Overview

Basal Metabolic Rate (BMR) is the minimum amount of energy your body needs at rest to maintain vital functions such as breathing and circulation. This calculator uses the revised Harris-Benedict equation (Roza & Shizgal, 1984) based on sex, weight, height, and age.

Formula

Male: BMR = 88.362 + (13.397 × weight kg) + (4.799 × height cm) - (5.677 × age) | Female: BMR = 447.593 + (9.247 × weight kg) + (3.098 × height cm) - (4.330 × age) | Example: Male, 30 yrs, 75 kg, 178 cm → BMR ≈ 1,777 kcal/day

How to Use

1. 1Select your sex.
2. 2Enter your age, weight (kg), and height (cm).
3. 3Click the 'Calculate' button.
4. 4Review your BMR result.

Tips

• ✔BMR represents the calories your body burns at complete rest over 24 hours.
• ✔To find Total Daily Energy Expenditure (TDEE), multiply BMR by an activity factor.
• ✔Building lean muscle mass increases BMR, making strength training beneficial for weight management.
• ✔This calculator provides estimates only. For precise metabolic measurements, consult a healthcare provider for indirect calorimetry testing.
