About this tool

Total daily energy expenditure estimates how many calories you actually burn in a day, once your activity is taken into account. It builds on your basal metabolic rate by applying a multiplier for how active you are.

This calculator estimates your BMR with the Mifflin-St Jeor equation, then applies a standard activity factor. It is a general estimate, not medical or dietary advice; real needs vary from day to day. Consult a professional for personalized guidance. Your data stays in your browser.
