How to Use

  1. Choose units and enter gender, age, height, weight.
  2. Select your activity level.
  3. See your maintenance calories, plus cutting and bulking targets.

Calculation Method

TDEE = BMR × activity factor.

BMR uses Mifflin-St Jeor. Activity factors: Sedentary 1.2 · Lightly active 1.375 · Moderately active 1.55 · Very active 1.725 · Extra active 1.9.

Cutting ≈ TDEE − 500 kcal/day · Bulking ≈ TDEE + 500 kcal/day.
