How this calculation works
This calorie and TDEE calculator estimates basal metabolic rate (BMR) with the Mifflin-St Jeor equation, then applies an activity multiplier to estimate total daily energy expenditure. It is useful for setting a starting calorie target, but nutrition needs can change with health conditions, medication, pregnancy, training volume, and clinical goals.
Mathematical formula and logic
TDEE = Mifflin-St Jeor BMR multiplied by the selected activity factor.
Worked example
A moderately active 30-year-old uses the result as a starting maintenance estimate, then adjusts after tracking real-world progress.
Calculation assumptions
- The Mifflin-St Jeor equation provides an estimate, not a laboratory measurement.
- Activity multipliers are broad averages.
- Calorie needs can change with training, illness, pregnancy, and medication.
- Use professional dietary advice for clinical nutrition goals.
