TDEE calculator
Total daily energy expenditure multiplies BMR by an activity factor. Choose the level that best matches a typical week—not your best week.
Estimated TDEE
2124
kcal / day
TDEE across activity levels (same person)
Using your entered age, height, weight, and sex, this shows TDEE at each standard activity factor. Highlighted bar matches your selected activity. Educational illustration only — not a diagnosis or personal target.
Activity factors are commonly used multipliers paired with Mifflin–St Jeor BMR.
