How the TDEE estimate is built
Resting energy comes from a BMR formula, then an activity multiplier projects maintenance intake for planning.
Mifflin-St Jeor
Used as the default BMR formula when body fat is not supplied or when you explicitly choose Mifflin mode.
Katch-McArdle
Auto mode switches here when body fat is present because lean mass can tighten the estimate for trained users.
Total Daily Energy
The component view then shows that maintenance estimate as resting energy plus an approximate activity and digestion split for planning context.
Use the number well
Maintenance calories are a starting estimate. Your scale trend and adherence matter more than formula precision alone.
Frequently Asked Questions About TDEE
These answers match the page's FAQ schema and focus on maintenance calories, formulas, deficits, and macro planning.
What is TDEE and why does it matter?
TDEE is your total daily calorie burn after resting metabolism, movement, training, and digestion are all counted together. It matters because it is the baseline number for fat loss, maintenance, and muscle gain.
What is the difference between BMR and TDEE?
BMR is your resting baseline with no activity layered on top. TDEE uses that baseline and adds daily movement, exercise, and digestion to estimate real-world maintenance calories.
What is the most accurate TDEE formula?
For most adults, Mifflin-St Jeor is the best default. Katch-McArdle can be more precise if you have a trustworthy body-fat measurement because it uses lean mass directly.
How many calories below my TDEE should I eat to lose weight?
For most people, 250 to 500 calories below TDEE is the sustainable range. That usually lands around a 15 to 20 percent deficit, which is much easier to recover from and maintain than an extreme cut.
How often should I recalculate my TDEE?
Recalculate every 10 to 15 pounds of body-weight change or when your activity level shifts meaningfully. New training volume, a more active job, or a long break from activity all justify a refresh.
Why is my TDEE different from other calculators?
Different calculators use different BMR equations, activity multipliers, and rounding logic. Small differences are normal. Larger differences usually come from formula choice or activity-level interpretation.
Can I use TDEE to build muscle?
Yes. TDEE is the foundation for lean bulking. Most natural lifters do best with a surplus of about 250 to 500 calories above maintenance, paired with enough protein and progressive resistance training.
Should I eat my TDEE on rest days?
You can keep calories steady every day or eat slightly less on rest days. The simpler approach is usually better unless you already track well and prefer calorie cycling.
What is NEAT and why does it matter for TDEE?
NEAT is non-exercise activity thermogenesis, which includes walking, standing, chores, and all the extra movement that is not formal exercise. It can create large real-world differences in maintenance calories.
What macros should I eat at my TDEE?
Protein should usually be set first, then carbs and fat can be distributed based on your goal and preferences. For fat loss, higher protein intakes are especially useful for muscle retention and satiety.
How accurate is this TDEE calculator in practice?
It is a planning estimate, not a lab measurement. The best way to tighten it is to compare the calculator's output with 2 to 3 weeks of consistent intake and body-weight trend data.
Methodology and source verification
This calculator estimates resting energy with Mifflin-St Jeor by default and switches to Katch-McArdle when body-fat data is available in auto mode. Maintenance calories are then projected from the selected activity multiplier, and the component bars show an approximate planning split rather than a lab-grade metabolic measurement. It is designed for calorie targeting and nutrition planning, not for diagnosing metabolic conditions or replacing indirect calorimetry.
Mifflin-St Jeor predictive equation
Used as the default resting-energy model and widely referenced in nutrition practice when direct calorimetry is not available.
