Male BMR (Basal Metabolic Rate) Calculator
Calculate BMR specifically for men using Mifflin-St Jeor and Harris-Benedict equations. Determine daily calorie needs based on activity levels.
About
The Basal Metabolic Rate (BMR) represents the minimum amount of energy your body requires to perform basic life-sustaining functions such as breathing, circulation, and cell production while at rest. For men, BMR is typically higher than for women due to naturally higher muscle mass percentages.
This tool calculates your baseline using two standards: the modern Mifflin-St Jeor equation (considered most accurate for modern populations) and the classic Harris-Benedict equation. Knowing your BMR is the first step in creating a nutrition plan for bulking (muscle gain) or cutting (fat loss).

Reference Data
| Activity Level | Multiplier | Lifestyle Description |
|---|---|---|
| Sedentary | BMR × 1.2 | Desk job, little to no exercise. Most common baseline. |
| Lightly Active | BMR × 1.375 | Light exercise or sports 1-3 days/week. |
| Moderately Active | BMR × 1.55 | Moderate exercise or sports 3-5 days/week. |
| Very Active | BMR × 1.725 | Hard exercise or sports 6-7 days/week. |
| Extra Active | BMR × 1.9 | Very hard exercise, physical job, or 2x training/day. |
