About
TDEECalculator.tools is a free Total Daily Energy Expenditure calculator designed to help people estimate how many calories they burn each day and turn that estimate into practical calorie and nutrition targets.
Enter your age, sex, height, weight, and activity level to estimate your Basal Metabolic Rate (BMR) and daily maintenance calories. Users who know their body-fat percentage can optionally enter it for a Katch-McArdle-based BMR estimate instead of the default Mifflin-St Jeor method.
The results go beyond a single TDEE number. Users can review calorie targets for maintaining, losing, or gaining weight, compare estimated calorie needs across activity levels, explore macro targets, and view additional body metrics such as BMI and estimated ideal-weight ranges.
TDEECalculator.tools is free to use, requires no account or registration, supports both imperial and metric measurements, and includes clear explanations of the formulas, assumptions, activity multipliers, and limitations behind its estimates.
