TDEE Calculator
Estimate daily calorie needs (Total Daily Energy Expenditure).
Estimate how many calories you burn per day in total, then targets for gentle weight loss or gain.
The math behind it
TDEE = BMR × activity factor (1.2 sedentary up to 1.9 very active). A ~500 kcal/day deficit ≈ 0.45 kg (1 lb) loss per week.
Worked example
BMR 1,649 × 1.55 (moderate) ≈ 2,556 kcal/day maintenance.
