About this tool
Combines your Basal Metabolic Rate with an activity multiplier to estimate your Total Daily Energy Expenditure (TDEE) — the number of calories you burn in a typical day, useful for weight maintenance, loss, or gain planning.

Frequently asked questions
- How do I use TDEE to lose weight?
- A common approach is eating roughly 500 calories below your TDEE per day, which corresponds to about one pound of fat loss per week — consult a professional before making significant changes.
- Why does activity level matter so much?
- Activity level typically changes your calorie needs by 20-90% above your resting BMR, making it one of the biggest levers in the estimate.
