Key Features of Our Calorie Calculator
Precision Calculations

Men: BMR = 88.362 + (13.397 × weight) + (4.799 × height) - (5.677 × age) Women: BMR = 447.593 + (9.247 × weight) + (3.098 × height) - (4.330 × age)
Activity Level Adjustment
Five distinct activity multipliers ensure accurate TDEE (Total Daily Energy Expenditure) estimation:
- Sedentary: 1.2
- Light Activity: 1.375
- Moderate Activity: 1.55
- Very Active: 1.725
- Extreme Activity: 1.9
