Calculate Your BMI, BMR, TDEE & Body Fat

Use our free online fitness calculators to find your Body Mass Index (BMI), Basal Metabolic Rate (BMR), Total Daily Energy Expenditure (TDEE), Body Fat Percentage, and Ideal Weight — powered by scientifically validated formulas.

What is BMI (Body Mass Index)?

BMI is a simple screening tool that measures body fat based on your height and weight. The formula is: BMI = weight (kg) ÷ height² (m²). A healthy BMI range is 18.5–24.9. BMI is used worldwide by doctors, nutritionists, and fitness professionals to assess whether a person is underweight, normal weight, overweight, or obese.

What is BMR (Basal Metabolic Rate)?

BMR represents the number of calories your body burns at rest — just to keep your heart beating, lungs breathing, and organs functioning. NutriBD uses the Mifflin-St Jeor equation, the gold standard recommended by the Academy of Nutrition and Dietetics: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161 (female) / + 5 (male).

What is TDEE (Total Daily Energy Expenditure)?

TDEE is the total number of calories you burn per day, including exercise and daily activity. It's calculated by multiplying your BMR by an activity factor. Knowing your TDEE helps you plan calorie intake for weight loss, maintenance, or muscle gain. Eat below TDEE to lose weight, at TDEE to maintain, or above TDEE to bulk.

How is Body Fat Percentage Calculated?

NutriBD uses the U.S. Navy Body Fat Formula, which estimates body fat percentage from neck, waist, and hip circumference measurements. This method is clinically validated and widely used by military and sports organizations. For men: measurements require neck and waist. For women: neck, waist, and hip measurements are needed.

Frequently Asked Questions

Everything you need to know about NutriBD

Learn how NutriBD combines clinical fitness algorithms, intelligent meal tracking, and Gemini AI coaching to help you reach your goals.

What is NutriBD (NutriBD) and how does it help with fitness tracking?

NutriBD is a free, all-in-one personal fitness, nutrition, and health intelligence platform. Powered by Google Gemini AI, it calculates clinical biometrics (BMI, BMR, TDEE, Body Fat %, WHR, Ideal Weight), tracks meals from a 100+ Bengali & global food database, estimates custom recipes using AI, logs workouts, monitors sleep recovery, and tracks 9-point body circumferences.

How does the AI Recipe Estimator work?

Instead of manually calculating individual ingredients, you can type or describe what you cooked in natural language (e.g., '1 bowl chicken curry made with 200g chicken breast, 1 potato, and 1 tbsp mustard oil, ate half'). Gemini AI automatically extracts the raw ingredients, adjusts for cooking oil absorption, and scales the exact calories and macros to the portion you actually ate.

Is NutriBD free to use?

Yes! NutriBD is 100% free with no paywalls, subscriptions, or credit card requirements. All calculators, AI features, and tracking tools are accessible to everyone.

Can I install NutriBD as an app on my phone?

Absolutely. NutriBD is a Progressive Web App (PWA). You can tap 'Add to Home Screen' in Safari on iOS or Chrome on Android to install it as a standalone app on your device.

How does NutriBD calculate my daily calories and macros?

NutriBD uses the clinically validated Mifflin-St Jeor equation to compute your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) based on your gender, age, height, current weight, and activity level. It then customizes your daily caloric deficit/surplus and protein distribution according to your specific goal.
