Discover your personal daily energy and nutrient needs with RNfinity's Nutrition & BMR/TDEE Calculator. Whether you are tracking calories, planning meals, or optimizing your fitness goals, this free, science-backed tool makes it easy to understand your nutritional intake.
Built on accurate data from the USDA Food Database, our calculator provides detailed insights into calories, macronutrients (protein, carbohydrates, fats), and micronutrients (vitamins and minerals) for hundreds of thousands of foods.
By entering your age, gender, height, weight, and activity level, you can calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) in seconds. Knowing your BMR—the number of calories your body burns at rest—combined with TDEE—the calories burned during daily activities—gives you a clear picture of how much energy you need to maintain, lose, or gain weight.
This personalized approach ensures that every calorie counted aligns with your health and fitness goals. Once your energy needs are calculated, the nutrition calculator allows you to search foods, add them to meals, and track your macros and micros in real time.
