How it works
Made for one clear task.
Total daily energy expenditure, or TDEE, multiplies a basal metabolic rate estimate by a selected activity factor. It can be a practical starting point for understanding daily energy use, but it is not a measured metabolic result or medical prescription.
- Calculates BMR before applying an activity factor
- Includes seated through very active reference levels
- Shows both BMR and the activity-adjusted estimate
Formula references
Compare BMI guidance with the CDC adult BMI guidance. BMR uses the published Mifflin–St Jeor equation; for personalized weight planning, see the NIH Body Weight Planner.

Is TDEE exact?
No. It is an estimate. Individual energy needs vary with health, body composition, medications, and many other factors.
