BMR Calculator (Advanced)
Calculate your Basal Metabolic Rate (BMR) based on age, gender, height, and weight. Supports modern and classic formulas.
Your Basal Metabolic Rate
BMR (Calories/day)
Formula Used
BMR represents the calories your body needs at complete rest to maintain
vital functions such as breathing, circulation, and cell production.
What Is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body burns at rest to maintain essential life functions. It accounts for about 60–75% of total daily calorie expenditure.
BMR vs TDEE
BMR measures calories burned at rest, while TDEE includes physical activity. To estimate daily calorie needs, BMR is multiplied by an activity factor.
Which BMR Formula Is Best?
- Mifflin-St Jeor: Most accurate for modern populations
- Harris-Benedict: Traditional but slightly overestimates
Who Should Use a BMR Calculator?
- Weight loss planning
