What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn each day, including your basal metabolic rate (BMR) plus calories burned through activity.

  • BMR = calories burned at complete rest
  • TDEE = BMR × activity multiplier
  • We use the Mifflin-St Jeor formula, considered the most accurate for most people

How to Calculate Your TDEE

TDEE stands for Total Daily Energy Expenditure. It is a daily baseline estimate of how many calories you burn in a day. Eating above this number generally leads to weight gain, while eating below it generally leads to weight loss.

The usual process is simple: estimate your Basal Metabolic Rate, then multiply it by an activity factor. Your BMR is the energy your body uses at rest. Your activity multiplier accounts for movement, exercise, and physical work.

Mifflin-St Jeor Formula

This is the formula used by the calculator above and is considered a strong default for most people.

Men: 10 x weight(kg) + 6.25 x height(cm) - 5 x age + 5
Women: 10 x weight(kg) + 6.25 x height(cm) - 5 x age - 161

Harris-Benedict Equation

Harris-Benedict is an older classic equation. It uses age, weight, height, and sex, but can run a little high for many modern users.

Men: 88.362 + 13.397 x weight(kg) + 4.799 x height(cm) - 5.677 x age
Women: 447.593 + 9.247 x weight(kg) + 3.098 x height(cm) - 4.330 x age

Katch-McArdle Equation

Katch-McArdle estimates BMR from lean body mass, so it can be useful if you know your body fat percentage accurately.

BMR = 370 + (21.6 x lean body mass in kg)

Cunningham Formula

Cunningham is another lean-mass formula, most useful for very lean athletes or people with a reliable fat-free mass measurement.

RMR = 500 + (22 x lean body mass in kg)

How to Use Your TDEE

Lose Weight

Eat below your TDEE. A 500 calorie daily deficit is a common starting point.

Maintain

Eat close to your TDEE and adjust based on your real-world results.

Build Muscle

Eat above your TDEE. The calculator uses a moderate 300 calorie surplus.
