Enter your age, sex, height, weight and activity level. The calculator applies the Mifflin-St Jeor formula to estimate your daily maintenance calories.
Total Daily Energy Expenditure is the calories you burn per day, including your basal metabolic rate plus activity. It is your maintenance calorie level.
This tool finds BMR with the Mifflin-St Jeor equation, then multiplies by an activity factor (1.2 sedentary to about 1.9 very active) to estimate TDEE.
Eat below your TDEE to lose weight and above it to gain. A deficit or surplus of around 500 calories a day changes weight by roughly half a kilo per week.
