About this calculator
Using TDEE correctly
The TDEE Calculator estimates your total daily energy expenditure by combining your resting calorie needs with your activity level. It helps estimate how many calories you may need to maintain your current weight.
This tool is commonly used to set practical calorie targets for maintenance, fat loss, or muscle gain. It can make nutrition planning easier by giving a clear baseline to start from.
Activity levels and real-life routines change over time, so TDEE should be treated as a dynamic estimate. Use weekly trends, energy levels, and progress data to refine your plan gradually.
Method overview
How this calculation works
TDEE builds on BMR and adjusts for activity level to estimate daily maintenance calories.

Tips for responsible use
- Use your result as a starting point, then review how your body responds over time.
- Track trends under similar conditions instead of focusing on a single reading.
- Combine this estimate with lifestyle context like sleep, activity, stress, and nutrition quality.
- BMR is estimated using the Mifflin-St Jeor formula, then multiplied by an activity factor: 1.2 for sedentary, 1.375 for lightly active, 1.55 for moderately active, 1.725 for very active, and 1.9 for extra active.

FAQ
Common questions about the TDEE Calculator
- How was my TDEE calculated?
- BMR is estimated using the Mifflin-St Jeor formula, then multiplied by an activity factor: 1.2 for sedentary, 1.375 for lightly active, 1.55 for moderately active, 1.725 for very active, and 1.9 for extra active.
- What activity level should I choose?
- Choose the level that honestly reflects your typical week, not your best week. If you are between levels or unsure, selecting one tier lower is a safer starting point — it is easier to adjust up than to over-eat from an inflated estimate.
- Is TDEE the same as my calorie goal?
- TDEE estimates your maintenance level — the calories needed to stay at your current weight. From there, subtract calories to support fat loss or add a modest surplus to support muscle building, depending on your goal.
- Why might my actual intake differ from TDEE?
- TDEE is a population-level estimate. Individual factors like sleep quality, stress, non-exercise movement (NEAT), and metabolic variation mean real needs can differ noticeably. Use 2–3 weeks of real-world data to calibrate.
- How often should I recalculate TDEE?
- Recalculate every few weeks, or whenever weight, activity patterns, or training volume change meaningfully. TDEE is a dynamic estimate, not a fixed number.
- Can TDEE be used for both fat loss and muscle gain?
- Yes. A daily deficit below your TDEE supports fat loss planning; a moderate surplus above TDEE can support muscle building when paired with resistance training. TDEE is the common starting point for both.
