Calorie / TDEE Calculator

Calculate your BMR and daily calorie needs (TDEE).

How this is calculated
Mifflin-St Jeor: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5 (men) or −161 (women); TDEE = BMR × activity multiplier

Assumptions used in this calculation

  • Formula: Uses the Mifflin-St Jeor equation, generally considered more accurate than the older Harris-Benedict formula for most adults.

About this calculator

The calorie/TDEE calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then scales it by your activity level to find Total Daily Energy Expenditure (TDEE), the calories you burn per day, plus suggested calorie targets for weight loss or gain.

Worked example

70 kg male, 175 cm, 30 years old, moderately active

Result: BMR ≈ 1,649 kcal/day; TDEE ≈ 2,556 kcal/day
