TDEE & Calorie Calculator

Calculate your Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor equation — the most accurate BMR formula for most people.

BMR = (10×kg) + (6.25×cm) − (5×age) + 5
TDEE = BMR × Activity Multiplier

Understanding TDEE & BMR

BMR vs TDEE

BMR is the calories your body burns at complete rest. TDEE accounts for your actual activity level — it's what you actually need to eat to maintain your weight.

Why Mifflin-St Jeor?

Published in 1990 and validated across large populations, Mifflin-St Jeor is considered the most accurate predictive equation for BMR, outperforming the older Harris-Benedict formula.

Macro Flexibility

The 30/40/30 split is a balanced starting point. Athletes or those on specific diets may prefer higher protein (35–40%) or lower carbs. Adjust based on your goals and tolerance.
