TDEE estimate
The result shows total daily energy expenditure and the BMR behind it.
Current estimate
$2,693 per day
Estimated total daily energy expenditure using a 1.55 activity factor.
Supporting details
- BMR: $1,738
- Activity factor: 1.55
Explanation
How it works
TDEE is easier to use when the basal metabolic rate and activity factor are both visible, because the final number then has context.
Audience
Who should use this
Enter your current metrics, choose the activity level that best matches your routine, and compare the output with your current intake.
Common questions
This page is more explicit about TDEE and uses the activity multiplier as the key planning input.
Yes. The TDEE output is a practical reference point before you set maintenance, deficit, or surplus goals.
