How It Works
Enter your gender, age, height, and weight. Your BMR updates instantly using the Mifflin-St Jeor equation.
Men: BMR = 10W + 6.25H − 5A + 5. Women: BMR = 10W + 6.25H − 5A − 161 (W in kg, H in cm, A in years)
Example
A 30-year-old male, 175cm, 70kg has a BMR of about 1,674 calories/day.
Frequently Asked Questions
- What is BMR used for?
- BMR is the baseline for estimating your total daily calorie needs — multiply it by an activity factor to get your maintenance calories.
- Why does gender affect the result?
- Men typically have more lean muscle mass than women at the same weight, which raises resting energy expenditure — the formula accounts for this with a fixed offset.
