  2. Enter the height.
  3. Enter the age.
  4. Choose the sex.
  5. Choose the activity level.
  6. Read off your tdee (maintenance calories), together with bmr (resting calories) — the calculator updates automatically, with no button to press.

Formula

The TDEE Calculator uses the formula:

TDEE (maintenance calories) = (10 × Weight + 6.25 × Height - 5 × Age + Sex) × Activity level

Worked example

For example, with weight of 70 kg, height of 170 cm, age of 30 years and sex of Male and the other inputs, the tdee (maintenance calories) is 2,507.

Inputs used
Weight 70 kg
Height 170 cm
Age 30 years
Sex Male
Activity level Moderate (3–5 days/week)
Results
TDEE (maintenance calories) 2,507
BMR (resting calories) 1,618

Key terms explained

BMR
Basal Metabolic Rate — the calories your body burns at complete rest to maintain basic functions.
TDEE
Total Daily Energy Expenditure — the calories you burn in a day including all activity.

Frequently asked questions

TDEE, total daily energy expenditure, is the calories you burn in a day including activity. It is your BMR multiplied by an activity factor.

This tool finds BMR with the Mifflin-St Jeor formula, then multiplies by an activity factor from 1.2 (sedentary) to 1.9 (very active).

Eat around your TDEE to maintain weight, below it to lose and above it to gain. A 500-calorie daily deficit loses about 0.45 kg a week.

It is a solid starting point, but real needs vary with body composition and genetics. Adjust based on how your weight actually changes.

What Is a Healthy Body Fat Percentage?

For men, a healthy body fat percentage is roughly 10–20%, and for women about 18–28%, with women naturally carrying more essential fat. Athletes are often lower, while levels well above these ranges raise health risks.
