TDEE Calculator (Accurate)
About This Calculator
Estimate total daily energy expenditure from body fat percentage, lean body mass, Katch-McArdle BMR, and activity factor for calorie planning.
Frequently Asked Questions
What makes this TDEE calculator different?
This version estimates basal metabolic rate from lean body mass with the Katch-McArdle formula, then multiplies by an activity factor to estimate daily energy expenditure.
Do I need body fat percentage?
Yes. This calculator is most useful when you have a reasonable body fat estimate. If you do not, use a standard TDEE calculator that relies on age, height, weight, and sex.
Is this a medical nutrition plan?
No. It is an educational calorie-planning estimate, not a diagnosis, diet prescription, or replacement for advice from a qualified clinician or registered dietitian.
