Short answer
TDEE equals Basal Metabolic Rate multiplied by an activity factor from 1.2 (sedentary) to 1.9 (extra active).
What is the TDEE Calculator?
TDEE is the total calories your body burns in a day, including basal metabolism and all activity. It is the maintenance target for weight-stable eating.
How does the TDEE Calculator work?
Compute BMR with Mifflin–St Jeor, then multiply by the appropriate activity factor.
Formula
Variables
BMRBasal Metabolic Rate (Mifflin–St Jeor)activity1.2 to 1.9 based on exercise frequency
Explanation
The activity multiplier scales BMR to account for movement, digestion, and exercise energy cost.
Examples
Example 1: 30-year-old male, 175/70, moderate
BMR ≈ 1,649, TDEE ≈ 2,556 kcal/day.
Applications
- Weight-loss and gain plans
- Fitness coaching
- Sports nutrition
Advantages
- Individualized to body and activity
- Directly usable for calorie targets
Limitations
- Activity multipliers are estimates — real expenditure varies ±15%
Common mistakes
- Choosing 'very active' for a desk job with 3 weekly gym sessions
Tips
- Track weight for 2–3 weeks — if flat, your true TDEE matches your intake

Practical use cases and industry applications
Understanding TDEE
TDEE is the total calories your body burns in a day, including basal metabolism and all activity. It is the maintenance target for weight-stable eating. Within health calculators, tdee belongs to the nutrition & diet cluster, where it shares terminology and assumptions with closely related tools.
Learning how tdee is calculated
The activity multiplier scales BMR to account for movement, digestion, and exercise energy cost. Working through the variables one at a time — BMR, activity — makes the result reproducible by hand and easier to sanity-check.
Using tdee to make a decision
Weight-loss and gain plans Fitness coaching Sports nutrition Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.
How tdee compares with related measures
energy balance, macronutrient split, hydration, thermic effect all describe adjacent aspects of nutrition & diet. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
Frequently asked questions
TDEE vs maintenance calories?
They're the same thing — the daily calorie amount at which body weight stays steady.
