Find out how many calories you burn each day. Enter your details below to instantly calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor equation.
Calories your body burns at complete rest just to stay alive.
Calories you burn each day including activity — your maintenance level.
BMR is the energy your body uses at rest to power breathing, circulation, and cell repair. The Mifflin-St Jeor equation estimates it from your weight, height, age, and sex — it's the most widely recommended formula today.
TDEE multiplies your BMR by an activity factor to estimate the calories you actually burn in a day. To lose weight, eat below your TDEE; to maintain, eat at it; to gain, eat above it.
