Calorie & TDEE Calculator
Estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) based on your activity level.
Daily Calories (TDEE)
2,170 kcal
- Base metabolic rate (BMR)
- 1,400 kcal
Assumptions
- Uses the Mifflin-St Jeor equation, one of several widely used BMR formulas
- Activity multipliers are general estimates, not individualized
How it's calculated
BMR (Mifflin-St Jeor): 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5 (male) or −161 (female). TDEE = BMR × activity multiplier.
Worked example
A 30-year-old female, 68kg, 165cm, moderately active has a BMR and TDEE shown live above.
Frequently asked questions
Which BMR formula does this use?
The Mifflin-St Jeor equation — widely regarded as more accurate than the older Harris-Benedict formula for most adults.
