Free, science-based health tools for everyone — no signup, no subscription, no nonsense.
NutriCalc Pro was built with one goal: to give everyone access to accurate, easy-to-use health and nutrition tools — completely free of charge. We believe that understanding your body, your caloric needs, and your nutrition shouldn't require expensive apps, gym memberships, or dietitian appointments.
Whether you're trying to lose weight, build muscle, understand your BMI, or simply eat more mindfully, NutriCalc Pro gives you the data you need in seconds, based on the same scientific formulas used by healthcare professionals worldwide.
Calculate the exact nutritional content of any meal using our 200+ food database from USDA FoodData Central.
Calculate your BMI, BMR, and TDEE. Get a personalised health report including body fat estimate and days to goal.
Distribute your daily calories across meals with customisable macro splits. Supports 5 diet goal presets.
Track intermittent fasting sessions with 5 protocol options including 16:8, 18:6, and 20:4.
All calculations use validated scientific formulas — BMI uses the standard WHO formula, calorie calculations use the Mifflin–St Jeor equation, and nutritional data comes directly from the USDA FoodData Central database.
Your health data stays on your device. We never transmit your personal health information to any server. All data is stored locally in your browser.
NutriCalc Pro is available in 8 languages — English, French, German, Spanish, Italian, Traditional Chinese, Japanese, and Portuguese — with support for both metric and imperial units.
NutriCalc Pro will always be free. The site is supported by non-intrusive display advertising. We never charge for any features, require account creation, or sell user data.
All nutritional data in our Calorie Calculator is sourced from the USDA FoodData Central database — the most comprehensive and scientifically rigorous food nutrition database publicly available.
