The BMR (Basal Metabolic Rate) Calculator estimates the number of calories your body needs to maintain basic physiological functions at rest, such as breathing and digestion. It uses your weight in kilograms, height in centimeters, age, and gender to compute the result.
- For Men: BMR = 10 × Weight (kg) + 6.25 × Height (cm) – 5 × Age (years) + 5
- For Women: BMR = 10 × Weight (kg) + 6.25 × Height (cm) – 5 × Age (years) – 161
- Total Daily Energy Expenditure (TDEE) = BMR × Activity Factor • Sedentary (little/no exercise): 1.2 • Lightly active (light exercise 1–3 days/week): 1.375 • Moderately active (moderate exercise 3–5 days/week): 1.55 • Very active (hard exercise 6–7 days/week): 1.725 • Extra active (very intense exercise or physical job): 1.9
The BMR Calculator provides insight into your daily calorie needs at rest. When combined with an activity factor, it helps estimate your Total Daily Energy Expenditure (TDEE), which is essential for planning weight loss, maintenance, or gain.
