TDEE Calculator - TDEECalc

Build a practical calorie plan for fat loss, maintenance, or muscle gain—without an account, ads, or tracking.

START WITH A PERSONAL PLAN Calculate your estimated TDEE and BMR, choose a goal and pace, and get a calorie target with personalized protein, carbohydrate, and fat targets. Your active plan stays separate from calculator experiments, so nothing changes unless you confirm it.

LEARN FROM YOUR PROGRESS Log weight and complete weekly check-ins to see trends over time. TDEECalc can compare your formula estimate with an observed estimate and suggest small adjustments that you choose whether to apply.

OPTIONAL APPLE HEALTH CONNECTION With your permission, TDEECalc can read body mass and dietary energy from Apple Health to support observed TDEE estimates. Access is optional and read-only. Raw Health samples are processed on your device and are not copied into app backups or sent to the developer.

USE THE METHOD THAT FITS YOU • Mifflin-St Jeor • Revised Harris-Benedict • Katch-McArdle when body-fat percentage is available • Metric and imperial units • BMI and ideal-weight references • Goal-based calorie and macro planning

PRIVATE BY DESIGN Your profile, plans, calculations, and progress stay on your device. TDEECalc has no account, advertising, third-party analytics, or cross-app tracking. Core calculations work offline.

TDEECalc provides educational wellness estimates, not medical advice. Results are starting estimates and may differ from your actual needs.
