    TDEE Calculator

    Estimate total daily energy expenditure from BMR, steps, workouts, activity components and goal calorie targets, with US or metric inputs.

    Total daily energy expenditure

    TDEE estimates the calories an adult burns in a day. This version keeps the model visible: Mifflin-St Jeor BMR, daily movement, exercise and food thermic effect.

    Component model for total daily energy expenditure.

    Starting estimate
    Actual maintenance calories should be adjusted with several weeks of intake and body-weight trend data. Low-calorie diets require medical supervision.

    Calorie targets

    Simple target-calorie adjustment.

    The goal rows are rough planning ranges, not prescriptions. Targets below BMR or very low daily calories are flagged for review.
