RBA Calorie Calculator
Easily calculate your daily calorie needs
How It Works

This calculator uses the Mifflin-St Jeor Equation to estimate your BMR (Basal Metabolic Rate) - the amount of energy your body needs at rest.

Your TDEE (Total Daily Energy Expenditure) is then calculated by applying an activity multiplier to your BMR.
