with your exact settings or save a printable report. Start tracking with the daily protein log to record what you eat, monitor your 7-day and 30-day trends, and build a consistency streak.

Whether you are a beginner or a competitive athlete, using a daily protein intake calculator tailored to your body is one of the smartest steps you can take toward hitting your fitness goals. Try the protein intake calculator for muscle gain, for weight loss, or for simple maintenance above — and start making every meal count. Pairing a solid protein target with a consistent daily creatine dose is a common way to support muscle growth — use our creatine calculator to find your recommended dose by weight.
