TDEE Calculator US
Estimate your Total Daily Energy Expenditure (TDEE) — the calories you burn each day — from your BMR and activity level.
General estimate using standard formulas — not medical or dietary advice. For personalised guidance, speak to a qualified professional.
How it works
Enter your sex, age, height and weight, and choose an activity level. The calculator finds your BMR with the Mifflin–St Jeor equation and multiplies it by an activity factor to estimate your TDEE, then shows typical calorie targets for maintaining, losing or gaining weight.
Frequently asked questions
What is TDEE?
Total Daily Energy Expenditure is an estimate of all the calories you use in a day, including rest, activity and digestion. It is often called your maintenance calorie level.
How is TDEE calculated?
It multiplies your BMR by an activity factor ranging from about 1.2 (sedentary) to 1.9 (extremely active).
What is the difference between BMR and TDEE?
BMR is resting calories only; TDEE adds the energy from daily activity and digestion on top of BMR.
Which activity level should I choose?
Pick the one that best matches a typical week. Many people overestimate, so if unsure, a more conservative level is often closer to reality.
How accurate is a TDEE estimate?
It is a broad estimate because activity multipliers are averages. Use it as a reference point, not an exact figure.
Is this medical or nutrition advice?
No. It is general educational information. For personalised guidance, consult a healthcare professional or registered dietitian.
What TDEE represents
Total Daily Energy Expenditure (TDEE) estimates all the calories your body uses in a typical day — not just at rest, but including movement and digestion. It is the figure most people mean by their "maintenance" energy level: the amount that, on average, keeps body weight stable.
How it is estimated
TDEE starts from your BMR (resting calories) and multiplies it by an activity factor: roughly ×1.2 for sedentary, ×1.375 lightly active, ×1.55 moderately active, ×1.725 very active and ×1.9 extremely active. So a BMR of 1,600 with a moderate lifestyle gives a TDEE of about 2,480.
The four components
TDEE is made up of your BMR, the energy you burn through deliberate exercise, the calories used in everyday non-exercise movement (sometimes called NEAT), and the thermic effect of food — the energy used to digest what you eat. Activity and NEAT are where daily totals vary most between people.
Treat it as a starting reference
Activity multipliers are broad averages, so a TDEE estimate is a starting point rather than an exact number. Real needs vary day to day and person to person. For decisions about nutrition or any health condition, a doctor or registered dietitian can give guidance suited to you.
