About This Calculator

This tool estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, which calculates the calories your body burns at complete rest based on your age, sex, height, and weight. It then multiplies BMR by a standard activity factor (ranging from 1.2 for sedentary to 1.9 for extra active) to produce your Total Daily Energy Expenditure (TDEE). This is particularly useful for anyone planning a calorie-controlled diet, as TDEE represents the approximate number of calories you need each day to maintain your current weight. Keep in mind that all equations provide estimates; individual metabolism can vary due to genetics, muscle mass, and other factors.

FAQ

Which formula do you use?
We use the Mifflin-St Jeor equation, which is widely accepted for estimating BMR in adults.
What's the difference between BMR and TDEE?
BMR is the energy your body needs at complete rest. TDEE includes daily activity: TDEE = BMR x activity factor.
Is this accurate for athletes or very lean individuals?
Equations provide estimates. Highly muscular or very lean body types can deviate; consider tracking intake/weight or using additional measures.
Can I lose weight by eating below TDEE?
Generally yes, a modest calorie deficit leads to weight loss. Consult a healthcare professional before making major diet changes.
