Activity

BMR & TDEE Calculator (Imperial)

If you provide a valid body-fat %, we’ll use Katch–McArdle; otherwise, we’ll use Mifflin–St Jeor.

Step 1: Body Composition

Weight (lb): Body Fat %: (0–100, triggers Katch–McArdle if valid)

Gender: Age (years): Height (Feet): Height (Inches):

Activity Level:

Enter minutes per day. Calories auto-calculate based on weight (lb).

Disclaimer about MET Values:

MET values are general estimates; actual burn varies by intensity, fitness level, etc.
One MET is the energy expended at rest; activities are multiples of that baseline.

Additional Notes:

Consult a healthcare or fitness professional when starting a new exercise program.
These formulas and multipliers offer approximate estimates, not exact prescriptions.
