What is the TDEE calculator?

TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity factor — the calories you burn per day. It computes BMR with the Mifflin–St Jeor formula and applies an activity multiplier.

How to use

  1. 1 Enter sex, age, height, and weight.
  2. 2 Choose your activity level.
  3. 3 Read BMR, TDEE, and cut/maintain/bulk targets.

Highlights

Validated formula

Mifflin–St Jeor BMR with activity factors (1.2–1.9).

Goal targets

Shows cut (−500), maintain, and bulk (+500) calories.

常见问题

BMR vs TDEE?+

BMR is what you burn at rest; TDEE adds activity for your total daily burn.

How much to eat to lose weight?+

Eating ~500 kcal/day below TDEE targets roughly 0.5 kg per week.

How do I pick an activity factor?+

Choose 1.2 (sedentary) to 1.9 (very active) based on exercise frequency.
