Methodology and limitations
Last reviewed:
Methodology
Estimates basal metabolic rate with the Mifflin-St Jeor equation, then multiplies by an activity factor to estimate total daily energy expenditure (TDEE).
Limitations
General estimate only. Individual metabolism, medical conditions, and training load vary. Consult a healthcare provider for personalized nutrition guidance.

How to Estimate TDEE
Estimate total daily energy expenditure from your body stats and activity level, then compare maintenance and goal calorie ranges.
Method used
The calculator estimates basal metabolic rate with the Mifflin-St Jeor equation, then multiplies BMR by the selected activity factor to estimate TDEE.
TDEE = BMR x activity multiplier
Practical example
A moderately active adult enters sex, age, height, weight, and activity level to estimate maintenance calories and compare goal calorie ranges.
- Age, biological sex, height, and weight
- Imperial or metric units
- Activity level from sedentary to extra active
The result estimates BMR, maintenance calories, and daily calorie ranges for common weight goals.
Assumptions
- BMR is estimated with the Mifflin-St Jeor equation.
- Activity level is an approximation chosen by the user.
- The output is an educational estimate, not a medical nutrition plan.
What this includes
- BMR estimate, activity multiplier, TDEE estimate, and goal calorie ranges.
What this excludes
- Medical conditions, medications, pregnancy, lactation, metabolic adaptation, athlete-specific needs, and clinical diet advice.

Frequently Asked Questions
What does TDEE mean?
TDEE means total daily energy expenditure. It estimates how many calories your body uses in a day after combining baseline metabolism with activity.
How is TDEE different from BMR?
BMR estimates calories used at rest. TDEE multiplies that baseline by an activity factor to estimate a full day of energy use.
Is this a medical nutrition recommendation?
No. This is an educational estimate based on common formulas. Medical conditions, medications, training load, and individual metabolism can change real calorie needs.
Which activity level should I choose?
Pick the level that best matches your typical week, not your most active day. Sedentary fits desk work with little exercise; extra active fits physical jobs plus regular training.
How accurate is the Mifflin-St Jeor formula?
Mifflin-St Jeor is widely used in clinical and fitness settings and tends to be more accurate than older BMR equations for most adults, though individual results still vary.
