BMR Calculator
Calculate your Basal Metabolic Rate (BMR) - the calories your body needs at complete rest.
ℹ️ About Basal Metabolic Rate
What is BMR?
Your Basal Metabolic Rate is the number of calories your body needs to maintain basic physiological functions like breathing, circulation, and cell production while at complete rest.
Activity Level Multipliers:
| Activity Level | Multiplier | Daily Calories |
|---|---|---|
| Sedentary (little exercise) | 1.2 | BMR × 1.2 |
| Light activity (1-3 days/week) | 1.375 | BMR × 1.375 |
| Moderate activity (3-5 days/week) | 1.55 | BMR × 1.55 |
| Very active (6-7 days/week) | 1.725 | BMR × 1.725 |
| Athlete (2x/day training) | 1.9 | BMR × 1.9 |
Note: BMR calculations are estimates. Individual metabolism can vary based on genetics, muscle mass, and other factors.
